TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: In the processing device (III) a pulp (14) made up of waste and water, is mixable and it contains a mixing container and an agitator.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The waste is processed in the bioprocessing device (II) and mechanically homogenized in the processing device (III) by a homogenization process under the addition of water (13) and finally squashed by a dehydration process to generate the predominant solid waste part and predominant liquid waste part. The homogenization process is carried out in a mixing container (7) with an agitator and that the subsequent squashing is carried out in a dehydration device (9). The processing of the waste takes place by a homogenization process in the processing device is controlled for reaching a definite pulpy consistency and for retaining many organic substances in the predominant solid waste part by controlling at least one of the parameter (P-III) of the waste in the processing device (III), where the parameter (P-III) is a retention time and water content of the waste in the processing device (III) and also a shear strength of the waste and the regulation on the basis of parameter (P-III) takes place in such a manner that the predominant solid waste is funneled out of the processing device (III) after the dehydration process in comparison to its total weight has possibly high proportion of biomass, by which preferably without feeding of further energy a biological drying of the solid waste part is carried out, where: the warmth generated by the microbial decomposition of the part of the organic substances is enough for drying, while the rest of the part of organic substance remains in the dried waste part as biomass and the liquid waste part is funneled out of the processing device (III); and a part of the original soluble and finely suspended toxic matter in the waste is retained, so that the toxic matter content in the solid waste part is reduced.
