Biochar

Biochar is charcoal that is produced by pyrolysis of biomass in the absence of oxygen.

Biochar is one of the most efficient ways of storing CO2 (carbon) long-term. As long as biochar is not incinerated it serves as a stable carbon sink for thousands of years, ensuring that CO2 will not be released again.

Biochar use in agriculture includes animal feeding, manure treatment (e.g. as additive for bedding, composting, storage or anaerobic digestion), fertilizer component or direct soil application. Because the feedstock carbon is photosyn-thetically fixed CO2 from the atmosphere, pro-ducing and applying biochar is essentially a CO2 removal (CDR) technology. Biochar use in agriculture delivers co-benefits by improving crop yields and ecosystem services and improves climate change resilience by ameliorating key soil properties.

We produce biochar from FSC-certified bamboo in cooperation with local farmers and cooperatives, as well as in our own facilities.

Our biochar is used for the production of Terra Preta, as an additive to livestock fodder, in wastewater and drinking water treatment and in many more applications.

Biochar, with its excellent capacity to remove many contaminants from aqueous solutions, constitutes a perfect technology for drinking water and wastewater treatment. Biochar water treatment has several potential merits compared to existing low-cost methods (i.e., sand filtration, boiling, solar disinfection, chlorination).

Biochar can be used in multi-layer and trickling filters as well as in constructed wetlands.
