“…Overall, these results suggest that supplementation of medium at H 2 production stage is very effective to enhance the production yield using biowastes under unsterile conditions. Here, H 2 production was significantly higher than the previously reported yield of 60.2 l H 2 /kg of feed with enzymatically pre-treated oil palm [4]. Similarly, undefined mixed culture had shown lower H 2 production yield 55.3 l/kg of volatile solids using mixed biowaste consisting of macro-algae (Laminaria digitata) and micro-algae (Arthrospira platensis) [6].…”

Co-digestion of biowastes for hydrogen (H 2 ) production using defined mixed cultures can overcome the high risk of failure due to contamination and imbalanced nutrient status. H 2 production from biowastes-pea-shells, potato peels (PP), onion peels (OP) and apple pomace, either individually or in various combinations was evaluated by hydrolyzing with defined hydrolytic mixed bacterial culture (MHC5) and subjecting the hydrolysate to mixture of defined H 2 producers (MMC6). Co-digestion of OP and PP hydrolysate supplemented at H 2 production stage with GM-2 and M-9 media resulted in 95 and 102 l H 2 /kg of Total solids (TS), respectively compared to 84 l H 2 /kg of TS in control. Upscaling the process by digesting 4.0 l slurry (16-fold) resulted in 88.5 and 95 l H 2 /kg of TS, respectively compared to 72 l H 2 /kg of TS in control. Thus, H 2 production by co-digestion of biowastes could be improved through the supplementation with very dilute medium (0.1 9) and selection of suitable biowastes under unsterile conditions. The overall efficiency can be further enhanced by integrating it with bioprocesses for biopolymers such as polyhydroxyalkanoates and or biofuels like methane production.

“…VFA concentration was determined using high-performance liquid chromatography (HPLC) (Shimadzu LC- 20AD, Tokyo, Japan) following the method of Sitthikitpanya et al [ 49 ]. Hydrogen and methane production were analyzed using gas chromatography (GC) (Shimadzu GC-2014, Tokyo, Japan) [ 49 ]. The hydrogen and methane volumes were calculated using the mass balance equation presented by Zheng and Yu [ 50 ].…”

Background A platform for the utilization of the Chlorella sp. biomass and sugarcane leaves to produce multiple products (biorefinery concept) including hydrogen, methane, polyhydroxyalkanoates (PHAs), lipid, and soil supplement with the goal to achieve the zero waste generation (circular economy) is demonstrated in this study. Microalgal biomass were hydrolyzed by mixed enzymes while sugarcane leaves were pretreated with alkali followed by enzyme. Hydrolysates were used to produce hydrogen and the hydrogenic effluent was used to produce multi-products. Solid residues at the end of hydrogen fermentation and the remaining acidified slurries from methane production were evaluated for the compost properties. Results The maximum hydrogen yield of 207.65 mL-H2/g-volatile solid (VS)added was obtained from 0.92, 15.27, and 3.82 g-VS/L of Chlorella sp. biomass hydrolysate, sugarcane leaf hydrolysate, and anaerobic sludge, respectively. Hydrogenic effluent produced 321.1 mL/g-VS of methane yield, 2.01 g/L PHAs concentration, and 0.20 g/L of lipid concentration. Solid residues and the acidified slurries at the end of the hydrogen and methane production process were proved to have compost properties. Conclusion Hydrogen production followed by methane, PHA and lipid productions is a successful integrated circular biorefinery platform to efficiently utilize the hydrolysates of Chlorella sp. biomass and sugarcane leaf. The potential use of the solid residues at the end of hydrogen fermentation and the remaining acidified slurries from methane production as soil supplements demonstrates the zero waste concept. The approach revealed in this study provides a foundation for the optimal use of feedstock, resulting in zero waste. Graphic Abstract

“…Based on the research from Wantanasak Suksong (18), OPT is capable of mono-digestion with POME as inoculum. This was further supported by Sisrsuda Chaikitkaew (33) where it shows OPT with the inoculum of anaerobic sludge granules has the potential to produce methane. OPT that is in the form of effluent from the production of bioethanol produced a higher methane yield compared to raw OPT.…”

In 2021 Indonesia currently provides 58% of global crude palm oil, resulting in enormous amounts of oil palm wastes. The purpose of this research is to determine which palm oil solid waste has the potential to be used as a substrate for biogas production, and what is the optimum method and parameter to produce an economically viable source of biogas. The method used for this research was by means of literature review, in which the data used were acquired from journals, thesis, reports and research papers. This research evaluates the different energy potentials of different oil palm wastes which are; Oil Palm Fronds (OPF), Empty Fruit Bunch (EFB), Decanter Cake (DC), Oil Palm Trunk (OPT) and Mesocarp Fibre (MF). Which resulted in EFB producing the highest yield of methane (429 mL CH4/g VS) at similar operating parameters and methods. The optimization of methane yield from the substrates were studied using different methods and operating parameters resulting in the highest methane yield of 617 mL CH4/g VS from co-digestion of DC + POME. Although, considering the economic viability; it was found that OPF as the waste from bioethanol production was most preferable, not only producing biogas but also bioethanol. It produced a high methane yield of 514 ml CH4/g VS at lower operating cost.
