Abstract: There is disclosed a system, method and apparatus for generating renewable energy from common waste streams in a low-carbon manner. This system is modular and applicable to operations of a range of sizes. The system comprises a waste homogenization system; a feedstock preparation component involving dilution, nutrient adjustment, and mixing; a pretreatment tank; a hydrolysis tank; and an optional photosynthetic bioreactor. Through use of the system, organic waste is converted into biohydrogen (H2) and/or biomethane (CH4). The choice between producing each gas individually or in combination is controlled via selective treatment of the incoming waste.

Abstract: There is disclosed a modular anaerobic digestion point-of-waste to renewable energy system. The system is directed to a modular and scalable anaerobic digestion system for point-of-waste use. The System includes a pre-treatment process for removing inhibitory nutrients from a feedstock, an in-treatment process for providing clean renewable energy and a post-treatment process for further providing clean renewable energy for subsequent use. The System includes a leaching bed; a liquids tank; a mixing tank; an anaerobic digester reactor; a precipitation tank; a stripping tank; a hydrogen sulfide scrubber; a water remover; a gas bladder; a dewaterer; and a flare system.
