db technologies BV designed a plant to sort and prepare municipal waste to extract recyclables, create refuge derived fuel and prepare biological waste for digestion for the city Ventspils in Latvia. The incoming municipal waste is separated by a press extruder into a wet organic fraction and dry non-organic fraction. Because of the very high pressure used in this process the organic fraction is prepared for fermentation to create biogas. The dry fraction is disposed of minerals and metals after which refuge derived fuel or recyclables remain. The plant was delivered in September 2012.
