Abstract

Composting is the process of organic biological decomposition in aerobic and controlled conditions. Many factors can affect the composting process, and almost all are related. Some factors that majorly affect the composting process also influence the stage or direction of the process. This paper focuses on the technical factors that affect the composting process’ achievement of the thermophilic phase, particularly in a closed reactor system. At the same time, this paper will be discussed about the benefits and comparison between close reactor system and the conventional pile method. The technical factors that are discussed in-depth in this mini review paper are the rotation or turning frequency, aeration rates, and the initial moisture of the compost mixture for closed reactor composting system. All three factors significantly cause increased thermophilic temperature in the closed reactor. Basically, there are 3 important phases in the composting process, which are the mesophilic phase, thermophilic phase, and maturation phase. In the composting process, it is crucial that the thermophilic temperature is reached. By increasing the thermophilic temperature, the number of thermophilic microorganisms also increases, causing the rapid degradation of bio-waste.
