Curious to know if anyone here has worked in a sawmill, or just knows the answers to a couple of questions- 1. What do sawmills generally do with sawdust? Is there a market for it, or is it just a waste product for them? If so, how might they dispose of it? 2. What do sawmills do with the mill ends generated from cutting lumber? Again, is there a market for them, or are they considered waste?
