` 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

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,


17/27

` 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.
