There is a challenge as a result of growing environmental consciousness, harsher laws, urban densification, population growth, and the production of new goods. Recycling and reuse of waste, also envisioned as waste reduction, assist to get better management of the solid waste generated. Reducing waste generation and recycling are equally effective measures for lowering greenhouse gas (GHG) emissions. Methane, one of the major GHGes, has been estimated to have a global warming potential 28 times that of carbon dioxide over 100 years. The concentration of methane (CH4)in the atmosphere has risen dramatically over the last few centuries. From 1750 to 2010, the concentration of CH4 in the environment increased from 700 to 1808 parts per billion (ppb). The effective management of municipal solid waste (MSW) and conversion of landfill gases into fuel can control global warming up to a significant level. A well-equipped engineered landfill is one of the options for energy generation. Rapid population growth and urbanization result in a huge generation of MSW. The huge MSW generation can be another source of energy for the expanded demand of the population with time.
