With the thousands of pounds of wasted produce and other food items in landfills and composts, there is a movement towards methane capture as a viable source of income. With the burning of methane, heat generated can be converted to electrical power. When the bacteria used in composting convert the organic materials to fertilizer through anaerobic digestion, methane is created. Using a methane bio-digester, methane is captured as this process occurs. As methane is a gas that can be used to heat and power, the naturally occurring methane from the decomposition of materials will simply serve as an additional stream of revenue when collected. Therefore composting implemented on a larger scale could be used as a lucrative energy source. As an example, the Johnston landfill has begun their own methane capture program.
