Ben Gibbons and his colleagues at Circular11 are developing ways to add value to hard-to-recycle light plastics. They take packaging, and turn it into a lumber-equivalent, suitable for long term use as post and rail fencing. But to maintain tight loops of circularity, they needed to understand the supply chain they were targeting.

National Highways designed a programme to help innovators like Circular11 scale their ideas. The sustainable plastic re-use business, alongside three other start-ups, went all the way through to the final phase—live trials on the UK’s strategic roads network—of this Acceleration Low Carbon Innovation programme, organised with the help of the Connected Places Catapult.

The accelerator was awarded Gold Champion in the Net Zero category of the Engineering Matters Awards. In this episode, we learn about the challenges facing SMEs as they try to enter the complex and highly regulated roadbuilding sector. We hear how the programme was designed to bring together SMEs, established contractors, and roadbuilding experts, helping scale sustainable innovations, in a way that is ripe for emulation by other major clients.

Entry for the 2026 Engineering Matters Awards is now open.

Worldwide, water is in short supply and high demand, with very real consequences for human health and security. Many countries struggle to maintain aging networks, meaning that more than 20% of clean water is lost before it reaches the customer. New industries, like data centres, are adding to demand, as they use water for cooling.

In this episode, we look at the work of FIDO Tech, which is using AI and acoustics to identify leaks. The idea of listening for leaks is not new. Traditionally, water company engineers would use a steel rod with an ear cup to listen to water flowing through a pipe. But this is a skilled job, which takes time and staff resources to perform.

FIDO first developed its process as part of an innovation accelerator backed by United Utilities. Bringing the product to market demanded careful thought about physical sensor design, and rigorous training of their AI. In a four week trial with Thames Water, their system was able to work through 45,000 historic recordings, and identify leaks with more than 90% accuracy. Now, the company is developing their system to allow for real time detection of leaks, across water networks.

On the coast of rural Cumbria, in England’s northeast, a once-secretive nuclear site is transforming its legacy by investing in the engineers of tomorrow. Sellafield, known historically for producing weapons-grade plutonium and nuclear energy, has now begun the 100 year process of decommissioning. At the Sellafield Engineering & Maintenance Centre of Excellence, engineers research and develop new technologies for the nuclear industry and engage with the local community. 

As the 2025 Community Gold winners at the Engineering Matters Awards, the team at Sellafield has been recognised for their exceptional outreach to local schools, students, and SEND communities, using engineering to inspire and empower the next generation. In this episode, we explore their work,

Claire O’Connor, the social impact and community lead and Angela Broggins, work experience lead from the Centre of Excellence, along with Jo Hedley from Branthwaite Academy, explain how their unique, inclusive programmes give students not only technical skills but also the confidence to envision futures in STEM. Whether it’s hands-on robotics with primary pupils, bespoke work experience for neurodiverse students, or creating pathways into apprenticeships and employment, this team is reshaping what access to engineering education can look like.

Listeners will learn how the Sellafield Centre of Excellence has shifted the narrative around nuclear engineering, from secrecy to openness, from decommissioning to development. We uncover how strategic, long-term community engagement can spark real change, and how tailored learning has already helped hundreds of young people find their place in the engineering world.

The past months have seen a shift in international trade, of a scale not seen for decades. New US tariffs have created uncertainty for investors, and promise to spark a global trade war. While these new challenges to cross-border trade are unique, recent years have seen another shift in industrial policy, particularly in the UK, with leaders on both sides of the political divide emphasising a pro-growth, abundance agenda.

With such pressures on existing supply chains, and renewed attention to growth and productivity, can manufacturers still aim for decarbonisation? In this episode, first aired in March 2023, we present an idea that promises to boost growth, while meeting climate goals and protecting local supply chains. 

Sam Turner, Net Zero champion for the UK’s High Value Manufacturing Catapult, proposes a new approach: not offshoring, but ‘greenshoring’. The strategy would see countries competing not just on their ability to supply cheap labour and materials, but on their ability to reduce carbon emissions and other environmental harms.

It’s an approach that has been adopted by Frog Bikes, a manufacturer based in the UK’s Bike Valley, a regional cluster of businesses that aims to develop bicycle manufacturing in the country. 

But the company has struggled to find the data it needs to prove its ability to compete in terms of carbon costs. Doing this will require the development of new carbon accounting tools, and of standards that allow them to be validated.

The rise of AI and machine learning promises a revolution in how we live and work. Expert reasoning and mundane tasks will be completed for us in the cloud. But the cloud is not ethereal or abstract. It is a globe spanning mass of physical infrastructure. Enabling this transformation will demand a huge expansion in data centre construction.

Data centres house the processing and computing power that the world relies on. Investors have pledged trillions for their construction. But their costs are environmental, as well as financial. From energy, to water, to materials, data centres require a lot of resources to build and operate. By 2030 the IEA (International Energy Agency) estimates that worldwide data centres will consume 1,000 terrawatt hours of electricity. Today an average data centre uses 300,000 litres of water a day. 

However sustainability in the industry is improving. In this episode, Josh Parker, head of sustainability for Nvidia, explains how improvements in chip design and accelerated computing have led to massive gains in efficiency over the last ten years, doing the same AI workload uses 100,000x less power. Sustainability gains go beyond operational energy use. As Professor Deborah Andrews highlights, e-waste and water usage are key issues the industry must address. And, as Damien Dumestier explains, the scale of this new sector will, perhaps, push innovation all the way into space.

In this episode we explore what the industry is doing to become more sustainable, from improving energy efficiency, building data centres in novel and remote locations and by using AI itself to improve sustainability across industries.

This February, with the flick of a switch, there was a vast shift of power on Europe’s borders. The Baltic states’ electrical grids, built in the 1960s while these countries were forcibly incorporated into the Soviet Union, had been under the control of Moscow. In one weekend, the transmission system operators in Latvia, Lithuania, and Estonia, working with partners in Poland and across continental Europe, disconnected from Russia, and synchronised their systems with those of their neighbours to the West.

While the switchover took only a weekend of testing, and synchronisation occurred in an instant, the project was decades in the making. For the Baltic nations, the threat of Russian aggression had been clear as early as 2007, when Estonian institutions suffered a massive cyber attack. But securing the political and financial support of their neighbours would take careful diplomacy.

The €1.6bn project would also require the deployment of cutting edge grid systems. These included synchronous condensers, needed to add inertia to grids as they move towards widespread use of renewable energy; new connections with the continental European grid; and investments in new high voltage lines and battery storage.

In this episode, three of the leaders of this project, from Lithuania, Estonia, and Poland, share how they made the case for this investment in European energy security, and the work needed to upgrade grid systems across the region. They describe the excitement of the moment when synchronisation occurred, and the benefits to countries across Europe of a grid system that is secure and ready for the energy transition.

Seagrass meadows are the engineers of the marine ecosystem. They provide habitats, support biodiversity, prevent coastal erosion and sequester carbon dioxide. For this reason Italy has embarked upon a world leading project to map these coastal ecosystems at a national scale, enabling it to plan protection and restoration measures that will improve ocean health and meet legislative targets. 

This is only possible thanks to recent advances in coastal mapping technology and the sophisticated integration of state of the art data collected by a range of sources from satellite sensors, lidar and multibeam echosounders to hyperspectral cameras on autonomous underwater vessels.

We can reuse and retrofit buildings to extend their lifespans, and reduce their embodied carbon impact. But some structures may not be suitable for full reuse: some will have reached the end of their safe life; others will have no viable reuse; and some retrofit projects may require partial dismantling to reduce loadings on the original structure.

But demolition or disassembly does not need to mark the end of the life of building materials. With care and planning, these can be dismantled and used anew. Around the UK, we see centuries old pubs and homes built using recovered timbers, from ships and structures. But this is just a starting point for materials reuse.

In this episode, a follow-up to episode 315 Renewing the world, without costing the planet, we learn why architects and engineers should plan for materials reuse, from design through to demolition or disassembly. We examine how different materials can be reused. And we look at the development of trading platforms that enable the use of reclaimed materials at scale.

Quantum mechanics has transformed our understanding of reality, but how did we get here? In this episode, we celebrate the International Year of Quantum, marking 100 years since the birth of this groundbreaking field. From the fierce debates between Einstein and Bohr to the mind-bending implications of superposition and entanglement, we explore how quantum mechanics has reshaped modern science and technology. 

Dr. Paul Cadden-Zimansky, Associate Professor of Physics at Bard College, a physicist and science communicator, untangles the complicated history and science behind quantum mechanics. With years of experience bridging complex scientific ideas and public understanding, Paul takes us on a journey through the milestones and debates that defined quantum theory in the early years of its development.

The episode explores how quantum mechanics emerged from early 20th-century experiments, the heated philosophical battles that shaped its interpretation, and why its implications continue to challenge our understanding of reality. Paul explains how quantum mechanics has shaped groundbreaking technologies throughout the 20th and early 21st century. We learn how quantum theory is fuelling today’s cutting-edge technologies, from quantum computing to secure communications.
