WASE is a British climate tech startup that develops modular systems to convert wastewater and organic waste into renewable energy.
WASE has secured £8.5m in funding, comprising £2.4m in non-dilutive capital alongside equity investment, to scale its operations and deploy its waste-to-energy technology. The round was led by Extantia Capital, with backing from Hitachi Ventures, WEPA Ventures, Engie New Ventures, Elbow Beach Capital, and Empirical Ventures. The capital will allow the company to execute multi-million pound contracts and develop its product offering.
Founded in 2017, the company produces proprietary Electro-Methanogenic Reactor systems designed to accelerate biomethane generation from anaerobic digestion plants and wastewater. Its modular units integrate into existing industrial infrastructure to help food and beverage manufacturers reduce emissions and generate clean energy.
From the founder
"We want our technology to set a new standard in the waste treatment and energy sectors,by not only optimising waste breakdown but by boosting methane production across the board"
Thomas Fudge
Founder and CEO at WASE
Investor perspective
"We strongly believe that biogas and biomethane will soon be a key source of renewables and will make up a growing percentage of the energy mix. WASE’s approach doesn’t just increase biogas and biomethane yields from the AD process, making it more profitable and productive, it is reshaping the way industrial businesses are thinking about their resources. We think their cutting-edge technology, the know-how they have built-in commercialising their wastewater solutions, their existing supplier relationships, and their capital-efficient approach positions them well ahead of competitors in this space – and we’re delighted to support them."
