Abstract: According to Québec’s Règlement sur les matières dangereuses, wood residues containing resin are likely to be toxic residual dangerous matters because of their formaldehyde content. The management of these residues is problematic for the secondary board manufacturers because the majority might not operate a combustion boiler with high enough power to burn board residues in conformity with regulatory requirements. The recovery of these residues could be possible, but no decision can be taken without knowing the nature of the residues. The objective of this study is to characterize the residues coming from the secondary board manufacturers in the province of Québec in order to find opportunities for recuperating, recycling or disposing of these residues. A survey of secondary board processing plants has been conducted to draw a picture of the disposal of residues. A mail questionnaire was sent to a sample of plants within each industrial sector. The five points of contact method was applied, yielding a response rate of 32%. A quantification of the residues was made and the data was used to extrapolate the results to the whole of Québec industry. A segmentation of the results according to the size of the plant or to the industrial sector was made and significant differences were found between classes regarding the management, the use and the contamination of the residues. The majority of secondary board manufacturers send their board residues to landfill sites. This is the case of most small size mills. The survey indicates that 30 percent of the mills have experienced serious problem in managing these residues and they have already tried to find a better solution to dispose of them.
