-chapter 17: green chemistry: practical examples of green chemistry to illustrate its relevance to environmental chemistry
-CCA, anti-corrosion coatings, alternative pesticides, plastic processing, plastics to fuels, and plastics from carpet (closed loop processing)
-additional case studies in thematic areas of environmental chemistry: green chemistry and solvent free reactions, energy

what is the conventional method for cleaning clothes?
what is the green chemistry method for cleaning clothes?
what is computer chip cleaning?
what is the closed-loop SCORR process?
what is the graph of historic industrial ecology?
what is industrial ecology?
how expensive is green chemistry?
what is the graph of the major components of an industrial ecosystem?
what are the five major components of an industrial ecosystem?
- a primary materials producer
- a source or sources of energy
- a materials processing and manufacturing sector
- a waste processing sector
- a consumer sector
what are the two different streams of recycled materials?
- process recycle streams consisting of materials recycled in the manufacturing operation itself
-relatively easy - external recycle streams of materials recycled from other manufacturers or from postconsumer products
-more difficult because of diffuse distribution of materials
what is industrial metabolism?
materials flow and recycling in an industrial ecosystem
the amount of waste and energy consumed generally decreases in going through the industrial ecology cycle from virgin raw material to final consumer product
what is the kalundborg industrial ecosystem?
what is the consideration of environmental impacts in industrial ecology?
what is the graph of the ideal industrial ecosystem?
what is an example of plastics recycling in closed loop processes?
carpet production
what is the disposal of used carpeting?
what was the award winner of the presidential green chemistry award in 2003?
closed loop carpet recycling
what are the advantages of the EcoWorx system?
what is product stewardship?
-vendor may retain ownership, such as in the case with leased photocopy machines
-deposit may be charged that is refunded when the product is returned for recycling
-example: resource extraction analogy
what is high-level and low-level recycling?
what is the life cycle assessment?
what is the example of LCA automobile production?
