1. INTRODUCTION COST ACTION E22: Environmental optimisation of wood protection In this age when product quality is the means of survival in the highly competitive business world, it is essential for wood as a raw material to preserve superior features in terms of processing and stability. Due to its outstanding characteristics, wood is used in various fields as civil and industrial engineering, furniture, sports equipment, etc. In most of those cases, wood is subject to extreme working conditions as directly exposed to weather, soil, sea water and subsequently attacked by destructive microbial agents that could damage wood structure unless it features a high natural durability. Since the availability of high natural stability wood is currently decreasing, for a better utilization of wood resources with lower durability, their resistance to microbial attacks is strengthened by protective treatments. While the current wood exploitation in Romania it is about 12,600,000 m 3 /year (out of which 5,000,000 m 3 of coniferous and 7,500,000 m 3 of hardwoods) an increasing demand has been encountered for new wood preservatives. Keeping account of the stated objectives of the COST E22 as well as having in mind the particular national conditions, the wood protection activities are oriented towards the resolution of the following issues: • the development of new products and technologies for their practical application with the agreement of the Health Ministry on the permitted toxic features (DL50>1000 mg/kg body). • the achievement of the following characteristics for the protection products: - superior efficiency while using wood in risk classes 4 and 5; - high linking; - decreased adversity on the environment; - optimum service life and biodegradability. • the development of instructions and technologies (including work protection and security measures) for the utilisation of each preservative product depending on the specific sort and destination of wood. • There has been observed an increase of the demands for the utilisation of wood in the civil engineering sector, energetic, naval industry, hydroenergetics and transportation sector (prefab houses, power-live poles, pontoons, railway sleepers, props, sporting, boats, etc). • In accordance with the structure of the COST E22, Romania is to be represented in the Working Groups "Performance", "innovation". 128
