Hello all. This is my first post here, although I've been lurking for a while. I hope to keep searching more than posting but I was wondering about this. Would used lumber (southern yellow pine 2x4, 2x6) be a good source for firewwod to supplement/extend my hardwood supply? Here is my reason for asking. I run heavy equipment, a John Deere 850J LGP recently, for a highway contractror. They build roads and bridges and use a lot of lumber for forms and falsework. They re-use lumber until it is in such small lengths that it is unusable for their purposes. That is generally around 2' long, a perfect size to toss in a stove. They send literally tons of it to their landfill in roll-off dumpsters on a regular basis. It would be easy for me to raid the dumpster, with their permission of course, once or twice a week and bring home the clean pices that would require no additional cutting or removing of nails/concrete to put in my pile at home. So, tell me the reasons why I shouldn't bring this home and burn it. I would probably burn it in the evenings when I first light my fire and then throw on some of my red and white oak/hickory/locust to burn through the night. I don't intend for this pine to be my sole source of fuel. I just hate to pass on free wood, if it is something that is usable.
