The images are examples of biochar, that have been produced from rubber trees in a small-scale gasifier, used for generating electricity in remote rural areas of north-west Cambodia. Biochar is rich in carbon molecules that are resistant to mineralisation by microorganisms and is therefore a potentially important way of storing carbon long term in soils, helping to limit atmospheric CO2 concentrations. The UK Biochar Research Centre is an interdisciplinary centre established to develop scientific and engineering understanding of biochar and of its potential role in tackling climate change.
