The objective of the research was to improve the combustion properties of byproducts from mechanical wood processing by developing the fuel storage and handling. The research was divided into three subtasks: 1) the optimisation of the storage of bark, 2) reduction of the moisture content of the bark, and 3) removal of impurities from the fuel. The main focus in the research was the storage experiments, where spruce and pine bark was stored 1-12 months. During first three months the bark dried 3- 8%-units. When the storage time was continued the storage started to get wet and after 12 months it reached almost the same moisture content as before the ex- periment. The changes in other properties, excluding ash content, were small during storage. The best results with regard to energy content were achieved in 1-2 months of storage.
