5. The potential of biochar for decarbonisation
Decarbonisation is about reducing carbon emissions through the introduction of clean energy technologies, efficiency improvements and other strategies to mitigate climate change. Biochar, as a product and process, plays a central role in decarbonisation as it captures carbon that would otherwise be released into the atmosphere. This overlap with the circular economy is crucial as it embodies the principles of resource efficiency and waste minimisation.
In the carbon-based circular economy, the goal is not only to use resources more effectively, but also to create systems that are self-regenerating.
Biochar is a key element in that it transforms agricultural, forestry and horticultural economic waste - biomass that is abundant but underutilised - into a stable form of carbon that can be returned to the soil.
This not only sequesters carbon for hundreds to thousands of years and reduces the amount of CO2 in the atmosphere, but also improves soil fertility and structure.
