Procedure for reducing solid waste mass containing a fermentable fraction, comprises sorting and/or sifting of solid waste to recover enriched fraction in fermentable elements, and crushing and/or sampling of solid waste

摘要

The procedure for reducing solid waste mass containing a fermentable fraction, intended to be hidden in a storage center, comprises sorting (1) and/or sifting (2) of the solid waste to recover enriched fraction in fermentable elements, crushing and/or sampling of solid waste, and biological degrading (3) of the fermentable fraction elements by micromycetes carried out at 30-50[deg]C for 15-20 days at a humidity rate of 35-40%. The solid waste is household-, industrial- and/or green waste. The micromycetes are injected with the solid waste mass (0.5-1%) to be treated. The procedure for reducing solid waste mass containing a fermentable fraction, intended to be hidden in a storage center, comprises sorting (1) and/or sifting (2) of the solid waste to recover enriched fraction in fermentable elements, crushing and/or sampling of solid waste, and biological degrading (3) of the fermentable fraction elements by micromycetes carried out at 30-50[deg]C for 15-20 days at a humidity rate of 35-40%. The solid waste is household-, industrial- and/or green waste. The micromycetes are injected with the solid waste mass (0.5-1%) to be treated. The biological degradation is carried out by an injection of air to a flow of solid waste (10-15 Nm3/h/m3). A sludge purification station such as industrial or municipal wastes are added to the solid waste at the time of the biodegradation of the fermentable elements of solid waste. The biological degradation of the fermentable waste elements are treated using a pozzolana biofilter containing micromycetes fixed on a solid support. Independent claims are included for: (1) a treatment of solid waste; and (2) an installation for reducing solid waste mass containing a fermentable fraction.
