New biochar centre launched

Charcoal produced at the University could be the latest tool to help tackle climate change. A new unit at the University will produce biochar - a charcoal-like substance produced through the oxygen-free, slow heating of agricultural waste. Researchers say that when biochar is added to soil, it increases its carbon content - building a long-term store that counters excess carbon dioxide in the air and helps to reduce other greenhouse gas emissions. The process of producing biochar also releases energy-rich gases and liquids that can be used to generate green energy, thus offsetting the use of fossil fuels. The biochar material itself can help soil retain nutrients and water - potentially resulting in higher crop yields for farmers. Biochar can help to improve soil quality and allow better waste management and soil improvement - all on a scale achievable by a town, village or farm, researchers say. Biochar is a process that can take carbon emissions out of the atmosphere.
