At present, the main conventional source of energy used all over the world is the fossil fuels which are non-renewable and
hence their deposits will eventually be exhausted. Wood is one of the oldest fuel sources known to man. Research have
shown that about 80 million cubic metres, equivalent to 43.4 x 109 kg (or 43.4 million tonnes) of fuel wood with an
average daily consumption ranging from 0.5- 1.0 kg of dry fuel wood per person is being consumed in the country
annually for cooking and other domestic heating purposes. This study discusses the quantity of wood waste generated in
saw mills in Nigeria. The environmental implications of improper disposal of sawdust arising from sawmills are also
analyzed. Essentially, the economic potential of sawdust is discussed. It was revealed that saw dust waste left at the saw
mills causes aesthetic problems while abandonment along the road side causes air pollution as a result of wind which often
blows and suspends the wood dusts into the atmosphere.
