Heathrow Launches Groundbreaking Trial of Low Carbon Concrete, Targeting 50% Emission Reduction in Infrastructure Projects
- UK’s hub becomes one of the world’s first airports to trial use of lower carbon concrete
- Partnership between Heathrow, Jacobs, Ecocem, Cemex, Dyer & Butler and Ferrovial Construction will explore viability of ground-breaking lower carbon concrete in airport setting
- Heathrow serving as testbed for innovative green technology that could drastically reduce the sector’s carbon emissions
- Trial begins today with further exploratory testing of other products in the next year
London, UK, 2023-Aug-04 — /Travel PR News/ — Heathrow has kickstarted a ground-breaking new trial, exploring the viability of lower carbon concrete, which cuts emissions by 50% compared to a conventional concrete. The initiative followed Heathrow’s sponsorship of a PhD candidate at the University of Surrey who undertook three years of lab work to reach this point. The trial has been designed to test the concrete’s durability and longevity in a true to life airport setting and is one of the first of its kind at any airport in the world.
As part of Heathrow’s holistic sustainability strategy – Heathrow 2.0 – the airport is committed to reducing on the ground emissions as well as those in the air. With at least 6% of global carbon emissions each year linked to concrete production, Ecocem and Cemex’s innovative concrete solution has the potential to radically reduce the carbon output of infrastructure projects at the airport. The aim is for the trial’s findings to be used to set out a blueprint that other airports, keen to reduce carbon from all facets of their operation, can follow. This trial is the first of a number being planned that will test and trial other low carbon concrete materials on the market. It is intended that the outcomes of these trials can be used to reduce embedded carbon in a number of projects being delivered by Ferrovial Construction and Dyer & Butler at Heathrow.
The project, led by Jacobs and implemented by Cemex and Ecocem will see four different applications trialled in a pouring site located close to the control tower. These will replicate use in a range of typical airport infrastructure applications, including airfield pavements, encompassing runways and taxiways as well as reinforced pit cover slabs and other ancillary concrete types. With aircraft taking off and landing close to every 45 seconds at Heathrow, it is critical the concrete undergoes rigorous testing to ensure its strength and durability can withstand the pressures of the one of the world’s busiest airports.
Nigel Milton, Chief of Staff and Carbon at Heathrow said: “Heathrow is once again serving as a testbed for ground-breaking technologies, demonstrating global leadership with regards to sustainable travel. We’re committed to cutting carbon emissions on the ground as well as in the air and we’re delighted to be hosting one of the first airport trials in the world to test lower carbon alternatives. I hope that this trial will help radically transform the built environment at Heathrow in the years to come.”
Richard Moore, Europe Aviation Engineering Lead at Jacobs said: “Jacobs are delighted to have been the technical consultant on the Low Carbon Concrete initiative at Heathrow since its inception in 2018. Today’s trial is an exciting milestone in the development of lower carbon infrastructure solutions at the airport. It is the culmination of four years of research and planning towards these initial trials which will form the foundation of further work exploring other lower carbon products and materials. Testing the materials in a range of airport infrastructure applications, not just runway and taxiway pavements, allows us to maximise the opportunity to reduce embedded carbon in a wide variety of concrete types. Building on the success of today, we look forward to upscaling to usage in airfield projects being delivered by Ferrovial Construction, Dyer & Butler and other major programme partners across the airport.”
Mark Hill, UK National Sales Manager, Ecocem said: “Our technical solutions have long helped large scale infrastructure projects to reduce carbon emissions across Europe. Having the opportunity to partner with Heathrow airport on a project with huge potential in the UK and for the aviation sector is a testament to the innovation of our products and team. We look forward to working with Heathrow and our other partners to begin this trial.”
Richard Kershaw, Technical Manager at Cemex said: “Cemex is renowned across the construction industry for its commitment to providing customers with more sustainable concrete solutions. We were the first supplier in the UK to launch a net-zero concrete product, making us ideally situated to support Heathrow with their lower carbon concrete trial. We hope this trial will prove successful and demonstrate to the aviation sector the opportunities available to cut emissions during their development projects.”
Simon Wright, Regional Manager at Dyer & Butler, said: “As a trusted partner to Heathrow, we’re proud to be collaborating on this project to pioneer carbon reduction in the aviation industry. Our technical delivery team is excited to be involved in delivering this emerging technology. Dyer & Butler is committed to helping Heathrow work towards its net-zero targets on this, and future innovations.”
Juan Pablo Perez, UK Airports & Civils Director, Ferrovial Construction said: “Our strategy at Ferrovial Construction is to deliver low carbon concrete solutions across our different projects worldwide. As part of our UK project portfolio, we are actively working with Heathrow, Jacobs and Cemex to achieve a low CO2e concrete mix. During the previous Heathrow framework (Q6), we achieved a reduction on carbon emissions in PQ mixes. We have taken that progress and development and are driving further reduction at H7 by exploring and trialling new technologies. As the first company at Heathrow to gain PAS2080 certification for Carbon Management, we have been able to deliver projects with the lowest Pavement Quality Concrete CO2e compliant with the high standard specification at the airport. We are excited to continue working with Heathrow, Jacobs and Cemex to drive the sustainable concrete development agenda in full support of Heathrow 2.0.”
