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.
How much biogas can I get out of my waste? The amount of biogas you can extract from your organic waste depends on the waste itself and the design of the digester system. Some digesters can yield 20 m 3 of biogas per tonne of waste while others can yield as much as 800 m 3 per tonne.
