Landfill gas to electricity – Vectren
Vectren Corporation is an energy holding company headquartered in Evansville and has provided gas and/or electricity to more than one million customers in Indiana and Ohio.
Vectren completed a landfill gas-to-electricity project and opened the Blackfoot Clean Energy Facility at the Blackfoot landfill in Pike County in 2009. The goal of the project was to utilize landfill gas from the Blackfoot landfill to generates electricity.
About two-thirds of waste discarded at landfills is generally biodegradable and produces harmful gases called landfill gas as it rots and decomposes. Landfill gas is roughly composed of about 50% methane and 50% carbon dioxide. Methane is one of the greenhouse gases that contributes to global climate change and is 28 to 36 times more effective than carbon dioxide at trapping heart in the atmosphere. But, at the same time, methane is a renewable energy source that can be used for electricity generation.
