Yes. It is best to mix sawdust with other products being composted, as well as aged sawdust. Sawdust has a very high carbon-to-nitrogen ratio, so additional nitrogenous materials will be needed to help break it down. Examples of high nitrogen material for composting are: grass clippings, vegetable scraps, and live stock manures.
