NOVELTY - Method for using organic and other types of substantially organic waste where a residual fraction is obtained from two fractions which is shredded and mixed and pressed to obtain bio-decomposable and pasteurized liquid fraction, is new.    USE - Method of using domestic and other types of substantially organic waste to produce a fraction with a small content of biologically decomposable material.    ADVANTAGE - On account of the effective separation of the waste in a liquid and a solid fraction, a possible extraction of mollifiers is minimized, which are difficult to bio-decompose, from the waste to the liquid fraction.    DETAILED DESCRIPTION - Method for using organic and other types of substantially organic waste where a residual fraction is obtained from two fractions which is shredded and mixed and pressed to obtain bio-decomposable and pasteurized liquid fraction, is new.    The method comprises dividing the organic waste into a fraction, from which no biologically decomposable material has been removed and a residual fraction with a small content of biologically decomposable material characterized in that the waste is shredded and mixed and subjected to pressing for driving off liquid biomass. The waste is heated to temperature of pasteurization, and the liquid biomass subjected to a biological decomposition and the press residue removed for incineration.    An INDEPENDENT CLAIM is also included for a plant for using organic waste comprising a feed box (1) for supplying the waste delivered to a shredding and mixing mechanism to deliver the mixed, shredded waste to a press (10) with a pressing basket or nozzle (12), from which a liquid fraction is separated and conveyed to a subsequent bio-gasification, while a solid press residue is collected for subsequent incineration.    DESCRIPTION OF DRAWING(S) - The drawing shows a principal sketch of a plant for using organic waste by separating it into two fractions.    Feed box (1)    Lids (2)    Sucker (3)    Scrubber (4)    Helical conveyor (5)    Molehill (6)    Nozzles (8)    Worm conveyor (8)    Press (10)    Tube part (11)    Pressing basket (12).
