Thermal Valorization of Wood Waste by Pyrolysis at Low Temperature

Recycling of waste wood is important for the effective utilization of natural resources. Thermal degradation process seems to be a promising technology for material and energy recuperation out of CCA treated wood waste. The charcoal product resulting from CCA treated wood contain Cu, Cr and As. The research aims at thermal valorisation of CCA treated wood waste using low temperature pyrolysis at different heating rates. During pyrolysis an agglomeration process takes place which results not only the growth of existing mineral agglomerates but also the formation of new agglomerates. The chemical and the physical characterizations of pyrolysis solid products show that the CCA treated wood waste could be used for the production of materials in particular charcoal with high specific area and CCA metal agglomerates.
