NOVELTY - The method comprises generation a heat energy carrier in a first energy generation module 1 for drying the biogenic substitute fuels, drying the biogenic substitute fuels to a selected dry substance content in a substitute fuel processing module 2 using the heat energy carrier of the module 1, and introducing the dried substitute fuel from the module 2 into a thermal recycling plant in a sewage sludge recycling module 3 under the production of combustible product gas. The energy generation in the module 1 is carried out by a biomaterial treating process consisting of gasification process.    USE - Method for locally recycling biogenic substitute fuels such as sewage sludge and biological organic recyclable waste material such as parts of plants from agricultural and garden tree leaves, stems, straw, animal waste such as manure, abattoir waste, waste sorting plants, bagasse, algae from the wastewater treatment, waste wood, small timber and seaweed.    ADVANTAGE - The method is capable of economically, efficiently and safely recycling the biogenic substitute fuels with less energy consumption.    DETAILED DESCRIPTION - The method comprises generation a heat energy carrier in a first energy generation module 1 for drying the biogenic substitute fuels, drying the biogenic substitute fuels to a selected dry substance content in a substitute fuel processing module 2 using the heat energy carrier of the module 1, and introducing the dried substitute fuel from the module 2 into a thermal recycling plant in a sewage sludge recycling module 3 under the production of combustible product gas. The energy generation in the module 1 is carried out by a biomaterial treating process consisting of gasification process, pyrolysis process, combustion process (furnace combustion, reciprocating grate combustion, incineration combustion, rotary kiln combustion and fluidized bed combustion) under steam generation and discharging process of the heat energy occurred during the heat treatment. The module 1 is an incinerating plant, coal-fired power plant, lignite-coal power plant, cement factory, steel plant, geothermal plant or solar thermal power plant, combined heat and power plant with an organic rankine cycle-process or a power heat coupling plant with a gas engine drive. The heat treatment of the biogenic fuel in the module 1 is carried out by a multi-stage gasification system, where one stage is a primary stage gasification system and the combustion of the produced product gas is carried out in a second stage. The heat treatment in the module 1 takes place in parallel operation when the power-heat coupling is used for generating the electrical and thermal energy. The heat energy carrier is produced in the module 1 as low-temperature heat carrier up to 90 degrees C in the form of hot water, middle temperature heat carrier up to 150 degrees C in the form of hot steam or high-temperature heat carrier over 150 degrees C than thermal oil and is stored under others for drying the residual material in the module 2. The product gas from module 1 and 3 is partially recycled by a plant consisting of low nitrogen oxide (NOx) burner or Flox (RTM: Flameless oxidation for heating closed or enclosed spaces) burner, continuous air staging (COSTAIR) burner or fuel cell, methanol synthesis plant, methane synthesis plant, Fischer-Tropsch plant, drying- and vaporizing system, latent heat carrier, gas engine in the combined heat and power plant operation and a plant for an organic rankine cycle-process of a power-heat-coupling/steam turbine drive, gasification system, pyrolysis system, solid combustion and secondary combustion chamber and is partially recycled as fuel in module 1. The produced carrier heat energy from module 3 is stored into module 2 for drying the residual material. A phosphorus recovery is carried out after module 3. The waste heat of the module 1, module 2 and module 3 is converted into kinetic or electrical energy by a module 4 connected to the module with an upwind plant. An INDEPENDENT CLAIM is included for a plant for locally recycling biogenic substitute fuels such as sewage sludge.
