Patent ID: 8691093

Claim:
An anaerobic waste treatment apparatus, comprising: a container; and a plurality of bio-film media comprised of a plurality of objects movable relative to one another within said container and forming at least a portion of a torus-like shape, said objects including one or more attachment surfaces configured to support anaerobic bacteria growth that facilitates degradation of waste material introduced into said container, and one or more voids for accumulating the waste material as the waste material pass through the bio-film media to further degrade the waste material, said bio-film media being initially dispersed within said container in a random arrangement, wherein one or more air pockets are formed in random locations between said objects to trap gas produced by the degradation of the waste material such that over time a buildup of the produced gas within said one or more air pockets moves said bio-film media from said random arrangement into a loosely organized arrangement, wherein one or more through paths are formed between said objects to release the produced gas from said one or more air pockets such that the produced gas can be collected and removed from said container.
