` Exhaustion of natural resources:Petroleum (40 yr), copper (28 yr)
` Water crisis 1/3 reduction in fresh water supply per capita within 25 yr
` Desertification & global food crisis:` 1/3 of Asian agricultural land desert
` Continued GHG emission: Annual 5-20% decrease in global GDP under the current
economic system

living under absolute poverty
j rapid industrialization and
urbanization* Increasing demands in raw materials
* Increasing energy consumption and
GHG emission
jClimate change
Agricultural productivity decline anddeminishing food security
jIncreasing solid waste
*improper management system, lack
of technologies, limited landfill site

` a concept of being able to continue
growing economic output without acorresponding increase in
environmental impact.Can We Separate
GDP Growth And
Ecological Limits?
jImprovements in production efficiency allow you to make
more with less.
jTheoretically we can increase efficiency and make more
stuff using the same amount of resources and/or generating
the same amount of pollution.

` Relative decoupling refers to a decrease inenvironmental intensityper unit of economic output. This
means the impacts on resources decline relative to GDP,
but they dont decline completely just grow slower than
GDP.
` Absolute decoupling occurs when ecological intensitydeclines in absolute terms, or an overall decrease as
GDP increases.

` Inputs in production (resources and natural
capital) are costs to the producer.
` in a free market economy, producers will push to
reduce costs by increasing theirefficiency.` One example of this is found in the amount of
energy needed to produce each unitof
economic output, which globally has fallen over
the last 50 years.

` Asian economic growth drives world growth
`
Intensities/ratios lower in developing Asia, butlikely to rise with accelerating economic
development, and catching up with the West
` Need for deliberate action to achieve decouplingin Asia

` Aluminium: recycling costs 20% of extraction (from
mining of bauxite)-refining` Biofuel as an alternative energy source to reduce
GHG
* Massive use of agriculture land
biodiversity damage and food shortage
non food-based biofuel is necessary

Worldwide, our resource use has
increased.In the case of cement production it has
doubled; structural metal extraction is
increasing quicker than GDP.

` to seek out a society with a stable population, a
stable economy, and increasing technological
efficiency (as far as we can push it) to decrease
environmental impacts.
` This will make a better world for those living in it.

` The rapid drop in energy costs from historic highs
and a growing recession arent blunting the
chemical industrys efforts to reduce energy
consumption` Feedstock and energy make up about 70% of
costs in the bulk chemical processes and the
monthly energy bills for these companies are still
huge. So any saving will have a very big impact,

` real-time optimization, utilities and design
jReal-time optimization allows operators to continuously maximizemargins, which improves the overall business
j(Netherlands) centralized utility system generates the energy neededfor the sites processes, reduce annual energy bill (Netherlands is acountry where energy is one of the most expensive commodities forchemical producers).
j Samsung Total Aromatic Complex in Daesan, Korea, illustrates thethird point. The scope for energy savings is very much greaterwhen you move from optimization to design.

` capturing energy data from plants to create energy
models that demonstrate the difference between
what plants are doing and what they could be
doing
` This performance assessment serves to identify
possible solutions.

` A self-cleaning filter not only allowed one company to add efficiency
and safety, it also boosted competitiveness.
` Neville has used a variety of different systems for filtration of
impurities from its finished resin products for many years. While filter
bags performed well in removing impurities from resin, they were
costly, required continual changing that interrupted production, was adifficult task for workers and also potentially hazardous.
` Modernizing its resin filtration system enabled Neville Chemical to
make significant productivity gains, reduce waste, and eliminate a
laborious task that was risky to workers' health` A spiral wiper design ensures the filter element is kept continuously
clean, and so maintains optimum efficiency. Because of its self-
cleaning design, cleaning of the filter between batch runs is quick and
easy with minimal disruptions during production changeovers

` honored the ARCH CHEMICALS' BRANDENBURG,KENTUCKY with a Safety Achievement Award, whichwas based on the plants achievement ofzero lostworkday cases involving days away from work in 2002because of workplace injuries or illnesses.
` The plant produces various glycol products, which areused in everything from antifreeze to foods and personalcare products. It is also home to a customer support
laboratory and applications center for Arch WoodCoatings, which makes topcoats, lacquers, stains andother products for fine home and office furniture.
