Concretene, the Manchester‑based DeepTech company developing graphene‑enhanced, low‑carbon concrete, has been named a winner in Ofwat’s sixth Water Breakthrough Challenge. The winning project, “Splitting Biogas, Multiplying Value,” is led by UK water utility United Utilities and aims to show how wastewater biogas can be converted into clean hydrogen and high‑value graphene, then used across construction, energy storage and transport applications.
