I've always said that growing stuff, then burning it again, is futile as
a way to reduce carbon emissions. What you need to do is grow stuff,
then capture it.

Agreed. The "green aura" around biomass is the road to hell.


the mixed messages and lack of leadership surrounding wood-burning -
particularly domestic wood-burning.

What's your issue with domestic wood-burning. Pollution or CO2. I have a
wood-burner, but don't consume anything other than waste wood that I'd
otherwise take to the tip, and then they'd chip it and burn it... The
stove sees to consume any smoke that less sophisticated grates might
generate.


Particulates. Again the green aura around wood burners is very
misleading. I don't dispute that you do the right thing, Roland - but
the majority do not. Government advisory approval of good burners is a
start but how that as well as the use of low particulate rate fuel is to
be enforced is just not being addressed.

And the only ideas eventually adopted will need to be draconian.

industry.

JOI what is the source of your waste wood,are you lucky enough to have a
source of offcuts from a carpentry business like I once had ? I It saved
them paying to get it taken away as waste.
That stopped when the business closed and I have long since moved anyway
and have to use harvested wood from a local source near the village
subject.
A lot of small businesses that produce waste wood will no longer
supply such offcuts to a casual user
as technically it is waste and whoever carries it off should have the right
licences to deal with it and more recently with rise of the pelleted wood
as fuel such clean waste has a value and will be collected commercially.

The rise of urban trendy woodburner has also lead toa type of user who
thinks they are being green by scavenging builders skips and sites for
waste wood, I would never find enough that way* but
I suppose in a busy city it is possible . Unfortunately their green
credentials go up the chimney along with the noxious substances that such
wood which has been treated with various preservative treatments , paint
and varnish coatings to stop it rotting. CO2 is quite benign compared to
what comes off some of those.

*Though they won’t have access to the odd tree that gets blown down in an
adjoining field.
I also get a little bit from a local Spaniel who has a penchant for
collecting bits of fallen branch two or three times the dogs length on its
morning walk in nearby woods, not many mornings go by without
such a branch about 2� diameter 3ft long being dropped by the gate. Once
dried it makes kindling
and the cost is an occasional biscuit.

JOI what is the source of your waste wood,

It's partly a big pile of old fences inherited (as a pile) from the
previous owner. And partly DIY wood offcuts I've been carting around for
years and have finally decided I'm never going to have a use for.
