Voices of Regeneration: Founders Driving Innovation

This special episode of The Stream takes you inside Northumbrian Water’s Innovation Festival 2025, where this year’s theme, Regeneration, inspired bold ideas and brilliant collaborations.

Tom sits down with five founders and innovators in water, sustainability, and infrastructure. From 3D-printed concrete and microbial electrolysis cells to citizen-powered AI and leakage detection, these conversations shine a light on the future of the industry, and the minds building it.

Featured guests:

• John Marsden, Origin Tech – Detecting and fixing leakage through satellites
• Natalie Wadley, Changemaker3D – Reinventing concrete and enabling 3D printed infrastructure regeneration.
• Kapil Singhal, Vyntelligence – Using AI and citizen science to streamline water operations.
• Pavlina Theodosiou, MetZero – Advancing circular wastewater treatment through microbial electrolysis.
