SABIC has claimed an ‘industry-first’ in developing certified-circular polycarbonate (PC) resin and blends from the upcycling of post-consumer mixed plastics.
Made through advanced (chemical) recycling, the certified-circular PC – known as Lexan resin – offers a potential carbon footprint reduction of up to 23 per cent compared with its market equivalent, according to a SABIC lifecycle assessment study.
Part of SABIC’s TruCircle portfolio, Lexan is produced through the advanced recycling of post-consumer mixed plastics that might otherwise be destined for incineration or landfill.
Through pyrolysis, difficult-to-recycle used plastics is broken down into pyrolysis oil, which is then used as a feedstock to create certified circular building blocks for high-performance plastics.
Suitable for sectors such as healthcare and consumer goods, SABIC said the PC could work in identical process conditions as current non-circular alternatives.
The company suggested that the new PC demonstrates its ongoing commitment towards a circular economy for plastics, by increasing the availability of more sustainable products.
Lexan forms part of SABIC’s engineering thermoplastics (ETP) portfolio, which includes PC blends such as Cycoloy and Xenoy resins.
“In another significant contribution towards the advancement of a circular economy for plastics, we are proud to have developed a new solution that can help our customers to meet their sustainability targets and generate value by increasing the amount of recycled post-consumer mixed plastics they process,” said Abdullah Al-Otaibi, ETP and market solution general manager at SABIC.
“We are continuously broadening out sustainability offerings, and in ETP specifically, new solutions in our PC portfolio to help support our customers’ increasing needs for circular content and carbon dioxide footprint reduction.”
The PC is certified by the International Sustainability and Carbon Certification (ISCC) Plus scheme using a standardised mass-balance approach, which provides a method of confirming the recycled material content according to predefined and transparent rules.
SABIC said the ISCC Plus accreditation provides traceability along its physically-linked supply chain, from the feedstock to the final product, requiring a chain of custody based on the mass-balance system.
