Carbon Footprint

The biochar production process plays a key role in reducing the carbon footprint. Traditional methods (in the presence of an oxidizer and without controlling the pyrolysis process and combustion of pyrolysis gases) require up to 12 tons of dry raw material to produce one ton of biochar. At the same time, about 25% of the resulting product consists of fractions of less than 1 mm, which reduces the amount of conditioned product and increases the carbon footprint.

Modern technologies, including complete combustion of pyrolysis gases and control of the pyrolysis process without oxygen access through automated control systems (ACS), allow reducing the consumption of raw materials to 6 tons per ton of biochar, approaching the theoretical maximum product yield. At the same time, the proportion of fractions less than 1 mm is reduced to 1%. These technological improvements not only reduce raw material costs but also CO₂ emissions during biochar production.

Technological Solutions for Reducing the Carbon Footprint

1. Complete Combustion of Pyrolysis Gases: 100% combustion of pyrolysis gases prevents the release of methane and other harmful substances into the atmosphere. This allows for the efficient use of all the energy released in the process, significantly reducing the carbon footprint.

2. Pyrolysis Process Control: Pre-drying of the raw material prevents moisture from coming into contact with active carbon and part of it from transitioning into the gas phase. Controlling the pyrolysis process (without oxygen access) prevents excessive raw material consumption, improving the yield of the finished product. It allows obtaining biochar with a high content of non-volatile carbon and minimizes emissions of harmful substances, including CO₂. Controlling the rate of the exothermic reaction also allows increasing the carbon yield in the solid phase and avoiding its transition into the gaseous phase, which contributes to a higher product yield, as well as increasing the mechanical strength of biochar, which ensures its preservation during transportation and expands the scope of its application. Due to the low mechanical strength of biochar, transportation leads to an additional fraction <1mm of up to 5% for every 100 km traveled.

3. Automated Control Systems (ACS): Using ACS to control all stages of biochar production ensures optimal process parameters, reducing raw material and energy consumption and significantly reducing CO₂ emissions.

4. Cloud Solutions: Cloud technologies enable real-time monitoring of the production process and emissions, making data available for monitoring and analysis. This improves process transparency and opens up additional opportunities for environmental reporting.

Economic and Environmental Benefits

Modern biochar production technologies not only help reduce the carbon footprint but also significantly reduce raw material costs—6 tons instead of 12. A higher product yield and improved quality increase the market value of biochar, opening up new opportunities for its use in industries such as agriculture, metallurgy, construction, and the chemical industry. These approaches can also contribute to obtaining carbon credits, providing an additional source of benefits for businesses focused on sustainable development.
