“…However, some contradictory results have also been reported by several researchers [79]. For instance, by using a combined H 2 SO 4 with steam explosion pretreatment, crystallinity index of rape straw was increased by 41-49%, which also coincided 14-53% increase in methane yield [87]. The authors attributed the increased crystallinity index to the degradation of hemicellulose, amorphous cellulose, and lignin.…”

“…Besides the difference in pretreatment technique applied, the variation in their compositions also contributes to these results. Cardboard contains 57, 11, and 18 wt% of cellulose, hemicellulose, and lignin, respectively [54]. Rice straw contains 31, 22, and 13 wt% of cellulose, hemicellulose, and lignin, respectively [29].…”

“…Favorable results have been obtained for co-digesting said substrate and/or applying some pre-treatment. The biogas produced from AD can be converted into biomethane (CH 4 ) and used in heat/power generation [70], and the digestate residue can be used as fertilizer [71][72][73]. The reduction of VS (Fig.…”

“…Generally, a HRT (approx. 15-20 days) is needed to reach an acceptable level of VS destruction and biogas production [73]. Likewise, the enhanced killing of VS in a shorter HRT is likely due to the acidic pre-treatment killing cells and extracellular polymeric substances releasing intracellular and extracellular constituents [74].…”

In Mexico, productive activities related to poultry farming and the sugarcane industry generate large amounts of three byproducts: physicochemical residual sludge, poultry manure, and sugarcane wastes, which have high concentrations of organic matter and lignocellulosic material. Therefore, the objective of the present study was to evaluate the effect of acid pre-treatment, with different doses of acetic acid (2%, 3%, and 4% v.v− 1) and exposure times of 30, 60, and 90 min on the solubilization of organic matter and biogas production in the anaerobic co-digestion of a mixture of agroindustrial wastes (residual sludge, chicken manure, and sugarcane wastes). The biodegradability and biogas production were evaluated by anaerobic digestion for 30 days. Finally, for 90 days semi-continuously, the increase in applied organic load of 1 kg VS m− 3 d− 1 was considered with Δ1 kg VS m− 3 d− 1 every 30 days until reaching 3 kg m− 3 d− 1. Acid pre-treatment with a dose of 4% acetic acid and an exposure time of 90 min improved the solubility and hydrolysis, considered the limiting stage of the anaerobic process, reducing the hydraulic retention time from 19 to 11 d, and increasing biogas yields (Ybio=609 ± 11.7 to 1857.2 ± 7.5 Lbio gVSrem−1) and methane (YCH4 = 426.9 ± 8.19 to 1392.9 ± 5.65 LCH4 gVSrem−1).
