Redefining Today's Wastewater to Unlock Tomorrow's Resources

Our vision reflects our commitment to transforming wastewater from a problem into a valuable opportunity. 

By unlocking the hidden potential within wastewater, we create new resources like energy, nutrients, and materials that drive a cleaner, more sustainable future.  

Our vision highlights our role as innovators and industry disruptors, shaping a future where waste becomes a resource for progress.

Why we exist

 At METzero, we believe that every drop of wastewater holds untapped potential. Our mission is to transform this potential into tangible value — for our clients, for our planet, and for future generations. 

Our Journey: From Lab to Commercialisation

METzero Technologies was born out of a passion to solve a pressing challenge: wastewater treatment systems were falling short in an era demanding sustainability, resilience, and resource recovery. Spun out from Newcastle University, we set out to bridge the gap between innovative research and practical solutions that meet the rising demands and Net-Zero targets of water companies.


Our approach optimises energy use and reduces costs while unlocking valuable resources within wastewater that traditional methods often leave behind. At METzero, we're redefining what's possible-turning treatment plants into resource recovery hubs that increase capacity, reduce costs, and drive a sustainable future.
