ECO-FRIENDLY

TECHNOLOGIES

A PRESENTATION


2/51

MODULE 1WHAT IS ECO-FRIENDLY TECHNOLOGY ?

Eco-friendly technology is the method or application used to produce a safer and unpolluted environment.Eco friendly technology looks to improve intwo major areas:

1. Energy efficiency .2. Reduction of harmful waste.


3/51

WHY ECO-FRIENDLY TECHNOLOGY?

Originally , our earthwas very green &beautiful.But, man s progress invarious fields hascompletely devastated

our environment.Thus , repairing thedamage is mandatory.

ENVIRONMENTAL PROBLEMS FACEDBY THE WORLD

Global WarmingRising Pollution

Abrupt Climatic ChangesWater Crisis

Problem Due To Non-Degradable Waste


5/51

GLOBAL WARMING

Global Warming isdefined as the increaseof the averagetemperature of Earth.The increasing

pollution has lead to

the green house effect which in turn, results inrise in temperature.


6/51

RISING POLLUTION

Due to industrial development, harmful gases like carbon dioxide,sulphur dioxide, carbonmonoxide, CFC s, etc areadded to the atmosphere.

These gases are highl y toxic and can causehazardous effects.


7/51

WATER CRISIS

As of today, more thantwo billion peopleworldwide are facing

water scarcity .If we do not work towards this crisis fast,soon we shall have towitness life without water.


8/51

ABRUPT CLIMATIC CHANGES

The increasing pollutionhas in turn caused various climatic abrupt changes.

As a result, we arewitnessing anincreasing number of droughts, famines,hurricanes.etc.


9/51

PROBLEMS DUE TO NON-DEGRADABLE WASTE

Non-degradable wastesmainly include plastics,

polythenes, rubbers, etc.They keep onaccumulating & addingto the garbage.They pose a threat tothe nutrients in soil.


10/51

AIM S OF USING ECO FRIENDLY TECHNOLOGY

Meeting the needs of society in ways that can continue indefinitely into the futurewithout damaging or depleting natural

resources.Creating products that can be fully reclaimed or re-used.Reducing waste and pollution by changing

patterns of production and consumption.Developing alternatives to technologies that damage health and the environment.

MODULE 2

VARIOUS ECO-FRIENDLY TECHNOLOGIESBEING IMPLEMENTED AT PRESENT

RENEWABLE ENERGY SOURCES ALTERNATIVES TO PETROL AND DIESEL

BAN ON USAGE OF CFC-BASED APPLIANCES


12/51

RENEWABLE ENERGY SOURCES

Hydropower Solar Power

Wind Power BiomassGeothermal Power Nuclear Power


13/51

HYDROPOWER

Various forms:Hydroelectric energy

Ocean thermal energy Tidal power

Dam-less hydro power Osmotic power


14/51

SOLAR POWER

15/51

WIND POWER

Globally, the long-term technical

potential of wind energy is believed tobe five times total current global

energy production,or 40 times current electricity demand.


16/51

BIOMASS

Biomass refers to livingand recently dead biological material that

can be used as fuel or for industrial production.It includes dead trees &branches, yard clippings,

wood chips &biodegradable wastesthat can be burnt as fuel.


17/51

GEOTHERMAL POWER

Geothermal energy is energy obtained by tapping the heat

formed within theearth.It is expensive to

build a power station but operating costs arelow & affordable.


18/51

NUCLEAR POWER

Nuclear power isenergy extracted

from the atomic nuclei via controlled nuclear reactions.Reprocessing can

potentially recover upto 95% of theremaining uraniumand plutonium whichcan be further reused.


19/51

ADVANTAGES OF RENEWABLE SOURCES OF ENERGY

Continuous sources of energy. Actual source cost is zero as sun, wind, tides

etc. are available free of cost.Do not release CO2 and other harmful gases.Cause no polluting emissions.

Contribution to Global Warming is zero.Can be used repeatedly.


20/51

ALTERNATIVES TO PETROL AND DIESEL

Autogas [CNG, LPG,LNG].

Hydrogen. Alcohol fuels.Battery-operated

vehicles.


21/51

B AN ON USAGE OF CFC- B ASED

APPLIANCES

CFCs, HCFCs, halons,etc. (ODS) are used in refrigerators , air

conditioners and inaerosol sprays.They are the maincontributors to the

creation of the largeOZONE HOLE.

ENVIRONMENTAL ENGINEERING


23/51

ENVIRONMENTAL ENGINEERING

Environmental Engineering is the.application of science and engineering.

principles to improve the environment to provide, healthy water, air, and land for human habitation and for other organisms, and to remediate polluted sites.


24/51

ENVIRONMENTAL ENGINEERS

Their work includes :Waste management Toxic Material Control Water Supply

Storm Water Management Solid Waste Disposal Public Health & Safety Land Management Radiation ProtectionIndustrial Hygiene

Air Pollution & Quality

Control

THE FIRST PROJECT

Modernenvironmental engineering first started in London by

JOSEPH BAZALGETTE.He designed the first

Sewage system tocontrol waterbornediseases likeCHOLERA.

NEERI

National Environmental EngineeringResearch Institute.Major projectsunder itsconstructions:-.

1. Kalpasar Project.2. Mumbai Sewage

System.


28/51

KALPASAR PROJECT

Kalpasar means alake that fulfil all the wishes.The project having a

power to fulfill thewater and energy needs of Gujarat

state.Schedule starts from2011 and going tocomplete till 2010.


29/51

ADVANTAGES

Water supply for Industrial use.Irrigation from fresh water reservoir.

Tidal power.Land Reclamation.Road communication.

Fisheries development.

B EING ECO-FRIENDLY IN DAY-TO-DAY

LIFE

Car pooling / using

public transport.Reduction of waste.

Avoid usage of

plastic.Plant trees.Unplug un-used gadgets .


33/51

CARPOOLING OR USING PUBLIC TRANSPORT

Advantages:Saves fuel.Decreases pollution.Combatsrising traffic congestion.In a global

perspective, reducesgreenhouse gasemissions.Cost effective.


34/51

REDUCTION OF WASTE

Things you can do! Maintain things properly. Avoid heavily packaged

products.Reuse things.Pass them on - to

family and friends.Reduce excess paper at home.Reduction of waste.


35/51

AVOID USAGE OF PLASTIC

Plastics accumulate at the rate of 25 milliontones per year.

Say "no" to plastic grocery bags.Think durable not

disposable.Watch what goes intothe storm drains.


36/51

PLANT TREES

Advantages:Trees remove excessamount of carbondioxide & air

pollutants.Improve the quality of air.Biodiversity getsenriched.


37/51

UNPLUG UN-USED GADGETS &

APPLIANCES

40%-75% of energy inhouseholds isconsumed by

electronics that areturned off but

plugged in.You can save all thisenergy just by unplugging.

JUST UNPLUG !
