🌾 Feed Types Active in Operations Form
Standard feeds are auto-added from Primary Feedstocks above (🔗 primary badge). Add additional non-standard feeds here (e.g. FYM, food waste, molasses).
📊 Theoretical Reference Values — Mesophilic 35°C CSTR (approximate)
⚠ Mesophilic CSTR basis (32–38°C, continuous). These are conservative in-reactor yields — not BMP batch values. Thermophilic operation typically yields 10–20% more. Actual yield depends on HRT, OLR, feedstock freshness and pre-treatment.
| Feedstock | VS% (wet) | C:N Ratio | Yield Nm³/tVS (mesophilic CSTR) |
CH4% | Notes |
|---|---|---|---|---|---|
| Press Mud | 23–27% | 45–55 : 1 | 270–340 | 60–63% | Sugar mill filter cake; lignocellulose limits hydrolysis at mesophilic |
| Poultry Manure | 18–22% | 5–10 : 1 | 200–290 | 58–62% | NH₃ inhibition at mesophilic reduces realised yield; keep VS share <30% |
| Cow Dung | 11–15% | 16–22 : 1 | 140–210 | 55–58% | Already partially digested in gut; lower hydrolysis potential |
| Corn Steep Liq. | 4–6% | 3–6 : 1 | 200–290 | 60–64% | Lactic acid readily degradable; dilute with high-C feeds to avoid NH₃ |
| Spent Wash | 6–10% | 18–28 : 1 | 160–240 | 55–60% | High sulphate → H₂S; melanoidins resist biodegradation |
| FYM / Farm Waste | 12–18% | 20–35 : 1 | 110–190 | 54–58% | Variable; straw & husk lower digestibility at mesophilic |
| Food Waste | 15–25% | 10–20 : 1 | 260–420 | 60–68% | High yield; acidification risk at high OLR — co-digest |
| Molasses | 60–70% | 30–50 : 1 | 240–330 | 58–63% | High sugar; dilute heavily; sulphate from stillage is a concern |
⚠ Ideal C:N for anaerobic digestion: 20–30 : 1. Below 15 → free ammonia inhibition. Above 40 → N deficiency / reduced methanogenesis.
