Burning (modern) treated wood

Recommended Posts

We're having some building work done at the moment and there are inevitable offcuts of treated timber. From what I've read, timber hasn't been treated with arsenic based stuff (CCA) since 2006. What is it treated with now and does it make it safe to burn (in a woodburner)?

the softwood carcasing that looks slightly green is likely copper azole treated sometimes also with borax. railway sleepers have a more effective copper treatment, possibly hydrazine. How close are your neighbours downwind that might not like to breath heavy metal oxides?

I know it's carcinogenic as vapour and a sensetiser with prolonged contact so would suspect it's better not burned in the house or on a bonfire!

Thought builders used it as firelighters to burn the kingspan offcut and plastic wrapping bonfire, or is it the other way round?

I seem to remember reading on some offical website it was safe to burn as there was no toxic chemicals in it anymore. Which is why it soon rots in the ground of course.

Try the HSE website or Environment Agency.

If it is offcuts of interior wood then is it actually treated?  It may not be.

 

Pallets used to be a right mix but now you rarely find a chemical treated one, the are almost all heat treated now so fine to burn.

Just chuck it on the wood burner when its red hot and any thing that is was treated with will soon evaporate

I fail to see why burning treated timber is an issue when you can legally burn tyres in your back garden!

Is it?

 

In any case the OP may be concerned about doing the right thing, not just whether it is legal or not.  Not everything legal is moral!
