Abstract: Methods of processing municipal solid wastes (MSW) are provided whereby concurrent enzymatic hydrolysis and microbial fermentation of wastes results in liquefaction of biodegradable components as well as accumulation of microbial metabolites. Liquefied biodegradable components are then separated from nondegradable solids to produce a bioliquid characterized in comprising a large percentage of dissolved solids of which a large fraction comprises some combination of acetate, ethanol, butyrate, lactate, formate or propionate. This bioliquid is, itself, a novel biomethane substrate composition, which permits very rapid conversion to biomethane. Methods of biomethane production are further provided using this bioliquid and using other biomethane substrate compositions produced by concurrent enzymatic hydrolysis and microbial fermentation of organic materials.

Abstract: The invention provides a method of processing MSW comprising the steps of—providing a stream of unsorted MSW to a microbial fermentation reactor in which the MSW is fermented with agitation at a non-water content of between 10 and 50% by weight and at a temperature of between 35 and 75 degrees for a period of between 1 and 72 hours under conditions sufficient to maintain a live lactic acid bacteria concentration of at least 10,000,000,000 CFU/L, and—removing a stream of fermented unsorted MSW from the reactor and subjecting it to a separation step whereby non-degradable solids are removed to provide a slurry of biodegradable components. Further, a slurry of bio-degradable components prepared according to said method is provided.
