As the demand for raw materials grows and political and societal pressures to increase recycled content intensify, more companies are turning their attention to plastic waste recycling. Companies like MultiPet GmbH, which produces PET flakes from used PET materials, and its sister company Multiport, specializing in HDPE compound production from HDPE packaging waste, are key suppliers of recycled secondary raw materials, known as recyclates, for the plastics processing industry.
As part of the global environmental services leader Veolia, MultiPet GmbH specializes in producing high-purity PET flakes from used PET packaging (bottles and trays). Our advanced processes ensure recycled materials of exceptional quality.
How does the recycling process work?
MultiPet receives pre-sorted PET waste in compressed bales. Once the bales are broken down, the pre-sorted plastics are first inspected for contaminants, then ground and thoroughly washed. Following a two-stage density separation process with dual hot washers, the FLAKE PURIFIER+ multi-sensor sorting systems from Sesotec take over.
These systems remove off-color flakes, foreign plastics, and metals from the plastic flakes. Designed specifically for plastic flake processing, the FLAKE PURIFIER+ devices stand out for their user-friendly operation and enhanced throughput. At MultiPet, the FLAKE PURIFIER+ systems are equipped with sensors for color and material detection.
This allows MultiPet GmbH to supply PET flakes in various colors and qualities as raw materials for the plastics processing industry. Additionally, using MultiPet's recycled products reduces CO2 emissions, contributing to resource conservation and climate protection.
Herbert Snell, Managing Director of MultiPet GmbH, states: “Sesotec's specialized process technology allows us to minimize the loss of valuable material, making our sorting operations even more efficient.”
The delivery to MultiPet was completed with a comprehensive setup tailored to the Sesotec sorting system. This includes a steel structure and material handling system for seamless integration into the overall plant.
