For the disposal of wood waste under ecological conditions, information about its hazardous potential and the logistic aspects for its handling is needed. The main criterion to evaluate the hazardous potential besides the determination of the type and quantity of active ingredients in the wood will be the degree of mixture with different treated or untreated timber. Assortments can be homogeneous (e.g. creosoted ties), partial homogeneous (e.g. poles with various chromium containing types) and mixed (e.g. wood from demolition of buildings). To improve the possibilites of re-using, recycling or disposal, a comprehensive survey on the structure of ownership, the kind of accumulation and the quantities of waste wood will provide with basical information. The evaluation of these logistical aspects can help for example to avoid mixed assortments, to decide whether separation as well as concentration may be useful and possible and to choose a suitable disposal method. As conclusions unsolved problems are identified.
