“…To determine whether social conditions are suitable for biogas plant project implementation, the following information should be considered: (1) whether the location is rural or urban [24]; (2) social needs (heat, electricity, and digestate) and concerns (odor, waste disposal problems, etc.) [25,55,77,78,108]; and (3) ethical barriers and socio-cultural taboos (e.g., the use of human waste as soil conditioner) [8,18,30,34,72]. Determining whether a location is rural or urban is important in estimating the appropriate scale and technologies for a project.…”

“…The sustainability of a biogas plant project can be compromised when there is no supporting system running in the background. In the emerging Asian region, a biogas plant project may be sensitive to the following institutional issues: (1) MSW laws and enforcement [49,60,77,93], (2) financial support mechanisms (green tariffs, funding, subsidies, tax waving, fertilizer control systems and pricing) [22,24,25,28,69,93,94], (3) stable administrative organizations and technical support [72][73][74][75], and (4) construction site availability [31,35,72]. These aspects shape the sustainability of biogas plants in various ways.…”

Due to its ability to recover both material and energy from organic waste, biogas technology is considered the best technology for treating organic waste. While in many emerging Asian countries more than 50% of municipal waste is organic waste, the amount of organic waste treated with biogas technology remains very limited. This study identified key challenges faced by practitioners in sustaining biogas plants from literature and interviewed a number of sustainably operating biogas plant managers and, based on the findings, developed an implementation framework to help decision makers and practitioners in planning a sustainable municipal organic waste biogas plant facility.

“…Adicionalmente, si se consideran las condiciones de transporte por carreteras inadecuadas, temporadas de lluvia, largas distancias, altos niveles de pobreza y la continua migración de la mano de obra rural a la ciudad, los costos globales de estos biodigestores no son adecuados para productores de bajos recursos [33]. El tiempo de vida de un biodigestor de domo fijo puede estar entre 15 y 20 años; mientras que un biodigestor de tambor flotante puede tener un tiempo de vida de entre 12 y 15 años, debido a la corrosión [34]. Ambos biodigestores no requieren sistemas de mezclado y operan sin control de temperatura.…”

ResumenEl biogás producido por la digestión anaerobia de residuos pecuarios es una solución para la sustitución de la biomasa tradicional usada en iluminación y calor. Su uso presenta ventajas como la mejora en la productividad de las fincas, la reducción del impacto ambiental y el rompimiento de la dependencia a los combustibles fósiles y agroquímicos. Sin embargo, aún se tiene poca difusión en las zonas rurales de Colombia, principalmente por el desconocimiento de las potencialidades y los beneficios. Por tal motivo, la presente revisión propone brindar una perspectiva de la digestión anaerobia desde los aspectos técnicos más relevantes, la importancia del sustrato y los tipos de biodigestores de bajo costo más comunes. Se concluye que es necesario mejorar las técnicas para hacerlas más asequibles y planear programas de financiación que permitan la expansión plena de la tecnología a pequeña y mediana escala. Palabras clave: biogás; digestato; digestión anaerobia. AbstractThe biogas produced by the anaerobic digestion of livestock waste is a solution for the replacement of traditional biomass used in lighting and heat. Its use offers advantages such as: the improvement in the productivity of the farms, reduction of the environmental impact and breaking the dependence on fossil fuels and agrochemicals. However, there is still little diffusion of it in rural areas of Colombia, mainly due to ignorance of its potential and benefits. For this reason, this review provides a perspective of anaerobic digestion from the most relevant technical aspects, the importance of the substrate and the most common types of low-cost biodigesters. It is concluded that it is necessary to improve the techniques to make them more affordable and to plan financing programs that allow the full expansion of this technology to small and medium scale.

Countries with a large agricultural sector have enormous potential for energy production using biogas technology. This paper analyses the situation in Pakistan as a representative example. Although many biogas plants were installed, only very slow growth in the biogas sector can be observed. Since the last three decades the country is facing a severe energy shortfall. To overcome this challenge, energy from organic waste is one of the best possible solution. This study reviews the key technical challenges associated with the operation and sustainability of biogas plants. The problems in basic infrastructure such as leakages due to gas pressure, inadequate removal of digestate, no mechanism for scum avoidance, and steel corrosion were identified, and solutions were proposed. Moreover, organizational structures for renewable energy, critical flaws in plant design, operational challenges, and updated technology aspects to attain maximum and sustainable growth in biogas sector are discussed, which could help the countries in the region to enhance their biogas production.
