Covered Aerated Static Pile Composting (CASP)
Micropore compost covers are specifically designed for the aerated static pile (ASP) composting technology having the right porosity (7-12 cfm/yd2 average) to closely match the oxygen demand characteristics of the organic feedstock material. The Stedair® Compost Covers also maintain an optimum environment in the pile by controlling temperature and moisture during the active composting phase.
The Stedair® Compost Cover is comprised of a trilaminate polyester fabric on each side of the ePTFE membrane. The covers can be made up in any dimension depending on the volume of the feedstock material and length of time in the active composting phase. The Stedair® MOR ePTFE Micropore Compost Cover has the highest tensile strength, longest UV protection (UV 5000) and best warranty in the industry.
