“…Based on the literature, the TS values of OFMSW are generally between 7.9422.1% (Wang et al, 2014), which is similar to the TS measured in this study (Table 1). Cow dung measured in this study had a TS value of 19.0%, comparable to previously reported values between 1519% (Salam et al, 2015).…”

The performance of anaerobic digestion (AD) to process organic fraction of municipal solid waste (OFMSW) can be improved with various pre-treatments. Mechanical pre-treatments, mainly chopping, have shown to be the most economical and relatively effective method to increase contact between the substrate and microorganisms. The purpose of this research was to analyze the effect of OFMSW particle size on CH 4 gas formation in a laboratory-scale Biochemical Methane Potential (BMP) assay. The research was conducted for 35 days at a temperature of 35°C with three sizes of OFMSW co-digested with cow manure. OFMSW with particle sizes of 1013 mm, 4.7610 mm, and 24.76 mm produce CH 4 gas with an average of 114.7+14.7 ml, 101.7+0.5 ml, and 110.9+10.8 ml, respectively, while methane yield was 0.277 L CH 4 /g VS, 0.208 L CH 4 /g VS, and 0.229 L CH 4 /g VS, respectively. Particle size is more likely to have an influence on the hydrolysis and acidogenesis processes, as demonstrated by the significant difference of VFA value, but not on the biogas potential. Particle sizes of 1315 mm produce 19.25 mg VFA/L, while the size range of 24.76 mm produces 118.1 mg VFA/L.

“…Abundant volatile fatty acids accumulated in the initial stage as hydrolysis reaction proceeded quickly because of vegetable residues addition and acidogens prevailed over the other microbes. The volatile fatty acids could not be consumed quickly, leading to the acidification and system crash [11]. It turned out that co-digestion with vegetable residues need nutrient balance to keep the system stable [12].…”

“…Also, high anammox fractions could be maintained by controlling sludge age higher than 40 days and DO at around 0.2 mg O2 L −1 (Ni et al, 2014). Wang et al, (2014d) highlighted that fruit/vegetable waste (FVW) :…”
