International. Stahl, a supplier of coating technologies, announces the successful recertification of two manufacturing sites, in Germany and the Netherlands, according to the ISCC Plus standard.
The recertification of the sites by certification body TÜV NORD means that Stahl can continue to expand its use of renewable raw materials in its polyurethane portfolio and beyond.
This will allow the company to offer customers more products containing attributed renewable raw materials. The development marks a key step in Stahl's supply chain transparency ambitions, with the aim of reducing greenhouse gas (GHG) emissions across the value chain.
ISCC PLUS certified products manufactured at Stahl's facilities in Waalwijk and Leinfelden include selected polyurethane coatings for flexible materials such as textiles, films and paper.
Polyurethanes are made from between 20% and 70% renewable attributed biomass and recycled content. These products have the same performance as traditional fossil-based alternatives.
Renewable content is measured and verified using the mass balance methodology. This is a calculation-based approach that tracks the flow of materials through complex supply chains.
Mass balance certified products, such as those that adhere to the ISCC Plus standard, typically contain a combination of raw materials derived from renewable and non-renewable sources.
The mass balance principle ensures that the percentage of renewable raw materials always remains constant, from sourcing to finished product.
Michael Costello, group director of ESG at Stahl, said: "The mass balance certification verifies that Stahl's manufacturing sites adhere to the highest standards of traceability, which is required to produce high-performance products containing raw materials derived from renewable and fossil sources."
"Certification also requires a transparent chain of custody for renewable raw materials used by the reporting company. This is essential to mitigate potential upstream supply chain risks, making ISCC PLUS certification a key tool to promote greater supply chain transparency across the industry."
Lidia Martinez, ESG supply chain transparency manager at Stahl, said, "We are pleased to offer customers more mass balance certified products made from ISCC PLUS certified raw materials. Thanks to our recertification, we can continue to expand our range of mass balance certified polyurethanes made from bio-based, biocircular and circular raw materials."
"ISCC Plus recertifications are a guarantee of the quality and transparency of Stahl's mass balance sheet accounting. Alignment with ISCC Plus is one of the ways we support responsible sourcing of renewable raw materials by providing traceability testing."
