What to do with all the sawdust ?

Recommended Posts

I have been working on a new project over the past month on a firewood processor, i have a few improvements to finish off and i think it will work really well for us, however i can see that we are producing lots of sawdust and very quickly !, now this is chainsaw bar as opposed to tct so there is slight oil from chain lube, it’s about 30-40 % moisture so i think that makes briquettes more difficult, my current thinking is to bag/ box up and try and sell as oil absorption matter, be interested to hear any other possible uses ?

You'll need to dry it for oil spill. I think the mixture of molecules making up wood have bits which are hydrophilic (attract water) and bits elsewhere that are oleophilic (attract oil).

 

If you heat them a bit more  (torrefication) the  mixture is modified so they become hydrophobic and oleophilic.

 

Tom Read patented a torrefied wood product called seasweep for absorbing oil spills at sea but how he  made it he kept secret. He claimed it would float indefinitely being hydrophobic it didn't re absorb water.

Add extra (used engine oil?, perhaps better not actually clearly specified ) oil, sandbag it up and sell as logwood gasifer fuel, bags go in unopened.

Or use as such to run a burner/boiler of your own?

Or switch to a Scandnavian type biodegradable  chainsaw bar oil, and bobs yer uncle marketing wise? (the simplest solution?)

Flog it as bio activated carbon rich compost additive, or somesuch(having just wheel loads of chainsaw sawdust to our couple of compost heaps.)

P.S.
Photos of the completed machine please.

Cheers

You are enormously knowledgeable.

Cheers guys some great suggestions there, especially like the waterproof oil absorption material, very clever in the development of the concept and then superb application, very interesting

We just mix all ours with the woodchip that goes in the boiler. Either tip in with the bucket or blow it straight in through the contractors heizohack

We just started bagging ours to sell as animal bedding, it's not big money and has to be stored because sales are inconsistent but it saves dumping it and every little helps.
