Nippon Shokubai Co. (Osaka, Japan) announced that it has obtained ISCC PLUS certification from the International Sustainability and Carbon Certification system (ISCC)for superabsorbent polymers (SAP) made from caustic soda produced using electricity generated from renewable energy by its subsidiary Nippon Shokubai Europe N.V. (hereinafter NSE).
SAP commonly used in disposable diapers are 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 the reduction of CO2 emissions throughout the product life cycle. Furthermore, Nippon Shokubai will establish a system that can supply bio-based/sustainable SAP in response to client demand.
In addition to these ISCC PLUS-certified SAP, Nippon Shokubai is engaged in the research and development of sustainable SAP that contribute to the reduction of environmental impact, such as biodegradable SAP and recycled SAP from used disposable diapers.
