I have a large sawmill on the property, and I think it makes more sawdust then dimension lumber. I now get much of my supplies from Amazon.com so I have a lot of big boxes. When in the driest part of summer I fill many boxes with dry sawdust and store them in a connex that is painted dark brown. The color makes it very hot inside, hot and dry, that ensures the sawdust is perfect for starting the woodstove in the winter. I keep a five gallon bucket of this dry sawdust in the cabin that I deposit grease from cooking into, and some table scraps. Makes good fire starter, and I keep a oiler can for oiling machinery, with used motor oil. A few cups of bacon greased sawdust and squirt a few shots of used engine oil, add some kindling, a match. and quick like a bunny jump back in bed for a half hour, till the cabin warms.
