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.
What is Biomethane. Biomethane is a naturally occurring gas which is produced by the so-called anaerobic digestion of organic matter such as dead animal and plant material, manure, sewage, organic waste, etc.ethane is about 20 times more potent greenhouse gas than carbon dioxide if released into the atmosphere. Furthermore, its use for power generation produces heat and emits carbon dioxide and some other gases but despite that biomethane has a number of environmental benefits which make it a green source of energy.
