I believe code requires a dedicated 20-amp circuit for the refrigerator. However, a 20-amp receptacle is not required unless it's the only one in the circuit. Since a duplex receptacle counts as two, a 15-amp receptacle is OK. 08-20-07, 08:47 AM #3.
biogas plant. Biogas means a gas produced by the anaerobic digestion or fermentation of organic matter. The organic matter can be manure, sewage sludge, municipal solid waste, biodegradable waste or any other biodegradable feedstock. Biogas is mainly methane and carbon dioxide. Depending on where it is produced, biogas is also called: swamp gas; marsh gas; landfill gas; digester gas; Biogas can be used as a vehicle fuel or for generating electricity. It can also be burned directly for cooking, heating, lighting, process heat and absorption refrigeration.
Biogas can provide a clean, easily controlled source of renewable energy from organic waste materials, replacing fossil fuels with a sustainable carbon neutral fuel option. When biogas is processed to become biomethane, it becomes a source of natural gas.andfill gas is biogas produced by organic waste decomposing under anaerobic conditions in a landfill. The waste is covered and compressed mechanically by the weight of the material that is deposited from above. This material prevents oxygen from accessing the waste, and anaerobic microbes thrive.
