Biochar is a carbon-rich material that can be produced from heating organic biomass under low oxygen conditions. When biochar is applied to soils, carbon is sequestered for hundreds of years, enhancing land quality and increasing agricultural yields - contributing towards a circular economy and climate change mitigation.
ATV are leveraging renewable agricultural byproducts such as rice husks, from our own production processes, as feedstock to generate biochar and green methanol products with our Research and Development partners, Trimass. Our approach differs from conventional biochar processing by removing CO₂ from the production pathway without CO₂ emissions, generating further revenue from both green methanol and carbon credit sales.
Green methanol offers a sustainable pathway for decarbonising hard-to-abate sectors, showing strong market growth since 2022. Our collaborative pilot research is currently on track for completion by the end of 2025, with scalable commercial pilot production set for mid-2026.
Biochar Produced from Mozambique Feedstock
Overview of ATV-TRIMASS Biochar and Biofuel Technology
ATV have developed technology to convert microalgae from a marginal product to be part of an agricultural mix that can be used as a nutritious supplement for animal feed in Mozambique.
As microalgae can be grown on land deemed unsuitable for food production, ATV prioritises using sub-prime farming land for the growth of microalgae, significantly increasing land productivity in selected areas and overcoming main environmental objections associated with production on agricultural land. Our growing site facility south of Chokwé, Gaza Province is currently in development.
Research is ongoing into the production of high-quality Chlorella Vulgaris, with recent progress showing yield increases of 25% and improvement to production scalability.
The current harvesting method achieves approximately 30% recovery of dry mass and involves significant human intervention and technical limitation - it also puts the crop at risk of failure from overcrowding in the tank due to harvesting limitations. This method is highly labour and energy intensive, leading to inefficient use of resources in managing staff and equipment, as well as operational downtime as tanks need to be fully drained every 7-10 days.
To address these limitations, ATV, in partnership with the University of Manchester, are developing a solution based on froth flotation and have been able to achieve much higher yields - with testing reports achieving greatly enhanced harvesting efficiency. With this and the ability to harvest continuously, we can dramatically increase our harvesting yield per unit land area, minimising both land take and the chances for Chlorella Vulgaris die off due to overcrowding in the tanks.
Currently we are completing quantification and optimisation in preparation for commercial pilot production in 2026.
