The placement of the enormous amount of waste grape marc generated in all over the world is an increasing problem. By processing 100 kilograms of grape-vine approximately 20-25 kilograms of grape marc is produced. From this grape marc high agronomic value compost can be produced by the offered technology.The offered two-phase composting technology is suitable for composting of fresh grape marc and other subsidiary raw materials. After distillation an environmentally friendly end-product can be produced. The whole composting process is not longer than 70-90 days.The grape marc and vinasse compost produced by the offered technology is more advantageous than other composts and manures in many respects. Other composts and manure may contaminate the soil by their toxic element content, and may significantly reduce the amount and diversity of N-fixing and other useful bacteria.The grape marc compost contains high amounts of organic and inorganic colloidal constituents, which means it can be easily used as inocula.
