Biochar versus aliens…

A sustainable energy manager I know just came across another report on some of the findings from Stonelaws Farm in Scotland where the benefits of biochar are currently being assessed. For those of you who haven’t heard of it, biochar is plant waste which is heated at very high temperature in an oxygen free environment so that it does not burn. The result is gases/ liquids which can potentially be used as fuel or agricultural treatments and a dry, carbon rich solid similar to charcoal which when added to fields can enhance crop yields whilst retaining the carbon it contains for years…

As the article mentions seemingly “Win-Win-Win-Win”. Sceptics do remain (and in any case it is probably good to make sure we really understand the full impact of biochar before we heat all our plant waste), but generally
