TECHNOLOGY FOR MANUFACTURE OF BEEF MANURE COMPOST

TECHNOLOGY FOR MANUFACTURE OF BEEF MANURE COMPOST

The company produces high quality, valuable fertilizer, compost, from litter and animal feed residues. The production of compost begins with the removal of cattle from the farms to grazing fields for the summer season. After removing the enclosures, manure is pushed into piles (90 m * 4 m * 1.8 m). In the piles, manure slowly starts to burn, initiating the composting process. In the first stage, with sufficient air, temperature and humidity in the piles, breakdown and fermentation of the starter materials begins. Various soil microorganisms are involved in this process. Bacteria and fungi break down proteins, sugar, cellulose, and fat. First of all, the bacteria begin their active activities. Their activity causes the temperature rise inside the pile, sometimes to +65 or +70 degrees. High temperature in a pile is a biological process of burning or oxidation. Later, temperature in the piles drops to +45 degrees. This is the moment for active proliferation of fungi and formation of gas. Hard-to-digest organic substances then break down into 22 durable substances that make up humus. This process is called rearrangement, it lasts for at least 2 weeks, resulting in immature compost mass. In the immature compost stage, the compost pile must be stirred 5-6 times. The company uses Menart shaker for this process. The machine shreds and, if necessary, moisturises the pile again, which rises to +70 degrees after each stirring. This way, by composting, within 8-10 weeks, during 6-8 stirrings, the compost will lose about 40% moisture, as well as evaporate 20-30% of organic matter released as carbon dioxide. The obtained raw material is additionally dried and processed at 75 degrees for at least one hour. This ensures quality according to the EU regulation.The remaining compost comprises about 1/3 of the original amount of manure. The compost matter is tested in an EU-accredited laboratory, and the report of chemical composition is then issued.
