Abstract: The global wine and table grape industry, with annual sales exceeding US$100 billion, generates large quantities of cane pruning waste each year. This pruning is usually composted or burned as waste, often with a net cost incurred to the winery. Microorganisms, soil organisms or enzymes can degrade the “end-use” grapevine waste. In the European Waste Catalogue grapevine, waste is indexed as plant waste and as a part of biowaste. Since grapevine waste is subject to the aerobic treatment process, it is compost. Grapevine waste is subject to an anaerobic treatment process or treated by other methods, including mixtures with other materials like grape mark before/after treatment. The aim of this paper is to investigate quality and quantity of the compost types made of pruning waste, grape mark, and the mixture of both. Preparation of microbial fertilizers consists of the Bacillus and Pseudomonas straining and their placement, at an adequate amount, in all assemblage. Results indicate that the microbial biomass causes the improvement of natural degradation.
