Carbofex offers a premium grade of biochar for the horticulture industry and water filtering applications. Our biochar captures and stores more CO2 than is emitted in the manufacturing. One tonne of Carbofex biochar removes 3,2 tonnes of CO2 eq. from the atmosphere into long-term storage in the product.
Carbofex is the first Puro.earth-certified biochar producer in the world and created the PYCCS methodology together with Puro.earth.
How it works
Biochar is produced from biomass or biowaste, through pyrolysis (heating in high temperatures in the absence of oxygen). Pyrolysis creates a very stable, solid form of carbon that can endure in soil for thousands of years, making it an ideal technology for scalable carbon removal. Carbofex biochar is manufactured from spruce thinnings of sustainably managed Finnish PEFC-certified forests. The raw material would thus decay, as CO2 to the atmosphere, without the project.
After the state-of-the-art process a kilo (kg) of the resulting biochar embodies 3,4 kg of CO2 and has caused 0,240 kg of fossil CO2 emissions from cradle-to-grave i.e. from harvesting the wood to the end-customer use phase.
The resulting biochar has high fixed carbon content (94,8%) and chemical and structural stability far greater than in the original materials and removes 3,2 tonnes of CO2 eq. from the atmosphere. It has multiple commercial uses at potentially industrial volumes, for example, as greenhouse additive, in soil regeneration and in wastewater treatment.
The biochar production is verified for carbon negativity by DNV GL, and issued CORCs per each tonne of CO2 removed from the atmosphere. Life-Cycle Assessment made by Ecobio followed the methodology described in ISO 14040 and ISO 14044 standards where applicable.
Puro.earth CORCs only quantify the net-removal and storage of emissions, not reduced or avoided emissions, increased biodiversity or other positive benefits. Here are co-benefits self-reported by the removal supplier.
Excess energy at the pyrolysis plant is used to offset (replace) peat and natural gas inputs - at the Nokia district heating network.
The revenue acquired by carbon removal suppliers propels their growth, compounding the climate effect and accelerating the carbon net-negative economy.
1 tonne of Carbofex biochar removes 3,2 tonnes of CO2 eq. from the atmosphere into long-term storage in the product. Life-Cycle Assessment made by Ecobio followed the methodology described in ISO 14044 and ISO 14064 standards where applicable.
Carbofex's biochar carbon removal project was reviewed by Carbon Plan, a non-profit research organization that analyzes carbon removal opportunities based on the best available science and data. Their report and comments are publicly available for carbon removal mechanism, volume, negativity, permanence, cost, additionality and specificity, here https://carbonplan.org/reports (search for Carbofex)
