My wife's distant cousin is making wood pellets right in the same industrial park my shop is in....at first they were making them for oil field absorbent....but now are making them for burning. I've heard they burn OK but don't throw much heat. I'll find out shortly. To my favor, my Tarm HS 4.0 is not finicky at all about pellets....it'll burn just about anything I put in it. However I have the exhaust and water temps logged running my current brand and will see how these do. Right now they are priced at $180 a ton which is reasonable if they work well. My fingers are crossed anyway. Seeing their setup makes me want to give making my own pellets a shot....
