The annual Materials Research Exchange event (Innovate UK) is a gateway into the world of materials innovation, featuring an exhibition, investor showcase, and cross-cutting seminars on technology transfer from the UK’s world-class research base.
It features a diverse range of materials from nanotechnology to biomaterials, textiles, polymers, metals, glass, and more. These materials are not just theoretical concepts but critical building blocks for real-world applications, including energy, space, construction, packaging, marine, automotive, and low-carbon technologies.
42T senior consultant, Rory Way, observes, "One really useful material being developed now is Algreen's 100% bio-based and biodegradable polyurethane, a variant which can be recycled and composted.
Derived from renewable biomass sources such as algae, corn starch, sugarcane, or cellulose, bioplastics are gaining popularity as an eco-friendly alternative to traditional plastics derived from fossil fuels. These materials are biodegradable or compostable, reducing the burden of plastic waste on the environment.

I also had a look at Henniker Plasma who were showcasing their plasma surface treatment, either for general improving of surface finishes or for allowing bonding of materials which are difficult to bond e.g. PTFE."
Rory adds, "Some of the presentations and talks included several which discussed changing the conversation from recycling towards reusing products instead - a more circular approach."
While recycling plays a crucial role in diverting waste from landfills and conserving resources, reusability represents a higher echelon of sustainability by minimizing the need for both recycling and disposal altogether.
Reusability focuses on designing products and packaging with durability and longevity in mind, allowing items to be used multiple times before reaching the end of their lifespan. This approach not only reduces the demand for new materials and energy required for recycling processes but also decreases overall waste generation.
Jake says, "Material recycling takes a lot of energy to achieve and/or inevitably degrades the material properties over time. This means the number of cycles a material can be recycled is limited. Also, the material produced can’t be used in all applications the virgin material can be used in - mostly, it’s the higher value applications that recycled materials can’t be used for.
Reusability is not only the reuse of the product for it’s original form and function for longer - it also includes repurposing materials without fully breaking them down in a recycling process. There is a lot of room for innovation and creativity in this space, for example, using cut sections of decommissioned wind turbine blades to create stylish public furniture such as bike shelters, bus shelters & footbridges."
Rory continues, "By encouraging a shift towards reusable alternatives, industries can significantly mitigate their environmental footprint while fostering a culture of conscious consumption and resource conservation."
Standout presentations included those from:
42T senior consultant, Jake Greer, continues: “I found PlantSea’s offering to be particularly fascinating – they’ve created and continue to develop customisable seaweed-based 'plastic' films. They are achieving some interesting material properties I've not seen from other seaweed-based films, such as higher levels of stretch in a stable film that can be used for storing liquids in.
They can also use the byproduct seaweed from the film manufacture to add to paper production. Adding significant percentages of recycled paper to paper production degrades the quality of the paper (due to the shorter fibre length). This is not an issue when adding seaweed byproduct pulp due to the unique properties of the seaweed, allowing for a high quality/strength paper products without the need for 100% virgin wood pulp.
It was also good to talk to FlexSea who offer an injection mouldable seaweed-based material range that biodegrades.

"Similarly, it was amazing to see what Glass Technology Services can do, from mimicking crystal properties for lasers all the way to soft, woven glass-fibre used for medical reconstruction implants that promote bone growth while the fibres are broken down and absorbed by the body.
As a whole, I was also glad to see materials coming out to combat the raft of plastic clothing being produced across the world, including:
Bio-based fibres derived from renewable sources or even agricultural/marine waste are gaining traction as alternatives to materials that are becoming scarcer (or more difficult or expensive to produce) due to constraints on water, energy and labour costs - for instance, conventional cotton and synthetic fibres. Bio-based materials often require fewer pesticides and water, and need less energy to produce."
Jake sums up, "As consumer awareness grows and regulatory pressures increase, the demand for sustainable materials will continue to rise. Businesses that embrace these trends not only contribute to a healthier planet but will also position themselves for long-term commercial success."
