Abstract (en)
[origin: WO2005085156A2] The present invention relates to a method of composting a biomass. The method comprises feeding an amount of sludge finto a mixer, feeding an amount of sand into the mixer, feeding an amount of green waste into the mixer, mixing the sludge, sand and green waste to form at least part of a biomass, and composting the biomass. It is preferred that the percentages by weight of the amounts of sludge, sand and green waste in the biomass is within predetermined ranges. It is furthermore preferred that the amounts of sludge, sand and green waste and the content of water in the sludge, sand and green waste are selected so as to obtain a biomass having a water content in the range of 40-65% by weight. The invention further relates to a composting system, which comprises a container for biomass and/or organic waste having outer sidewalls and a bottom wall, which this container has an inner perforated bottom floor being arranged above the bottom wall to form a bottom cavity between the bottom wall and the bottom floor. In a first embodiment of the system the container may further have at least one inner beam being arranged between the outer sidewalls and at a height above the inner bottom floor. The container may further have at least two tilted or angled inner sidewall parts with each of the two outer sidewall parts having at least one of said tilted sidewall parts being arranged along the inside. In a second embodiment of the system, the container further has inner perforated sidewalls arranged along at least part of the outer sidewalls to form side cavities between the outer sidewalls and the corresponding inner sidewall, with openings provided between the bottom cavity and the side cavities to thereby allow a flow of air between these cavities.
