The biogas plant uses biogas produced by surplus food from hospitals, hotels and restaurants and organic waste from the food industry as fuel for internal combustion engines. The electricity generated is fed into the utility grid, and exhaust from the internal combustion engine is used to create steam. Steam can be used to sterilize waste at high temperatures, To make sterile fertilizer.
