The disposal of impregnated scrap and waste wood can take the form of recycling, dumping or combustion. While recycling and combustion are ways to utilize the waste dumping amounts to waste removal. Usually combustion is the preferable method of wood waste managing. When impregnated wood is combusted, the preserving additives can act as combustion inhibitors or promotors thus influencing the wood's combustion characteristics. The combustion of impregnated wood can also be accompanied by the formation of hazardous pollutants. When considering flue gas pollutants, it is necessary to differentiate, however, between those originating from full combustion and those caused by inadequate combustion. Good combustion is essential, therefore, when disposing of wood impregnated with organic agents by burning. Giving an overview of the wood preservatives the various ways of wood waste combustion are differentiated in detail.
