Nippon Shokubai Obtains ISCC PLUS for Superabsorbent Polymers Derived from Caustic Soda Produced from Renewable Energy
TOKYO, Mar. 7, 2022 /Kyodo JBN-AsiaNet/ --

- Contributing to Reducing Environmental Impact of Disposable Diapers - 

Nippon Shokubai Co., Ltd. (hereinafter "Nippon Shokubai"), working to achieve 
carbon neutrality by 2050, announces that it has obtained ISCC PLUS 
certification from the International Sustainability and Carbon Certification 
system (ISCC) (*1) for superabsorbent polymers (SAP) made by its subsidiary 
Nippon Shokubai Europe N.V. (hereinafter NSE) 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 (*2)) 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.

Notes:
(*1) ISCC (International Sustainability and Carbon Certification): ISCC is one 
of the world's largest certification organizations and widely recognized in 
Europe and many other parts of the world. It has a track record of over 4,000 
certifications in more than 100 countries for sustainable raw materials like 
biomass and waste plastics as well as recyclable products.

(*2) mass balance method: When biomass-derived raw materials and 
petroleum-derived raw materials are mixed, the ratio of the biomass-derived raw 
materials used is assigned as the biomass ratio of the specific end product. 
For example, if 30% of the propylene used in the production of acrylic acid and 
SAP is bio-based propylene and the rest is petroleum-based propylene, the mass 
balance method can be applied to allocate 30% of the bio-based propylene to 
SAP. Therefore, biomass-derived and petroleum-derived raw materials can be 
manufactured up to completion of the final product without distinguishing 
between them, and the extent of the contribution to the reduction of CO2 
emissions during the life cycle of the product can be shown.
