The nytimes.com blog Green Inc. reports that:
Enerkem, a green energy company based in Quebec, has developed an alternative approach to mining the carbon out of non-recyclable plastics, construction waste and other materials found in the municipal waste stream.
The company says it has pioneered a gasification technology that processes waste into a synthetic gas that can be converted into liquid fuels and biochemicals, and it has entered a 25-year deal with the City of Edmonton to purchase the trash left over after glass, metals, paper and recyclable plastics have been removed.
