DePoly builds demonstration plant for chemical PET recycling

The plant is to process PET waste into virgin-quality raw materials.

In a press release, the Swiss company announced the start of construction for its first PET recycling plant in Monthey, Switzerland. The new plant would be used for demonstration purposes and would be able to process up to 500 tons of unsorted, untreated and mixed textile and packaging waste made of PET and polyester per year in a depolymerization process. The end products from the processing of household and industrial waste are reportedly the PET precursors terephthalic acid (PTA) and mono ethylene glycol (MEG). The demonstration plant is expected to go into operation at the end of the first half of 2025. This would create up to 30 direct and indirect jobs in the region. The technology used in the plant would enable PET plastics to be broken down into their raw monomers in virgin quality in an energy-efficient manner. The resulting monomers could then be used to manufacture new PET products. DePoly 's aim is to scale up commercial production facilities worldwide for customers in the clothing, food and automotive industries.
