Nippon Shokubai Co., Ltd., working to achieve carbon neutrality by 2050, announces that it has obtained ISCC PLUS certification from the International Sustainability and Carbon Certification system (ISCC) for superabsorbent polymers (SAP) made by its subsidiary Nippon Shokubai Europe N.V. (NSE) located in Belgium from caustic soda produced using electricity generated from renewable energy. SAP, commonly used in disposable diapers, is mainly made from acrylic acid produced from propylene and caustic soda. In May 2021, NSE received ISCC PLUS certification (mass balance method) from ISCC for the production of SAP utilizing acrylic acid produced from biomass-derived propylene. It has now obtained ISCC PLUS certification for sustainable SAP made from caustic soda produced using electricity generated from renewable energy. Combining these certifications will contribute to reducing CO2 emissions throughout the product life cycle. Furthermore, Nippon Shokubai will establish a system that can supply bio-based/sustainable SAP in response to customer demand. In addition to these ISCC PLUS-certified SAP, Nippon Shokubai is engaged in the research and development of sustainable SAP that contribute to mitigating environmental impact, such as biodegradable SAP and recycled SAP from used disposable diapers. The company will contribute to realizing a sustainable society by promoting these research and development activities.
