A major breakthrough in tackling both waste plastic and aviation emissions has been marked with the opening of the world’s first waste plastics to Sustainable Aviation Fuel (SAF) pilot facility at Discovery Park.
Dedicated to converting hard-to-recycle waste plastics into SAF, the new Sustainability Innovation Centre is operated by Clean Planet Technologies. The Centre is set up to research and develop new technologies to deal with non-recyclable plastic waste, beginning with conversion into jet fuel.
The UK creates 5 million tonnes of waste plastics each year, 80% of which cannot be recycled, such as carrier bags and food packaging film. Globally the world’s commercial aircraft consume between 7 and 8 million barrels of jet fuel per day, equivalent to 7-8% of total global daily oil demand.
Dr Andrew Odjo, Chief Executive Officer at Clean Planet Technologies, said: “Our process first heats the waste plastic with a chemical reaction to turn it into a liquid, rather than burning it. This is then treated with our patented process to remove impurities and create SAF that meets stringent commercial aviation specifications.
“Every day, around 100,000 commercial flights operate globally while approximately 30,000 tonnes of plastic enters the ocean. That’s the equivalent of us dumping 2,000 garbage trucks full of plastic into the world’s oceans, rivers, and lakes every single day. Our pilot facility will demonstrate this waste can be turned into a premium product with a quantifiable commercial demand, as well as reducing the lifecycle carbon footprint of the aviation industry. We monitor how much energy the process uses, and overall, it cuts the lifecycle greenhouse gas emissions by more than 70% compared to traditional fossil jet fuel.
“With currently less than 1% of global aviation fuel produced from sustainable sources, the scale of the environmental opportunity presented by our technology means the opening of our facility is an important step towards the UK’s ambition to support sustainable aviation.”
The pilot facility plays a critical role in bridging innovation and commercial development, integrating several stages into one single, controlled system optimised to transform hard-to-recycle plastics into SAF. It has been designed to support fuel and feedstock testing, validation and progression through the American Society for Testing and Materials (ASTM) qualification process, with financial support already in place from the Department for Transport-funded UK SAF Clearing House.
Chris Broom, Head of Business Development at Discovery Park, commented: “Kent is becoming a real hub for world-leading sustainable innovation, and this facility is a powerful demonstration of what’s possible when cutting-edge science meets the right environment to grow. The Sustainability Innovation Centre is a landmark moment — for Clean Planet Technologies, for Kent, and for the future of sustainable aviation.”
Over the past year, Discovery Park’s technical and engineering teams worked hand-in-hand with Clean Planet Technologies to deliver the new facility, co-ordinating the building and fit-out, plus procuring local consultants and contractors. The opening of the new facility was celebrated with an event on 24th April, which included key industry stakeholders and local Government attendees.
Dr. Katerina Garyfalou, Chief Operating Officer at Clean Planet Technologies, added: “The Sustainability Innovation Centre is set up to demonstrate our patented waste-plastics-to-SAF process at pilot scale, supporting fuel testing, validation and progression.
“The important thing is that our pilot facility will support the growth of others, helping the UK to meet its SAF mandate. UK government policy to decarbonise aviation fuel states that 2% of UK jet fuel demand must be SAF, increasing to 10% in 2030 and 22% in 2040.”
The key steps of the process are:
- Shredding: Waste plastics are pre-processed and shredded to a uniform size.
- Pyrolysis: The material is fed into one of the centre’s two pyrolysis units, with the largest capable of processing up to 1 ton of plastic per day. In this oxygen-free environment, the plastics are thermocatalytically converted into a synthetic crude oil. This melts the plastic, rather than burning it.
- Purification: Impurities and contaminants in the synthetic crude oil are removed.
- Distillation: The pyrolysis oil is transferred to a distillation unit, where it is separated into relevant fractions and optimised for upgrading into higher-value fuels.
- Upgrading: The fractions are then processed through Clean Planet Technologies’ patented hydroprocessing system, which uses hydrogen to further remove impurities, and transform the properties of the product to meet stringent SAF specifications.
- SAF product: The resulting ultra-clean, ultra-low sulphur fuel suitable for aviation use is sent for testing, blending and evaluation as part of the ASTM qualification pathway as SAF.
The fundamentals of the process (pyrolysis, purification, distillation and hydroprocessing) are all technologies which are currently used independently at commercial scale, meaning scaling up the process is not a challenge.
Clean Planet Group was founded in 2018 by Dr Andrew Odjo, Adel Louertatani, Bertie Stephens and Fernando Diamond.
CEO Bertie Stephens added: “Our pilot facility addresses two strategic challenges simultaneously: plastic waste management and aviation decarbonisation. By converting non-recyclable plastics – materials that would otherwise have gone to landfill or been incinerated – into low-carbon aviation fuel, the facility supports both circular economy objectives and the reduction of lifecycle greenhouse gas emissions.
“This pilot opens up new ways to make sustainable aviation fuel, just as existing feedstocks such as energy crops are becoming harder to secure. It also positions the UK as a leader in turning waste plastics into SAF, supports UK and European SAF targets and is helping clear the path to commercial-scale plants later this decade, and remove plastic waste from the environment.”
