Loss of mass and volume during composting of various feedstocks is an important consideration for compost operation management and facility design. Direct measurements of mass and volume in piles and windrows require specialized equipment and skills that render such measurements impractical for most commercial operations. A study was undertaken to develop a technique for calculating reductions in mass and volume during composting based on the change in concentration of an internal standard and bulk density measurements. Of the various physicochemical parameters investigated, nonvolatile solids (NVS) content proved the most reliable internal standard because of its strong inverse correlation ...
