ABSTRACT:
The effects of water content, windrow turning, and passive aeration on curing of co-composted municipal solid waste and biosolids was investigated at the Edmonton Waste Management Centre of Excellence, Alberta, Canada. The static windrow treatments consisted of compost windrows at 45 or 55% moisture content, passively aerated using a woodchips base with and without perforated PVC piping. The turned windrow treatments were turned based on time (weekly) or windrow temperature (60�C), and moisture content was maintained at 45%. Co-compost temperature, oxygen content, moisture content, bulk density, pH, electrical conductivity, volatile solids content, ash content and C:N ratio were monitored over four months. The time required for completion of curing was significantly shorter for turned windrows as compared to passive aeration. Temperature, oxygen content, and carbon and nitrogen contents of each treatment were presented.
