Can finished compost be used as a partial or full substitute for fresh sawdust in the primary bin?
Experience to date indicates that up to 50 percent of the fresh sawdust requirement may be fulfilled using finished compost. It is unlikely that long-term viability of the process could be maintained if no fresh sawdust were used, as the source of carbon would eventually be exhausted. Advantages of recycling finished compost include: less fresh sawdust required, active bacteria and heat contained in finished compost and less finished compost to haul for land spreading.
