Nippon Shokubai Obtains ISCC PLUS for Bio-based Superabsorbent Polymers
OSAKA, Japan, July 12, 2021 /Kyodo JBN-AsiaNet/ --

- To Contribute to Reduction in Environmental Impact of Disposable Diapers -

Nippon Shokubai Co., Ltd., has obtained biomass certification for 
superabsorbent polymers produced by its subsidiary Nippon Shokubai Europe N.V. 
(hereinafter "NSE") from ISCC (*1) (International Sustainability and Carbon 
Certification), with the aim of achieving carbon neutrality by 2050.

SAP, the key material for disposable diapers, is mainly made from acrylic acid 
produced from propylene. NSE produces both acrylic acid and SAP. NSE has 
recently obtained ISCC PLUS certification (mass balance method (*2)) from ISCC 
for the production of SAP utilizing acrylic acid produced from biomass-derived 
propylene. NSE will establish a system to supply bio-based SAP in response to 
customers' requests. The quality of bio-based SAP is equivalent to that of 
conventional petroleum-derived products, and the use of bio-based SAP will 
contribute to the reduction of CO2 emissions throughout the product life cycle.

In addition to bio-based SAP, Nippon Shokubai is engaged in the research and 
development of sustainable SAP that contributes to the reduction of 
environmental impact, such as biodegradable SAP and recycled SAP, which is 
separated from used disposable diapers and restored to almost the same level of 
functionality as new ones. 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 is widely recognized in 
Europe and other parts of the world. It has a track record of more than 4,000 
certifications in over 100 countries for sustainable raw materials, such as 
biomass and waste plastics, and 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 contribution to reducing CO2 emissions during 
the life cycle of the product can be shown.
