One problem. One solution. One process.
The Rigby Process® converts high-sulfur marine fuel into IMO 2020 compliant VLSFO or ULSFO. No blending. No workarounds. Just a patented process that works.




We remove the sulfur. You keep the fuel.
The Rigby Process® takes your HSFO and converts it directly into compliant VLSFO (0.5% S) or ULSFO (0.1% S) — preserving the energy density and properties your engines were designed for.
No distillate blending. No cat fines. 96% mass retention.
-80% SOx emissions -60% NOx emissions 96% Mass retention 99% Product utilization
The fuel that powered the global fleet is no longer permitted.
Since January 2020, HSFO with 3.5% sulfur content cannot be used as marine fuel without a scrubber. Refineries and terminals are sitting on surplus residual material with limited market value. Ship operators need compliant fuel that their engines are actually designed for.
The industry needed a real solution — not a blend, not a compromise.
How it works for you.
You supply 20,000 barrels per day of HSFO. We process it.
You receive 96% back as market-ready VLSFO, plus 2% as recovered sulfur and 1% as naphtha.
You pay a tolling fee — and gain significantly more value than the feedstock was worth before.
One long-term contract. Minimum 20 years. Built so both sides win.
