an active international discussion regarding substitute materials
for treated timber and alternative preservatives for timber, particularly
in those jurisdictions where the use of CCA-treated timber has been
significantly limited, such as the EU and US. International symposiums
are regularly planned for industry, government and academic researchers.
Indeed, in March 2005, the American Chemical Society is hosting
the Health, Environment And Efficacy Issues In The Development Of
Commercial Wood Protection Systems, and the International Research
Group on Wood Preservation is planning their 6th symposium for February
2005, which will consider issues new wood preservatives and treatments
and risk and waste management in wood preservation.
