Cleaning up plastic scraps

Amut Recycling Division has been awarded two tenders by European waste management firms, each including twin plant for the rec­lamation and regeneration of thermoplastic polyolefin scraps into granules.

The water-saving concept behind Amut’s patented technologies involves treated water that can be reused thanks to special recirculation circuits.

For the first project, the two lines will work in parallel to process LDPE scraps, with a total output of 2.5 tonnes an hour. The thermoplastic scraps mainly consist of baled blown packaging films. To increase the plant’s flexibility, conveyor belts enable the two shredders to feed alternately two buffers on the lines.

Amut’s turbo washer and friction washer machines perform an intensive and continuous washing and rinsing action. The water can be thermally adjusted and conditioned by chemicals/detergents to increase the cleaning efficacy.

The flakes are separated out and conveyed to the centrifuge machine for the drying phase. This reduces their humidity and makes the material suitable for extrusion processes.

For the second project, Amut will supply twin lines for washing and pelletising of post-consumer plastic materials. Total output is 1.5 tonnes/hr of LDPE film or four tonnes/hr of PP or HDPE containers. The main advantage is the possibility of reclaiming either light or heavy polyolefins with the same machines one at a time.
