NOVELTY - A system (1) with a bunker space (2) and feeder system (3,3') for the storage and pre-treatment of waste (M) with organic components and/or biomass and/or organic waste for subsequent thermal treatment or production of synthetic fuel or compost in a suitable plant (18, 18a or 18b respectively), in which (M) can be rearranged in the space (2) by the feeder (3,3'), a liquid (11) can be fed into (M) from above and removed from (2), and (M) can be transferred by the feeder (3,3') to (18), (18a) or (18b).    USE - For the storage and pre-treatment of untreated and/or treated waste material with organic components, and/or biomass and/or organic waste, prior to dumping, thermal treatment, fuel production or composting.    ADVANTAGE - A simple system for the storage and pre-treatment of waste which enables the dewatering of organic waste material or biomass and/or an increase in its calorific value and/or a reduction in its quantity.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for    (1) a method for the storage and pre-treatment of waste material (M) as above by feeding (M) into a bunker space (2), rearranging (M) over a first period with the aid of a feeder (2), adding a liquid (11) from above and then removing it after passing through (M) so that aerobic hydrolysis of (M) occurs during and after the addition of (M) to the bunker (2), stopping liquid addition to enable static dewatering over a second period (while removing the emerging liquid from (2)), and then transferring the dewatered waste (M) by means of the feeder system (3) to a unit for thermal treatment (18), fuel production (18a) or composting (18b)    (2) a waste treatment plant (19) with a thermal treatment unit (18) or a fuel production unit (18a) or a compost-production unit (18b), plus a storage and pre-treatment system (1) as above    .    DESCRIPTION OF DRAWING(S) - The drawing shows one version of a waste treatment system (1) according to the invention.    bunker space (2)    feeder (3)    shaft (6)    liquid feed inlet (10)    liquid (11)    thermal waste treatment unit, fuel production unit or composting unit (18, 18a, 18b)    waste treatment plant (19)    liquid circuit (20)    purifier (21)    biogas plant (23)    solid (24)    biogas (25)    heater for liquid (H)    waste, waste with organic components, biomass and/or organic waste.
