METHOD AND DEVICE FOR THE RECYCLING AND EXPLOITATION OF BIODEGRADABLE DOMESTIC WASTE PRODUCED IN THE DWELLINGS OF A COMMUNITY, BY MEANS OF BIOGAS-PRODUCTION PLANTS, IN ORDER TO PRODUCE ELECTRICITY AND FERTILIZER AND TO HEAT WATER

摘要

The invention relates to a method and device for the recycling and exploitation of biodegradable domestic waste produced in the dwellings of a community, by means of prefabricated biogas-production plants, in order to produce electricity and fertilizer and to heat water. The waste is ground in a grinder provided in the kitchen sinks and is conveyed, by means of a network separate from the sewage network, to a biogas-production plant formed by digesters, where biogas is produced by means of anaerobic digestion. The invention includes safety and control mechanisms, a biogas consumer, a biogas reservoir and a place where the inert material resulting from biodigestion can be deposited. This material can be used as fertilizer. Optionally, the waste can originate from gardens. The biogas is consumed in the consumer and used to produce electrical power, mechanical power or to heat water. The electrical power generated may be fed into the grid.
