International. In addition to styrene, the company sources many other sustainable equivalents of fossil raw materials. Biocircular acrylonitrile is used for other types of ion exchange resins.
Lanxess and TotalEnergies start a cooperation on the supply of biocircular styrene. Unlike conventional styrene, the raw material used by TotalEnergies is based on resin oil, which is derived from a tree resin and is a by-product of pulp production.
Lanxess uses styrene to produce sustainable ion exchange resins. These products are mainly applied in wastewater treatment and chemical process streams as well as in the food industry.
The sustainable origin of styrene is certified according to the mass balance approach of the ISCC PLUS (International Sustainability and Carbon Certification) standard.
Under the mass balance approach, certified and non-certified materials are physically mixed, but kept separate in accounting.
The method allows companies to document and track sustainable materials through the complex production process and ensures full traceability throughout the entire supply chain.
The ISCC PLUS certification of styrene is an important requirement, as Lanxess also offers its products according to this certification standard and therefore relies on the same transparency for its raw materials.
"Our customers are increasingly asking for sustainable solutions, and raw materials with a low carbon footprint are a key lever here. By partnering with TotalEnergies, we can further expand the respective offering for our customers," said Lanxess Head of Global Logistics and Procurement Marcel Beermann.
"We are pleased to form this partnership with Lanxess, which demonstrates TotalEnergies' ability to offer sustainable products to its customers, helping them reduce their carbon footprint," said JeanFrançois Renglet, Vice President of Total Refining and Chemicals' Base Chemicals Chemical Division.
"This is a perfect illustration of the guidance taken by TotalEnergies' Refining and Chemicals arm to develop lower-carbon products, in line with TotalEnergies' Climate Ambition to reach net-zero emissions by 2050, together with society," Renglet added.
In addition to styrene, Lanxess already sources many other sustainable equivalents of fossil raw materials. Biocircular acrylonitrile is used for other types of ion exchange resins.
The preservative Preventol is also available with various blends of sunflower oil-based fatty acids. Adiprene Green brand prepolymers contain starch-based polyether polyether polyols.
The intermediate Scopeblue trimethylpropane consists of about half sustainable N-butylaldehyde. The Tepex Scopeblue compound is based on flax and polylactic acid. And Durethan Scopeblue high-performance plastic uses biocircular cyclohexane and waste glass.
