TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The straw and/or straw-containing residues or organic waste are used as fermentation substrates. The dry material content of the straw is at least 10%, preferably at least 50%. The straw-containing waste materials exist from solid manure and/or a mixture of manure and straw and/or dry manure from poultry and the dry material content of these feedstocks is at least 10%, preferably at least 50%. The dry material content of the organic waste is at least 10%, preferably at least 75%. The dry material content of the renewable resources is at least 10%, preferably at least 75%, of the dry material content of the total fresh mass. Preferred Method: The greenhouse gas reduced biomethane or the greenhouse gas reduced residual biogas enriched with biomethane is not mixed with natural gas. The pure greenhouse gas reduced biomethane or mixed with natural gas is fed into a natural gas- or biomethane-network. The method further comprises preparing fuel production digestate from the anaerobic bacterial fermentation to alternative fuels, preferably into fuel pellets or fuel briquettes, which substitute fossil, greenhouse gas releasing fuel oil or fossil, greenhouse gas releasing natural gas or fossil or greenhouse gas releasing coal. The recuperated regenerative CO2 is processed by reforming with the addition of hydrogen to biomethane and/or to biomethanol. The straw or the straw-containing residual substances are submitted for the purpose of the exposure of the lignin structures to a pretreatment, preferably the mechanical pretreatment of the grinding or the chemical pretreatment of adding in acid-containing solutions or the thermochemical pretreatment with saturated steam or the thermomechanical pretreatment by steam explosion or the thermochemical pretreatment by thermography hydrolysis or the chemical pretreatment by mixing with solid manure or with liquid manure or the biochemical pretreatment with exo-enzymes. The anaerobic bacterial fermentation takes place according to the procedure of the solid fermentation (dry fermentation), preferably in fermenters of the type of garage and preferably with post-fermentation in a fermentation residue bunker. The starting materials are transported with at least one truck or tractor for the biogas plant, for its drive as fuel, less than 120 g CO2-equivalent/kWh greenhouse gas-reduced biomethane or an appropriate natural gas equivalent is used, to at least 10%, preferably to at least 80%. As per year more than 1000 tons, preferably more than 100000 tons, of biomass as wet fresh mass per biogas plant are used. The biogas produced in at least one fermenter or biogas fed from external sources or gas mixture consisting of these two gases is performed with an amount of: less than 30%, preferably less than 10%, in the strand electricity; or more than 35%, preferably more than 90%. The biogas produced in at least one fermenter or biogas fed from external sources or gas mixture consisting of these two gases is performed with a flow rate of more than 100 Nm3/hour, preferably more than 2000 Nm3/hour, in the strand electricity. The biogas produced in at least one fermenter or biogas fed from external sources or gas mixture consisting of these two gases is streamed with combined heat and power technology or fuel cells or with organic Rankine Cycle technology, preferably with an electrical efficiency of greater than 40%, preferably greater than 43%. The biogas produced in at least one fermenter or biogas fed from external sources or gas mixture consisting of these two gases is conducted with an amount of at least 30%, preferably at least 90%, in the strand of biogas scrubbing/CO2 separation/CO2 recuperation. The biogas conducted in the strand of biogas scrubbing/CO2 separation/CO2 recuperation: reaches a flow rate of at least 100 Nm3/hour, preferably at least 2000 Nm3/hour; and exhibits a total mercury pollution according to LCA of less than 120 g CO2-equivalent/kWh biogas, preferably less than -20 g CO2 equivalent/kWh biogas. From the biogas that is conducted in the strand of biogas scrubbing/CO2 separation/CO2 recuperation, regenerative CO2 is separated and collected, where the separation of CO2 takes place with the method of pressure swing absorption, preferably by the method of the pressurized amine scrubbing process, preferably with a cold process (cryogenic method). The fermentation waste is discharged from the anaerobic bacterial fermentation as fertilizer on agricultural land or forestry used areas, and mineral fertilizers are replaced. The transport of biogas takes place in mobile liquid tanks or in mobile-pressure tanks. CO2 derived from fossil fuels is replaced next to the industrially employed recuperated regenerative CO2. The hydrogen used for the process step of CO2-reforming is produced by electrolysis, where the electricity used for this purpose is preferably from renewable sources. For the electrolysis, nuclear- or fusion power is used. The mixing of the biomethane takes place with natural gas, such that the biomethane is fed into a natural gas network and mixed with the natural gas. At least one tank, in which the biomethane, or another natural gas equivalent, or the biomethanol or CO2 is bottled, is mobile. The tank is transported to the point of sale or to the place of consumption, preferably with a truck. The vehicles, which transport the feedstock to a biogas plant, are covered. The biomethanol is mixed with ethanol and/or gasoline. The biomethane or an appropriate equivalent of natural gas and/or recuperated CO2 is compressed for the purpose of transporting and is packaged in pressurized tanks. The ashes of the burned fuel pellets or fuel briquettes are recuperated and a fertilizer production is introduced. EXAMPLE - No suitable example given.
