Status of the research and development of a new preservative system (EFPL) for pressure treatment of spruce in Canada
1975 - IRG/WP 348
Our work has been to develop a system which would have the stability of the ACA system and the formulation flexibility of the CCA system enabling properties such as fixation of arsenic, water repellency, appearance and cost to be controlled. Our permeability studies of spruce using a method previously developed indicated that an ammoniacal solution of copper arsenate is an excellent candidate for ...

The status of marine wood preservation in Papua New Guinea
1974 - IRG/WP 405
The life-expectancy of Papua New Guinea hardwoods in the marine environment has in the past been too short to be an economical proposition, a service life of six to twelve months being obtained from some of the timbers susceptible to marine wood borer attack. Consequently plans for wharves and other marine structures have specified the use of imported materials such,as steel and concrete. Due to t...

Status of wood preservation in India
2005 - IRG/WP 05-30386
Wood, despite the advent of other modern materials, continues to play an important role in man’s day to day life. Usage of wood ranges from fuelwood to engineered wood products and demand for it is increasing which has resulted in depletion of forests and diminishing wood supplies. Future needs are required to be met from plantation timbers after adopting processing technologies for their life...

Industrial wood preservation in Kenya. Present status – future prospects
2005 - IRG/WP 05-30385
Although some 50 years old, industrial wood preservation in Kenya does not appear to have technically, scientifically, and commercially evolved and contributed to significantly extend service lives of timbers, protect health and the environment, and curb unnecessary over-exploitation of forests. The population of the country has increased by 530% over the past 50 years; regular excisions have red...
