Wood preservation in Spain

IRG/WP 3266

A Lopez de Roma, R Cockcroft

This report includes some statistical data on the potential of Spanish forests and the country's timber consumption as well as detailing the extent of development of the wood products industries, and will help to give a better understanding of the use of this raw material in Spain. The main biological deteriorating organisms which damage wood are given and the capacity of the industrial treatments for preventing their damage is described, including an inventory of the vacuum/pressure and double/vacuum plants, together with the consumption of the different types of preservative used. Also the extent of wood treatment undertaken by the various industries has been analysed together with the conditions which characterize these. The homologation system that permits the manufacture of wood preservatives, their import, trade and marketing is also explained and, finally, a current list of existing standards and specifications that are used in Spain is appended. From studying this paper it can be concluded that wood preservation in Spain is characterized by: 1) under-utilization of the industrial treatment capacity available; 2) a low level of treatment, except for poles and sleepers, and consequently there is a scanty consumption of preservatives; 3) a lack of standardization; and 4) there is, in many instances, a lack of adequate laws and regulations. But looking forward, the future can be viewed with optimism and with good expectations in the coming years for an increasing development of the wood preservation industry which could result in a potential saving of timber of about 10% of the apparent yearly consumption.
