TECHNOLOGY FOCUS - AGRICULTURE - Preferred Components: The mineral or input materials are natural mineral soil, un avoidable wastes but pretreated wastes, remnants, raw materials from food, agriculture, forest and communal economies and organically loaded soils, whose grain fraction is between the lower and upper grain width of the natural mineral soils (e.g. power station ashes, flue-gas desulfurization gypsum, cinders, soil excavation, recycled building materials, remaining of demolition, excavation remaining from the surface mining industry, dead rock from the underground mining industry, sediments, dumps and waste heaps), organic/input materials with or without autochthonous bacterial populations or starter cultures, natural humus, peat, biocomposts, clarification dredges, green cuts, river sediments, sea sediments or harbor basin sediments. The input material blend is obtained by sequentially adding and mixing the organic materials with or with out autochthonous bacterial populations (greater than or equal to 1 vol.%), mineral materials with pollutant residue (greater than or equal to 1 vol.%), organic materials with autochthonous bacterial population (greater than or equal to 1 vol.%), structure and/or substrate materials with or without fixed starter cultures (greater than or equal to 0 vol.%) and aggregates for adjusting of an optimum C/N ratio (greater than or equal to 0 vol.%). The substrate or structure materials, processed waste and residual substance of synthetic and/or natural substances, which are obtained during the preparation of economical goods and industries, and have a specific surface are of greater than or equal to 0 m2/m3 and gap volume of greater than or equal to 0 vol.%. The microbially active coat on the temporary land fills acts as heat producing- and isolating- layer and as surface bio-filter, through which biogas gets deodorized and/or oxidized. The optimized raw ore structure of the temporary land fills has a grain density of greater than or equal to 1 g/cm3, a total gap volume of greater than or equal to 1 vol.%, a field capacity of greater than or equal to 1 vol.%, porosity of greater than or equal to 1 vol.% and air capacity of greater than or equal to 1 vol.%. The specific soil regulation and general soil are determined by the humus portion (greater than or equal to 25 vol.%) in the mineral soil matrix and by the physical parameters of the soil such as dry bulk density, grain density, porosity, field capacity, plant-available usable field capacity, permanent withering point and water permeability factor. Preferred Process: The self adjusting mesophilic process and environment condition step (c) and the self-adjusting thermophilic process and environment conditions in step (d) are detected and controlled by the known process-relevant data, which are validated by liquid collecting devices patent No. 4408811. The process takes place by batch-wise, quasi-continuously, continuously in open, closed temporary land fills, process engineering plants or devices with or with out housing.
