Waste
ReduceReuse

Best Option:

Low waste approach...Preventing pollution

A form of waste reduction

View as potential resources to r3 or as harmful and not to use in the first place

Refillable bottles: Glass, pet plastic (89% in '64; 7% in '95---- decreased # of jobs)
Order of priorities is different since full
costs not included in market price

Denmark, Equador, Finland, Germany:

Reduce, Refund, Refill

Saves e/virgin materials, decreases extracting/processing/cost, liability (i.e. 3m's 3p program) Reusable lunch boxes, plastic bread bags, cloth bags for groceries
Decrease: consumption, design, redesign, hazardous products. make to last, green, decrease, trash taxes. 95% diapers (disposable) discarded to landfills (wash, hang dry?)
  Tires: Retread, used to produce electricity

 
Waste
RecyclingIncinerate/Bury
Biodegradable ~35% by weight of municipal solid waste output Bioremediation/Phytoremediation to detoxify (Denmark)

Large-scale composting:

Enclose and filter air inside, isolate sites or near landfills, closed metal container (Dutch Tunnel)

U.S. vs. Japan with incineration:

U.S. = does not work;
Japan = works

Types:
Primary = Decrease virgin materials
By 20-90%;

Secondary = decrease by 25% at the most

~60% Solid waste by weight in landfills.

Municipal solid waste:
1995 = 24%

16 states by 2002 = decrease by 50% 60-80 recycling/composting possible

~1/5 of all Superfund sites were former landfills
Recycling increases jobs, makes sense economically with full cost accounting, decreases virgin materials/throughout/pollution
