A Review paper on Comparative Study for Management of Landfill By-Products

Abstract

Sanitary landfills are the most popular method of ultimate disposal of solid waste throughout the world. It is a land disposal site employing an engineered method of disposing of solid waste on land by minimizing volume and applying compaction cover material at the end of each day. Most of the global municipal solid waste is dumped in non regulated landfills which generate by-products like methane and leachate. The generated methane has high global warming potential while leachate is the most polluted liquid generated in a landfill which can pollute ground water. This paper focuses on comparative study of characteristics, generation process and various controlling techniques for reducing the concentration of methane and leachate. Both of which can also be used for generation of clean and renewable energy. An alternate eco-friendly energy fuel source “Microbial Fuel Cell (M.F.C)” which converts organic   matter into electricity with the help of bacteria present in waste water while simultaneously treating the waste water will also be overviewed in this paper.
