+=====This dark material: the black alchemy that can arrest carbon emissions=====

+ It traps carbon in the ground for centuries, boosts plant growth, provides a sustainable heat source and could even reduce methane emissions from cows. Biochar may not be a silver bullet to combating the climate emergency, but it certainly ticks a lot of boxes.
+ Following biochar’s recognition in the IPCC 2018 report, earlier this year Redmile-Gordon launched the society’s first trials to see how the material could improve plant growth. He estimates planting 10-20kg of biochar in your garden could offset the carbon from a five-mile return commute in a car for a month.
+ Biochar is a form of charcoal produced when organic matter – for example wood, leaves or dead plants – is heated at high temperatures with little or no oxygen in a process called pyrolysis. The normal burning or decomposition of these materials would release large amounts of methane and carbon dioxide into the atmosphere. Instead, creating biochar traps this carbon in solid form for centuries; it becomes a carbon sink that can be buried underground.
