Lubrizol’s Turbhe site restored a recycling route for Sodium Hydrogen Sulphide (NaHS) after regulatory changes had pushed the material toward incineration.
Collaboration with regulators and Eureka Chemicals enabled the region’s first authorized NaHS recycling solution.
The approach reduced emissions from incineration, lowered disposal costs and turned a waste-management challenge into a more sustainable outcome.

A manufacturing byproduct called Sodium Hydrogen Sulphide (NaHS), at our Turbhe site was historically sold for reuse. In 2022, a regulatory change reclassified the material, requiring disposal through incineration—an expensive approach that would have resulted in a large amount of emissions, as well as significant investment.

Our Turbhe team worked quickly and collaboratively to restore a more sustainable disposal option. They partnered closely with regulators to once again allow recycling and supported Eureka Chemicals in becoming the region’s first authorized NaHS recycler.

With approvals secured and a new procurement agreement in place, NaHS could once again be reused instead of destroyed.

This solution delivered significant reductions in environmental impact by avoiding incineration and disposal costs.
