What's the climate impact?

This biochar is carbon net-negative – 1 ton of Carbofex biochar removes 3,11 tons of CO2 eq. from the atmosphere into long-term storage in the product. Life-Cycle Assesment made by Ecobio followed the methodology described in ISO 14040 and ISO 14044 standards where applicable.

 

 

Economic stimulation effect

The extra income from Puro allows Carbofex to grow existing biochar production and therefore, remove more carbon from the atmosphere. Extra income also stimulates the development of new products such as phosphorous removal system for lakes and water ecosystems.

 

How it works

Biochar is produced from biomass or biowaste, through pyrolysis (heated in absence of oxygen). Pyrolysis creates an aromatic stable form of carbon, which will stay away from circulation.

Resulting biochar has high fixed carbon content and chemical and structural stability far greater than in the original materials.

The production is verified for carbon negativity by DNV GL, and issued CORCs.
