KLK OLEO and Sustainability
At KLK OLEO, we believe that sustainable solutions deserve the highest level of attention across all markets. That’s why we are proud to be among the leading innovators when it comes to developing and delivering sustainable alternatives.
As a founding member of the Roundtable on Sustainable Palm Oil (RSPO), KLK OLEO is committed to responsible sourcing and production. Since 2023, KLK OLEO offers sustainable surfactants for technical applications using bio-circular ethylene oxide (EO) and propylene oxide (PO).
We are delighted to introduce the Hedjuvan Circular product line – a new generation of sustainable excipients designed for the pharmaceutical industry. These innovative ingredients reduce Product Carbon Footprint (PCF) across the pharmaceutical supply chain, supporting more climate-conscious drug manufacturing.
What is Bio-Circular Ethylene – and Propylene Oxide?
The Hedjuvan Circular range employs bio-attributed EO derived from renewable, bio-circular sourced raw materials instead of fossil based ones.
The recycled biogenic input is precisely tracked and corresponds to the certified bio-circular EO/PO quantity. Quality and performance match conventional materials, ensuring broad compatibility with existing pharmaceutical applications.
Thanks to ISCC PLUS certification, it is ensured that the EO and PO used for the production is verifiably derived from bio-circular sources, supporting transparent and traceable sustainability across the entire value chain.
