TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The inorganic material is rock flour of clay, marl and/or marl stone; rock flour of limestone, preferably with a particle size of less than 200 mu m; preferably powdery white lime hydrate, preferably with 69-75% of calcium oxide and 0.2-2.5% of magnesium oxide and in a bulk density of 0.1-0.3 kg/dm3; bentonite, preferably thin bentonite with a minimum content of 60% smectite; or zeolite, preferably clinoptilolite, preferably with a particle size of less than 200 mu m. A mineral carrier e.g. bentonite and/or mineral carrier-mixture is mixed with lignin derivatives and/or lignin cleavage products, preferably with the carrier and/or carrier mixture and contains a content of lignin derivatives and/or lignin products of greater than 70 %, as organic mineral nature additive. The amount of organic residual substances and inorganic residual substance is 30-80 wt.% and 0-45 wt.%, respectively, related on the dry substance. The inorganic substance is in the form of mineral additive (3-40 wt.%). The lignin derivatives are calcium lignin sulfonate, sodium lignin sulfonate, ammonium lignin sulfonate or magnesium lignin sulfonate.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The mixed product is present as solid phase, preferably in granular, fibrous or pasty form. The moisture content of the mixed product is 10-45 wt.%, related on the dry substance. The mixed product is present in air-dried, burned, ceramic and/or sintered form. The organic materials are sewage sludges, paper sludges, plastic materials, wood, compound materials made of plastic and wood, products of the mechanical-biological residual materials, animal flours, oil residues, hydrocarbon and hydrocarbon derivative residual products comprising e.g. tar paper, tar surface and/or inorganic residual products, e.g. sedimentary materials, gravel-wash sludge, storage space sediments or demolition materials, power station fly ash and/or other ashes. The amount of organic-mineral nature additive is 0-18 wt.%. The mixed product is reacted with a hydrophobizing agent. EXAMPLE - No suitable example given.
