LyondellBasell announced the company has obtained the International Sustainability and Carbon Certification (ISCC) PLUS certification for certain grades of polyethylene and polypropylene produced at four of its U.S. manufacturing sites. ISCC PLUS certification is a globally-recognized system for providing traceability of recycled and renewable-based materials across the supply chain. ISCC PLUS certification enables LyondellBasell to extend its Circulen suite of products to customers in North America and offer mass balance certificates for these products. The company will begin North American Circulen production with its CirculenRevive products, which are polymers produced from plastic waste through an advanced recycling process1, initially using feedstock provided by third parties. LyondellBasell expects to gradually ramp up production to meet growing demand over the coming years. LyondellBasell secured the certification for its crackers in Channelview, Texas and its polymer sites in Lake Charles, Louisiana; La Porte, Texas; and Clinton, Iowa. The company plans to broaden the ISCC PLUS certification to its other North American polymer plants. The ISCC PLUS certification is part of the company's multi-pronged approach to help advance the circular economy. In addition, LyondellBasell continues to develop its own proprietary advanced (molecular) recycling technology to enable a more efficient chemical conversion process and use less energy than other technologies.
