Heathrow will kick-start a new trial turning unrecyclable plastic passenger waste – including food packaging and plastic film – into airport furniture, uniforms and lower-emission jet fuel by 2025.

  • In a UK first, Heathrow will trial new technology that could turn unrecyclable passenger waste into airport furniture, uniforms and alternative fuels

  • A new recycling unit, that could process up to 5,000 tonnes of non-recyclable plastic once scaled up, is being tested by the airport and could allow Heathrow to recycle 100% of its on-airport plastic waste

  • University College London and Sheffield-based company Catal will use funding from Heathrow’s Innovation Prize to set-up the new research and development (R&D) unit in the autumn, aiming to make the technology commercially viable by 2025

  • Heathrow calls on Government to consider changes to increase recycling of waste from aircraft

In a UK first, the airport will test a new recycling unit that will help solve the issue of waste from terminals and aircraft cabins for which there are limited commercial recycling options.

Currently at Heathrow, just close to 50% of airport and aircraft cabin waste is recycled. This is comparable with most local authorities despite the strict regulations in place for cabin waste from international flights to protect animal and plant health, which mean some waste must be sent for incineration or landfilled. The pilot plant, developed by Heathrow’s Innovation Prize winners Sheffield-based company Catal and UCL Dr Massimiliano Materazzi, has the potential to save up to 5,000 tonnes waste from incineration by turning it into its original oil state for recycling every year.

If successful, it will enable Heathrow to recycle all plastic waste from the airport where regulations permit. This technology could also help to salvage aircraft cabin waste should government review and adopt a more risk-based approach to regulations which currently mean tens of thousands of tonnes of recyclable products across UK airports have to be sent for incineration.

How the Innovation Prize winner’s proposal will work

Once the waste is refined using this new technology, the resulting oil will be collected and processed in a separate facility which makes use of renewable hydrogen to upgrade the oil into new generation, low-carbon products such as furniture and uniforms. It is estimated that between 5 and 8 kg of plastics oil will be produced for every 10 kg of waste handled each hour. Researchers say it’s also possible that this oil can be transformed into 2-3 kg/h of Jet A1-type sustainable fuel and will investigate further during the trial.

This autumn, Heathrow will help to kick start the R&D unit by awarding researchers a cash boost of £30,000. By 2025, Catal and Dr Materazzi plan to roll out commercial units to other airports.

To boost aviation recycling even further, Heathrow is calling on the government to consider changes to increase recycling of waste from aircraft cabins. Much more waste could be recycled by adopting a risk-based approach to regulation of international catering waste based on recommendations from IATA, the global airline trade association. This would help airlines avoid sending recyclable waste to incineration.

“Unrecycled cabin and airport plastic is one of the less highlighted problems in the aviation industry today – but with tens of thousands of tonnes of it produced by UK passengers every year, it is an important area that we need to tackle. That’s why we’re helping to fund this R&D project which could make Heathrow the first UK airport to be able to recycle all plastic waste generated at the airport.”

Matt Gorman, Heathrow Sustainability and Environment Director

Heathrow Sustainability and Environment Director Matt Gorman, said, “Unrecycled cabin and airport plastic is one of the less highlighted problems in the aviation industry today – but with tens of thousands of tonnes of it produced by UK passengers every year, it is an important area that we need to tackle. That’s why we’re helping to fund this R&D project which could make Heathrow the first UK airport to be able to recycle all plastic waste generated at the airport.”

“Coupled with new regulations from Government on processing cabin waste, it would create a step-change in how airports across the UK manage plastic waste – giving passengers the confidence to travel knowing their plastics are sorted.”

Speaking on behalf of the winning team, Dr Materazzi from UCL, said, “Currently airline passengers alone generate approximately 6 million metric tonnes of waste each year, most of which goes to landfill or incineration because it cannot be appropriately treated and then recycled. Our concept has the potential to turn this problem on its head. We are excited to partner with the UK’s biggest airport and look forward to making a real sustainable impact across the aviation industry and beyond.”

More about the Innovation Prize and Heathrow’s Centre of Excellence…

The Innovation Prize forms part of Heathrow’s Centre of Excellence for Sustainability and the airport’s sustainability strategy – Heathrow 2.0. The Centre’s mission is to facilitate the research and development of innovative solutions to accelerate the era of sustainable flight. Currently the Centre’s focus is on solving some of its initial innovation challenges with its growing network of academic partners, covering topics as wide ranging as climate change, circular economy and community wellbeing.

Beating other applications from small to medium sized businesses across the UK, company Catal and UCL Professor Massimiliano Materazzi were found to have the best solutions which could solve some of the sustainability challenges facing airports and the aviation industry more widely.

Entries were invited to focus on three areas as part of Heathrow’s Centre of Excellence for Sustainability work on accelerating the arrival of sustainable flight: travelling to the airport carbon-free; getting ready for sustainable propulsion; and negative emissions at or near the airport.

Finalists pitched to a senior judging panel including Matt Gorman, Heathrow’s Director of Sustainability & Environment, Katherine Leahy, Heathrow’s Director of Airport Operations, Chris Annetts, Heathrow’s Retail Director, Fiona Carleton, Future Heathrow Director, plus guest judges Jonathan Counsell, IAG’s Director of Sustainability and Valentin Alfaya, Health&Safety, Quality & Environment Director at Ferrovial.

Runners up in this year’s Innovation Prize:

  • EB Charing – digital clean air zone
    EB Charging proposed creating a virtual Clean Air Zone around Heathrow by installing & using existing telematics in selected fleets, including contractor fleets, taxis, Heathrow landside and airside vehicles. Once a vehicle enters the defined zone their behaviour is tracked and can be rewarded or penalised, such as a financial penalty for idling >5mins. This smart system raises the case for fleets to use EVs and provides incentives for environmentally friendly behaviours, to solve a multitude of challenges including air quality and noise.
  • Fuel Matrix Ltd – cabin load measurement
    Fuel Matrix proposed to demonstrate how a simple weighing device could accurately capture the weight of passengers, crew and all hand baggage in order to optimise the aircraft fuel load for a specific flight. Their innovative FMS Cabin Load Measurement and Fuel Load Optimiser could contribute a significant reduction in emissions at and around the airport as well as reduce CO2 emissions from the flight itself.
  • Magway Ltd – hyperloop for goods
    Magway is a disruptive and sustainable transportation technology which could enable small freight, retail goods and even dry waste move between landside and airside locations through small diameter pipes. This solution would reduce congestion and protect local air quality as the fully autonomous system produces zero emissions and it would take delivery vehicles off the road.
  • Alchera – “AI” surface access data aggregation
    Alchera proposed to leverage their existing AI-based software platform, Alpha, to provide robust, real-time mobility data in order for Heathrow to determine how best to nudge passenger behaviours away from cars, towards more sustainable forms of transport.
