Optimal parameters and key variables for effective composting. A summary of the essential compost variables and their preferred ranges for achieving effective composting. Each variable plays a critical role in the composting process. Adapted from [113].
| Variable . | Description . | Preferred range . |
|---|---|---|
| Feedstocks | Organic materials collected for composting (e.g. kitchen scraps, landscaping waste, manure). | |
| BMs | Combined with feedstocks to optimize microbial activity and improve compost texture. | Combined with feedstocks to achieve preferred ranges. |
| Carbon to N ratio (C:N) | Ratio of carbon to N (C:N) in compost feedstock. | 25:1–40:1 |
| Moisture | Water content in the compost pile. | 50%–60% |
| Oxygen content | Adequate oxygen availability within pore spaces for aerobic decomposition. Proper aeration helps maintain oxygen. | >10% |
| Temperature | Optimal temperatures to achieve proper sanitization. | 50–65°C |
| pH | Acidity or alkalinity of the compost. | 6.5–8.0 |
| Bulk density | The weight of compost per unit volume—maintains proper aeration and porosity. | 400–600 kg/m3 |
| Qualitative variables | Color, odor, and texture serve as quick quality indicators. Attention to other variables is crucial. |
