Envalior’s Jhagadia and Porto Feliz sites certified to ISCC Plus standard

With Jhagadia in India and Porto Feliz in Brazil, two more of Envalior’s 18 production facilities have been certified to the International Sustainability and Carbon Certification (ISCC) Plus sustainability standard. As a result, these sites can now market ECO compounds of the Durethan® (polyamides 6 and 66) and Pocan® (PBT) brands, for which the content of bio-based and/or circular raw materials is rendered completely transparent for customers thanks to mass-balance methodology.

“This enables our local customers to establish supply chains whose sustainability is traceable throughout the entire value chain,” said Dr. Günter Margraf, Director Sustainability at Envalior. “In addition, this certification represents yet another step taken by our company toward climate neutrality and closed, resource-conserving material cycles.” The company is also preparing for the ISCC certification of its plants in Hamm-Uentrop in Germany and Gastonia in the USA. 

Transparant sustainability

The ISCC standard was developed for purposes including assessing the sustainability requirements of the EU Renewable Energies Directive and has since become an established fixture in the global chemical industry. Attached to the standard is mass-balancing, which enables fossil-based and alternative raw materials to be used together in production but separated using a special accounting method. This means that material quantities can be tracked along multi-stage production processes, ultimately allowing the amount of sustainable material in the end product to be precisely calculated and communicated to customers transparently and accurately. 

No change to production processes thanks to drop-in solutions

It is important that the bio-based and circular polymer raw materials are chemically identical to the completely fossil-based raw materials that are normally used. Plastics are therefore produced that exhibit the same quality as well as the same mechanical and processing characteristics as their fossil-based counterparts. In other words, plastics that meet the same technical specifications and certification standards.

“Our customers can use these sustainable compounds simply as ‘drop-in’ solutions in their existing, already-optimized facilities,” said Margraf. “Their production processes and workflows do not need to be altered, nor does the processor need to have these sustainable materials checked and approved again by their customer.” 

Numerous sites worldwide already ISCC-certified

Numerous Envalior production sites have already been awarded ISCC Plus certification, including Kallo and Lillo in Antwerp, Krefeld-Uerdingen in Germany, Emmen, Geleen, and Beekerveld in the Netherlands, and Jiangsu in China. The upcoming certification in Hamm-Uentrop is for DuBay Polymer GmbH, a joint venture between Celanese and Envalior specializing in the manufacture of polybutylene terephthalate base resin and associated compounds.
