10181451MelioShield as a Bio-Based Alternative to PFAS in Hydrophobic Coating ApplicationsClosedCollaborative R&DInnovate UKPer- and polyfluoroalkyl substances (PFAS) are a group of extremely persistent and increasingly restricted chemicals, creating compliance risk and forcing reformulation. Manufacturers now need fluorine-free alternatives that hit performance targets without changing existing lines -- ideally made from circular, locally sourced feedstocks. Demeter Bio will run a short feasibility project to validate MelioShield, a PFAS-free, bio-based material designed to replace persistent chemicals in coatings application. MelioShield is produced from waste streams, turning a low-value waste into a high-value functional ingredient. The project focuses on three practical steps that help transition from lab to real-world use. The project plan includes material production and optimisation with 20L scale-up simulations, efficacy validation through hydrophobicity testing both in-house and with accredited labs and material data collection. The project will deliver a concise Feasibility Report summarising methods, results and next steps, along with a materials data sheet and pilot-ready recipes. Together, these outputs will provide clear evidence for customers and investors that MelioShield can offer PFAS-like functionality without fluorine, using a circular, locally sourced feedstock. This work supports the UK's drive for resource efficiency and supply-chain resilience by replacing persistent chemicals with a biodegradable, bio-based alternative and by building the evidence needed for rapid, low-risk adoption. All activities will be conducted in the UK.
