“…On the contrary, the better performance of a two-stage system compared with a singlestage one was previously reported in the literature [33]. For example, Nielsen et al [34] tested a lab-scale system in order to compare the operation of a two-stage and a conventional single-stage system for the treatment of cow manure.…”

The growing interest in processes that involve biomass conversion to renewable energy, such as anaerobic digestion, has stimulated research in this field in order to assess the optimum conditions for biogas production from abundant feedstocks, like agro-industrial wastes. Anaerobic digestion is an attractive process for the decomposition of organic wastes via a complex microbial consortium and subsequent conversion of metabolic intermediates to hydrogen and methane. The present study focused on the exploitation of liquid cow manure (LCM) and cheese whey (CW) as noneasily and easily biodegradable sources, respectively, using continuous stirred-tank reactors for biogas production, and a comparison was presented between single- and two-stage anaerobic digestion systems. No significant differences were found concerning LCM treatment, in a two-stage system compared to a single one, concluding that LCM can be treated by implementing a single-stage process, as a recalcitrant substrate, with the greatest methane production rate of 0.67 L CH4/(LR·d) at an HRT of 16 d. On the other hand, using the easily biodegradable CW as a monosubstrate, the two-stage process was considered a better treatment system compared to a single one. During the single-stage process, operational problems were observed due to the limited buffering capacity of CW. However, the two-stage anaerobic digestion of CW produced a stable methane production rate of 0.68 L CH4/(LR·d) or 13.7 L CH4/Lfeed, while the total COD was removed by 76%.

“…The soil crop yields increased in a sustainable manner over the time can reduce the need for chemical fertilizers requirement. Hence, the effects and damages of chemical fertilizers on the environment will be minimized by decreasing the usage of them (Nasir et al., 2014; Werle and Dudziak, 2014). In addition to removal of carbon-containing compounds, pesticide-based hazardous and carcinogenic wastes are the chlorinated organic compounds (chlorophenols, chloromethane, cresol, PCBs, etc.)…”

Bioenergy is an effective energy form used by developing countries. It covers about 38% of the energy consumed primarily obtained from the biomass in about 13% of the world. Due to the energy production costs, much attention has currently been paid on alternative bioenergy sources in the developing countries. Biofuels may be used instead of fossil fuels to produce power, heat, and/or some chemicals. Its production with local resources suggests a reproducible alternative streamlining the economic and social improvement in developing countries, in case the bioenergy projects are established economically viable and well planned with local cooperation. Biofuels are important resources which can take place with fossil-based fuels. Generally speaking, biofuels offer several benefits such as the reduction of greenhouse gas emissions, regional social and structural development, sustainability in energy provision, and agricultural development. In this study, a life cycle analysis of a full-scale biogas plant was conducted. In the life cycle analysis, the ecological effects of the biogas process, the by-products from the biogas production, and the cogeneration unit where the electricity generation is performed are evaluated quantitatively according to the ISO 14040. The functional unit of the plant was designed for 30 tons per day big cattle manure, 5 tons per day poultry manure, and 15 tons per day cheese whey of industrial biogas plant.

“…Biogas is derived from the anaerobic digestion of organic matter such as manure, municipal solid waste, sewage sludge, biodegradable waste and agricultural slurry under anaerobic conditions (Appels et al 2008;Nasir et al 2014). Anaerobic digestion process is used to convert biomass into biogas with the help of microorganism (Bharathiraja et al 2014a, b).…”
