I thought I read on here in one of these threads that you could place sawdust in a brown paperbag and burn it with no problems. I have like 2 inches of sawdust sitting around my table saw, thought I would scoop it up and burn it. Please advise...
 
sure, makes a great firestarter, im assuming that its clean wood that is not toxic, and im also assuming you would not just add a firebox full of paper bags and saw dust... it should be used as a firestarter are in small amounts, its not like your going to get any kind of burn times out of it, just a small blast of heat,.
 
Hey why not compress the sawdust into firelogs. There is a company that does that.

those are made out west from fir and pine sawdust imagine how good they would be made from hardwood sawdust!

Business idea maybe?

I saved some of the sawdust from my hickory floors and jarrah (E Australia, talk about 'hard'!) decking. I load up multiple small depression areas with old paraffin and the hardwood sawdust in a cheap muffin pan, heat for 20 or so minutes at 250* and, presto, small muffin sized firestarters emerge. They store easily in a box in the pantry.

They light quickly, burn intensely for about 5 minutes never yet failing to start the fire, are cost effective, contain less calories than cookies and make a mess in the kitchen.

Besides sawdust, I 'recycle' cardboard tubes inside empty TP and paper towel rolls the same way.

And then there's the dedicated sawdust stove, easily made out of a paint can. Google "sawdust stove" and you will find an example like this:

There was also some company that manufactured sawdust stoves, but I'm not sure they're in business now, maybe because they're so easy to construct yourself.

That's very interesting. I actually live not too far away from a little sawmill.... the owner has said I can take whatever sawdust I want. I wonder if there's a way to make these "jumbologs" myself?
 
on that site they dry the sawdust to around 6% moisture content the it is compressed into the log form under extreme pressure.
1 log generates alot of btu's and burns for a long time. There is no adhesives of any kind added very similar to making wood pellets except it pressed into alot larger form.

I would think with a heavy cylinder and a 20 ton shop press you could fill the cylinder and press the crap out of it!

maybe? It would be interesting to try if one had the spare time!

Check this out, "Briquettes from Wood Residue," a 1964 paper from the Dept. of Agriculture.

And there's this high school project to produce a viable machine for $600. I don't know what happened to it:

And here's a forum thread in which someone who has a 20 ton hydraulic press is wondering whether it will compress sawdust into logs. The whole thread is about home-made sawdust logs:

That might have been me. I have a small wood shop and end up with more sawdust and shavings than I know what to do with. I took a bunch of shavings from air dried walnut and bagged it and used it as firestarter. shavings from the planer and jointer work great. I have swept the floor once or twice when it had lots of shavings on it so I got some sawdust as well but I don't know how well it would work if it was just sawdust. If you didn't try to pack it I suspect it would be fine but packing it down tends to deprive it of air.
Handed the wife one of these bags tonight while I was trying to finish my Honeydo list. She got the fire going nicely.
