It depends what you do with it.

 

If you split and neatly stack one artic load (anywhere from 22 - 26T dependent on water content) then you'll end up with around 30m3 and usually 1m3 of sawdust.

 

If you split and loose bag one artic load then you'll be bagging lots more air and end up with around 45m3 and around the 1m3 of sawdust.

 

Volumes will vary dependent upon the density of the wood. Pine would yield 10% more volume per ton weight at the same moisture content than oak. There is plenty of information online relating to the density of various wood species.

 

I seem to produce at least 2m3 of sawdust from 25T load! Earlier in the year I got 2 loads of relatively fresh pine. I got around 40m3 loose per 25T.

I process using a circular saw. Maybe you chain cut which would account for twice the thickness of a cut resulting in twice the waste?

 

Im3 sawdust is like loosing over 2m3 of bagged logs so the less waste, the more you have to sell.

That is really interesting and I guess its kind of obvious too, now I think about it. If ever I get a new processor I will have to factor that into my costings!

I don't suppose anyone knows of a conversion rate of weight (tonnes) to volume (m3) for sweet chestnut when green (freshly felled)? I am looking through my many forestry books but have found nothing as yet, nor have I on internet searches, so I hoped by throwing it out there to the knowledgeable people on this forum, I might get somewhere.

 

Its the age old problem of seller wishing to sell by volume but buyer wishing to buy by weight.

Depends on time of year as well spring summer felled wood is significantly heavier than winter felled. A wagon "load" is a subjective measurement based on the what the driver feels is a load my advice would be never accept a load unless hes been to the weigh bridge.
