Edinburgh start-up Carbogenics has appointed a new chief executive as the circular economy specialist seeks to expand its presence in the farming, wastewater and food waste sectors.

Ed Craig, former executive director of the Edinburgh Centre for Carbon Innovation, joins from his post as executive dean of the Centre for Business, Innovation and Enterprise at Staffordshire University. A spin-out from the University of Edinburgh, Carbogenics produces an additive called CreChar that improves the efficiency of anaerobic digestion (AD) plants, which in turn produce biogas for heating and liquid fertiliser.

“I’m excited about the potential for this business,” Mr Craig said. “Anaerobic digestion has a big role to play if we’re serious about net zero.”
