Alternative soil preparation, optimalization of biogas preparation

A process is provided to produce alternative'substrate or soil by converting waste materials and for biogas production. The biogas yield is optimised. Communal and agricultural waste is pretreated by ultrasound digestion or wetting, or particle size optimisation, or microbiological treatment, etc. The proposed solution is characterised by six interventions in the known biogas production technology to increase efficiency and optimise the biogas process as follows: * - The first intervention is the selection and grouping of the raw materials to ensure the formation of identical volumes of biogas and wettability. * - The second intervention is the treatment of waste feedstock with microbiological and/or physical methods. * - The third intervention is the preparation of waste feedstock. * - The fourth intervention is the optimisation of biogas production by utilising waste heat. * - The fifth intervention is gas cleaning, the reduction of gas dioxin and hydrogen sulfide contamination and, at the same time, the microbiological production of product(s), moreover, the burning of inadequate gas on the flare. * - The sixth intervention is the microbiological production of new product(s).
