Process for the preparation of a new agent for obtaining valuable Fertilizer for initiation and Activation of anaerobic aerobic processes of waste materials vegetAles or animals

摘要

Compost for the preparation of a rich manure or allowing the beginning, respectively the activation, of the aerobic decomposition process in a vegetal or animal waste medium; this compost is based on grape stones still containing their natural oil and contaminated by the humicola and/ or actinomycetes spores. During the preparation of this compost the solids of the grape marc are submitted to aerobic decomposition: in a first phase, the sugar contained in the solids of the marc is transformed into alcohol, this alcohol being then subjected to an esterification; during the second phase, introduced by a lightening of the material for making the aeration easier, the substrate gets richer in humicola mycelium and in various thermophilic species of actinomycetes; the third phase, characterized also by a new lightening of the material, allows the microbial decomposition of the mycelium; thereafter, all the material is dried; the subsequent sieving allows the elimination of a fraction containing the stones. For the preparation of this compost it is also possible to proceed as follows: in a first phase, the sugar contained in the solids of marc is transformed into alcohol; the alcohol is esterified; then, the stones are crushed; thereafter, all the material is subjected to the decomposition, including the broken stones, during the second phase. The compost thus obtained may be used either for the priming of a heating decomposition of weeds, or for the activation of the decomposition occurring in the heapings of vegetable waste. With a view to producing a manure, it is also possible to add to this compost other appropriate materials.
