solid fuels. SUBSTANCE: invention relates to production of solid fuels from municipal waste water sediments and vegetable- and wood-origin cellulose-containing materials or from woodworking, paper-and-pulp industry wastes, or from analogous wastes from other industries. cellulose-containing material is added to sediment before mechanical dehydration thereof in amount less than 30% based on solid weight of fuel and resulting mixture is ground until homogeneous paste is obtained, in which two types of fibers are formed: those with length 0.1- 1.0 mm and those with length less than 0.05 mm. Homogeneous paste is treated with flocculants, mechanically dehydrated, dried, and compressed in the form of fuel elements: briquettes or granulates. EFFECT: simultaneously solved environmental and economical problems. 2 tbl
