WtE- A solution for Climate change

Waste to Energy (WtE) is a process that converts municipal solid waste (MSW) into renewable electricity in a controlled procedure that reduces the volume of MSW to 10% of its original size. The heat generated from the combustion chambers heats up water that is then turned to steam and sent through a turbine that continuously generates electricity.

Landfill gas collection is used at some landfills part of the time, but only a fraction of the landfill gas is actually captured. The Earth Engineering Center at Columbia University estimates that only about 50% of landfill methane is captured over the life of the landfill (including landfills with no methane collection systems) and the rest is vented into the atmosphere.Furthermore, no methane is captured during the initial years of a landfill’s operation and after closure. This methane escapes directly into the atmosphere.

Landfills have the potential to create long-term problems including methane emissions, ground water contamination from landfill leachate and rendering land unsuitable for reuse.

Capturing and then converting methane is a very inefficient way to produce energy. As an average, converting landfill methane to energy provides less than 4% of the energy that is generated from the same amount of waste processed in a WtE facility.
