The process is characterised by that the 60 to 70 mass % grape marc, 15 to 20 mass % farmyard manure compost, 30 to 10 mass % pre-treated wine lees, 3 to 4 mass % activated potassium trachyte and 12 to 18 mass % phosphorite are composted together in a layered prism in such a way that the individual layers of the prism are covered with advantageously at least 2 cm thick layer of oil containing waste of bleach earth of vegetable oil production and the stack is aerated by layers in the initial and thermophylic stages of pre-ripening then the stack is turned over after the pre-ripening and a mixture of 15 to 20 mass % of solid biomass and bed sludge and if desired 0.5 to 3 mass % perlite are added to it and the subsequent ripening is performed by turning up the stack material several times until taking on of 100 to 150 mg oxygen per kg of solid material per hour is reached. |
