WASTE MANAGEMENT

EXECUTIVE SUMMARY

Waste management is an important part of the urban infrastructure as it ensures the

protection of the environment and of human health .It is not only a technical environmental

issue but also a highly political one. Waste management is closely related to a number of

issues such as urban lifestyles, resource consumption pattern, jobs and income levels, and

other socio-economic and cultural factors.

Waste prevention and minimization has positive environmental, human health and safety

and economic impacts. Implementing a “less is better” concept provides better protection of

human health and safety by reducing exposures, generating less demand for disposal on the

environment. Less Waste also lowers disposal cost.

Arising quality of life and high rates of resource consumption patterns have had an

unintended and negative impact on the urban environment – generation of wastes far

beyond the handling capacities of urban governments and agencies. Cities are now

grappling with the problems of high volumes of waste, the costs involved, the disposal

technologies and methodologies and the impact of wastes on the local and global

environment.

But these problems have also provided a window of opportunity for cities to find solutions-

involving the community and the private sector, involving innovative technologies and

disposal methods, and involving behavior changes and awareness raizing. These issues have

amply demonstrated by good practices from many cities around the world. There is a need

for a complete rethinking of “waste”- to analyze if waste is indeed waste.

WASTE MANAGEMENT

A rethinking that calls for,

WASTE to become WEALTH

REFUSE to become RESOURCE

TRASH to become CASH

There is a clear need for the current approach of waste disposal that is focused on

municipalities and uses high energy / high technology , to move more towards waste

processing and waste recycling (that involves public-private partnerships , aiming for

eventual waste minimization –driven at the community level, and using low energy/low

technology resources . Some of the defining criteria for future waste minimization program

will include deeper community participation, understanding economic benefits/recovery of

waste, focusing on life cycles (rather than end-of-pipe solutions, decentralized

administration of waste, minimizing environmental impacts, reconciling investment cost

with long-term goals.

WASTE MANAGEMENT

AIM OF THE PROJECT:

To study the waste management situation and to understand the process that goes behind

it. That will help me create an awareness to protect public health, safety and to provide a

safe working environment. All efforts of mine are to learn how to reduce waste without

compromising health.

OBJECTIVES OF THE PROJECT:

The basic objective of this project is creating awareness about waste management and the

steps taken to reduce waste prevailing in the city.

LIMITATIONS OF THE PROJECT:

The only limitation or rather, an opportunity that could have taken this study to another

level, I felt was, in terms of my inability to go to other places across India or overseas to see

for myself the situation there and how the local authorities are tackling it. Someday, an

opportunity to this will certainly bring a new dimension to my understanding of this project.

METHODOLOGY OF DATA COLLECTION:

Interviews with concerned people from the industry.

Research using reading material like articles, journals, newspapers, UN reports.

Field work involving visit to ITC, Bisleri, MPCB.

WHAT IS WASTE?

Page 4: Waste Management

WASTE MANAGEMENT

Waste is rubbish, trash, garbage or junk is unwanted or undesired material. There are a

number of different types of waste. It can exist as a solid, liquid or gas or as waste heat.

When released in the latter two states the wastes can be referred to as emissions. It is usually

strongly linked with pollution. Waste may also be intangible in the case of wasted time or

wasted opportunities. The term waste implies things, which have been used inefficiently or

inappropriately.

Some components of waste can be recycled once recovered from the waste stream. E.g.

plastic bottles, metals, glass or paper The biodegradable component of wastes e.g. paper &

food waste) can be composted or anaerobic digested to produce soil improvers and

renewable fuels. If it is not dealt with sustainably in this manner biodegradable waste can

contribute to greenhouse gas emissions and by implication climate change.

There are two main definitions of waste. One view comes from the individual or the

organization preceding the material, the second is the view of government, and is set out in

different acts of waste management. The two have to combine to ensure the safe and legal

disposal of the waste.

WASTE MANAGEMENT

Below waste is categorized according to the sector generating it. Different sectors generate

specific types of waste, and collection systems are adapted to the sectors and their specific

waste.

Information on specific waste sectors:

Waste from the building and construction sector

Packaging waste

Waste from households

Waste from industry

Waste from institutions , trade and offices

Waste from power plants and wastewater treatment plants.

TYPES OF WASTE

5

Page 6: Waste Management

WASTE MANAGEMENT

Waste can be divided into many different types. The most common methods of

classification are by their physical, chemical and biological characteristics. One important

classification is by their consistency. Solid waste is waste materials that contain less than

70% water. This class includes as household garbage, some industrial waste, some mining

waste, and oilfield waste such as drill cutting. Liquid wastes are usually waste water that

contains less than 1 % solids. Such waste may contain high concentrations of dissolved salts

and metals. Sludge is a class of waste between liquid and solid. They usually contain

between 3% & 25% solids, while the rest of the material is water dissolved materials.

INDUSTRIAL WASTE

6

Page 7: Waste Management

WASTE MANAGEMENT

Industrial waste is waste type produced by industrial factories, mills and mines. It has

existed since the outset of the industrial revolution. Toxic waste and chemical waste are

two designations of industrial waste. It is considered hazardous as they may contain toxic

substance. Certain types of household waste are also hazardous. Hazardous waste could be

highly toxic to humans, animals, and plants; are corrosive, highly inflammable or explosive;

and react when exposed to certain things e.g. gases. India generates around 7 millions tones

of hazardous wastes every year, most of which is concentrated in 4 states: Andhra Pradesh,

Bihar, Uttar Pradesh, and Tamil Nadu. In the industrial sector, the major generators of

hazardous waste are the metal, chemical paper, pesticide, dye, refining, and rubber goods

industries. Direct exposure to chemicals in hazardous waste such as mercury and cyanide

can be fatal.

HAZARDOUS WASTE

Hazardous waste is a waste with properties that make it dangerous or potentially harmful to

human health or the environment. The universe of hazardous wastes is large and diverse.

Hazardous waste can be liquids, solids, contained gases, or sludge’s. They can be the by-

products of manufacturing processes or simply discarded commercial products like cleaning

fluid or pesticides. It exhibits at least one of four characters – ignitability, corrosivity,

reactivity, or toxicity. Hazardous waste is regulated under the Resource Conservation and

the Recovery Act (RCRA) Subtitle.

HOSPITAL WASTE

Hospital waste is generated during the diagnosis, treatment, or immunization of the human

beings or the animals or in research activities in these fields or in the production or testing

of biological. It may include wastes like sharps, soiled waste, disposables, anatomical,

waste, discarded medicines, chemical waste etc. These are in the form of disposable

syringes, swabs, bandages, body fluids, human excreta etc. This waste is highly infectious

and can be a serious threat to the human health if not managed in a scientific and

discriminate manner. It has been roughly estimated that 4 kg of waste generated in hospital

at least 1 kg would be infected.

WASTE MANAGEMENT

MUNICIPAL SOLID WASTE

Municipal solid waste consists of household waste, construction and demolition debris,

sanitation residue, and waste from streets. This garbage is generated mainly from residential

and commercial complexes. With rising urbanization and change on lifestyle and food

habits, the amount of municipal solid waste has been increasing rapidly and its composition

changing. In 1947 cities and towns in India generated an estimates 6 millions tones of solid

waste; in 1997 it was about 48 millions tones.

WASTE MANAGEMENT

RADIOACTIVE WASTE

Radioactive waste arises primarily from nuclear generation; smaller quantities are derived

from military sources and a variety of uses in medical, industrial and university

establishments. There are many types of radioactive waste which can be classified either

according to their radioactive properties or according to the sources from which they

originated. Low level radioactive wastes generally consist of contaminated laboratory

debris, biological materials, building materials. High level of radioactive waste consists

of spent fuels from nuclear power reactors, together with liquid and solid residues from

reprocessing of spent fuels.

NON-HAZARDOUS WASTE

Non-hazardous are those that pose no immediate threat to human health and the

environment. Household garbage is included into this category.

WASTE MANAGEMENT

WHAT IS MANAGEMENT?

The term “management” characterizes the process of and/or the personnel leading and

directing all or part of an organization (often a business) through the deployment and

manipulation of resources (human, financial, material, intellectual or intangible)

According to the Oxford English Dictionary, the word “mange” comes from the Italian

mangier (to handle-especially a horse), which in turn derives from the Latin Manus (hand).

The French word management (later management) influenced the development in meaning

of the English word management in the 17th and 18th centuries.

11

WASTE MANAGEMENT

WASTE MANAGEMENT

Waste management is the collection, transport, processing (waste treatment), recycling or

disposal of waste materials, usually ones produced by human activity, in an effort to reduce

their effect on human health or local aesthetics or amenity. Waste management can involve

solid, liquid or gaseous substances with different methods and fields of expertise for each.

Waste management practices differ for developed and developing nations, for urban and

rural areas and for residential, industrial and commercial producers. Waste management for

non-hazardous residential and institutional waste in metropolitan areas is usually the

responsibility of the local government authorities, while management for non-hazardous

commercial and industrial waste is usually the responsibility of the generator.

Basic waste management principles of waste management are to:

Reduce environmental and health impacts and

To save resources.

12

Page 13: Waste Management

WASTE MANAGEMENT

PURPOSE OF WASTE MANAGEMENT

Protect people who handle waste items from accidental injury.

Prevent the spread of infection to healthcare workers who handle the waste.

Prevent the spread of infection to the local community.

Safely dispose of hazardous materials.

Open piles of waste should be avoided because they are a risk to those who scavenge and

unknowingly reuses contaminate items.

THE HISTORY OF WASTE MANAGEMENT

Historically the amount of waste generated by human population was insignificant mainly

due to the low population densities, coupled with the fact there was very little exploitation

of natural resources. Common waste produced during the early ages were mainly ashes and

human & biodegradable wastes, and these were released back into the ground locally, with

minimal environmental impact.

Before the widespread use of metals, wood was widely used for most applicants. However,

reuse of wood has been well documented nevertheless, it is once again well documented

that reuse and recovery of such metals have been carried out by earlier humans.

With the advent of industrial revolution, waste management became a critical issue. This

was due to the increase in the population and the massive migration of people to the

industrial towns and cities from rural areas during the 18th century. There was a consequent

increase in the industrial and domestic waste posing threat to human health and

environment.

13

Page 14: Waste Management

WASTE MANAGEMENT

Waste has played a tremendous role in the history. The plague, cholera, and typhoid fever,

to mention a few, were diseases that altered the populations of many countries.

They were perpetuated by filth that harbored rats and contaminated water supply. It was not

uncommon for everybody to throw their waste and human waste out of the window which

would decompose in the street.

14

Page 15: Waste Management

WASTE MANAGEMENT

WASTE MANAGEMENT CONCEPTS

There are number of concepts about waste management which vary in their usage between

countries or regions. Some of the most general, widely used concepts include:

Waste hierarchy – The waste hierarchy refers to the “3 Rs” reduce, reuse and recycle

which classify waste management strategies according to their desirability in terms of waste

minimization. The waste hierarchy remains the cornerstone of most waste minimization

strategies. The aim of the waste hierarchy is to extract the maximum practical benefits from

products and to generate the minimum amount of waste.

Extended producer responsibility- Extended producer responsibility (EPR) is a

strategy designed to promote the integration of all costs associated with products throughout

their lifecycle (including end-of-life disposal costs) into the market price of the product.

Extended producer responsibility is meant to impose accountability over the entire lifecycle

of products and packaging introduced to the market. This means that firms which

manufacture, import and/or sell products are required to be responsible for the products after

their useful life as well as during manufacture.

Polluter pays principle- The polluter pays principle is a principle where the polluting

party pays for the impact caused to the environment. With respect to waste management,

this generally refers to the requirement for a waste generator to pay for appropriate disposal

of the waste.

15

Page 16: Waste Management

WASTE MANAGEMENT

THE WASTE HIERARCHY

There are a number of concepts about waste management, which vary in their usage

between countries or regions. The waste hierarchy:

Reduce

Reuse

Recycle

REDUCE

Waste minimization or reduction is a process of waste management at the top of the Waste

hierarchy.

Waste management has traditionally been focused on processing wastes after they are

created rather than reducing their production. This latter process usually requires specific

knowledge of the production process, unlike post creation processes such as re-use,

recycling, composting or waste –to-energy.

16

Page 17: Waste Management

WASTE MANAGEMENT

To reduce waste volume, it is first necessary to determine the composition of the waste and

reason for its creation. Therefore, no general procedures apply to the general case, and each

case must be processed individually.

Commercial waste is often produced because of delivery procedures set by a central supply

system, or it may be the result of the machinery used, which often requires considerable

investment for appropriate upgrades.

Most waste comes from the (manufacturing) industry, agriculture, construction and

demolition industries. Household waste only constitutes a small percentage of overall waste,

and therefore has less affect on the overall waste volume.

REUSE

Reuse is using an item more than once. This includes conventional reuse where the item is

used a number of times for the same function, and new life reuse where a new use is found

for the item. It is distinct from recycling, where the used item is broken down into raw

materials which are used to make new items.

Reuse can have both financial and environmental benefits, and either of these can be the

main motivation for it. The financial motivation historically did, and in the developing

world still does, lead to very high levels of reuse, but rising wages and consequent

consumer demand for the convenience of disposable products made the reuse of low value

items such as packaging uneconomic in richer countries, leading to the demise of many

reuse schemes – indeed we have gone a long way down the road to being a disposable

society. Current environmental awareness is gradually changing attitudes and regulations,

such as the new packaging regulations, are gradually beginning to reverse the situation. The

classic example of conventional reuse is the doorstep delivery of milk in reusable bottles;

other examples include the retreading of tyres and the use of plastic delivery trays (transit

packaging) in place of cardboard cartons

17

Page 18: Waste Management

WASTE MANAGEMENT

RECYCLING

Recycling is the reprocessing of materials into new products. Recycling prevents useful

material resources being wasted, reduces the consumption of raw materials and reduces

energy usage, and hence greenhouse gas emissions, compared to virgin production.

Recycling is a key concept of modern waste management and is the third components of the

waste hierarchy. Recyclable materials, also called “recyclables” or “recyclates” may

originate from a wide range of sources including the home and industry. They include glass,

paper, aluminum, asphalt, iron, textiles and plastics. Biodegradable waste, such as food

waste or garden waste is also recyclable with the assistance of microorganisms through

composting or anaerobic digestion.

Some waste management experts have recently incorporated a fourth R: “Rethink” with the

implied meaning that the present system may have fundamental flaws, and that a thoroughly

effective system of waste management may need an entirely new way of looking at waste.

Some re-think solutions may be counterintuitive, such as cutting fabric patterns with slightly

more “waste material” left the now larger scraps are than used for cutting small parts of

pattern, resulting in a decrease in net waste. This type of solution is by no means limited to

the clothing industry. Source reduction involves efforts to reduce hazardous waste and other

materials by modifying industrial production. It also involves changes in manufacturing

technology, raw materials input, and product formulation. At times the term “pollution

prevention” may refer to source reduction.

18

Page 19: Waste Management

WASTE MANAGEMENT

ADVANTAGES OF RECYCLING AND REUSE OF WASTE WATER

Reduction in interference with the environment will increase by reducing or eliminating

the effluent discharge. It is an effective approach towards ‘Sero Liquid Discharge’.

Recycled water can be treated to almost any standards hence is suitable for any end user.

Reduction in “Fresh water” intake and the costs associated with it.

Reduction in “disposal volume” and the costs associated with it.

Recycled water is like creation of “New”, “In – house” source of good quality water

largely unaffected by external factors. In areas where “Fresh Water” cost is presently high

or likely to be hiked, the recycled water shall provide “ongoing savings”.

Recycling and reuse is an approach towards ISO – 14000

Sources of waste water for recycle and reuse.

In a running industry the water in untreated or treated form is used for various

applications. Hence the waste water is being generated in various sections. The sources

typically are treated effluent from effluent treatment plant, boiler blow down, floor

washings.

End use of recycled water

The recycled water generated from waste water can be used for various

applications after suitable post – treatment like process water, boiler feed cooling tower,

chillers, as soft water gardening etc.

19

WASTE MANAGEMENT

TYPES OF WASTE MANAGEMENT

URBAN WASTE MANAGEMENT

The overall goal of urban solid waste management is to collect, treat and dispose of

solid wastes generated by all urban population groups in an environmentally and socially

satisfactory manner using the most economical means available.

Local governments are usually authorized to have responsibility for providing solid waste

management services, and most local government laws give them exclusive ownership over

waste once it has been placed outside a home or establishment for collection.

As cities grow economically, business activity and consumption patterns drive up solid

waste quantities.

At the same time, increased traffic congestion adversely affects the productivity of the

solid waste fleet.

Productivity loss is exacerbated by longer hauls required of the fleet, as open lands for

disposal are further and further away from urban centers.

The challenge is to rationalize worker and vehicle performance, while expanding

services to a growing urban population.

MUNICIPAL WASTE MANAGEMENT

Over the last few years, the consumer market has grown rapidly leading to products being

packed in cans, aluminium foils, plastics, and other such non biodegradable items that cause

incalculable harm to the environment. In India, some municipal areas have banned the use

of

Plastics and they seem to have achieved success.

For example, today one will not see a single piece of plastic in the entire district of Latah

where the local authorities imposed a ban on plastics in 1998.

20

Page 21: Waste Management

WASTE MANAGEMENT

Other states should follow the example of this region and ban the use of items that cause

harm to the environment.

One positive note is that in many large cities, shops have begun packing items in reusable

or biodegradable bags.

Certain biodegradable items can also be composted and reused. In fact proper handling

of the biodegradable waste will considerably lessen the burden of solid waste that each city

has to tackle.

RADIOACTIVE WASTE MANAGEMENT

Radioactive waste management involves dealing safely with the wastes from processes

involving radioactivity.

This waste comes from a number of sources, and ranges from paper towels used in

hospitals to nitric acid solution formed as a result of reprocessing nuclear fuel.

Most radioactive waste is currently stored safely on major sites under license from the

Health and Safety Executive’s Nuclear Installations Inspectorate and is subject to strict

regulatory control.

21

Page 22: Waste Management

WASTE MANAGEMENT

SEGREGATION

Certain things that are not needed around the house are kept aside to be sold to the

kabadiwala or the man who buys old items. These items are newspapers, used bottles,

magazines, carry bags, old exercise books, oilcans, etc. This is one form of segregation,

which is done as a routine in all households in India. Separating our waste is essential as the

amount of waste being generated today causes immense problem. Segregation of municipal

solid waste can be clearly understood by schematic representation. Certain items are not

22

Page 23: Waste Management

WASTE MANAGEMENT

biodegradable but can be reused or recycled.In fact, it is believed that a larger portion can

be recycled; a part of it can be converted to compost, and only a smaller portion of real

waste that has no use and has to be discarded.

Household waste should be separated daily into different bags for the different

categories of waste such as wet and dry waste, which should be disposed of separately.

One should also keep a bin for toxic wastes such as medicines, batteries, dried paint, old

bulbs, and dried shoe polish. Wet waste, which consists of leftover foodstuff, vegetable

peels, etc., should be put in a compost pit and the compost could be used as manure in the

garden. Dry waste consisting of cans, aluminium foils, plastics, metal glass, and paper

could be recycled. If we do not dispose of the waste in a more systematic manner, more

than 1400 sq. km of land, which is size of the city of Delhi, would be required in the

country by the year 2047 to dispose of it.

Waste can be segregated as

1. Biodegradable.

2. Non biodegradable

Biodegradable waste:

It includes organic waste, e.g. kitchen waste, vegetables, fruits, flowers leaves from the

garden, and paper.

Non biodegradable waste:

It can be further segregated into.

a) Recyclable waste – plastics, paper, glass, metal, etc.

b) Toxic waste – old medicines, paints, chemicals, bulbs, spray cans, fertilizer and pesticide

containers, batteries, shoe polish.

c) Soiled – hospital waste such as cloth soiled with blood and other body fluids Toxic and

soiled waste must be disposed of with utmost care.

23

WASTE MANAGEMENT

PROCEDURE OF WASTE MANAGEMENT

The above four key aspects of waste management – disposal, processing, recycling and

minimization – is presented here in the form of a dual axis continuum, which helps in

understanding the actions to be taken, and in building a comprehensive waste management

strategy for local governments in cities for developing countries.

Waste Processing Waste Minimization

Waste Disposal Waste Recycling

Waste Disposal:

Historically, efforts in the management of waste have focused primarily on

the disposal part of the waste. Whilst there is now a general move towards the recovery of

resources from waste, disposal is still the most common form of managing waste. Dumping,

land filling of waste and incerination are some of the common methods of waste disposal.

Waste Processing Waste Minimization

Waste disposal Waste Recycling

Recycling is the breaking down of materials from waste streams into raw materials, which

are then, reprocessed either in to the same material or a new product, generally including

24

Page 25: Waste Management

WASTE MANAGEMENT

waste separation and material reprocessing. There are various materials that are capable of

being recycled, and technology is advancing to allow the recycling of more materials.

The benefits of recycling do not lie solely in diversion of waste away from disposal but,

even more importantly, in the reduction of the amount of virgin resources that need to be

harvested and processed for the manufacture of new products.

Waste Processing Waste Minimization

Waste Disposal Waste Recycling

Waste processing is the range of activities characterized by the treatment and recovery of

materials or energy from waste through thermal, chemical, or biological means. It also

covers hazardous waste handling. Generally there are two main groups of processes to be

considered,

1. Biological Processes, such as open composting, enclosed composting, anaerobic

digestion, and vermiculture.

2. Thermal processes, such as incerination, and gasification.

25

Page 26: Waste Management

WASTE MANAGEMENT

WASTE DISPOSAL METHODS

Disposal methods for waste products vary widely, depending on the area and the type of

waste material. For example, in Australia the most common method of disposal of solid

household waste is in landfill sites, as it is a large country with a low density population. By

contrast in Japan it is more common for waste to be incinerated, because the country is

smaller and land is scarce. Other waste types will be disposed off in different ways in both

countries.

LANDFILL

Disposing of waste in a landfill is one of the most traditional methods of waste

disposal, and it remains a common practice in most countries. Historically, landfills were

often established in discussed quarries, mining voids or borrow pits. A properly –designed

26

WASTE DISPOSAL

LANDFIILL RESOURCE RECOVERY

Page 27: Waste Management

WASTE MANAGEMENT

and well-managed landfill can be a hygienic and relatively inexpensive method of disposing

of waste materials in a way that minimizes their impact on the local environment. Older,

poorly –designed or poorly – managed landfills can create a number of adverse

environmental impacts such as wind-blown litter, attraction of vermin, and generation of

leach ate where result of rain percolating through the waste and reacting with the products

of decomposition, chemicals and other materials in the waste to produce the leach ate which

can pollute groundwater and surface water.

Another byproduct of the landfills is landfill gas (mostly composed of methane and carbon

dioxide) which is produced as organic waste breaks down anaerobic ally. This gas creates

odor problems, kills surface vegetation, and is a greenhouse gas. Characteristics of a modern

landfill include methods to contain leach ate, such as clay or plastic lining material.

27

Page 28: Waste Management

WASTE MANAGEMENT

Disposed waste is normally compacted to increase its density and stabilize the new

landform, and covered to prevent attracting vermin (such as mice or rats) and reduce the

amount of wind-blown litter. Many landfills also have a landfill gas extraction system

installed after closure to extract the landfill gas generated by the decomposing waste

materials. Gas is pumped out of the landfill using perforated pipes and flared off or burnt in

a gas engine to generate electricity. Even flaring the gas is a better environmental outcome

than allowing it to escape to the atmosphere, as this consumes the methane, which is far

more potent greenhouse gas than carbon dioxide.

Many local authorities, especially in urban areas, have found it difficult to establish new

landfills due to the opposition from owners of adjacent land. Few people want a landfill in

their local neighborhood. As a result, solid waste disposal in these areas has become more

expensive as material must be transported further away for disposal (or managed by other

methods)

This fact ,as well as growing concern about the impacts of excessive materials

consumption , has given rise to efforts to minimize the amount of orts include taxing or

levying waste sent to landfill , recycling the materials , converting material to energy,

designing products that use less material , and legislation mandating that manufactures

28

Page 29: Waste Management

WASTE MANAGEMENT

become responsible for disposal costs of products or packaging. A related subject is that of

industrial ecology, where the material flows between industries is studied. The byproducts

of one industry may be a useful commodity to another, leading to a reduced materials waste

stream.

INCINERATION

Incineration is a disposal method that involves combustion of waste material. Incineration

and other high temperature waste treatment systems are sometimes described as “thermal

treatment”. Incinerators convert waste materials into heat, gas, team and ash.

Incineration is carried out both on a small scale by individuals and on a large scale by

industry. It is used to dispose of solid, liquid and gaseous waste. It recognized as a practical

method of disposing of certain hazardous waste materials (such as biological medical

waste). Incineration is a controversial method of waste disposal, due to issues such as

emission of gaseous pollutants.

Incineration is common in countries such as Japan where land is scarcer, as these facilities

generally do not require as much area as landfills. Waste –to-energy (WtE) or energy-from-

waste (EfW) is broad terms for facilities that burn waste in a furnace or boiler to generate

heat, steam and/or electricity. Combustion in an incinerator is not always perfect and there

have been concerns about micro-pollutants in gaseous emissions from incinerator stacks.

Particular concern has focused on some very persistent organics such as dioxins, furans;

PAHs….which may be created within the incinerator and afterwards in the incinerator

plume which may have serious environmental consequences in the area immediately around

the incinerator. On the other hand this method or the more being anaerobic digestion

produces heat that can be used as energy.

RESOURCE RECOVERY

29

Page 30: Waste Management

WASTE MANAGEMENT

A relatively recent idea in waste management has been to treat the waste material as a

resource to be exploited, instead of simply a challenge to be managed and disposed of.

There are a number of different methods by which resources may be extracted from waste:

the materials may be extracted or recycled, or the calorific content of the waste may be

converted to electricity.

The process of extracting resources or value from waste is variously referred to as

secondary resource recovery, recycling and other terms. The practice of treating waste

materials as a resource is becoming more common, especially in metropolitan areas where

space for new landfills is becoming scarcer. There is also a growing acknowledgement that

simply disposing of waste materials is unsustainable in the long term, as there is a finite

supply of most raw materials.

There are a number of methods of recovering resources from waste materials, with new

technologies and methods being developed continuously.

In some developing nations some resource already takes place by way of manual laborers

who sift through un-segregated waste to salvage material that can be sold in the recycling

market. These unrecognized workers called waste pickers or rag pickers are part of the

informal sector, but play a significant role in reducing the load on the Municipalities solid

waste management departments. There is an increasing trend in recognizing their

contribution to the environment and there are efforts to try and integrate them into the

formal waste management systems, which is proven to be both cost effective and also

appears to help in urban poverty alleviation. However, the very high human cost of these

activities including diseases, injury and reduced life expectancy through contact with or

infectious materials would not be tolerated in a developed country.

RECOVERY (RECYCLING)

30

Page 31: Waste Management

WASTE MANAGEMENT

Recycling means to recover for other use a material that would otherwise be considered

waste the popular meaning of “recycling” in the most developed countries has come to refer

to the widespread collection and reuse of various everyday waste materials. They are

collected and sorted into common groups, so that the raw materials from these items can be

used again (recycled).

In developed countries the most common consumer items recycled include aluminum

beverage cans, steel, food and aerosol cans, HDPE and PET plastic bottles, glass bottles and

jars, paperboard cartons, newspapers, magazines and cardboard. Other types of plastic

(PVC, LDPE, PP and PS: see resin identification code) are also recyclable, although not as

commonly collected. These items are usually composed of a single type of material, making

them relatively easy to recycle into new products. The recycling of obsolete computers and

electronic equipment is important, but, more costly due to the separation and extraction

problems. Much electronic waste is sent to Asia, where recovery of the gold and copper can

cause environmental problems (monitors contain lead and various “heavy metals” such as

selenium and cadmium; both are commonly found in electronic items)

Recycled or used materials have to compete in the marketplace with new (virgin) materials.

The cost of collection and sorting the materials often the case in developed countries where

industries producing the raw materials are well-established. Practices such as trash picking

can reduce this value further as choice items are removed9such as aluminum cans). In some

countries, recycling programs are subsidized by deposits paid on beverage containers (see

container deposit legislation)

However, most economic systems do not account for the benefits to the environment of

recycling these materials, compared with extracting virgin materials. It usually requires

significantly less energy, water and other resources to recycle materials than to produce new

materials. For example , recycling 1000 kg of aluminum cans saves approximately 5000 kg

of bauxite ore being mined and prevents the generation of 15.17 tones CO2 greenhouse

gases; recycling steel saves about 95% of the energy used to refine virgin ore.

HEALTH IMPACTS OF WASTE

Modernization and progress has had its share of disadvantages and of the main aspects of

concern is the pollution it is causing to the earth – be it land, air, and waste. With increase in

the global population and the rising demand for food and other essentials, there has been a

rise in the amount of waste being generated daily by each household. This waste is

ultimately thrown into municipal waste collection centers from where it is collected by the

area municipalities to be further thrown into the landfills and dumps. However, either due to

the resource crunch or inefficient infrastructure, not all of this waste gets collected and

transported to the final dumpsites. If at this stage the management and disposal is

improperly done, it can cause serious impacts on health and problems to the surrounding

environment.

Waste is not properly managed; especially excreta and other liquid and solid waste from

household and the community, are a serious health hazard and lead to the spread of

infectious diseases. Unattended waste lying around attracts flies, rats, and other creatures

that in turn spread disease. Normally it is the waste that decomposes and releases a bad

odor. This leads to unhygienic conditions and thereby to a rise in the health problems. This

plague outbreak in Surat is a good example of a city suffering due to the callous attitude of

the local body in maintaining cleanliness in the city. Plastic waste is another cause for ill

health. Thus excessive solid waste that is generated should be controlled by taking certain

preventive measures.

IMPACTS OF SOLID WASTE ON HEALTH

The group at risk from the unscientific disposal of solid waste includes the population in

areas where there is no proper waste disposal method, especially the pre-school children,

waste workers and workers in facilities producing toxic and infectious material. Other high-

risk group includes population living close to a waste dump and those, whose water supply

has become contaminated either due to waste dumping or leakage from landfill sites.

Uncontrolled solid waste also increases risk of injury, and infection.

In particular organic domestic waste poses a serious threat, since they ferments, creating

conditions favorable to the survival and growth of microbial pathogens. Direct handling of

solid waste can result in various types of infectious and chronic diseases with the waste

workers and the rag pickers being the most vulnerable.

Exposure to hazardous waste can affect human health, children being more vulnerable to

these pollutants. In fact, direct exposure can lead to diseases through chemical exposure as

the release of chemical waste into the environment leads to the chemical poisoning. Many

studies have been carried out in various parts of the world to establish a connection between

health and hazardous waste.

Waste from agriculture and industries can also cause serious health risks. Other than this,

co-disposal of industrial hazardous waste with municipal waste can expose people to

chemical and radioactive hazards. Uncollected solid waste can also obstruct storm water

runoff, resulting in the forming of stagnant water bodies that become the breeding ground of

disease. Waste dumped near a water source also causes contamination of the water body or

the ground water source.

Direct dumping of untreated waste in rivers, seas and lakes results in the accumulation of

toxic substances in the food chain through the plants and animals that feed on it

Disposal of hospital and other medical waste requires special attention since this can

create major health hazards. This waste generated from the hospitals, health care centers,

34

Page 35: Waste Management

WASTE MANAGEMENT

medical laboratories and research centers such as discarded syringe needles, bandages,

swabs, plasters and other types of infectious waste are often disposed with the regular non-

infectious waste.

Waste treatment and disposal sites can also create health hazards for the neighborhood.

Improperly operated incineration plants cause air pollution and improperly managed and

designed landfills attract all types of insects and rodents that spread disease. Ideally these

sites should be located at a safe distance from all human settlement. Landfill sites should be

well lined and walled to ensure that there is no leakage into nearby ground water sources.

Recycling too carries health risks if proper precautions are not taken. Workers working with

waste containing chemical and metals may experience toxic exposure. Disposal of health

care wastes require special attention since it can create major health hazards, such as

Hepatitis B and C, through wounds caused by discarded syringes. Rag pickers and others,

who are involved in scavenging in the waste dumps for items that can be recycled, may

sustain injuries and come into direct contact with these infectious items.

OCCUPATIONAL HAZARDS ASSOCIATED WITH WASTE HANDLING

INFECTIONS

Skin and blood infections resulting from direct contact with waste and from infected

wounds. Eye and respiratory infections resulting from exposure to infected dust, especially

during landfill operations.

Different diseases that result from the bites if animals feeding on the waste. Intestinal

infections that are transmitted by flies feeding on the waste

35

Page 36: Waste Management

WASTE MANAGEMENT

CHRONIC DIDEASES

Incineration operators are at risk of chronic diseases, including cancers resulting from

exposure to dust and hazardous compounds.

ACCIDENTS

Bone and muscle disorders resulting from the handling of heavy containers infecting

wounds resulting from contact with sharp objects.

Poisoning and chemical burns resulting from contact with small amounts of hazardous

chemical waste mixed with general waste.

Burns and other injuries resulting from occupational accidents at waste disposal sites or

from methane gas explosion at landfill sites.

DISEASES

Certain chemicals if released untreated example cyanides, mercury and polychlorinated

biphenyls are highly toxic and exposure can lead to disease or death. Some studies have

detected excesses of cancer in residents exposed to hazardous waste. Many studies have

been carried out in various parts of the world to establish a connection between health and

hazardous waste.

THE ROLE OF PLASTICS

The unhygienic use and disposal of plastics and its effects on human health has become a

matter of concern. Colored plastics are harmful as their pigment contains heavy metals that

are highly toxic. Some of the harmful metals found in plastics are copper, lead, chromium,

cobalt, selenium, and cadmium. In most industrialized countries, color plastics have been

legally banned. In India, the government of Himachal Pradesh has banned the use of plastics

and so has Latah district. Other states should emulate their example.

36

Page 37: Waste Management

WASTE MANAGEMENT

PREVENTION MEASURES

Proper methods of waste disposal have to be undertaken to ensure that it does not affect the

environment around the area or cause health hazards to the people living there.

At the household level proper segregation of waste has to be done and it should be ensured

that all organic matter is kept aside for composting which is undoubtedly the best method

for the correct disposal of this segment of the waste. In fact the organic part of the waste

that is generated decomposes more easily, attracts insects and causes disease. Organic waste

can be composted and then used as a fertilizer.

WASTE PREVENTION TECHNIQUES

In general waste prevention can be achieved either:

By reducing the demand to be met (immaterialisation )

By using less harmful material for meeting the demand ( dematerialization)

Usually a waste prevention techniques is related to a certain process, to a certain product,

service or product service system or to a certain consumption behavior.

Process related waste prevention comprises those techniques which reduce waste arising

during production by – establishing internal cycles for auxiliary materials and production

wastes substituting hazardous materials introducing more efficient technologies.

Product related waste prevention comprises techniques which

Allow a repeated use of products or parts of the product

Extend product life and or make products easier to repair or

Change the design of a product in a way that it contains less material or less harmful

material.

37

Page 38: Waste Management

WASTE MANAGEMENT

Service oriented waste prevention either replaces products by services for meeting

the demand, or complements products with a service system in order to maintain the

products in an efficient way.

Consumption related waste prevention comprise those techniques which effect the

life style or the consumption behavior

WASTE WATER MANAGEMENT

Water is one of the most essential parts for human survival. Human water demand for

Industrial water supply, irrigation and generation of power is ever increasing with

development of civilization. Since the start of the industrial revolution and the fast

expanding agricultural activities water resource began to deteriorate with time. In view of

the wide range of activities affecting the quality and water use. Water quality, in general is

determined by the gases, solutes and suspended mater in the water.

In any case water quality is usually affected, directly or indirectly, by human activities

making it harmful for living plants and animals.

Industrial operations produce a liquid product that almost always must be treated before

being returned to the environment. There are three different groups of waste water to be

considered.

39

Page 40: Waste Management

WASTE MANAGEMENT

CLASSIFICATION OF WASTE WATER

Domestic waste water: These waters are produced by the mere acts of living such as using

the bathroom, doing laundry, or washing the dishes. These wastes are normally handled by

the sanitation department, which eliminates pathogens before disposal.

Process waste waters: These waters are produced by some industrial processes and include

the undesired liquid product of any unit operation. The major concern with these wastes is

the reactions that may occur with the environment being either direct or indirect. Some may

rob oxygen from the environment , while others may be toxic

Cooling waste water: These waters are produced as a result of some sort of heat exchanger

where heat is removed from the product. Waters can be used once or recycled. Recycling

creates the necessity for periodic cleaning, where at least some may be released into the

environment. This type of waste must be monitored and often treated and is also a major

factor in thermal pollution of water sources.

WASTE MANAGEMENT

WATER CONSERVATION

Our ancient religious texts and epics give a good insight into the water storage and

conservation systems that prevailed in those days. Over the years rising populations,

growing industrialization and expanding agriculture have pushed up the demand for water.

Efforts have been made to collect water by building dams and reservoirs and digging wells;

some countries have also tried to recycle and desalinate (remove salts) water. Water

conservation has become the need of the day. The idea of ground water recharging by

harvesting rainwater is gaining importance in many cities.

In the forests, water seeps gently into the ground as vegetation breaks the fall. His

groundwater in turn feeds wells, lakes and rivers. Protecting forests means protecting water

catchments. In accident India, people believed that forests were the mothers of rivers and

worshipped the sources of these water bodies.

Some ancient Indian methods of water conservation

The Indus Valley Civilization that flourished along the banks of the river Indus and other

parts of western and northern India about 5000 years ago had one of the most sophisticated

urban water supply and sewage systems in the world. The fact that the people were well

acquainted with hygiene can be seen from the covered drains running beneath the streets of

the ruins at both Mohenjo-Daro and Harappa. Another very good example is the well-

planned city of Dholavira, on Khadir Bet, a low plateau in the Rann in Gujarat. One of the

oldest water harvesting systems is found about 130 km from Pune along Naneghat in the

Western Ghats. A large number of tanks were cut in the rocks to provide drinking water to

tradesmen who used to travel along this ancient trade route. Each fort in the area had its own

water harvesting and storage system in the form of rock-cut cisterns, ponds, tanks and well

that are still in use today. A large number of forts like Raigad had tanks that supplied water.

In ancient times, houses in parts of western Rajasthan were built so that each had a rooftop

water harvesting system. Rainwater from these rooftops was directed into underground

tanks. This system can be seen even today in all the forts, palaces and houses of the region.

41

WASTE MANAGEMENT

Underground baked earthen pipes and tunnels to maintain the flow of water and to transport

it to distant places, are still functional at Burhanpur in Madhya Pradesh, Golkunda and

Bijapur in Karnataka, and Aurangabad in Maharashtra. The various methods of water

conservation are:

Rainwater harvesting

Agriculture

Reducing water demand.

42

Page 43: Waste Management

WASTE MANAGEMENT

PREVENTION AND CONTROL OF WATER WASTE

Water pollution is contributed due to industrial effluents and sewage. The time has come to

avert major disaster. Effluent treatment systems have to be incorporated in industry.

Industries, where it is already in existence, need to operate their plans regularly without

looking for savings.

New techniques that need no water are highly beneficial. Some of the wet processes are

replaced by the dry processes.

To minimize the volume of effluents , the waste water that is polluted may be used in

rinsing

Concentrated wastes, low in volume, are mingled with diluted waste for treatment of

disposal. It can be segregated from other streams of diluted wastes, for reduction in

pollution load and diluted wastes after minor treatment is utilized for irrigation.

Small industries cannot afford treatment plants as they frequently discharge their effluents,

near agricultural lands and on roads. It can be avoided by setting up a common effluent

treatment plant where industries are located.

Waste can be converted into wealth. For instance, in our country distilleries can set up

biogas plants which are fed by their effluents resulting in reduction in fuel cost and decrease

in effluent’s strength.

The sludge obtained is a problem. The sludge from pulp and paper industry may be used for

manufacturing boards used in packing or in preparation of artificial wooden panels while

those from the electroplating industry may form water proofing compounds.

Recovery of chemicals and metals is practiced in most industries. The reclaimed waste

water can be reused for industrial processes such as boiler, feeding, cooling which will help

cut down the fresh water needs. And paper mills, sugar industries and distilleries that let out

more effluents can be used for irrigation or as fertilizers after proper treatment, without

affecting ground water.

WASTE MANAGEMENT

WASTE MANGEMENT IN INDIA

There is no Indian policy document, which remains examines waste as part of a cycle of

production – consumption – recovery or perceives the issue of waste through a prism of

overall sustainability. In fact, interventions have been fragmented and are often

contradictory. The new Municipal Rules 2000, which came into effect from January

2004, fails even to mange waste in a cyclic process. Waste management still is a linear

system of collection and disposal, creating health and environmental hazards.

Urban India is likely to face a massive waste disposal problem in the coming years. Till

now, the problem of waste has been as one of cleaning and disposing as rubbish. But a

closer look at the current and future scenario reveals that waste needs to be treated

holistically, recognizing its natural resource roots as well as health impacts. Waste can be

wealth, which has tremendous potential not only for generating livelihoods for the urban

poor but can also enrich the earth through composting and recycling rather than spreading

pollution as has been the case. Increasing urban migration and a high density of

population will make waste management a difficult issue to handle in the near future, if a

new paradigm for approaching it is not created.

Developing countries, such as India, are undergoing a massive migration of their

population from rural to urban centers. New consumption patterns and social linkages are

emerging. India will have more than 40% that is 400 million people clustered in cities

44

Page 45: Waste Management

WASTE MANAGEMENT

over the next thirty years (UN 1995). Modern urban living brings on the problems of

waste, which increases in quantity, and changes in composition with each passing day.

There is, however, an adequate understanding of the problem, both of infrastructure

requirements as well as its social dimensions. Urban planners municipal agencies,

environmental regulators, labor groups, citizens group and non-governmental

organizations need to develop a variety of response which are rooted in local dynamics

rather than borrow non-contextual solutions from elsewhere.

There have been a variety of policy responses to the problem of urban solid waste in India,

especially over the past few years, yet sustainable either of organic or inorganic waste

remains an untapped and unattended area. All policy documents as well as legislation

dealing with urban solid waste mention or acknowledge recycling as one of the ways of

diverting waste, but they do so in a piece meal manner and do not address the framework

needed to enable this to happen. Critical issues such as industry responsibility, a critical

paradigm to enable sustainable recycling and to catalyze waste reduction through, say better

packing, has not been touched upon.

This new paradigm should include a cradle-to-grave approach with responsibility being

shared by many stakeholders, including product manufacturers, consumers and

communities, the recycling industry, trade, municipalities and the urban poor.

WASTE MANAGEMENT

HOW TO CONTRIBUTE EVERYDAY

All of us in our daily lives contribute our bit to this change in the climate. Give these points

a good, serious thought;

Electricity is the main source of power in urban areas. All our gadgets run on electricity

generated mainly from thermal power plants. These thermal power plants run on fossil fuels

(mostly coal) and are responsible for the emission of huge amounts of greenhouse gases and

other pollutants.

Cars, buses and trucks are the principal ways by which goods and people are transported in

most of our cities. These are run mainly on petrol or diesel both fossil fuels. We generate

large quantities of waste in the form of plastics that remain in the environment for many

years and cause damage.

We use huge quantity of paper in our work at schools and in offices. Have we ever thought

about the number of trees that we use in a day??

Timber is used in large quantities for construction of houses, which means that large areas

of forest have to be cut down.

A growing population has meant more and more mouths to feed. Because the land area

available for agriculture is limited (and in fact, is actually shrinking as a result of ecological

degradation), high-yielding varieties of crop are being grown to increase the agriculture

output from a given area of land. However, such high – yielding varieties of crops require

large quantities of fertilizers; and more fertilizer means more emissions of nitrous oxide.

46

EFFORTS TOWARDS WASTE MANAGEMENT

The World Bank Group currently has about 120 active projects with solid waste

management components. There are about 85 projects under supervision with $3.5 billion in

loan/grant commitments, of which about 85% is designated for ‘urban environment’

activities. Solid waste management is the main component in more than half of these

projects. At least 20 projects with large solid waste components are now under preparation

within the $4.5 billion (minimum) urban environment pipeline. An estimated 20 additional

projects are in the pipeline.

A large number of NGOs are working in the field of solid waste management such as clean

Ahmadabad Abhiyan in Ahmadabad, waste wise in Bangalore, Mumbai environmental

action group in Mumbai, and Vatavaran and Srishti in Delhi. They are all successfully

creating awareness among the citizens about their rights and responsibilities towards solid

waste and the cleanliness of their city. These organizations promote environmental

education and awareness in schools and involve communities in the management of solid

waste.

EDUCATION AND AWARENESS

Page 49: Waste Management

WASTE MANAGEMENT

Education and awareness in the area of waste and waste management is increasingly

important from global perspective of resource management. The Tallories declaration is a

declaration for sustainability concerned about the unprecedented scale and speed of

environmental pollution and degradation, and the depletion of natural resources. Local ,

regional and global air pollution; accumulation and distribution of toxic wastes; destruction

and depletion of forests, soil and water; depletion of the ozone layer and emission of “green

house” gases threaten the survival of humans and thousands of other living species, the

integrity of the earth and its biodiversity, the security of nations and the heritage of future

generations. Several universities have implemented the Tallories Declaration by establishing

environmental management and waste management programs, example the waste

management university project. University and vocational education are promoted by

various organizations, example WAMITAB and Chartered Institution of Wastes

Management. Many supermarkets encourage customers to use their reverse vending

machine to deposit used containers and receive a refund from the recycling fees. Brands that

manufacture such machines include Tomra and Envipco.

CASE STUDY 1

WASTE MANAGEMENT OF THE GRAND CENTRAL, PAREL

(INDIAN TOBACCO CORPORATION)

INTRODUCTION OF INDIAN TOBACCO CORPORATION

ITC was incorporated on August 24, 1910 under the name Imperial Tobacco Company of

India Limited. As the Company's ownership progressively Indianised, the name of the

Company was changed from Imperial Tobacco Company of India Limited to India Tobacco

Company Limited in 1970 and then to I.T.C. Limited in 1974. In recognition of the

Company's multi-business portfolio encompassing a wide range of businesses - Cigarettes &

Tobacco, Hotels, Information Technology, Packaging, Paperboards & Specialty Papers,

Agri-business, Foods, Lifestyle Retailing, Education & Stationery and Personal Care - the

full stops in the Company's name were removed effective September 18, 2001. The

Company now stands rechristened 'ITC Limited'.

Though the first six decades of the Company's existence were primarily devoted to the

growth and consolidation of the Cigarettes and Leaf Tobacco businesses, the Seventies

witnessed the beginnings of a corporate transformation that would usher in momentous

changes in the life of the Company.

ITC's Packaging & Printing Business was set up in 1925 as a strategic backward integration

for ITC's Cigarettes business. It is today India's most sophisticated packaging house.

51

WASTE MANAGEMENT

In 1975 the Company launched its Hotels business with the acquisition of a hotel in Chennai

which was rechristened 'ITC-Welcome group Hotel Chola'. The objective of ITC's entry

into the hotels business was rooted in the concept of creating value for the nation. ITC chose

the hotels business for its potential to earn high levels of foreign exchange, create tourism

infrastructure and generate large scale direct and indirect employment. Since then ITC's

Hotels business has grown to occupy a position of leadership, with over 100 owned and

managed properties spread across India.

52

WASTE MANAGEMENT

PROCEDURE OF WASTE MANAGEMENT

ITC prides itself on being Solid Waste recycling positive - recycling more waste than its

businesses generates. All ITC units/businesses, apart from minimizing waste generation, are

mandated to recycle 100% of waste generated by their operations. Waste recycling provides

solutions for saving natural resources and energy. It also reduces costs and environmental

pollution. Recycling prevents wastes from reaching landfills and creates significant

employment opportunities.

Waste paper is a key input in the manufacture of recycled paperboards. ITC PSPD has

commenced a strategic initiative for wastepaper recycling called "WOW" (Wealth Out of

Waste). This intervention has established an efficient collection and recycling chain -

targeting larger sources of aggregation such as schools, offices and residential colonies.

Apart from contributing to a cleaner environment, WOW is an important source of cost

competitiveness for the industry.

The waste that is generated in the hotel is been classified in to three types:

Food waste.

Water waste.

Oil waste.

Page 54: Waste Management

WASTE MANAGEMENT

FOOD WASTE:

The waste that is collected from the kitchens contributes the food waste. It

consists of salads, vegetable cuttings, food that is ordered and wasted from the customers.

All the waste that is collected from the kitchen is segregated in to degradable and non-

degradable waste.

DEGRADABLE WASTE:

The degradable waste is collected in green bins. As the waste that is

collected is degradable that is it gets decomposed so it is collected in green colored

bins. To manage this degradable waste they have two types of machines i.e.

Organic waste controller.

Two stage shredder.

NON- DEGRADABLE

WASTE

Page 55: Waste Management

WASTE MANAGEMENT

ORGANIC WASTE CONTROLLER:

The organic waste controller is a machine which converts the degradable waste in to a

organic powder that can be used as a manure.

The process of the organic waste controller can be explained as below:

55

Degradable waste collected is put in OWC

Add brown and white powder

Grinding process.

Fine organic powder.

Decomposition of organic powder.

Manure obtained.

Page 56: Waste Management

WASTE MANAGEMENT

The waste that is collected is poured in the organic waste controller then brown

powder that is saw dust and white powder that is vioculum bacteria is added to it.

The saw dust that is added to the waste is used to maintain the dryness of the wet

food waste.

This stuff is grinded and then finally an organic powder is obtained.

This organic powder is poured into crates and is placed in to storages racks. The

crates are arranged in a day wise manner. These crates are moved ahead day by

day.

During this day by day rotation the organic powder is been decomposed. During

this process the growth of bacteria occurs.

There is also an arrangement of a water pipeline which gives water to these crates

in every 15 minutes for 3-4 sec.

When the crates reach the last shelf that is after 7 days the organic manure is

prepared. This manure is used as a fertilizer for growing plants.

They also sell this manure in tones to contractors, vendors and then it is further

been supplied to the builders like Raheja , Rustomjee etc.

Non – degradable waste:

The non- degradable waste collected in yellow bins. As the waste that is collected

is non-degradable it is collected in yellow bins. This waste consists of the

aluminium foils, plastic materials, bottles etc.

56

Page 57: Waste Management

WASTE MANAGEMENT

WATER WASTE:

Waste water comprises of the water from the kitchens, toilets, swimming pools etc.

It is collected at the effluent treatment plant (ETP). This one of the waste water

management plant.

Through ETP process two layers of water are formed.

The lower water level is of bacteria. The upper level is the purified water.

This purified water is used for flushing purposes, irrigation purposes etc.

This water is also used in the cooling tower. This is a part of the air conditioning

system.

They use the entire water for the hotel purpose. They do not give it to the BMC.

OIL WASTE:

Oil waste is generated from the drainage water. This water contains a surface of oil

at the top of it. This oil is collected and then sold it to the vendors for further treatment.

The vendors convert this oil in to a bio diesel fuel. The vendors then sell it to many

hospitals etc. the hospitals that follow waste management buy this bio diesel fuel. They

use this to treat their hospital waste as it cannot be disposed haphazardly. They use this

bio diesel fuel in incerinators to treat the bio medical waste.

WASTE MANAGEMENT

CONCLUSION

Vasundhara or earth is the only planet in our solar system which can support life

so it is very important to save it from various waste hazards.

Thus, waste management is of great concern to mankind as it affects the entire

planet and all its living creatures. Increasing amounts of wastes generated everyday is

becoming a major problem particularly in urban cities around the globe.

With the rapid growth of population, there has been a substantial increase in the

generation of solid waste resulting into the contamination of air, water and land resources.

Human activities create waste, and it is the way these wastes are handled, stored, collected

and disposed of that pose risks to the environment and to public health.

Thus, it is rightly said that God Gives Enough to Satisfy Every Man’s Need but

not
