Neste verifies MY Renewable Isoalkane™ as bio-based diluent for extracting metals


In Finland, Neste and Outotec have jointly verified the viability of applying Neste MY Renewable Isoalkane as a fully bio-based diluent for extracting metals in hydrometallurgical processes. The diluent is based on Neste’s NEXBTL technology and produced entirely from bio-based waste and residue raw materials.

Laboratory studies and pilot trials at the Outotec Research Center in Pori and Neste’s Technology Center in Porvoo, Finland, confirmed the high-level performance of the product for solvent extraction of copper, and it can be also used for other base metals.

Thanks to its renewable origins and being readily biodegradable, the bio-based diluent reduces environmental risks and has a remarkably smaller carbon footprint over its life cycle when compared to fossil equivalents. Moreover, Neste MY Renewable Isoalkane evaporates at a lower rate, which improves copper extraction efficiency and safety due to significantly reduced volatile organic compounds (VOCs). 

Neste MY Renewable Isoalkane is fully compatible with conventional fossil diluents at solvent extraction plants, and it can be introduced into the extraction process without any downtime.
