“…The unsuited dispose (such as burn) of corn straw not only wastes of resource but also leads to environmental problems. Anaerobic digestion (AD) has been widely employed as an efficient means of treating organic wastes (Jang et al, 2013), which is an ideal way for comprehensive utilization of corn straw. Generally, hydrolysis is regarded as the rate-limiting step in AD of cellulosic substrate such as corn straw.…”

Due to rapid urbanization, the quantity of wastewater treatment plants (WWTP) has increased, and with it the amount of waste generated by them. Sustainable management of this waste can lead to the creation of energy-rich biogas through the fermentation process. This review presents recent advances in the anaerobic digestion process resulting in greater biogas production. Disintegration techniques for enhancing waste activated sludge fermentation can be generally partitioned into biological, physical and chemical, each of which are covered in this review. These disintegration techniques were compared mainly in terms of their biogas yield. It was found that ultrasonic and microwave disintegration provides the highest biogas yield (>500%); however, they are also the most energy demanding (>10,000 kJ kg-1 total solids).

“…Through anaerobic digestion, a consortia of different types of microorganisms interact closely to promote the transformation of complex organic compounds into simple ones (Jang, Park, Ha, & Park, ; Peng, Song, Wang, Yuan, & Liu, ). The actions of these microorganisms occur simultaneously, and the metabolic products generated by a group acts as the substrate to the other group.…”

This study evaluated, at a laboratory scale, samples composed of wastewater treatment sludge, blood, and swine manure, which were subjected to the process of anaerobic co-digestion. The goal of the study is to identify the reduction of organic loads through the removal of available carbon and its conversion to biogas. The results showed variation in hydraulic retention time, and that the total average volumes of biogas generated in 1-liter (L) reactors filled with 600 milliliters (ml) of samples, ranged from 3.37 to 18.76 L, with percentages of methane ranging between 57.9% and 71.1%. The largest volumes of biogas resulted from blends with lower percentages of swine manure, where the initial amounts of carbon in milligrams per liter (mg/L) were larger within the samples. All of the blends submitted to anaerobic treatment showed reductions in carbon content, and consequently, in chemical and biochemical oxygen demand, demonstrating that the efficiency of biodigesters in the treatment of waste is variable and related to physical-chemical factors, such as the amount of carbon available.
