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 SAF (SAF) pilot facility. Operated by Clean Planet Technologies, the new Sustainability Innovation Centre is located at Discovery Park in Sandwich, Kent. The facility is dedicated to researching and developing new technologies to process non-recyclable plastic waste, beginning with its conversion into jet fuel.

The pilot facility addresses the growing problem of hard-to-recycle waste plastics and the environmental impact of the aviation industry. According to the company’s press release, the UK alone creates 5 million tonnes of waste plastics each year, 80% of which cannot be recycled and is treated as waste. Meanwhile, the world’s commercial aircraft consume 7 to 8 million barrels of jet fuel a day, with less than 1% currently produced from sustainable sources.

Transforming Waste into Sustainable Aviation Fuel

The new pilot facility integrates several stages into a single, controlled system optimized to transform hard-to-recycle plastics into SAF. The process begins with shredding the waste plastics to a uniform size, followed by pyrolysis, where the material is thermocatalytically converted into a synthetic crude oil in an oxygen-free environment. This melts the plastic rather than burning it.

After purification to remove impurities and contaminants, the pyrolysis oil undergoes distillation to separate it into relevant fractions. These 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. The resulting ultra-clean, ultra-low sulfur fuel is sent for testing, blending, and evaluation as part of the American Society for Testing and Materials (ASTM) qualification pathway.

Reducing the Aviation Industry’s Carbon Footprint

The environmental impact of this technology are significant. According to Clean Planet Technologies, the process cuts lifecycle greenhouse gas emissions by more than 70% compared to traditional fossil jet fuel.

“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,” said Dr. Andrew Odjo, Chief Executive Officer at Clean Planet Technologies.

Dr. Odjo also highlighted the scale of the opportunity, noting that 100,000 commercial flights operate globally every day, while 600,000 tonnes of non-recyclable waste plastics enter the environment. The pilot facility aims to demonstrate that this waste can be turned into a premium product with quantifiable commercial demand.

Supporting UK and Global Sustainability Goals

The Sustainability Innovation Centre plays a critical role in bridging the gap between innovation and commercial development. It has been designed to support fuel and feedstock testing, validation, and progression through the ASTM qualification process. The facility has already secured financial support from the Department for Transport-funded UK SAF Clearing House.

We note that the fundamentals of the process,pyrolysis, purification, distillation, and hydroprocessing,are all technologies currently used independently at a commercial scale, which suggests that scaling up the integrated process will not present a significant challenge for the company.

Meeting the UK’s SAF Mandate

The opening of the pilot facility is an important step toward the UK’s ambition to support sustainable aviation and meet its SAF mandate.

“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,” added Dr. Katerina Garyfalou, Chief Operating Officer at Clean Planet Technologies.

UK government policy to decarbonize aviation fuel states that 2% of UK jet fuel demand must be SAF, increasing to 10% in 2030 and 22% in 2040.

Addressing Dual Strategic Challenges

Clean Planet Group, founded in 2018, views the new facility as a solution to two pressing global issues. By converting non-recyclable plastics,materials that would otherwise go to landfill or be incinerated,into low-carbon aviation fuel, the facility supports circular economy objectives.

“Our pilot facility addresses two strategic challenges simultaneously: plastic waste management and aviation decarbonisation,” said Clean Planet Group CEO Bertie Stephens.

Stephens noted that the pilot opens up new ways to make sustainable aviation fuel at a time when 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, supporting UK and European targets, and helping clear the path to commercial-scale plants later this decade.

This article is based on an official press release from Lockheed Martin.

The X-59 quiet supersonic research aircraft is officially pushing its limits. According to a recent press release from Lockheed Martin, the experimental jet has entered its envelope expansion campaign, a critical testing phase where the aircraft is flying higher, faster, and farther than before.

Developed in partnership between NASA and Lockheed Martin’s Skunk Works division, the X-59 aims to revolutionize commercial aviation. By replacing the disruptive sonic boom with a quieter “sonic thump,” the program hopes to pave the way for regulators to lift the long-standing ban on overland supersonic commercial flights.

The latest updates from the manufacturers indicate that the aircraft has successfully completed nine flights, accumulating 10.0 hours of total flight time. As the joint team pushes the aircraft toward its ultimate design speeds, we are watching closely to see if the dream of quiet supersonic travel can become a reality.

Advancing the Flight Test Campaign

Validating Speed and Altitude Profiles

The primary objective of the current envelope expansion phase is to rigorously validate the X-59’s performance across a diverse range of speed and altitude profiles. According to the Lockheed Martin release, the flight test team is evaluating the aircraft at both high-and-fast and low-and-slow test points to ensure structural and aerodynamic stability.

Recent milestones highlight the rapid pace of this testing. The company reports that the X-59 has reached an altitude of approximately 43,000 feet and achieved speeds of roughly Mach 0.95. The longest single flight to date has lasted about 1.7 hours, demonstrating the aircraft’s growing reliability following initial maintenance and software upgrades.

The Path to Mach 1.4

As the envelope expansion continues, the joint NASA and Lockheed Martin team plans to transition into supersonic speeds. The ultimate goal is to reach the aircraft’s specific design points: an altitude of roughly 55,000 feet and a cruising speed of Mach 1.4.

It is at these specific parameters that the X-59 is expected to generate its signature quiet supersonic thump. Achieving this milestone will be a pivotal moment for the program, proving that the unique aerodynamic shaping of the aircraft can successfully mitigate the shockwaves that typically cause a loud sonic boom.

Paving the Way for Commercial Supersonic Travel

A Vision for Faster Connectivity

The implications of the X-59 program extend far beyond experimental testing. The data gathered during these flights will eventually be used to deliver a scientifically validated low-boom specification to international aviation regulators.

Pat LeBeau, the X-59 program manager at Lockheed Martin Skunk Works, emphasized the broader mission of the project in the company’s press release.

“Every flight and every test point is a step toward a future where cities can be connected in a fraction of today’s travel time without the noise penalty that constrained the original supersonic era,” LeBeau stated.

AirPro News analysis

The progress of the X-59 is a highly encouraging sign for the future of high-speed commercial aviation. While the Concorde proved that supersonic passenger travel was technologically feasible, its economic viability was severely limited by noise regulations that restricted it to over-water routes.

If NASA and Lockheed Martin can successfully demonstrate that the X-59’s noise profile is acceptable to communities on the ground, we believe it could trigger a paradigm shift in regulatory frameworks. However, we note that the X-59 itself is not a prototype airliner, but rather a purpose-built data-gathering tool. Any future commercial supersonic airliners will need to incorporate these low-boom design principles while also addressing modern challenges related to fuel efficiency and emissions.
