MultiPet GmbH, a recycling company which processes used PET materials into flakes and is part of Veolia, uses FLAKE PURIFIER+ multi-sensor sorting systems from Sesotec to ensure the highest quality in PET flake production.

 

FLAKE PURIFIER+ units are designed especially for use in plastic flake processing and are characterized above all by ease of operation and heightened throughput capacities.

 

MultiPet processes discarded PET bottles and trays into high-quality recycled PET flakes that are pure enough to be used by plastic processors to create new products and containers. The company receives pressed bales of pre-sorted PET waste. After the bales are broken up, plastics are first checked for impurities, then ground into flakes and intensively washed.

In the recycling plant of MultiPet, FLAKE PURIFIER+ systems separate discoloured materials, foreign plastics and metals from the flakes.


Then, The FLAKE PURIFIER+ multi-sensor sorting systems from Sesotec come into play directly after the ground material has undergone a two-stage density separation process involving two rounds of hot washing. At this stage, the sorting systems separate discoloured materials, foreign plastics and metals from the flakes.

At MultiPet, the FLAKE PURIFIER+ systems are equipped with multiple sensors for colour and material recognition. This enables MultiPet to produce PET flakes in batches of different colours and qualities for use as raw materials in the plastics processing industry. By using recyclates produced by MultiPet, plastic processors are reducing their CO2 footprint, contributing to climate protection and conserving resources.

 

“Sesotec’s processing technology enables us to keep the loss of good material to a minimum and makes our sorting processes even more efficient,” says Herbert Snell, Managing Director of MultiPet GmbH.
