How long does sawdust take to decompose?

Sawdust can take from months to years to decompose completely, depending on what it is mixed with in the compost pile. In fact, the ratio of carbon to nitrogen (C to N or C: N) in sawdust can be 200:1 or even up to 500:1!

Can you burn sawdust?

If it’s slightly damp, it will smoke, and if it’s very damp it won’t light at all. Dry sawdust burns wonderfully well—sometimes even with a blue flame—and is entirely smokeless. It does give off some fumes, however, and the room where the stove is in use must be well ventilated.
