uses for a lot of unseasoned sawdust

[flames]

Hi offgridchris, interesting to hear that you and other people have this problem too. I don't have this problem with milling sawdust as I tend to mill on site/at timber yards where the site bonfire/chip pile takes care of it. But at home I produce a lot of wood turning chips that I mostly get rid of in the 'garden waste' bin and also my wood burner, neither of which are great solutions.

 

I can’t believe that there isn’t a small scale/domestic solution to this problem as a lot of home wood workers, particularly turners, have problems getting rib of their waste.

 

I've come to the conclusion that to make use of the waste chips/sawdust (for warmth anyway) it must be dry (~15%) to burn well or briquette etc.

Double-drum Sawdust Stove

 

I'm considering building something like this, but making it a 'twin tub' (is this what you where thinking) while one firebox is burning then the other is drying, when the lit firebox burns out you recharge it with wet chips and light the other firebox. This way it only requires loading with chips/sawdust.

 

Anyone seen something like this? I know this is done in commercial mills.

Accumulate a good pile and then sell the whole lot into the Biomass market... should make somewhere in the region of £20 a ton at the moment.
