The newly granted patents follow the UK patent first awarded in 2022 and extend the global reach of CPTech’s proprietary method for converting low-grade, highly variable pyrolysis oils into ultra-low sulfur fuels and circular petrochemical feedstocks – a breakthrough that improves stability, reduces impurities, and enables far more efficient downstream upgrading.
Originally developed for ultra-low sulfur diesel, naphtha, and marine fuels, CPTech’s multi-stage upgrading process – fractional condensation, tailored hydrotreating, and precision distillation – is now a central enabling technology inside the company’s plastics-to-SAF (P2SAF) programme.
This approach allows CPTech to transform mixed waste plastics into an ultra-clean product suitable for further refining into SAF.
“The fundamentals matter,” said Dr Andrew Odjo.“Reliable, consistent upgrading of plastic-derived oils is essential if we are to diversify SAF feedstocks. Securing these patents strengthens our ability to scale this work globally.”
By securing patent protection in two major energy markets – including the US and the Kingdom of Saudi Arabia – CPTech strengthens its position to license, develop, and protect its technology across jurisdictions central to global fuel production.
