Polystyvert uses a patented dissolution technology to process polystyrene waste into high quality recycled polystyrene. The dissolution method of advanced recycling takes plastic waste in its solid form and dissolves it in a solvent. Once dissolved, the process can mechanically and chemically separate contaminants and additives, before finally separating the original polymer from the solvent. The end-product is then a cleaned polymer that may be used as new raw material resin again.
Polystyvert’s in-depth purification technology offers the ability to treat all types of feedstock, from industrial waste to post-consumer streams. The technology can eliminate a wide range of hard-to-remove contaminants such as pigments and brominated flame-retardants. Recycled polystyrene pellets can then be used to manufacture various categories of polystyrene products, including food-grade applications.
INEOS Styrolution has strong sustainability goals to improve and increase the recovery of post-consumer polystyrene waste. This joint development agreement reinforces their commitment to explore continued research into advanced recycling technologies.
Ricardo Cuetos, Vice President, INEOS Styrolution Americas, Standard Products, said: “The purification capacity of Polystyvert’s technology is unique. The high quality of the final recycled polystyrene resin is essential to achieving a truly circular economy in key markets like food service packaging.”
Solenne Brouard, CEO of Polystyvert, added: “Dissolution is an efficient, low-energy technology which offers a cost effective solution to recycle polystyrene in a closed loop. Recycled polystyrene is produced at a competitive price. Thus, opening up the full potential for a circular economy.
“We are pleased to work with INEOS Styrolution to set up a truly circular economy for polystyrene. Our common goal is to recycle as much polystyrene as possible and a partnership as such, will make a difference."
