With the rise in consumption of raw materials, plastic processors are facing higher political and social demands to use a greater proportion of recycled materials. Companies such as MultiPet GmbH, a recycling company which processes used PET materials flakes, make this transition possible. Along with their sister company Multiport, which specialises in making HDPE compounds from packaging waste, they are considered important suppliers of secondary raw materials for the plastics processing industry.
MultiPet GmbH is part of Veolia, a globally active environmental service provider. MultiPet processes discarded PET bottles and trays high-quality recycled PET flakes that are pure enough to be used by plastic processors to new products and containers.
MultiPet receives pressed bales of pre-sorted PET waste. After the bales are broken up, plastics are first checked for impurities, then ground flakes and intensively washed.
The Flake Purifier+ multi-sensor sorting s from Sesotec come 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 s separate discoloured materials, foreign plastics and metals from the flakes.
Sesotec 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.
At MultiPet, the Flake Purifier+ s 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”, says Herbert Snell, Managing Director of MultiPet GmbH. “This makes our sorting processes even more efficient.“ Sesotec‘s scope of delivery was complemented by a turn-key material handlingup which included steel work platforms and material conveyance s, simplifying integration the overall .

Schönberg, Germany-based Sesotec GmbH says its equipment is helping MultiPet GmbH, a subsidiary of France-based Veolia that operates in Germany, in its efforts to process discarded polyethylene terephthalate (PET) bottles and trays recycled-content PET flakes “that are pure enough to be used by plastic processors to new products and containers.”
“With the rise in consumption of raw materials, plastic processors are facing higher political and social demands to use a greater proportion of recycled materials,” states Sesotec. The firm says companies such as MultiPet and its sister company Multiport, which specializes in making high-density polyethylene (HDPE) compounds from packaging scrap, are growing in importance as suppliers of secondary raw materials for the plastics processing industry.

Sesotec describes itself as a maker of machines and s for contaminant detection and material sorting, with a focus on the plastics, recycling, food, chemical and pharmaceutical industries. Sesotec has subsidiaries in Canada, China, India, Italy, Singapore, Thailand and the United States, combined employing some 540 people.
