Explanation / Answer

1.Bioreactor landfills reduce the amount and costs involved in management of leachate, to increase the rate of production of methane for commercial purposes and reduce the amount of land required for land-fills.

There are three types of bioreactor: aerobic, anaerobic and a hybrid (using both aerobic and anaerobic method). All of these mechanisms involve the reintroduction of collected leachate added with water to maintain moisture levels in the landfill.

Bioreactor landfills are most efficient and effective where the refuse has high organic content and high exposed specific surface area.
