Patent ID: 8221626

Claim:
A renewable energy microgeneration apparatus comprising: a portable processing container comprising: a mixing tank for mixing waste with a liquid, a macerating pump in fluid communication with the mixing tank that is configured to macerate the waste into smaller pieces, a plurality of small holding tanks in fluid communication with the mixing tank that are configured to perform at least one of a pasteurization thermophilic anaerobic digestion on the waste, a large holding tank in fluid communication with the plurality of small holding tanks that is configured to perform mesophilic anaerobic digestion on the waste after at least one of a pasteurization thermophilic anaerobic digestion is performed on the waste, and a de-watering unit in fluid communication with the large holding tank that is configured to dry what remains of the waste after mesophilic anaerobic digestion is performed on the waste; a controller for automating the flow of the waste between the mixing tank, the plurality of small holding tanks, the large holding tank, and the de-watering unit such that a user does not need to complete any tasks for performing mesophilic anaerobic digestion after the waste is loaded into the mixing tank; and a portable gas storage container comprising a gas storage tank that is configured to store biogas generated by the mesophilic anaerobic digestion, wherein the portable processing container and the portable gas storage container are configured to be transported to a site and placed in fluid communication with each other so the gas storage tank can store biogas generated by mesophilic anaerobic digestion in the processing container at the site.
