“…The BMP results showed very good agreement between duplicate samples, with a specific methane yield of 0.352 L g -1 VS added. This is equivalent to 25.5 m 3 CH 4 per wet tonne, which reflects the high water content of the material and is fairly typical of literature values [4,9,12]. The semi-continuous trials achieved ~99% of the BMP despite the relatively short HRT, confirming both the rapid biodegradability of the substrate and the BMP results, which showed most of the gas production occurring in the first 10 days (Figure 6).…”

“…The use of the modified trace element recipe with the inclusion of tungsten and higher concentrations of other known essential elements allowed stable operation at OLR higher than those achieved in previous studies using similar FVW feedstocks [4,9,34,35]. Table 3 and Figure 6 show the cumulative net specific methane production over a 28-day test period for the VW feedstock and YE used in the first semi-continuous trial.…”

“…A number of studies, however, have indicated problems and limitations in the anaerobic digestion of this material. Knol et al [4] reported the results of a 90-day experiment using a mixed waste of apples, asparagus, carrots, green peas, French beans, spinach and strawberries from a canning factory. Digestion was in mesophilic conditions at organic loading rates (OLR) between 0.80-1.60 g volatile solids (VS) L -1 day -1 with a 32-day hydraulic retention time (HRT), and produced average biogas yields of 0.30-0.58 L g -1 VS. Digestion of some of these materials showed instability, and in these cases remedial measures were introduced which included alkali addition, feed interruption and mixing with a nitrogen-rich supplement.…”

Strategies for stable anaerobic digestion of vegetable waste

International trade and the market demand for pre-prepared agricultural produce is not only increasing the total quantity of waste agricultural biomass but also centralising its availability, making it potentially useful for energy production. The current work considers the suitability of vegetable trimmings and rejects from high-value produce air-freighted between Africa and Europe as a feedstock for anaerobic digestion. The physical and chemical characteristics of a typical mixed vegetable waste of this type were determined and the theoretical energy yield predicted and compared to experimentally-determined calorific values, and to the energy recovered through a batch biochemical methane potential test. A semi-continuous digestion trial was then carried out with daily feed additions at different organic loading rates (OLR). At an OLR of 2 g VS L -1 day -1 the substrate gave a methane yield of 0.345 L g -1 VS added with VS destruction 81.3%, and showed that 76.2% of the measured calorific value of the waste could be reclaimed as methane. This was in good agreement with the estimated energy recovery of 68.6% based on reaction stoichiometry, and was 99% of the biochemical methane potential (BMP). Higher loading rates reduced the specific methane yield and energy conversion efficiency, and led to a drop in digester pH which could not be effectively controlled by alkali additions. To maintain digester stability it was necessary to supplement with additional trace elements including tungsten, which allowed loading rates up to 4 g VS L -1 day -1 to be achieved. Stability was also improved by addition of yeast extract (YE), but the higher gas yield obtained was as a result of the contribution made by the YE and no synergy was shown. Co-digestion using card packaging and cattle slurry as co-substrates also proved to be an effective means of restoring and maintaining stable operating conditions.

“…Various wastes are utilized for biogas production including animal and industrial wastes (Bolzonella et al, 2003;Thanikal et al, 2014), food processing wastes (Park et al, 2008), and vegetable wastes (Ranjitha et al, 2014;Viturtia et al, 1989;Misi & Forster, 2002;Velmurugan et al, 2011;Knol et al, 1978). Vegetable wastes, due to their high nature of biodegradability (Viturtia et al, 1989;Misi & Forster, 2002) and moisture content (75 -90%) seemed to be a good substrate for bio-energy recovery through anaerobic digestion processes (Velmurugan et al, 2011).…”

Biogas production is a clean, low carbon technology that is useful for efficient management and use of organic waste. Composition of organic waste plays an important role in biogas production. In the present investigation, fuzzy indicator modeling has been utilized for assessing 10 compositions of organic waste. Evaluation of these compositions was carried out using individual fuzzy indicators with two variables: "Methane" and "Hydrogen sulfide". Alternative ranking of variants of composition is given.

Number of crop residues generated at large amount in agriculture can be utilized as substrate in methane production by anaerobic digestion. Greenhouse vegetable crop cultivation that adopting intensive agricultural system require the heating energy during winter season, meanwhile produce waste biomass source for the methane production. The purpose of this study was to investigate the methane production potential of greenhouse vegetable crop residues and to estimate material and energy yield in greenhouse system. Cucumber, tomato, and paprika as greenhouse vegetable crop were used in this study. Fallen fruit, leaf, and stem residues were collected at harvesting period from the farmhouses (Anseong, Gyeonggi, Korea) adopting an intensive greenhouse cultivation system. Also the amount of fallen vegetables and plant residues, and planting density of each vegetable crop were investigated. Chemical properties of vegetable waste biomass were determined, and theoretical methane potentials were calculated using Buswell's formula from the element analysis data. Also, BMP (Biochemical methane potential) assay was carried out for each vegetable waste biomass in mesophilic temperature (38℃). Theoretical methane potential (B th ) and Ultimate methane potential (B u ) off stem, leaf, and fallen fruit in vegetable residues showed the range of 0.352∼0.485 Nm ) of crop residue may be highly influenced by biomass yield which is mainly affected by planting density.
