1. Incoming materials
Good sorting avoids contaminants and enables an appropriate blend.
2. Blend balance
Carbon-rich structural materials and nitrogen-rich materials complement each other to support biological activity.
3. Moisture
Too little water slows the process; too much removes air and favors undesirable conditions.
4. Oxygen and turning
Aeration supports aerobic decomposition and limits compacted zones.
5. Temperature and maturity
Temperature monitoring helps read biological activity. Maturity is checked before screening, storage and use.
