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 bio-degradable components. Further, a slurry of bio-degradable components prepared according to said method is provided.
