“…Additionally, for the codigestion of hay with soybean processing waste at 25:75 ratio under solid-state AD process, the methane yield was 258 L/kg VS, which is 50% and 148% higher than the amount obtained by each substrate individually [117]. Co-digestion of barley straw with pig manure produced 233.4 L/kgVS methane, but it produced only 192 L/kg VS methane when it was codigested with cow manure [167]. Corn stover and dog food at an equal ratio (1:1) produced a methane yield of 304.4 L/kg VS, which led to an increase of 129% compared to corn stover alone and 9% compared to dog food digestion alone [116].…”

Anaerobic digestion (AD) has become extremely popular in the last years to treat and valorize organic wastes both at laboratory and industrial scales, for a wide range of highly produced organic wastes: municipal wastes, wastewater sludge, manure, agrowastes, food industry residuals, etc. Although the principles of AD are well known, it is very important to highlight that knowing the biochemical composition of waste is crucial in order to know its anaerobic biodegradability, which makes an AD process economically feasible. In this paper, we review the main principles of AD, moving to the specific features of lignocellulosic wastes, especially regarding the pretreatments that can enhance the biogas production of such wastes. The main point to consider is that lignocellulosic wastes are present in any organic wastes, and sometimes are the major fraction. Therefore, improving their AD could cause a boost in the development in this technology. The conclusions are that there is no unique strategy to improve the anaerobic biodegradability of lignocellulosic wastes, but pretreatments and codigestion both have an important role on this issue.

“…Daily biogas production and methane content b. Cumulative biogas and biomethane production Figure 2 Daily biogas production, methane content, and cumulative biogas and biomethane production during AD of SMS The time required to produce 80% of the maximal biomethane production (T 80 ) is used to evaluate the digestion performance of AD processes [45] . The T 80 for SMS was 25±1 days and the shorter digestion time (10.7% shorter than that of the control test in previous studies) [46] could be associated to delignification of the substrate by mushroom cultivation.…”

This study proposed an integrated process of Pleurotus ostreatus cultivation, anaerobic digestion of spent mushroom substrate (SMS), and fertilizer value evaluation of digestate for achieving multiple products and full utilization of nutrients in rice straw. The results showed that the cultivated mushroom yield from rice straw was 401 g/kg TS. Biomethane yield obtained from anaerobic digestion of SMS was 133.0 mL/g VS. The fertilizer value of the SMS based digestate reached the national standard of fertilizers from organic sources in China. Substance conversion of rice straw during the integrated process revealed that the process could achieve the full utilization of nutrients in the substrate. Energy assessment indicated that the process had the viability to be applied. Therefore, this study provided a feasible strategy to set up a complete recycling agricultural ecosystem.

“…Agricultural residues available for the second generation biofuels include various crop and plant residues, fruit and vegetable waste, grass, forest residues, livestock manure, and many other byproducts of various agricultural processes (Paudel et al 2017). The anaerobic digestion (AD) of agricultural residues is an attractive second-generation technology with the potential of environmental and economic benefits (Wei et al 2015).…”

This study investigated the effects of nutrients supplementation during codigestion of maize silage and cattle slurry. Batch anaerobic biodegradability tests lasted 20 days under mesophilic conditions, and an organic loading rate of 5.0 g VS (volatile solids)/L were done. Biogas yield increased with the dose of the cattle feed supplement up to 894 L/kg VS, which was 65% higher than in the control reactor. Similarly, the cumulative biogas production rate (CBPR) increased with successive increase in the dose of feed supplement. Supplementation enabled efficient volatile fatty acids (VFA) elimination and pH increasing; however, the best VFA/TA ratio was achieved with feed supplementation of 25 mg/g of feedstock, providing the highest rate of biogas production (k = 0.22/d). The highest increase in biogas production of 8.0 mL/mg was achieved with the lowest nutrient supplement dosage. Based on these results, it can be recommended that a supply of feed supplement at a ratio of 0.5% of the fresh mass provide considerably increasing biogas production.
