Treated wood burning

Just a word about 'tanalising'.

I had to look into this a few years ago when I was buying wood for raised beds in which I grow vegetables. I was concerned the arsenic, which I'd repeatedly read was used in the tanalising process, might contaminate the soil.

I contacted the head office of a major timber retailer and was assured that the old tanalising method had been banned and that arsenic was no longer being used in the preserving process.

This doesn't mean it's safe to burn, not least because scrap timber could well have been treated before the ban, but it seems sensible to get current state of play more widely known.

I am under the impression that now a days Tanalised wood is preserved with some sort of copper chemical - hence the green colour.

Ahh a company in West Yorks have confirmed this

Pressure Treated Timber
TANALISED pressure treated timber has been impregnated with TANALITH E, a waterborne product based on copper triazole technology.

I didnt think the UK used arsenic anymore

It is mucky - Tanalith was the original stuff from the 1930s, which used copper, chrome and arsenic. Tanalith E is the modern formula which dispenses with the chrome and arsenic and is a lot less toxic in the environment.
