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.
