“…Arthur et al reported that the biogas generated from the biowaste produced by persons is 0.03 m 3 per day for sewage sludge. The pilot study conducted in a similar institution shows that the biogas generated from the waste per person is between 0.014 and 0.019 m 3 .…”

The scarcity of conventional energy sources and their environmental impacts have led to successful implementation of biogas technologies in various applications. However, the lack of awareness in the society and economic viability are a few constraints that hinder the effective use of biogas in many sectors. Therefore, intensive research is needed to overcome the above said issues and extend the use of biogas into many newer avenues. Academic institutions are the places where people have more awareness on the environmental impacts. However, the nonuniform availability of biowastes and the lack of studies on the economic benefits of this technology restrict the implementation of the same. This study focuses on the economic benefits of implementing three types of biogas digesters, KVIC, JANATA, and Fiber‐glass reinforced polyester biogas plants, in five different academic institutions where the student population and generation of biowastes throughout a year are nonuniform, and the digester may not run with full load continuously. Based on a pilot study, the quality and quantity variations because of the nonuniform strength of student during a year have been studied and the same have been used to predict the biogas generation in the selected institutions. The result shows that biogas energy production is economically viable for capacities ranging from 25 to 450 m3 with a payback period between 3.18 and 7.59 years for various types used in the study. The economic viability of the biogas plants is proved with positive net present value. © 2018 American Institute of Chemical Engineers Environ Prog, 37: 1901–1907, 2018

“…The results of this study was of particular interest because, domestic biogas digesters predominantly used in developing countries are highly efficient for livestock manure (Tauseef et al, 2013), although they could also be used for other substrates as well; however, in those cases, they are not that efficient (Abbasi & Abbasi, 2010). Some of the common biogas digester designs mostly used in developing countries include floating drum (KVIC, IARI, ASTRA, Botwana, Jwala models), fixed dome (Chinese Puxin, Janata and Deebandhu models), hybrid and balloon digester (Arthur, Baidoo, Antwi et al, 2011;Arthur, Baidoo, Brew-Hammond et al, 2011;Tauseef et al, 2013). A survey conducted indicated that about 80% of the biogas digester designs in Ghana are based on the fixed dome design (Arthur, Baidoo, Brew-Hammond et al, 2011;Bensah, 2010).…”

Based on the historic livestock and poultry production data between 2007 and 2017 (Table 2), the methane production projections for 2020 and 3030 were calculated and have been presented in Table 8.…”

“…This is because the ideal pH for the microbes utilized during the hydrolysis stage is 5-7 and methanogens are most efficient at a pH of 7-8. The temperature should also be between 32-35 °C (Arthur, 2011). These are important for promoting bacterial growth since the microbes are very sensitive to physical conditions.…”

Developing countries throughout the world currently fuel kitchen stoves for cooking by burning wood which is responsible for many health and environmental problems. Producing fuel for cooking via anaerobic digestion is a very ecofriendly and resourceful solution that is being explored. To determine the sustainability of anaerobic digestion throughout these regions, multiple biodigester designs were tested under conditions specific to various third-world countries; the countries tested were Nicaragua, Bolivia, Nigeria, India and Indonesia. Factors to be considered included the use of local biomass resources and building materials. Determining the fueling efficiency of anaerobic digestion in comparison to burning wood consisted of evaluating the production costs and environmental impacts. This was accomplished utilizing technoeconomic analysis (TEA) and life cycle assessment (LCA). TEA results indicated that tube digesters are the most cost effective method of anaerobic digestion in all countries tested; tube digestion at a family scale ranged from approximately $0.24 per meal to $0.73 per meal. The LCA showed that operation of anaerobic digestion required much more water than previously considered which may cause it to not be a sustainable method. However, it did emit a much lower amount of carbon dioxide than burning wood. The CO 2 emissions per meal ranged from 0.97 kg per meal to 1.29 kg per meal. The water impacts ranged from 76 L/ meal to 100 L/meal. Comparing the two fueling methods proved that anaerobic digestion was a more economically and environmentally effective process. Abstract.
