ECONOMIC COSTS • Natural Gas Burner for ROCK-TENN • = $ 11.2 million • RDF/biomass Burner • $300 - $500 million ?????
OUTLINE • 1. Waste Management & the Big Picture • 2. The arguments against incineration • 3. Incineration air emissions • 4. Incineration & dioxins • 5. The alternative to landfills and incinerators
We are living on this planet as if we had another one to go to We cannot run a throwaway society on a finite planet We are robbing our own children and grandchildren This is colonialism in time! Landfills BURY the evidence IncineratorsBURNthe evidence We need to face the real problem…
Not only is over-consumption giving us a local waste crisis but also…
The Global Crisis:Since the Industrial Revolution we have imposed a linear society on a planet that functions in circles

Waste Management Options and Climate Change. AEA 2002 • “Overall, source segregation of MSW, followed by recycling (for paper, metals, textiles and plastics) and composting/AD (for putrescible wastes) gives the lowest net flux of greenhouse gases compared to other forms of treatment of bulk MSW”

Incineration is a waste of energy! • 3-4 times more energy can be saved by a combination of reuse, recycling and composting compared to incineration • Contact: Dr. Jeffrey Morris, jeff.morris@zerowaste.com

2. Arguments against incinerators • They generate a toxic ash which is poorly handled • They generate toxic air emissions, which are poorly monitored • They are extremely expensive and a poor investment for our children. • They are very unpopular with the public and pushed into communities undemocratically • Incineration is not sustainable • There are better alternatives which are
Incineration is extremely unpopular • In the US over 300 incinerator proposals defeated since 1985 • US has not permitted a new trash incinerator since 1995.
Incineration is a poor investment • Most of the money spent on incinerators goes into complicated machinery and leaves the community, whereas • The money spent on the alternatives goes into jobs and stays in the community.
Think of an incinerator as three boxes 1. The Furnace which Converts 100’s of Tons of trash into Trillions of tiny particles and gases.

Ash management • In Germany & Switzerland fly ash put into nylon bags and placed in salt mines • In Japan some incinerators vitrify the ash • In the Netherlands they put the fly ash into asphalt and the bottom ash into road bed • In Denmark… • They send all the ash to Norway • In the US the EPA allows the bottom ash and fly ash to be mixed together before testing
