<p>Structured layer (13) of particles sized 25-80 mm is applied on top of aerobic rick-type rotting arrangement, and covered with cover layer (12) to create biological filter layer. Residual waste (9) is first homogenized, reduced in size and soaked and placed in rick with chimney (3) to produce draught. The structured layer consists of screening residues produced in compost plants. The residual waste is deposited on air-permeable material such as wood pallets, through which slotted tubes extend. Air is drawn in through the slotted tubes, through the waste and into the chimney. The structured layer and the cover layer are each 15 cm thick. The passage for the slotted tube is formed by placing one pallet over a gap between two other pallets. The slotted tubes are PVC pipes. Three to six, preferably four, pallets are juxtaposed across the direction of the slotted tubes.</p> |
