And now for something quite different: how can chickens provide not only that delicious breakfast egg, but also the power to cook it? The answer lies in that plentiful by-product of the chicken farm, namely, chicken dung. An enterprising British company has proved that ’green’ solutions to the electric power needs of communities can be profitable. In fact, there are already three, yes three dung-fired power stations in use in Britain, which have attracted attention from other European countries and several projects in different places are already at the advanced planning stage. ’We first believed that the only use for our dung was to make electricity,’ says the British company’s owner, ’but after burning it for power, we are left with a residue rich in potash and phosphate, but nitrogen-free. This provides a far more marketable fertilizer which we can sell as well as the electricity we produce.’ In many countries, agricultural waste is seen more of a problem than industrial waste, polluting even the sea where rivers have carried nitrogen and other agricultural waste to estuaries and inshore waters. By burning dung and producing cheap electric power in the process, however, this company is solving two problems in one go.
