EPC says:
Anaerobic Digestion helps to mitigate global warming in two ways:
- First, by capturing biogas, AD systems reduce emissions of methane, a greenhouse gas 21 times more potent than carbon dioxide.
- Second, AD produces consistent and dependable amounts of renewable fuel that offset the need for fossil fuels such as coal, oil and natural gas.
