Happy Friday to all,
I'm after a bit of guidance thats probably more akin to envirnmental than H+S but here goes...
What are the implications of burning wood that has be "de bugged" either by methyl bromide or phosphene? Heard allsorts of stories re rotting chimneys, producing cyanide and/or sulphuric acid etc but I thought this was only as a result of burning tanalized wood?

Soon be beer time...

The EA will view this as disposal so you will have to have the necessary permits etc in place. Also if the burning produces dark smoke this is also an offence.
Regards
David

I fully understand the EA's view on it, and at present we do dispose of approx 5 tonnes per week via recycling. However, there are lots of people who keep enquiring about wehether they can take some home to burn in their log burner or grate. I'm not really fussed if they do or not, but have heard "urban myths" about treated wood damaging the chimney?
The wood is treated in the country of origin under quite strict proceedures and I've tested for the presence of MB when its here which proved negative, so why cant we burn it?

Pedigree tonight I think, with a bag of scratchings!!

The one thing you cannot do is say yes. If you aknowledge that your waste is being disposed of in a manner such as this then technically you are in breach of the Duty of Care.
If you do not know that it is happening then I suspect that the problem will not arise. Of course I am not advocating a deliberate evasion however!

As this all stems from EU directives, perhaps some of our colleagues from Greece, Italy, Spain, Romania, Bulgaria, Poland, etc. might care to talk us through their approach.

In respect of your posting I recall reading in the environmetal acts that only wood produced on site (e.g. old fencing taken down or brush cutings etc) could actually be burned on the site, every thing else had to be removed!
Can't recall where or in what exactly I read this but know it was definitely there...

Hi - please be aware that any burning of any waste on site is banned unless you have a licence from a the L A.

Morning Holmezy.
Cracking question. I wish I knew the answer.
A lot depends on:
Where the wood is being burnt.
The temperature of combustion. The higher the temperature the better.
Chemical reactions and by-products.
The darkness of the smoke produced.
The smell.
Any ash produced.
Where it is being burnt, (if its being taken home from work, then "in theory" there is a breach of waste regulations).
The last poster (DH) is slightly wrong and this may answer S Nagle's statement.
You MAY be permitted to burn certain wood or plant wastes WITHOUT an environmental permit or a waste management licence, PROVIDED that:
1. The wood or plant waste was produced as a result of demolition work.
2. you burn the material on the land where it was produced.
3. You stick to quantity limits imposed over 24 hour periods.
You will USUALLY need to register an exemption with your environmental regulator for this activity.
That's from the NETREGS. Re construction and demolition. April 2008.
Trouble is, there are a lot of ifs and buts and pots and pans in there and its irrelevant to your question. A keyword to note however is "untreated wood".
As for damaging chimneys, the only thing that I can think of is sooty or acidic deposits.
As soot is actually flammable, "sticky" soot may lead to chimney fires. Or if the chimney or lining is galvanised there could be a problem with acidic deposits reacting with the metal and/or coatings, especially if combustion temperatures are low. You could get into problems associated with leaks of carbon monoxide, if exhaust systems begin to fail.
I wish I could help more.
I would go for continued disposal as re-cycling and claim smarty points for being eco-friendly.
Take care.
Mark
