We help water companies decarbonise and get value out of their wastewater
METzero eliminates the need for energy-intensive aeration, which accounts for 50%—60% of all energy demand within traditional wastewater treatment processes. It operates at ambient temperatures, so there is no need to spend energy heating up the reactor. Microbial electrolysis significantly lowers indirect greenhouse gas (GHG) emissions by reducing energy consumption. Facilities using METzero can save over £0.5 million annually on energy bills and cut GHG emissions by up to 30%.
METzero harnesses the power to extract economically valuable products like hydrogen and ammonia from waste streams tailored to the specific needs of our clients. Our pilot reactors have proven successful in recovering these resources, which can be used to upgrade biogas injections into the grid or to help decarbonise plant operations and fleet vehicles. Deploying METzero at a single large treatment facility could generate enough hydrogen to power a substantial fleet.
METzero’s adaptable design allows for retrofitting within existing treatment plant infrastructure or modular, containerised deployments to gradually enhance capacity. By treating high-load sludge liquors, which contain significant levels of ammonia and phosphorus, our solution can relieve 10-20% of the systemic load. This flexibility ensures that METzero can integrate seamlessly, whether the return line is treated as part of the main system or separately.
2012
World's first proof of concept Microbial Electrolysis (MEC) Pilot which gave us the cassette design and proved that the technology can work in the field.
2013
Continuous operation for 12 months treating raw domestic wastewater and recovering energy at ambient temperatures even as low as 1 °C showing resilience and adaptability.
2020
Optimised reactor treating real wastewater with higher soluble organics (sludge liquors) and achieving the highest volumetric treatment rate recorded for a pilot-scale MEC.
