Composting material — Windrow area Once the material is placed into windrows it will be monitored for temperature and moisture and turned to ensure that it meets pathogen reduction and vector attraction reduction requirements and VOC reduction requirements. Following the time and temperature requirements, the material will remain in the windrows until it is cured. This stage begins a drop in temperature of the composting piles, and initiates the process of creating mature compost. This phase lasts a few months, and enables the compost to stabilize so that it is beneficial to plant growth. After curing, the material cannot begin composting again and thus is free from any potential odor or vector issues. Overs At the end of the curing phase, the material is run through a trommel screen and the material is separated into fines and overs. The fines are sold as finished compost products, and the overs are either incorporated into the compost or sold to a co -generation plant. If the overs are stored on site, they will be also be stable and will remain on site for well under the six month requirement.
