An issue of fundamental importance is the waste management, trying to find solutions that can be sustainable. This necessity imposes, when possible, economic profitability of the process and the minimization of environmental pressures. The present work concerns an application conducted on semi-treated wood made in more layers bonded to each other with non-chlorinated organic adhesives. In this way, also the processed waste contains a quantity, even if limited, of adhesive. This situation, according to the existing rules, does not make possible the use of such waste as fuel for energy recovery through combustion. This study evaluates different types of wood waste, virgin and semi-treated, plywood products from carpenters and submit them to a specific experimental activity, defined comparatively to check if the wood for building semi-treated with the use of non-chlorinated organic adhesives, has emissions that differ appreciably from those of virgin wood if used as fuel for a heat-generation plant. Tests have shown that the quality of the emissions was influenced more by the conduction of the combustion instead of by the characteristics of the fuel, in relation to the possible presence of small quantities of glue (vinyl with hardener or polyurethane)
