Biochar

Biochar is the leading durable carbon dioxide removal technology in both delivery and market liquidity. The Puro Standard brings integrity to the market with high-quality carbon removal methodologies, including the world’s first and leading biochar methodology.

biochar

Biochar is produced by heating biomass at high temperatures in the absence of oxygen. This process, called pyrolysis, converts biomass into a stable form of carbon that can store carbon dioxide removed from the atmosphere for at least 200 years, while also delivering social and environmental benefits.

key benefits

Industrial scale and agricultural productivity

Various industrial end uses

End uses with the potential to scale to industrial volumes, including as a greenhouse additive, in soil regeneration, and in stormwater or wastewater treatment.

Improving productivity

Biochar is proven to help increase crop yields, while also creating value from recycled bio-waste.

Positive impact beyond carbon

Projects can support local communities through job creation, stronger local value chains, and more productive use of waste biomass.

200+ year storage

Durable sequestration and soil productivity

Biochar enables carbon sequestration for 200+ years with a low risk of reversal. Beyond carbon sequestration, biochar can deliver wider environmental, social and economic benefits. It can support agricultural productivity by improving water and nutrient retention in soils, be used in wastewater treatment and site remediation, and generate renewable energy through the pyrolysis process.
