Abstract: A method of sequestering carbon captured from the atmosphere by plants (biomass) waste material includes segregating incoming waste material that includes biomass into high-moisture incoming waste material and low-moisture incoming waste material. The low-moisture incoming waste material is that which has a moisture content less than or equal to the moisture content threshold, for example, paper, cardboard, and sawdust. The low-moisture incoming waste material is stored in a dry containment area, thereby emissions of carbon dioxide or methane from the low-moisture incoming waste material is reduced as moisture is required by such material to decompose.

Abstract: The present invention is an anaerobic reactor and preferably a vertically oriented plug flow anaerobic reactor for producing methane from various organic materials. The organic materials preferably have a high organic content. The reactor includes cutting members for cutting bridged or agglomerated material within the reactor. The present invention also includes a process for producing methane from an organic feed stock by continuously charging an organic material into the top portion of a vertically oriented vessel and rotating one or more cutting members at a sufficiently slow rate so that the cutting members cut through bridged or agglomerated material but do not substantially mix contents within the reactor, anaerobically digesting the organic material under mesophilic or thermophilic conditions to produce methane while allowing the organic material to propagate downward through the vessel in a plug flow-like manner and collecting methane gas produced from the anaerobic digestion of the organic material.
