pyrolysis gas and biochar are produced from organic residues.

The resulting biochar can be sold directly or further refined with technologies from our partners and then sold. The market for biochar has high double-digit growth rates and is becoming increasingly important, mainly because of its outstanding properties for soil improvement, nutrient and water retention. With biochar, soils become more fertile and resilient to the effects of climate change. The operation of an autarkize plant earns between €130,000 and €500,000 annually from the trade in biochar.

Biochar consists of carbon that has been removed from the air as CO₂ by the plant during its growth. Incorporated into the soil, it represents a permanent CO₂ sink. One ton of biochar corresponds to between 2 and 3 tons of CO₂ equivalent that has been permanently removed from the atmosphere. Negative CO₂ certificates (e.g. carbon dioxide removal certificates) can be issued and marketed via this CO₂sink. The market for CO₂ sinks from biochar experiences a very high demand and even with a conservative estimate we expect market prices of 100-150 € per ton in the next years. This results in an additional revenue stream of €30,000 to €800,000 per year. Depending on the size of the plant, 150 to 1800 tons of biochar will be produced, thus removing 300 to 5,500 tons of CO₂ from the atmosphere.

autarkize plants can utilize a wide range of biomasses. Among them are also biomasses which today are disposed of cost-intensively e.g. on municipal level (green waste, waste wood, sewage sludge) or are resold e.g. in agriculture and food industry with very low proceeds (husks, peels, pomace, digestate, ...). Operators of autarkize plants can enter these markets and collect or save the disposal fees. Depending on the biomass, this results in a further revenue stream of between €50,000 and €250,000 per year.
