Nippon Shokubai Obtains ISCC Plus Certification for SAP – Nonwovens Industry Magazine

Nippon Shokubai, which is striving to achieve carbon neutrality by 2050, announces that it has obtained ISCC Plus certification from the International Sustainability and Carbon Certification (ISCC) system for superabsorbent polymers (SAPs) manufactured by its subsidiary Nippon Shokubai Europe NV (NSE) from caustic soda produced from electricity generated from renewable energy.

SAP, commonly used in disposable diapers, is primarily made from acrylic acid produced from propylene and caustic soda. In May 2021, NSE received ISCC Plus (mass balance method) certification from the ISCC for the production of SAP using acrylic acid produced from biomass-derived propylene. It has now achieved ISCC Plus certification for sustainable SAP based on caustic soda produced from electricity generated from renewable energy. The combination of these certifications will help reduce CO2 emissions throughout the product’s life cycle. In addition, Nippon Shokubai will establish a system capable of supplying bio-based/sustainable SAPs in response to customer demand.

In addition to these ISCC Plus certified SAPs, Nippon Shokubai is committed to the research and development of sustainable SAPs that help mitigate environmental impact, such as biodegradable SAPs and recycled SAPs from used disposable diapers. The company will contribute to the realization of a sustainable society by promoting these research and development activities.
