Aerobic compost
This process involves converting organic wastes
into compost in aerobic conditions. In aerobic composting, the temperature
inside the compost pile rises rapidly to 70-80 °C within the first couple of
days. First, mesophilic organisms multiply and the pile temperature ranges
between 20-45 °C. Then a few thermophilic fungi and several thermophilic
bacteria carry out the process, raising the temperature of the pile to 65°C or
higher.The final product is dark brown to black in colour and soil-like in
texture. In the process, the amount of humus increases, the ratio of carbon to
nitrogen (C:N) decreases.
