A LAND FILL FULL OF ENERGY

SOLUTIONS JOURNAL - It used to be that the only exports of the Mamak Landfill in Ankara, Turkey were the powerful stench of rotting garbage and the foul liquid runoff that seeped into underground waters. But today, the landfill has cleaned up its act and is cranking out approximately 340 GWh of electricity per year that can be plugged into Turkey's national grid. . .

The ultimate goal is a "zero waste" landfill that has virtually no negative environmental effects - lofty aspirations for trash. For the twenty million tons of waste already stored at the site, a land fill gas extraction and utilization system is now used to harness and compress the methane gas released by decomposing waste and convert it into electricity. And as for the 3,500 tons of 'fresh' garbage entering the landfill each day, a biodigester will use the anaerobic digestion of bacteria to convert organic waste into compost and much-needed green power. . . .
