“…Organic Matter → CH 4 + CO 2 + H 2 + H 2 S + NH 3 (4) In general, when 1 g of COD is stabilized, 0.35 L of biogas is produced at 1 atm and 0 °C, while 0.40 L of biogas is produced at 35°C [15]. In this experiment, the ratio of initial VS/TS of samples containing FBs was in the range of 0.68-0.78.…”

“…In addition, rice bran has the advantage of reduced cost relative to other external carbon sources and recycled resources because it is waste of milling rice [26]. According to previous studies, about 70% of the methane produced in anaerobic digestion comes from acetic acid and can have a significant effect on biogas production and sludge reduction in the anaerobic co-digestion process [3,12,15,18,21]. The experiments showed that the pH was 3.2 at 5 d of acidogenic fermentation when using rice bran ( Fig.…”

“…FBs from large factories are mainly recycled into fish meal and feed [19]. However, most FBs treated in homes or small factories take the form of food waste [2,15]. FBs contain large amounts (approximately 81-92%) of various organic matter, including 62-79% moisture, 7.0-12.5% nitrogen,…”

“…Thus, FBs have great potential to convert to biogas through anaerobic digestion. Several previous studies have reported that combined digestion with fish waste and sewage sludge has significant potential for biomethane production, while studies on anaerobic digestion of fish wastes have shown biomethane production potentials ranging from 0.2 to 0.9 (CH 4 m 3 /kg VS) [15,19,20].…”

The purpose of this study was to investigate the effects of acidogenic fermentation broth with rice bran (RFFB), tap water (TFFB), or raw fishery by-products (FBs) on sludge reduction and biogas production in an anaerobic co-digestion process. Acidogenic fermentation of FBs with rice bran was faster and produced more volatile fatty acids than that with tap water. Reduction efficiencies for chemical oxygen demand, volatile solids, and total solids were highest in RFFB. In the kinetic analysis, λ (d), which represents the duration of the lag phase, was shortest with RFFB (1.09 d) and highest in sewage sludge (8.86 d). As the loading amount of volatile solids and chemical oxygen demand increased, the amount of cumulative biogas also increased. Amount of produced methane and energy recovery were highest with RFFB (5.71 kWh). Anaerobic co-digestion of FFB and sewage sludge allowed reduced sludge and recovered energy using the discarded waste as an organic carbon source.

Determination of long-chain fatty acids in anaerobic digester supernatant and olive mill wastewater exploiting an in-syringe dispersive liquid-liquid microextraction and derivatization-free GC-MS method

et al. 2021

Long-chain fatty acids (LCFA) are commonly found in lipid-rich wastewaters and are a key factor to monitor the anaerobic digesters. A new simple, fast, precise, and suitable method for routine analysis of LCFA is proposed. The system involves insyringe-magnetic stirring-assisted dispersive liquid-liquid microextraction (DLLME) prior to gas chromatography-mass spectrometry (GC-MS) without a derivatization process. Calibration curves were prepared in an ethanol solution (R 2 ≥ 0.996), which was also useful as disperser solvent. Hexane was chosen as the extraction solvent. Several parameters (pH, ionic strength, extraction solvent volume, stirring time) were optimized in multivariate and univariate studies. Limits of detection (LODs) were found in the range 0.01-0.05 mg L −1 and good precision inter-day (RSDs≤7.9%) and intra-day (RSDs≤4.4%) were obtained. The method was applied to quantify LCFA in supernatants of anaerobic digesters and olive mill wastewaters (OMW). Palmitic, stearic, and oleic acids were the most abundant fatty acid in the analyzed samples and the relative recoveries for all of them were between 81 and 113%.

The aim of this study was to investigate the estimation and management of fish and shrimp wastes in Bushehr province. Twopart questionnaire including the demographic information, and fish and shrimp waste disposal method were completed for 91 stores and 636 households. The quantity of generated wastes was estimated based on the 3 different Scenarios. In addition, the waste generation factor were calculated for common fish and shrimp species. Results showed the waste generation factor for fish and shrimp equal to 32.67 and 42%, respectively. The total quantity of fish-and shrimp-generated wastes in Bushehr province was estimated to be 29,388 tons per year, of which the quantity of generated waste by stores and by households was 3731 tons per year (16 ton per capita per year) and 8804 tons per year (34 kg per capita per year), respectively. The remaining quantity is related to other unaccounted sectors such as fish industries. Moreover, the biogas production potential from an anaerobic digestion were estimated 2,675,400 m 3 per year, which is equivalent to 16,052 MWh. In addition, the biodiesel production potential was obtained equivalent to 19 kt, which is about 4.2% of the total diesel fuel requirement of the province in 2016.
