MATTER

MATTER is a cleantech company based in Bristol, UK, developing self-cleaning filtration technology aimed at capturing microplastics before they reach rivers, oceans and water supplies. Its principal product, Regen.®, is a self-cleaning filtration system designed to capture microfibres shed during washing cycles, with a stated capture rate of up to 97%. The technology is intended for integration into both home appliances and industrial systems, spanning applications in laundry, textile manufacturing and water utilities.

The company's commercial model rests on partnership rather than direct appliance manufacture. MATTER works with major appliance manufacturers - including BSH (Bosch) - and textile manufacturers to scale Regen.® into existing production lines. Its stated focus is on commercially viable solutions capable of transforming the industries it addresses, alongside commitments to sustainable design and the circular economy. The team is composed of engineers, scientists and innovators working across filtration technology, microplastic capture, materials and environmental engineering.

MATTER holds B Corporation certification and was named an Earthshot Prize 2025 Finalist. The market context is defined by scale: millions of tons of microplastics enter waterways annually, and washing cycles are a documented source of microfibre shedding, positioning filtration at the appliance stage as a point of intervention upstream of water treatment.
