Bio-attributed styrenics. Performance powered by nature.

Our Styrolux® ECO and Styroflex® ECO product lines, made with bio-attributed styrene, are a sustainable solution that can also be used for packaging and flooring applications. By only changing the source of our raw materials, the physical properties and quality of Styrolux ECO and Styroflex ECO, such as high transparency, brilliance as well as impact resistance and toughness, remain identical to Styrolux and Styroflex made with fossil-based styrene.

What is bio-attributed styrene and how does it work?

Bio-attributed styrene is made by mixing renewable and fossil feedstock during production. The renewable feedstock is sourced from local household kitchen waste as well as Scandinavian wood waste. Therefore, this feedstock does not compete with food, does not compete with land use.

As both types of feedstock are mixed together during production, it is not possible to guarantee a dedicated concentration of sustainable feedstock in the final product. Therefore, a specific set of rules are used to track the total amount of sustainable resources that are input (raw material) and allocate an equivalent amount to the output (or end-product). This way, manufacturers can use renewable materials to make more sustainable products without altering their processes or infrastructure.

This bio-attribution process has been certified by the International Sustainability & Carbon Certification (ISCC), which certifies the raw materials, supply chain and processing according to its internationally recognised sustainability standards.

Following an extensive audit of the production site in Antwerp, our entire supply chain has been certified to be socially responsible, environmentally sustainable and credibly sourced, ensuring that our operations are in line with the highest legal, environmental, social and management requirements.

Two bio-attributed versions for all our Styrolux® and Styroflex® grades produced in Antwerp are now available: the B60, where 100% of the fossil-based styrene is replaced by bio-attributed styrene and the B30, where 50% of the fossil-based styrene is replaced by bio-attributed styrene.

Why companies should consider styrenics products sourced from renewable feedstock?

This bio-attributed approach enables an easy transition from fossil to renewables as it offers a drop-in solution. We can ensure sustainable processing and, in that way, significantly reduce GHG emissions along the value chain and avoid the use of fossil fuel.  Our customers have no compromise in performance, no product development necessary, no need to adapt technology and no new regulatory approvals needed.

This makes Styrolux ECO and Styroflex ECO an ideal solution for millions of products, such as food packaging, but also medical devices, durable household goods and construction materials.
