The principles of residues disposal are outlined in Article 5 of the Bill on waste from the 27th of April 2001 [Ustawa 2001] which states that activities connected with waste creation should be carried out in such fashion that both the waste quantity as well as its negative impact on the environment should be minimized during production, when using the product and in subsequent period of its utilization. In case residues cannot be eliminated the bill prescribes to either utilize or recycle the residue in question. Article 9 of the bill additionally states that the residue should be utilized or recycled in the place of its origin, when it is not possible the residues should be transported to the nearest place where such utilization or recycling process could be carried out. Despite recently observed technological development, especially in larger sawmills, resulting in the decrease in the amount of waste, wood breakdown still remains a significant source of residue creation. Sawdust and shavings utilization does not represent any problem. The wood waste which has not been used in the place of its origin for fuel becomes valuable raw material for numerous clients fiercely competing for it. Apart from pulp and paper industry, particle and chipboard producers, garden furniture producers as well as briquettes and pallets producers various other very strong competitors have emerged: power stations being one of them. Those plants, in a very controversial way though, have been implementing recommendations from the most important for the sector document on: Renewable Energy Development Strategy [Strategia 2001] which obliges power plants to increase the share of renewable sources in country fuel-energy balance from 7.5% in 2010 to 14% in 2020. Energy sector does not undertake very expensive investments linked to the construction of solar and wind power stations. In order to fulfil European Union requirements it uses much cheaper and easily obtainable source of renewable energy that is wood waste. Due to high penalties for not fulfilling the Treaty's provisions energy sector is willing to pay a lot for the residues becoming a significant thread for other recipients of that material(fragment of text)
