Woodworking industry residues often do not find proper utilization, are heaped up, pollute the environment, or are used as a fuel at best. One of the ways of using this out-of-demand but yet valuable raw material is to produce furfural, acetic acid and activated carbon by implementing an energetically self-sufficient environmentally friendly unified hydrolytic and thermal process of hardwood processing. Furfural and acetic acid are obtained by catalytic prehydrolysis of hardwood residues. About two thirds of the left-over lignocellulose is used as a fuel in a boiler house. The excessive lignocellulose should be dried and, due to its good self-binding properties, granulated or palletized and studied as a potential raw material for production of high-density activated carbon sorbents.
