Type      HOFGAS®-Ready/C 2000
Performance      2,000 Nm³/h, 10,000 kW
Location      Zambiza (EC)

The landfill is located near Quito, the capital of Ecuador. Since 1979 five million tonnes of domestic refuse has been deposited. After successful degassing trials, it was established that the refuse site has ideal conditions for emission trading. As part of the Kyoto Protocol, Green Gas Germany submitted the PDD (Project Design Document) for acknowledgement and registration.

The Zámbiza Project is bringing a host of positive outcomes for the Quito region. Explosions of methane gas or fires at the refuse site and the environment are prevented, as are harmful effects on health on the local residents from gas emissions, where these were earlier allowed to escape unrestrained. At the same time, technology and know-how are being transferred to the region through foreign investment capital.
