"I cannot conceive of a situation where more toxic treatments such as CCA, ACQ etc. would be considered green, or even allowable in green building." - Doc
I read your above comment from the Dovetail website in a question & answer segment - this particular comment came from an inquiry on BluWood
I have attended a few of your seminars and wondering what your latest thinking is on chemically preserved wood?
I am also researching the 'green' value of composite / vinyl / plastic decking. I did not find any LCA research on the BEES website. Any help?

Intelligent people have been claiming the benign environmental nature of chemically preserved wood for over 50 years – including products using creosote, penta, and CCA – and each of these products lead to superfund clean-up sites. So the industry’s record is not good in terms of understanding the nature or risk of these kinds of products. I still remember a conversation I had back in the late 1980’s with a professor at a well know university, as he confidently espoused the benefits of the product since the materials were permanently chemically bonded to the wood. I asked “IF the chemicals are permanently bonded, why is there only a 50 year guarantee, and why does wood appear to eventually rot?" He didn’t have an answer. ACQ has not been without its problems either. As CEO of a company that has sold a lot of ACQ, I know the devil’s in the details and there is a LOT of ACQ product in place without appropriately protected fastening systems. Any product that needs “special” fasteners - different than are historically the case - is a challenge. It doesn’t mean it can’t work – it just means it is potentially problematic. I do not have enough detail about the new osmose product to have an opinion at the moment but, the test is: are you required to where gloves and a mask when working with the product? In general, and in my experience, IF it is toxic to work with it becomes toxic to the environment.</span></span></span></p>
