I do some woodworking and plan to compost my sawdust from lumber.
I'm concerned about plywood dust due to the glue used. Any thoughts?
The CCA (chromated copper arsenate) has been replaced with copper quaternary amine (IIRC). Basically a type of surfactant that is also toxic to fungi. Think copper soap. I haven't done formal research on it but my first impression is to leave it out, not so much because of human toxicity (we can tolerate a lot of copper in comparison to Cr or As), but because it has the potential to be toxic to the compost pile itself.wsommariva wrote:Thanks for the reply. How about pressure treated wood? I don't use much and I hear that arsnic is no longer used in it.
