Closing the loop on waste – and integrating it with other systems – may be more than a noble policy goal. In fact, it may make smart economic sense as well. Waste streams often still contain things of remarkable value – if they are extracted and used in the right way. Landfill mining advocates note that landfills have a higher concentration of aluminum than the metallic ore that is normally used as a raw material. The East Bay Municipal Utility District in California is using food and bio waste to save $3 million per year and generate more than enough electricity to meet its own needs. “Waste to energy” projects are cropping up in Mexico, Canada, Scotland and Norway. And as water rights become an increasingly difficult issue – especially in the American West and South – reusing water from the waste stream is a particularly encouraging prospect.
