Composting (also referred to as rotting) refers to the biological process of nutrient cycling in which organic waste is degraded by bacteria and fungi (microorganisms) under the influence of atmospheric oxygen (aerobic). In addition to carbon dioxide, this process also releases water-soluble minerals, e.g. nitrates, ammonium salts, phosphates, and potassium and magnesium compounds, which act as fertilizers. Some of the intermediate products produced during this decomposition process are transformed into humus.
The following conditions are important for the composting process:
- Water content 40-60%
- Material density max. 650 kg/m³
- C/N ratio 30:1
