A technology that does what no one else had managed

The only patented process that removes sulfur from HSFO without blending.

The Rigby Process®

The Rigby Process® was born from a very simple question that nobody had taken seriously: what if instead of finding a new fuel, we simply removed the sulfur from the one that already exists?

That's exactly what we do — and the result is a patented, proven process that converts HSFO into fully compliant VLSFO or ULSFO, without blending, without compromise.

Our Environmental Impact

The shipping industry is responsible for 16% of global SOx emissions and 14% of NOx emissions. These aren't abstract numbers — they translate directly into respiratory disease, ocean acidification, and climate impact.

-80% SOx · -60% NOx

The Rigby Process® delivers those reductions on every single barrel we process. Not as a target. As a result.
