Clean Planet Technologies (CPTech), a subsidiary of the Clean Planet Group, has announced the formal patenting of its core pyrolysis-oil upgrading process in both the United States and Saudi Arabia. This development expands the intellectual property protection of CPTech’s breakthrough technology, which is a key component of the company’s Plastics-to-SAF (P2SAF) programme.
The newly granted patents add to the UK patent that was first awarded in 2022, increasing the global reach of CPTech’s proprietary method for converting low-grade, highly variable pyrolysis oils into ultra-low sulphur fuels and circular petrochemical feedstocks. This technology improves stability, reduces impurities, and allows for more efficient downstream upgrading.
CPTech’s multi-stage upgrading process, which includes fractional condensation, tailored hydrotreating, and precision distillation, was originally developed for ultra-low sulphur diesel, naphtha, and marine fuels. It is now a central enabling technology within the P2SAF programme, allowing CPTech to transform mixed waste plastics into an ultra-clean product suitable for further refining into sustainable aviation fuel (SAF). This approach was recently showcased by CPTech CEO Dr. Andrew Odjo at the SAF Global Summit, where he presented the UK’s first Plastics-to-SAF pathway to over 500 policymakers, airlines, and industry leaders.
Dr. Odjo stated, “The fundamentals matter. 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.”
The timing of the patents aligns with a surge in momentum for CPTech, as the company recently announced the arrival of equipment for its first P2SAF pilot facility, set to be commissioned in Q1 2026. This will be the first real-world demonstration of the SAFe-P2SAF platform, marking the transition of the technology from stage-presentation to steel-in-the-ground deployment.
With UK and EU SAF mandates coming into force, increasing pressure on bio-based feedstock supply chains, and growing airline commitments to decarbonisation, alternative circular feedstocks such as waste plastics are gaining strategic importance.
By securing patent protection in two major energy markets – the United States and the Kingdom of Saudi Arabia – CPTech is positioning itself to license, develop, and protect its technology across jurisdictions that are central to global fuel production.
CPTech’s patented process addresses long-standing challenges associated with raw pyrolysis oil, which is typically unstable, oxygen-rich, metal-laden, and unsuitable for use in refineries or engines without extensive upgrading. By increasing stability, controlling variability, and removing sulphur, nitrogen, and other contaminants, the technology produces a cleaner, more predictable intermediate oil – exactly what is required for advanced aviation-grade upgrading.
Dr. Odjo commented, “This patent was never just about improving diesel. It was about unlocking a pathway for waste plastics to become genuinely circular. Today, that pathway leads directly into SAF.”
With further announcements expected later this year, the expanded patent protection sends a clear signal: CPTech is not only innovating in the lab and on the stage – it is securing the legal and commercial underpinnings needed to scale plastics-to-fuel production globally.
Dr. Katerina Garyfalou, COO of Clean Planet Technologies, stated, “Turning difficult waste into strategic low-carbon fuels requires more than good science. It demands certainty, protection, and the ability to scale with confidence. These patents help us do exactly that.”
Clean Planet Technologies (CPTech) is a subsidiary of the Clean Planet Group, dedicated to developing proprietary technologies that enable the sustainable use of plastics and the reduction of carbon emissions. Its portfolio includes innovations in Plastics-to-SAF, Plastics-to-Hydrogen, Plastics-to-Monomers, and containerized pyrolysis systems (CPS²). CPTech’s technologies support the circular economy by transforming low-value waste into high-value, low-carbon fuels and chemicals.
