Table 4 Comparison of acidogenic digestion yields using different agro-industrial leftovers
From: Efficient molasses fermentation under high salinity by inocula of marine and terrestrial origin
Biowaste origin | OLR (gCOD L−1 d−1) | Max COD to VFAs (%) | Reference | Notes |
|---|---|---|---|---|
Molasses | 9.81 ± 0.1 | 63.5 ± 3.2 | This study | Average of marine and terrestrial PBBRs |
Dairy | 8.0 | 48.4 | [69] | Includes alcohols |
Olive mill | 13.3 | 66.0 | [70] | Used a PBBR |
Dairy | 4.0 | 59.1 | [71] | Includes alcohols |
Food | 83.3 | 43.4 | [72] | Lower OLR (44 gCOD L−1 d−1) had also lower efficiencies (30.5%) |
Sugar beet | 2.7 | 64.2 | [34] | Chemicals addition |
