A new $2 million biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More production facility, B10 Char, is set to launch in Mpumalanga, South Africa, offering a multi-faceted approach to environmental challenges. This facility aims to produce 7,000 tons of biochar annually from 22,000 tons of organic waste, with a projected offset of 15,000 tons of CO₂ emissions in its first year.

The technology employed is a form of pyrolysisPyrolysis is a thermochemical process that converts waste biomass into bio-char, bio-oil, and pyro-gas. It offers significant advantages in waste valorization, turning low-value materials into economically valuable resources. Its versatility allows for tailored products based on operational conditions, presenting itself as a cost-effective and efficient More, where organic waste materials, such as wood chips, are heated without oxygen to over 400°C. This process transforms biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More into a stable, carbon-rich material. While biochar can be used as a fuel, its primary application and the focus of B10 Char is its role as a soil amendmentA soil amendment is any material added to the soil to enhance its physical or chemical properties, improving its suitability for plant growth. Biochar is considered a soil amendment as it can improve soil structure, water retention, nutrient availability, and microbial activity.   More. In drought-prone regions like South Africa, biochar’s ability to enhance water retention and nutrient availability in soil is particularly valuable for agriculture.

Beyond its agricultural benefits, biochar has diverse industrial applications, including in the production of steel and concrete, improving road asphalt, and rehabilitating soil at former mining sites. The B10 Char plant, located at the former Brondal railway station, will initially process sawmill wood chips and other waste streams that are currently disposed of by burning.

B10 Char plans to market its product to farmers and agribusinesses, offering both raw and “pre-charged” forms. Recognizing that adoption of new agricultural practices can be slow, the company is developing significant incentives, including opportunities for early adopters to trial the product through an entire crop cycle before committing to a purchase.

Additionally, the facility anticipates generating revenue through the sale of carbon credits, providing an avenue for companies to offset their environmental footprint. If the initial operations prove successful, B10 Char intends to expand its production capacity by installing additional pyrolysis units at the same location.
