VERFAHREN ZUR STICKSTOFFGESÄTTIGTEN INERTISIERUNG LIGNOCELLULOSEHALTIGER RESTSTOFFE UND FASERSTOFFE AUS NACHWACHSENDEN ROHSTOFFEN FÜR DIE VERWENDUNG ALS TORFERSATZ

摘要

Disclosed is a combinable abiotic or fermentative method enabling the production of peat substitutes based on materials and products containing lignocellulose from after-growing raw materials, said substitutes exhibiting characteristics similar to peat. The abiotic method involves reactions by caramelization at temperatures > 60 DEG C . Chemical and biochemical reactions are brought about resulting in an N bond in the high molecular fraction of the lignocellulose at temperatures < 50 DEG C by adding inorganic and organic compounds containing nitrogen in the presence of microbial biocenoses. The N charging lowers the N fixation from external mineral sources through microbial metabolism to values < 100 mg/l. Preferably, N charging of the lignocellulose through chemical bondings can be achieved by adding proteins or by inducing protein formation. The fermentative process in the presence of proteins results in dark brown coloring. Said process can be optimized by adding phenols, sulphur flowers and/or ammonium sulfate (pH reduction), active substances and plant nutrients and in the presence of selected types of microorganisms or type groups.
