Respirometric assays at fixed and process temperatures to monitor composting process

A static respirometer was built to determine the respiration index (RI) of composting samples. Respiration indices of different sludges were determined at 37 °C (RI₃₇) and at the in situ temperature of the composter at sampling (RIT). Results indicated that both indices correlated well with temperat...
