“…Yang et al used FeS/sulfite-pretreated sludge for AD; they found that, with propionic acid and butyric acid as substrates, the presence of sulfate and iron ions can increase the degradation rates of propionic acid and butyric acid by 23.4% and 8.9%, respectively [50]. Previous studies have shown that iron ions can promote the conversion of propionic acid into acetic acid [52]. This shows that applying the PrS of Solar/Fe (II)/PS-pretreated RS to AD can promote the conversion of propionic acid into acetic acid during AD, which is undoubtedly beneficial to improving the energy conversion efficiency of AD.…”

Rice straw (RS) is among the agricultural waste products with the highest methane production potential in the world, but the refractory complex structure and high carbon-to-nitrogen ratio of RS cause low methane conversion efficiency and limit its widespread application in anaerobic digestion. In this study, Solar/Fe (II)/persulfate (PS) pretreatment of RS was investigated to improve microbial accessibility, and anaerobic co-digestion combined pretreated RS and swine wastewater (SW) were evaluated to improve the efficiency of anaerobic digestion. The results showed that the Solar/Fe (II)/PS pretreatment could disrupt the structure of RS and promote the reduction of sugar content, increasing microbial accessibility to RS. When all the components of the pretreated RS (including the use of the solution remaining from the pretreatment) were anaerobically co-digested with SW, the cumulative biogas production and cumulative methane production reached 252.10 mL/g·VS and 163.71 mL/g·VS, 19.18% and 36.97% higher than the anaerobic co-digestion of untreated RS and SW, respectively. The anaerobic co-digestion of the Solar/Fe (II)/PS-pretreated RS with SW is a promising approach to achieving the utilization of RS components and maximizing methane yields, providing a cost-effective and pollution-free method for the production of high-quality bioenergy from agricultural waste.

“…Currently, FW management is performed through landfill, fertilizer generation, composting, incineration, and anaerobic digestion [4,6]. Anaerobic digestion, a biochemical process that converts organic matter into renewable bioenergy (methane and hydrogen), is the most straightforward and feasible technology for FW disposal [7,8]. Volatile fatty acid (VFA) inhibition, rapid acidification, and low essential trace elements (Fe, Ni, Co, and Mo) set up a barrier for biogas generation from mono-digestion of FW [8,9].…”

Volatile fatty acid (VFA) inhibition, rapid acidification, and low essential trace elements (Fe, Ni, Co, and Mo) set up a barrier for biogas generation from mono-digestion of FW [8,9]. To tackle this challenge, anaerobic co-digestion of FW with other substrates such as sludge [10], garden waste [11], paper waste [12], and animal ma-nure [12] have been extensively investigated.…”

“…MA production does not require fresh water resources or arable land and, therefore, has low levels of competition with the food market compared to other solid substrates [17]; however, mono-digestion of MA is hindered by low C/N ratios and cell wall degradability [18]. To address these obstacles, several studies have evaluated the feasibility of coupling MA with a variety of complex organic substrates, including diatomite [8], agri-industrial waste [19], and lipid waste [20]. Anaerobic co-digestion of MA could simultaneously enhance biogas production and microcystin biodegradation [21].…”

There is an urgent need for clean recycling strategies to address the increase in food waste (FW) and the harvesting of microalgae (MA). In this study, biogas production potential and operational stability were evaluated by testing combinations of FW and MA mixed at five different ratios. Co-digestion of FW and MA improved substrate biodegradability, achieving a decomposition rate of 0.45/d (FW/MA = 1:1), which is 1.25 to 1.55 times higher than that of MA or FW alone. Co-digestion of FW and MA resulted in a synergistic effect, improving biogas yield by 2.04–26.86%. Four mathematical models were applied to estimate biological degradation and biogas production kinetics, and the Cone model performed better than the other models in terms of reliability and accuracy. The abundance of Bacteroidetes, Firmicutes, and Synergistetes peaked at FW/MA = 1:1. At the same ratio, the genera Methanospirillum, Methanocorpusculum, and Methanomethylovorans were also found to have increased in abundance. The optimal ratio was found to be 1:1 for co-digestion of FW and MA, which is a feasible approach for simultaneous bioenergy production and biomass waste co-disposal.
