Rethinking Materials Summit, London, May 16-17  

With consumers and regulators more focused on the materials we use and how they are disposed of than ever before, innovators are revolutionising materials for consumer goods, which includes packaging, textiles, non-wovens, and durable goods, as well as approaches to waste management.

14 start-ups offering scalable solutions and technologies to shake up the CPG, textiles, durable goods, and packaging value chains will take to the stage at the Rethinking Materials Summit in London on May 16-17. 

Solutions include next-gen materials created from bio-based feedstocks and AI powered R&D platforms accelerating new material discovery. 

Innovators will pitch their solutions and field questions from investor panels in three themed Technology Showcase sessions –

Material Innovation Delivering on Performance and Functionality introduces four start-ups focused on sustainable, high-performance materials of the future, with investors from KOK PROJECT and ASTANOR VENTURES.

Innovation Supporting the Decarbonisation and Circularity of Materials hands the mic to innovators with technologies promoting the decarbonisation of materials in a value chain, with investors from Cell VC and Planet A.

Solutions Supporting Efficiencies in Materials presents four innovators leveraging digital technologies to enhance and prolong the lifecycle of materials, with investors from Blue Horizon and Mass Challenge.

  • Materiom uses open data and AI to empower scientists, material developers, and brands to accelerate R&D and drive massive market entry of new biomaterials.
  • MicroByre works to accelerate the transition to a circular bioeconomy through the domestication of reluctant and rebellious bacteria.
  • Polygreen is a sustainable alternative to commonly used super absorbent materials in packaging and hygiene products.
  • Reselo develops novel biomaterials from abundant biomass feedstocks as alternatives to fossil-derived rubbers and plastics.
  • Ourobio harnesses microbes to turn industrial by-products into targeted, low-footprint additives for the chemicals/materials and CPG industries – lowering the cost and footprint of producing high-performance bio-based products and packaging.
  • Tandem Repeat develops tunable, adaptable, and programmable protein-based bioderived materials.
  • Xinterra combines Artificial Intelligence and High Throughput Experimentation tools to accelerate the development of materials, starting by textiles that can remove CO2 directly from air.
  • Solutum is a developer of biodegradable products designed to offer an alternative to plastics and polythene packets.They’ve created a compound that can be engineered to create a range of flexible packaging with the most versatile end-of-life on the market.
  • Reath provides software to help businesses launch and scale reusable packaging systems that engage customers.

Commenting on the innovator showcase opportunity, Markus Solbieda, Managing Director at BASF Venture Capital, said: “New materials and innovative, as well as significantly improved, chemical processes will play a major role in reducing CO₂emissions and in dealing with climate change. In order to accelerate the required research and developments, contributions from software development, AI and quantum computing research will be crucial. To achieve significant outcomes, a lot will depend on the interdisciplinary and successful liaison between traditional chemistry and new digital tools.”

Hundreds of materials and packaging pioneers will meet at Rethinking Materials in London on May 16-17, with speakers including ABINBEV, BEIERSDORF, HUHTAMAKI, PANGAIA, and UNILEVER.

The summit brings together the full value chain for two days of high-impact networking and knowledge exchange to accelerate circular solutions in plastics & packaging and turn the tide on plastic pollution.

“Connecting innovators with investors and corporate partners is one of the greatest opportunities we have at Rethinking Materials. The full value chain must work together to stimulate innovation, to realise proof of concept, and to accelerate the market entry of new viable solutions. Only then will new circular materials make the impact we desperately need.” says Ellen McLeay, the summit’s Senior Conference Producer and Technology Scout at Rethink Events.

Rethinking Materials Innovation and Investment Summit

Scaling Materials Innovation for Decarbonisation and a Circular Economy

Rethinking Materials is an international innovation and investment summit that showcases and connects pioneering companies reimagining how materials in consumer products and packaging are produced, consumed, repurposed, and financed.

With a focus on materials innovation mitigating carbon emissions from textiles, packaging or durable goods industries, we’ll explore the technologies and material alternatives reducing our reliance on ‘incumbents’ such as petrochemical, virgin forest, and animal-based materials. The summit will examine barriers to the adoption and scale up of new materials, highlighting opportunities for greater collaboration and advancement across value chains

Now in its third year, the summit presents perspectives from brands and corporate leaders facing big questions on sustainability, business continuity, and regulatory requirements; converters and manufacturers sourcing viable, scalable, and sustainable new solutions; start-ups and producers developing innovative technologies and exploring new markets; and investors scouting the next ground-breaking innovations.

Bringing together an audience of C-Suite and Director-level decision makers including CEOs/CTOs/CSOs and VPs of Innovation/R&D/Investment, with an emphasis on thought leadership, targeted 1-1 networking and start-up pitching, this is a rare opportunity to dig deeper into debates surrounding:

Net Zero Strategies: How can materials innovation aid the race to decarbonisation?           

Supply Chain Transformation: Rethinking the building blocks for sustainable materials

Regulation & Legislation: How to comply with fast-changing legislation

Achieving Circularity: Recycling, reuse, replacement – what will make the greatest impact?

Enhanced Performance: Developments in barrier properties, durability, and functionality

Industry Symbiosis: Capitalising on cross sector collaboration and waste stream valorisation

Accelerated R&D: Leveraging big-data and AI for new materials discovery

Designing for Sustainability: End-to-end product innovation to achieve ESG objectives 

Feedstock Sustainability & Security: The impact of global events on material innovation

Financing Growth: Investment and partnership strategies to accelerate scale-up

Routes to Faster Commercialisation: Bridging the gap from lab to market

Agile Innovation: Discovering new applications and markets for today’s solutions

Join us live in London on May 16-17, 2023, at this pivotal time for innovators and investors in the sustainable materials ecosystem.
