2. Biogas (Anaerobic Digestion)Good returns where waste processingCapital costs highWin Win Win: Renewable Energy, plus low carbonfertiliser and soil conditioner, reduced smells, betterfertiliser value, better nutrient controlReduces Methane (23 times as warming as CO2)Great transport fuel: zero GHG and no particulates!Choose nature of operation - Inputs from ownresources or import waste (and pasteurise) 3.
