£700k · Pre-Seed · Cleantech · London, UK
Metal Morph, a London-based water-technology startup that recovers treatment chemicals from wastewater, has raised £700k in pre-seed funding. Sustainable Ventures and Green Angel Ventures co-led the round, with Aqcelerator and Found Capital participating. The capital will support further technology development, industry pilots and validation with water utilities and industrial partners.
Turning a disposal stream into repeat supply
Water plants use aluminium- and iron-based coagulants to bind contaminants so they can be removed. Those chemicals normally leave the process in residual sludge. Metal Morph says its patent-pending process extracts the metals, separates them through an ion-exchange membrane, recovers process acid and purifies the resulting coagulant for reuse. The system is designed as a modular, containerised retrofit rather than a replacement for the treatment plant.
The company reports more than 50 bench-scale live tests across three drinking-water treatment plants, with up to 90% recovery at 95% purity. It also reports a 26% reduction in coagulation-related operating costs and up to an 89% reduction in emissions associated with procuring fresh coagulants. These are company-reported results; the next step is showing that the same performance holds during longer industrial pilots across different wastewater streams.
The commercial mechanism is as important as the chemistry. Metal Morph plans to offer the equipment through infrastructure-as-a-service contracts with no upfront capital expenditure for customers. If the recovered chemical consistently meets plant specifications, a utility can replace part of a recurring procurement bill while reducing disposal volumes. That service model may lower the initial adoption barrier, but it makes uptime, recovery yield and verifiable savings central to the economics of each deployment.
Moving from bench tests to utility validation
Green Angel Ventures says Metal Morph has partnerships with six UK water utilities, including Anglian Water and United Utilities, which together cover 56% of the UK market. Partnerships are not the same as commercial rollouts, but they give the startup access to operating environments in which it can test feedstock variability, plant integration and customer payback.
The equity sits alongside a £100k Ofwat innovation grant, with a further £450k available if milestones are met. That blend of venture and non-dilutive funding is well suited to a company whose immediate task is technical validation rather than rapid software-style distribution. For investors, the decisive milestone is not another laboratory result but repeatable performance in the field: proving that circular chemistry can become dependable water infrastructure.
