Inside Carbogenics’ Novel Biochar Technology

30 June 2025

In this episode of the Raw Green podcast, Ed Craig, CEO of Carbogenics, joins co-hosts Francesco De Lieto and Emma Mee to discuss how it is turning difficult-to-recycle waste into biochar for anaerobic digestion and wastewater treatment industries.

They explore the story behind CreChar, Carbogenics’ proprietary biochar product, which transforms paper waste and secondary biomass into a stable, carbon-rich material that boosts renewable energy production while permanently locking carbon into the ground.

Ed explains how their biochar creates an optimised environment for bacteria, buffering acidity and boosting biogas yields by up to 15%. With over 700 anaerobic digestion plants in the UK alone, the discussion highlights the massive opportunity to turn marginal energy facilities into highly profitable, carbon-negative assets.

Beyond the chemistry, they discuss the commercial realities of scaling climate tech and the valley of death for funding hardware innovation. If you are interested in the practical side of the circular economy, the untapped potential of biochar in the energy sector, or the journey of taking a clean tech hardware innovation from the lab to the global market, this episode offers a fascinating look under the hood of a company making a tangible impact.
