“…Percentage of total volatile solid of food waste and palm oil waste were not measured in this experiment but in studies carried out by Lalander et al . (2019) and Kaosol and Rungarunanotai (2016) , food waste and palm oil decanter cake had a total volatile solid value of 89.8 ± 4.0% and 87.3 ± 0.4% respectively. BSF larvae fed on fish waste had the fastest development time (11 days), but an overall lowest pre-pupae weight.…”

Malaysia like many other developing countries is facing the challenge of poor waste management. This research was conducted to determine the effect of black soldier fly (BSF) in decomposing food waste, palm oil waste, fish waste and yard waste. The development time and waste reduction efficiency of four different organic materials were evaluated. In this study, BSF larvae were fed with all four types of waste at five feeding rates of 0.25, 0.50, 1.00, 1.50 and 2.00 g larva−1 day−1 with three replicates per feeding rate until the larvae reached the pre-pupae stage. During the study, larval development time, larval mortality, pre-pupae weight and waste reduction indexes (WRI) were determined. Food waste and yard waste achieved the highest WRI of 4.43 ± 0.06 and 0.71 ± 0.01, respectively at the feeding rate of 0.50 g larva−1 day−1 while palm oil waste and fish waste attained the highest WRI values at feeding rates of 1.00 g larva−1 day−1 (1.89 ± 0.02) and 0.25 g larva−1 day−1 (3.75 ± 0.24), respectively. The results showed that both variables significantly influenced the bioconversion process, but waste reduction efficiency was the most influential element.

“…The pretreatment of DC was done in different methods. Based on the research by Thaniya Kaosol (30), the DC that has gone through oven pretreatment produced a higher methane yield compared to unpretreated DC by around 25%. This was further supported by Chonticha Rongwang's research (32) as seen in table 2.4.2, showed that the use of ozone pretreatment increased the methane yield by around 24 -52 % and thermal pretreatment increased by 3% -9% compared to untreated DC.…”

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.

BACKGROUND: The potential of methane production from high solid anaerobic digestion (AD) of oil palm decanter cake (OPDC) in a laboratory-scale modified solid inclined (MSI) reactor was investigated. The OPDC was pretreated with liquid hot water (LHW) before being fed to the MSI reactor which operated under high solid content (21% total solids, TS) with leachate recirculation once a day at ambient temperature. The result was compared to the non-pretreated OPDC. The performance of the MSI reactor was evaluated in term of the percentages of solid reduction, methane production rate and yield including removal of organic solids (lignocelluloses and oil and grease). The process stability was also monitored. RESULTS: Pretreatment of OPDC with LHW (OPDC-P) influenced lignocellulosic materials by increasing decrystalline cellulosefrom 50.6 to 28.9% and partial solubilization by reduction of hemicellulose and lignin from 7.6 to 4.9 and 10.6 to 9.5%, respectively. It was found that the chemical oxygen demand (COD) in OPDC-P was increased from 28.5.9 to 62.95 g.L −1 . The methane yield and rate of OPDC-P from the anaerobic MSI reactor were as high as 411 L kg −1 VS added and 23.8 L d −1 (respectively) within a short time of only 15 days compared to corresponding values for nonpretreated OPDC of 245 L kg −1 VS added and 4.9 L d −1 within 50 days. The MSI reactor had high stability within a pH range of 7-8 and a TVA:alkalinity ratio of 0.1-0.2. CONCLUSION: The anaerobic MSI reactor was able to handle high solid content at 21% of OPDC with high performance and stability within a short incubation time. This reactor could be implemented and promoted to utilize solid waste in the palm oil industry.
