TECHNOLOGY FOCUS - BIOLOGY - Preferred Process: The biomass is subjected to: a first mincing process before the press-molding process, and a second mincing process after the pressing process. The process further comprises drying the biomass by hot gas or a microwave heating process under a pressure, preferably ambient pressure. The different biomass are dried separately and blended for compression or press molding process. During the compression molding, the biomass in the form of granulates, press-molds, pellets or briquettes are obtained.Preferred Components: The dry biological wastes are wastes from papers, cardboards, natural textile fibers and wood, which are press-molded alternatively or together. The wet biological wastes are wastes from vegetable tissues from garden-, park- and cemetery- wastes including leaves, branches, roots and other plant components; wastes from the preparation and processing of vegetable tissues to food or animal fodder; wastes from the production of canned goods; wastes from the preparation and processing of fruit, vegetable, grains, food oil, cocoa, coffee, tea, tobacco, yeast and its extract, molasses, domestic and commercial kitchen wastes and decomposed straw; wastes from animal tissues; wastes from the preparation and processing of meat, fish and other food products of animal origin; wastes from the production of canned goods, animal excrements including stable muck and dung/liquid manure, sewage sludge, biological street sweepings and biological wastes from cleaning of sewers, other organic materials from natural substances such as fats and waxes, food oils and fats, which are press-molded alternatively or together.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The device comprises a drying mechanism (8) for drying the biomass before the compression molding process; a first mechanism (2) for mincing of the biomass, which is arranged upstream to the drying mechanism; a pressing mechanism (5) for mold-pressing of the biomass, which is arranged upstream to the drying mechanism and downstream to the first mincing mechanism; a second mechanism (7) for mincing of the biomass, which is arranged downstream to the pressing mechanism and upstream to the drying mechanism. The drying mechanism comprises a drying chamber, which is capable of heated by a hot gas, electrical heating and/or by microwave heating process; and a control mechanism for adjusting the pressure on the biomass during the drying process. The drying mechanism is optionally closed in a gas and/or liquid tight manner.
