This paper presents some technical aspects and management issues of wood waste reuse and disposal. It refers to the Greek and European legislation which determines the framework for rational and Environmental friendly practices for wood waste management. It refers also to the wood waste classification systems and the currently applied methods of wood waste disposal and reuse. Emphasis is given to the wood waste-to-energy conversion systems, particularly to the pre-treatment requirements, the combustion techniques and the environmental constrains. Finally, the decision-making process for investments in wood waste firing thermal units is discussed.
