This invention is a permeable cover layer for the control of methane, volatile organic compounds (VOCs) and/or odor causing compounds. It is designed to control emissions from area sources such as: composting operations (household and animal wastes), anaerobic digesters, organic sludge drying operations, waste storage operations, contaminated soils storage or treatment operations. The control is achieved through a combination of activated carbon adsorption and passive (i.e. no active ventilation) biofiltration. |

| Claim: |
1. A permeable biofiltering cover layer formed by spreading a composition consisting of: (a) a bulking material comprising a fibrous material such as mulch, (b) a polymeric binder, (c) a bacterial culture, and (d) other additives, including adsorbents, dyes, and nutrients, the composition when mixed with an aqueous carrier forming a sprayable aqueous slurry suitable for providing a cover layer over a selected material to control emissions of volatile organic compounds (VOCs) and to provide physical protection against erosion. |
