ECOLOGICAL AEROBIC PROCESS FOR THE BIODEGRADATION OF THE MIXTURE FORMED BY THE USE OF EXCESS BY-PRODUCTS FROM THE WOOD WORKING INDUSTRY AND BEER MAKING INDUSTRY, AND THE RESULTING PRODUCTS: ECOLOGICALORGANIC BIOFERTILIZERS

摘要

The invention relates to a process for obtaining an agricultural fertilizer. According to the invention, the process consists in mixing, in a ratio of 1 : 1, hardwood and softwood bark as well as softwood sawdust in a ratio of 1 : 1 in relation to the total amount of bark and Saccharomyces carlsbergensis yeast suspension, up to obtain a 45% humidity of the solid mixture which is further subjected to a biodegradation process at the temperature of 60°C for 8 months, wherefrom there is obtained an organic fertilizer with a C/N ratio of 8.
