A friend of mine has a small sawmill/carpentry business, and has been saving me all of the sawdust that he has been accumulating. I'm getting ready today to go over and pick up about a dozen large garbage bags of sawdust from him. It is only dust from raw wood as he is also a gardener and disposes of the sawdust from pressure treated wood appropriately. My question is how many different ways are there to use sawdust in the garden and around the homestead? Also what ideas are there for turning sawdust into high quality compost?
