Abstract: A system for processing material, for example recycled material, comprises a compacting device (101) for compacting the material and a treatment device (102) for agglomerating, pelletizing, or nozzle-extruding the compacted material. The compacting device comprises a compacting chamber (103) and a compacting element (104) that is moveable in the compacting chamber to reduce the volume of the compacting chamber so as to compact the material to be delivered to the treatment device. As the material is compacted prior to being agglomerated, pelletized, or nozzle-extruded, supply of the material to the treatment device can be more reliable especially when the material is chopped waste plastic or other fluffy material including much air. Furthermore, efficiency of the agglomeration, pelletizing, or nozzle-extruding is improved because the compacting increases density of the material prior to the agglomeration, pelletizing, or nozzle-extruding process.
