Preservative Treatment Of Wood By Pressure Methods

The purpose of this publication is to discuss the application of the results of numerous experiments and observations of the pressure treatment of wood and to present general information relating to the subject. Such information is of value to engineers, treating-plant operators, inspectors, and others interested in the preparation of specifications and in the application of pressure-treating processes.

The Nordic Council of Ministers, the BAT Group under the Working Group for Sustainable Consumption and Production, has requested the consultant to prepare a report on Best Available Techniques (BAT) in wood preservation with chemicals in the Nordic countries. The Nordic wood preserving industry produces around 2.1 million m³ of impregnated wood per year, which is about one third of the total supply of pressure-treated wood in Europe. This report describes the present status of the used technologies, their emissions and impacts on the environment and technologies that can be considered BAT. The report will also be used as an input from the Nordic countries to the EU process under the Industrial Emissions Directive (IED) for preparation of the BAT Reference Document for preservation of wood and wood products with chemicals (WPC BREF) which is foreseen to start in 2014.
