A blade system for device for recycling mixed plastic is disclosed. Furthermore, a device and a method for recycling unidentified, unclean, and unsorted mixed plastic into reusable plastic mixture is disclose. The present solution allows the recycling of mixed plastic waste outdoors, both in warm and cold climate conditions. In the course recycling mixed plastic waste the mixed plastic waste is taken to a melting temperature, at which the mixed plastic waste is mixed in a molten state, and the organic and bacterial material is destroyed during the thermal processing. After the melting, mixing and thermal processing of the mixed plastic waste, the compaction process of the molten mixed plastic waste is performed. Volume compacting is performed, and the mass of mixed plastic waste in a molten state is rapidly cooled down, crushed, after-cooled and homogenized.
