Method for preparing activated plant complexes and plant/organic matter complexes that are doped or overdoped, carbonated, and the uses thereof in particular in anaerobic digestion or biogas production

摘要

Preparing doped or overdoped plant complexes by covering a compost comprises: preparing 6-20, preferably 8-15 activated plant complexes (CV) by covering a layer of untreated straw with multiple smears of (6-20 or 8-15) plant complexes; mixing the dried CV material with 70-95 wt.% of carbonate including calcium carbonate to form a carbonate plant complex (CVC); performing aerobic fermentation of a plant compost, preparing a compost heap; collecting upper part of the compost located under the interface with the CVC layer; and sieving the final layer of 1 mm and overdoped plant complex. Preparing doped or overdoped plant complexes by covering a compost comprises: preparing 6-20, preferably 8-15 activated plant complexes (CV) by covering a layer of untreated straw with multiple smears of (6-20 or 8-15) plant complexes, where each one is obtained from a particular plant or plant material and the degradation of the products is above ground during 2-8 months, preferably 3-6 months or half buried in the ground for 18-24 months, preferably 2 years; drying the CV up to a concentration of 60-80% of solid materials; mixing the dried CV material with 70-95 wt.% of a carbonate including calcium carbonate to form a carbonate plant complex (CVC); performing, in parallel, aerobic fermentation of a plant compost containing 5-15% of organic matter during 3-6 days to produce a fermented compost fermentation (CP), preparing a compost heap CP by overlaying the CVC layer, preferably an upper layer of activated coarse material (GA) formed by the refusal of 1 mm sieve doped CVD plant complex obtained during a production of a lot or prior batch; collecting the upper part (d2) of the compost (CP) located under the interface with the CVC layer, where the GA layer is obtained, when it is no longer found to gassing top of the heap, without the CVD plant complex or with GA layer; and sieving the final layer of 1 mm and overdoped plant complex, by passing the sieve via pure or diluted minerals or organic minerals. Independent claims are included for: (1) doped (CVD) or overdoped (CVSD) plant complex products obtained by the method; (2) producing methane or methane-containing biogas, comprising introducing the digester into the at least one CVD or CVSD product; and (3) new industrial product including digestate and comprising double or triple of humic acids (140-200% higher).
