NOVELTY - Solid fuel comprises a mixture containing 80 wt.% of selected biodegradable municipal and/or industrial waste of cellulose products, 80 wt.% of selected municipal and/or industrial waste of fibrous materials from natural textiles and fibers, 50 wt.% of sifted stabilized fractions of biodegradable waste, 25 wt.% of phytomass waste comprising biodegradable waste from forest husbandry, from tree pruning in towns and cities and/or from gardens, parks and/or straw chaff, 5-8 wt.% of tobacco waste, 5 wt.% of cork waste and/or 5-15 wt.% of stabilized municipal sewage sludge.    USE - The solid fuel is useful for a power industry (claimed) for boilers.    ADVANTAGE - The solid fuel contains exclusively selected biodegradable waste including both municipal and industrial wastes, different phytomass wastes and stabilized municipal sewage sludge to process the large amounts of various waste deposited in landfills without environmental contamination, thus obtaining a fuel of high heat content and low content of ash and sulfur compounds during combustion in boilers.    DETAILED DESCRIPTION - Solid fuel comprises a mixture containing 80 wt.% of selected biodegradable municipal and/or industrial waste of cellulose products, 80 wt.% of selected municipal and/or industrial waste of fibrous materials from natural textiles and fibers, 50 wt.% of sifted stabilized fractions of biodegradable waste, 25 wt.% of phytomass waste comprising biodegradable waste from forest husbandry, from tree pruning in towns and cities and/or from gardens, parks and/or straw chaff and/or press cake, sludges and other residues from plant produce and/or wood processing without polish and impregnants, 5-8 wt.% of tobacco waste, 5 wt.% of cork waste and/or 5-15 wt.% of stabilized municipal sewage sludge. An INDEPENDENT CLAIM is included for a method for manufacturing the solid fuel comprising mixing 80 wt.% of selected biodegradable municipal and/or industrial waste of cellulose products, 80 wt.% of selected municipal and/or industrial waste of fibrous materials from natural textiles and fibers, 25 wt.% of biodegradable phytomass waste, 5-8 wt.% of tobacco waste, 5 wt.% of cork waste to obtain a mixture and reducing the size of the mixture to 0.1-30 mm, drying the mixture in a high-speed mill, adding the obtained size-reduced mixture of biodegradable components placed in a milling and drying device and 50 wt.% of sifted stabilized fractions of biodegradable waste, subjecting the obtained mixture to further mixing, drying to remove 11-12% of moisture content, reducing the size of the mixture to 0.1-10 mm until a homogenous mixture is obtained depending on the type of boiler in which a fuel is to be used, and forming pellets or briquettes without adding any additional binders.
