Abstract: The invention provides an assemble-on-site system for collecting biogas from digesting sewage. The system comprises a biogas deflection assembly configured and sized to fit a primary treatment unit; and a collection interface assembly operatively associated with the biogas deflection assembly and configured for connection to a biogas capture or collection system. When installed in the primary treatment unit, the biogas deflection assembly is substantially submerged and provides for the deflection of biogas to point(s) of biogas collection in the collection interface assembly. Also provided are components of the system and kits comprising one or more of the system components and assembly instructions.

Abstract: A biogas capture and/or collection system is provided and comprises one or more biogas capture and/or collection units (BCCU) that capture and/or collect biogas generated in one or more biogas generating chambers (BGC). The BCCUs maybe tubular conduits operatively linked to the BGCs or canisters removably linked with the BGCs and designed for reversible capture of the biogas generated therein. A waste input system operatively linked to the BGCs is used to feed waste from one or more sources of waste thereto. Biogas generation within the BGCs is optionally promoted by retention of at least part of the waste within for a time period sufficient for release of gases due to degradation or by using means for promoting microbial processing such as heating means, centers for applications not limited to electricity production, use as fuels and use for chemical synthesis. The gas utilization centers maybe located either locally at the individual sources of waste or at a centralized location.
