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 be made at home or at a business from food waste, yard and grass trimmings, and some organic solid wastes. However, efficient use of biogas is more readily accomplished at larger scales. A typical home might cook for an hour per day on biogas from home waste sources.iogas is principally a mixture of methane (CH 4) and carbon dioxide (CO 2) along with other trace gases. Biogas can be collected from landfills, covered lagoons, or enclosed tanks called anaerobic digesters.
