Abstract: Biotechnological land filling process comprises examining the recyclability of delivered and/or existing material and organic input material; initiating strong exothermic microbial material land filling process after blending the input material in an open temporary landfills; converting facultative anaerobic land filling phase and the microbial activities by facultative anaerobic bacterial populations; and balancing the mass of the raw land filling substrate obtained by the biotechnological treatment by the renewed addition of mineral materials. Biotechnological land filling process (for economical and ecological large scale production of natural, high quality land filling substrates by a combined biotechnological land filling of mineral and organic input materials, which are obtained during the preparation of industrial goods, industries of communal economy, industry, energy industry, food processing industry, agriculture, forestry and mining industry (as un avoidable waste, remnants and raw material) by bioprocess engineering method and for improving the environmental conditions, sustainable and holistic intensification of metabolic activities of aerobic and/or facultative anaerobic bacterial population and fungi by using substrate fixed starter cultures, for stably replicating the soil functions in natural soil and improving the sustainability and effectiveness of specific soil regulation optionally for environmental protection technology or methods) comprises (a) examining the recyclability of the delivered and/or existing material and organic input material, separately introducing a specific vol.% of the materials into a material-specific temporary storage region, further mechanically mixing and homogenizing the substrate or structure material coated with a layer of active bio film/starter culture and raw landfilling substrate with the input material, where the step (a) takes place in composition phase; (b) initiating strong exothermic microbial material land filling process after blending the input material in an open temporary landfills at an induction time of 1-3 hours, increasing the temperature from 55-70[deg]C for 12-48 hours, maintaining the temperature level by blending the optimal raw ore structures developed in the input material and/or by mixing and aerating the temporary land fills for 1-5 days, converting the low concentrated high-molecular organic carbon compound (which can be fragmented easily by the addition of an aqueous enzyme solution and/or extracellular enzymes released from autochthonous bacterial population or starter cultures) into low-molecular organic carbon compounds and semi-biomass and semi carbondioxide (by aerobic bacterial populations), where the mass and temperature of the developed preliminary land filling substrate is reduced to 15-40% (when compared with the initial mass of the input material due to the decomposition of the available organic carbon compounds) and 35-37[deg]C, respectively, that active and decayed biomass becomes raw humus, such that self-adjustment of mesophilic process and environment conditions in the preliminary land filling substrate are controlled and maintained at a defined time using 0.1-0.3 m of strong microbially active coat of temporary land fills harboring biologically active substrate mixture, where the step (b) takes place in an aerobic intensive landfilling phase; (c) converting the facultative anaerobic land filling phase and the microbial activities by facultative anaerobic bacterial populations, converting the hardly degradable high concentration and molecular organic carbon compound in the land filling substrate to biogas with in 2-4 weeks, filtering the biogas, by flowing through the coat and converting to biomass, reducing the developed raw land filling substrate to 5-30%, by the decomposition of the available organic carbon compounds, and mechanically separating the substrate material coated with an active biofilm layer and raw land filling substrate and recycling into the step (a), where the step (c) takes place in a facultative anaerobic landfilling phase mesophilic process and environment condition; (d) balancing the mass of the raw land filling substrate obtained by the biotechnological treatment by the renewed addition of mineral materials, spreading the substrate enriched with mineral materials of 0.3-0.5 m thick layer in the region, which is priorly occupied by the temporary landfills for post-land filling, decomposing the high molecular organic carbon compounds such as lignin and cellulose (which are not-decomposed priorly by the facultative anaerobic bacterial populations) by fungi and converting to humic substance, incorporating the formed humus into the mineral matrix of the soil and planting the grass, which are left untouched for 6-8 weeks to obtain a natural, high quality land fill substrate with lasting complex active and specific or general soil regulation functions, where the step (d) takes place in a post landfilling phase, thermophilic process and environment conditions.
