PET recycling plant opens in Germany

PFR Nord — new PET sorting plant planned, built and installed by REDWAVE systems.

The Mensing Group of Companies in Hohenwestedt (Germany) has invested almost €10 million in the construction of a new PET recycling plant. The construction of the recycling plant is associated with the formation of PFR Nord GmbH in Hohenwestedt. About 30 new jobs have been added.

Since June 2013, the new processing plant for clear PET from PFR Nord GmbH is in operation. Around 100 tons of PET bottles are processed in this plant per day.

PET are purchased in bales at different qualities (80/20, 90/10, 95/5, etc.). The bales are opened and separated by a bale opener, then the magnetic parts are separated using an overbelt magnet. Films and fines are separated using a ballistic separator.

Following the ballistic separator, the 3D fraction is passed through an eddy current separator to isolate the aluminum.

The next step is the separation of contaminants, such as PVC using a REDWAVE sorting machine, which recognizes and reliably separates different plastic materials using near-infrared.

The color sorting, including recovery is done in the next steps. The sorted clear PET in the highest purity is shredded and washed, and sold as PET flakes after sorting.

The PET bails are opened up and separated using bail opener. The metals are separated using an overbelt magnetic separator and eddy flow separator. Films and fines are separated on a ballistic separator. Contaminants such as PVC and other plastics are then sorted out. Using multi-level sorting, a high-purity clear PET fraction is produced with a high efficiency. The pure and clear PET is shredded and washed to be sold as PET flakes.
