Opis

Aimed at regulators, designers, landfill owners and operators, this work includes information that supports the utility of landfill bioreactors. As well as providing design and operating criteria essential for the application of this technology, the book covers the history and background of landfill technology, research studies of actual bioreactor landfills, expected leachate and gas yields, specific design criteria, operation guidelines, and reuse of landfill sites to avoid having to establish new ones.
