Board system for assembly of walls and base for composting

摘要

The board system for producing a plate body with base and walls to contain loose material (esp. for composting, aeration or dewatering, or treating gasses by a filter material placed on the board body) has a fluid-permeable lower plate (40, 41, 42) for placing on a flat foundation, and an upper carrier plate (30, 31) with openings. Spacers (20) create a gap between the lower and upper plates. The gap contains a space and/or a liq.- and/or gas- supply system. The gap has at least one fluid outlet and/or gas inlet. A wall element (1) has a push joint (15) to the base plate and the carrier plate. Pref. the wall element is of extruded plastics.
