Brief article in MIT Tech Review on strides made in gasification processes (turning garbage/ waste into fuel & electricity), in this case *without* using incineration. That last bit is key, since incineration is a huge polluter.

And the new method(s) aren't commercially viable yet:
QUOTE
There may still be hurdles to commercial success. Childress notes that waste gasification may still face problems with local regulations. And companies using similar technologies have failed in the past. Nevertheless, some waste-gasification companies are reporting initial success. For example, Enerkem, based in Alberta, Edmonton, has opened a commercial facility to convert used utility poles into methanol and ethanol. It has signed an agreement with the city of Edmonton to process 100,000 tons of municipal solid waste a year for 25 years, although that's still a relatively small amount compared with other options for disposing of waste.

Discussion of Montreal's Canadian Centre for Architecture's publication "Actions: What You Can Do With The City" (Mirko Zardini and Giovanna Borasi): 98 examples of "techniques, events, ideas and strategies aimed at making cities more sustainable, humane, efficient, livable and, not least, fun." I was especially intrigued by what Hume describes as "Actions"' subtext, *waste* - see article.

"Our whole economy has become a waste economy," writes Zardini quoting Hannah Arendt, "in which things must be almost as quickly devoured and discarded as they have appeared in the world, if the process itself is not to come to a sudden catastrophic end."

QUOTE
"Whether you're talking about money, goods or even space, these days "waste" has become a bit of a dirty word. Monday, consumers are looking for positive ways to avoid it. They're beautifying unused or neglected public spaces with guerilla gardening; they're sharing their pantry's overstock and garden surplus by food swapping, and they're taking advantage of bountiful harvests found on public and private property with voluntary harvesting. With waste top of mind, the latest waste elimination challenge focuses on the garden.
