Anyone have experience of bulk sawdust disposal? I'm looking into the possibility of a pelletising press as a way of turning useless sawdust into a storable and possibly saleable pellet fuel. However all the pellet presses I've seen have been huge and expensive, intended for use by a pellet-making plant, rather than just intermittently disposing of waste from a small timberyard.
I also note that meat-packing screw presses are cheap and commonplace S/H, but sawdust pellet presses are anything but. Anyone heard of a DIY conversion process ? I'm expecting that hard-facing the screws would be needed, but a little engineering work is no problem.
