Method and plant for pre-treatment of source separated wet organic waste from house holds, institutional house holds etc., comprising shredding of the waste in a course shredder unit (2), allowing the shredded material to fall down to a fine dissolver unit (3) where more heavy objects are removed, adding a process liquid until a desired content of solids of 6 to 12 % is achieved, shredding the mixture with a rapid rotating paddle mechanism, transferring the mixture to a separation unit for plastics, and transportation of the remainder mixture into a plant for production of biogas and decomposing remainder.
