Disposing of lumber cuts.
I have burned pine, oak, maple, ash etc. in my wood burning stove for years. As long as it is dry, pine burns just fine, no more creosote than most hardwoods. The issue for creosote is the temperature of the burn, if you turn down the air and burn too cold, you are going to get creosote buildup no matter what you burn. If there is adequate air and a hot fire, no problem. Pine gets a bad rap because it has relatively low heat content per cord, but all wood has about the same BTUs per pound of dry wood. I too use pine ends for kindling, very nice. PT wood needs to be disposed of at the landfill unfortunately.
