“…A drying temperature of 63 ±3 °C led to the higher methane productivities for each different HFW sample. In addition, the PRO and FAT samples exhibited more methane than the MD samples, at the same drying temperature, as expected since the methane potential of the protein and lipidrich fraction of organic waste is generally higher (Alibardi and Cossu, 2015) and (Nielfa et al, 2015). The same trend was observed at the different types of HFW, which were not dried at the household dryer.…”

Household food waste management and treatment has been recognised as a significant issue worldwide and at a European Union level. Source-separation of household food waste following drying at source presents a viable solution to this problem. The present research aims at investigating the effect of drying of model household food waste at different temperatures (i.e. 63 ±3 °C and 83 ±3 °C) on its biochemical methane potential. The drying process was carried out using a prototype household waste dryer. The model sample consisted of 77%w/w vegetables and fruits (48%w/w and 29%w/w, respectively), 12%w/w pasta/rice, 6%w/w meat and fish, 3%w/w bread and bakery and 2%w/w dairy. Moreover, drying at the same temperatures was applied for two household food wastes samples with different composition, in order to assess the influence of the samples’ composition on both the drying process and the methane generation. For all temperatures used, the higher %w/w mass reduction was observed for model waste (MD) (67.39%w/w and 75.79%w/w for 63 °C and 83 °C, respectively), then for rich-in-protein content (PRO) (66.18%w/w and 69.73%w/w for 63 °C and 83 °C, respectively) and finally for rich-in-fat content (FAT) samples (54.35%w/w and 66.31%w/w for 63 °C and 83 °C, respectively), which confirmed the effectiveness of the drying process. The biochemical methane potential experiments have confirmed that the substrate produced the highest methane yields was the FAT, producing 524.25 ±2.86 L CH4 kg-1 volatile solids.

“…Logistic function (LF) depends on the initial exponential increase that fits the global biogas production. This model assumes that the rate of biogas production is proportionate to the volume of gas already produced, the maximum production rate, and the maximum capacity of biogas production [ 23 ].

Equation terms have same meaning as explained in ( 3 ).…”

The anaerobic batch test (45 days at 37°C) was performed to describe the effect of thermal pretreatment at moderate temperatures (60, 80, and 100°C) over durations of 10 and 20 minutes on the enhancement of biogas production using hotel food waste from city of Jaipur, India. The results showed that the total cumulative biogas production with thermal pretreatment (100°C, 10 minutes) was 41% higher than the control. Also, this alternative gets first rank using multicriteria decision making model, VIKOR. This outcome was obtained due to the enhancement of degradation of organic compounds such as protein and volatile solids that occurred in the linear trend. Modified Gompertz and Logistic models were used to study the effect of different pretreatment parameters on lag time and biogas yield. Scanning electron microscopy and Fourier transform infrared spectroscopy were also employed to investigate the effect of thermal pretreatment on the physiochemical properties of food waste.

“…The specific biogas yields for the component of MSW, such as fruit, vegetable and yard wastes from different seasons, were between 360 and 620 mL/g VS for mono-or co-digested systems (Korai et al, 2018). The reported specific methane yields for meat/fish and paper waste were 293 ± 3 mL/g VS and 217 ± 5 mL/g VS, respectively (Nielfa et al, 2015).…”

This study investigated the effects of organic loading rates (OLRs) and temperature on the performance and stability of anaerobic digestion treating the organic fraction of municipal solid waste (OFMSW) in a semi-continuous mode. Furthermore, a preliminary energy analysis was conducted to determine the optimal application parameters for anaerobic digestion of OFMSW. Results showed that the maximum achievable OLR was 9.00 g VS/(L•d), with a volumetric biogas yield of 4.03 L/(L•d) and 4.31 L/(L•d) for mesophilic and thermophilic systems, respectively. However, the preliminary energy analysis showed higher energy conversion efficiency was achieved for the system operated at an OLR of 7.50 g VS/(L•d). The system operated at the thermophilic condition had a higher total energy due to more electricity and heat energy generated than the mesophilic one. Therefore, the recommended operating conditions for the anaerobic digestion of OFMSW is an OLR of 7.50 g VS/(L•d) and thermophilic condition. Based on the annual yield of OFMSW in China, the estimated net output energy was 69970.61 GWh per year.
