Carbogenics has raised more than £1m to help build its first research, development and production facility in Scotland.
The company turns difficult-to-recycle food, farm and paper waste - which would otherwise go to landfills or be sent for incineration - into a product called CreChar. This is a carbon-rich, porous material that should help stabilise the performance of anaerobic digestion plants.
The investment has come from new lead investor Green Angel Ventures, along with existing investors Scottish Enterprise and Old College Capital.
