Mass of waste materials of biological origin for producing fuel for direct combustion, and process for producing fuel from waste materials of biological origin
Mass of waste materials of biological origin, and biodegradable, containing biogenic elements carbon, hydrogen, oxygen, sulphur, and nitrogen, for producing fuel for direct combustion, located in an aerobic environment in the presence of air oxygen and other atmospheric gases. It contains starting humidity of 40 to 70% by weight of water and at least 25% by weight of organic substances, while the total weight of the mass is at least 3,000 kg and is piled up to a height of at most 3 m to a formation having cross section along the vertical axis in the form of an isosceles or equilateral triangle or trapezoid, or rectangle. The waste materials of biological origin are sludge from municipal wastewater treatment plants and/or sludge from industrial wastewater treatment plants, and/or less sludgy materials, lignocellulosic materials and/or packagings and their parts from commercial and/or communal sphere, and/or other materials containing cellulose. Further, a method for producing fuel by processing the mass of was
