Biochar can be made traditionally on a small scale, in bespoke kilns, or even in large kilns the size of shipping containers with lot’s of high-tech functionalities. The traditional way biochar is made is in a fire, arranged in a special way, which minimises the oxygen around the wood and prevents the charcoal turning to ash. Unfortunately this method is bad for our climate as it releases a lot of smoke, and overtime it’s also bad for the people because they end up inhaling lots of smoke in the process. 🔥⠀⠀⠀⠀⠀⠀⠀⠀⠀
Biochar made in bespoke kilns, either small ones or large ones, is made at a higher temperature to improve the structural qualities of the biochar, which in turn improves the properties in the soil. A higher temperature results in a crystalline structure of carbon, so in the soil the water and fertiliser retention is maximised, and the carbon is locked up in tight molecular bonds. 💪🏼⠀⠀⠀⠀⠀⠀⠀⠀⠀
This last point means microbes cannot breakdown the carbon, so rather than being biodegradable (and releasing the carbon back into the atmosphere), the carbon instead stays in the soil and is a form of carbon sequestration and storage (hence it being carbon negative!). 🌍⠀⠀⠀⠀⠀⠀⠀⠀⠀
We’ve designed a small-scale bespoke kiln which you can use in your garden to make biochar. It’s the safest and most effective way to make it at home. Let us know what you think of it’s design! We decided to incorporate the structure of biochar in the chimney decoration.
