Abstract
The biodrying process was carried out in a bioreactor with a capacity of 240 dm3 . The research utilized digested sludge from a sewage treatment plant and an organic fraction of municipal solid waste. The dry mass, dry organic mass, temperature, and respiration index of the dried material were determined during the biodrying process. Because of the waste biodrying process for ten days, the amount of moisture removed was 51.7%. The greatest activity of microorganisms in the waste was on the fourth day of the process, when the temperature reached the maximum value of 58°C in the top layer of waste in the middle of the bioreactor.
