INFLUENCE OF CONTAINED ADHESIVES ON THE PYROLYSIS CHARACTERISTICS OF WOOD BIOMASS
In recent years the use of plywood and laminate lumber as construction material has been increasing rapidly. The wood waste, containing synthetic polymer, such as adhesives, is expected to become a large quantity of material during the next 15～20 years. Although the demand for quality waste wood is increasing, waste wood material mixed with plastics or containing adhesives has low recycling value, and in most cases it is discarded. Therefore, it is necessary to develop techniques for processing it effectively. One technique for creating gaseous and liquid fuel out of wood is pyrolysis. The study investigated the outcome of pyrolysis in which synthetic polymers (plastics and adhesives) and wood biomass from construction materials were mixed at temperatures ranging from 300℃ to 500℃ at standard pressure and in a nitrogen atmosphere. Taking a compreg as samples, the pyrolysis characteristics of wood biomass mixed with synthetic polymer were studied using a thermogravimetric analyser (TGA). In the TGA measurement, wood containing adhesives was found to have a lower peak temperature of heat weight loss compared with wood not containing adhesives. It was demonstrated this experimental result is caused when the decomposition reaction of cellulose was influenced by adhesives.
