Abstract: The present invention relates to a method for the production of stable humus- and nutrient-rich and water-storing soil substrates with properties of anthropogenic soil types (Terra Preta) in which pyrogenic carbon, organic biomass, and/or natural mineral materials are used as initial materials in a fermentation process. The soil produced or treated according to the invention leads to a sustainably high soil yield such that mineral fertilizers are no longer needed for agricultural use. Moreover, the soil is suitable for use as a soil substitute, for use as a soil supplement, for greening developments, for preventing erosion, for improving regional water supplies, for preventing floods, for preventing climate change, for reducing carbon dioxide content in the atmosphere, for waste water cleaning and treatment, for exhaust air cleaning and building air purification, for creating material flow cycles from biogenic waste and/or waste water in order to develop and utilize land use and development systems.

Abstract: The present invention relates to a vertical-horizontal filter unit for the biological purification of polluted water, comprising an upper zone of a soil patch planted with plants, having inlets for the polluted water, and arranged underneath a sand layer with a lower filter zone made of gravel and at least one removal point for the purified water, wherein between the upper and lower filter zones a barrier layer with openings is arranged and the filter unit is sealed against the soil on the sides and at the bottom. The openings in the barrier layer are arranged along the edge and/or the barrier layer does not reach the edge of the patch completely. The invention is characterized in that the upper zone acts as an aerobically cleaning zone and the lower zone as an anaerobically cleaning zone.

Abstract: The invention relates to an ecotechnical installation for producing cultivation substrates, soil amendments, and organic fertilizers having properties of anthropogenic terra preta soil as well as a method for producing cultivation substrates, soil amendments, or organic fertilizers having properties of anthropogenic terra preta soil. The invention further relates to the use of said method or installation for utilizing unpolluted organic biomasses, biowaste, dirty water and sewage, mineral substances for generating current and/or heat and/or producing cultivation substrates having properties of anthropogenic terra preta soil. The invention finally relates to a circulation installation allowing a sustainable material flow management in order to utilize unpolluted organic biomasses, biowaste, mineral substances, etc. for generating current and heat and producing industrial water and cultivation substrates, soil amendments, or organic fertilizers.
