Abstract: A portable and modular renewable energy microgeneration apparatus is disclosed that includes at least four modular units. The first modular unit includes a mixing tank and a chopper. The second modular unit includes a buffer tank, a liquor tank, and a pasteurization tank that pasteurizes waste that has been mixed with liquid from the liquor tank by the mixer, chopped into smaller sized components by the chopper, and pre-warmed by the buffer tank. The third modular unit includes a digestion tank that performs anaerobic digestion on pasteurized waste received from the pasteurization tank. And the fourth modular unit includes a gas storage tank that stores gas generated by the waste in at least one of the mixing tank, the chopper, the buffer tank, the liquor tank, the pasteurization tank, and the digestion tank. Each of the four modular units is both portable and modular.

Abstract: A renewable energy microgeneration apparatus is disclosed that includes a mixing tank that mixes waste with a liquid, a buffer tank that receives and pre-warms the mixed waste, a pasteurization tank that pasteurizes on the pre-warmed mixed waste, a digestion tank that performs anaerobic digestion on the pasteurized waste, a de-watering device that separates liquid digestate and removes salt from the liquid, sensors that measure salinity and biogas quality, and a controller. The controller causes the transfer of digestate from the digestion tank to the pasteurization tank to the dewatering device, causes the de-watering device to separate the liquid and remove the salt from the liquid, monitors the salinity of the liquid and the quality of biogas using the sensors, and causes the mixing of the liquid with the waste and adjusts the feed rate of the waste to reduce the salinity of the waste and increase methane production.

Abstract: A portable renewable energy microgeneration system is disclosed. The system comprises one or more holding tanks that are configured to perform anaerobic digestion on waste in a multi-phase process using bacteria and a controller configured to automatically control the multi-phase process and to re-use the bacteria. The controller re-uses the bacteria by removing at least a portion of the liquid from the waste after anaerobic digestion is performed on the waste and using the at least a portion of the liquid to wet other waste and repeat the multi-phase process.
