“…The most common PBDs in China are plastic soft digesters (PSDs) and composite material digesters (CMDs). PSDs are also known as bag digesters (BDs) worldwide and include the plastic tubular digester used in Latin America [85,86]. BDs are the most popular PBDs; they have been widely applied successfully because of their low cost and easy implementation and handling.…”

Anaerobic digestion is one of the most sustainable and promising technologies for the management of organic residues. China plays an important role in the world's biogas industry and has accumulated rich and valuable experience, both positive and negative. The country has established relatively complete laws, policies and a subsidy system; its world-renowned standard system guarantees the implementation of biogas projects. Its prefabricated biogas industry has been developed, and several biogas-linked agricultural models have been disseminated. Nonetheless, the subsidy system in China's biogas industry is inflexible and cannot lead to marketization, unlike that of its European counterpart. Moreover, the equipment and technology levels of China's biogas industry are still lagging and underdeveloped. Mono-digestion, rather than co-digestion, dominates the biogas industry. In addition, biogas upgrading technology is immature, and digestate lacks planning and management. China's government subsidy is reconsidered in this work, resulting in the recommendation that subsidy should be based on products (i.e., output-oriented) instead of only input subsidy for construction. The policy could focus on the revival of abandoned biogas plants as well.Sustainability 2020, 12, 1490 2 of 21 effectively and widely implemented in countries where governments and institutions are involved in the subsidy, planning, design, construction, operation, and maintenance of biogas plants [7,8]. A number of countries in Asia and Africa have launched massive campaigns to popularize biogas technology via government support and international aid (Table 1) [9,10]. Globally, it is estimated that 50 million micro-digesters (family size), 132,000 biogas engineering projects (about 15,000 in Europe [11]) and 700 biogas upgrading plants are operating [12]. Promotion of biogas technology has several opportunities and obstacles. Numerous studies have focused on these aspects to discuss the country scenario. Many case and field studies have aimed to assess biogas technology to verify its multiple benefits [13,14] and identify potential barriers [8,[15][16][17][18][19][20][21]. However, these studies are limited to individual country scenarios. The progress and prospect of the biogas industry in different nations vary widely. Nearly no crosswise comparisons have been made for different countries. The current study intends to fill this gap.China leads the world in domestic biogas technology. With the expansion of the biogas industry, lessons learned, whether positive or negative, would be valuable and abundant for countries whose biogas industry is still at the initial stage, including nations mainly in South and Southeast Asia, Africa, and Latin America. Meanwhile, along with the development of medium-and large-scale biogas plants (MLBPs), progress is not trouble-free [22]. (According to the Chinese biogas standard NY/T 667-2011 Classification of Scale for Biogas Engineering, the thresholds of medium-scale and large-scale biogas plant are 300 m 3 and 500 m...

“…Existen tres tipos de biodigestores de bajo costo, que son los más comunes en las zonas rurales de Latinoamérica y en países en desarrollo. Estos biodigestores son los de domo fijo, de tambor flotante y tubulares plásticos [31], [32], que operan con estiércol animal y residuos de cosecha. Su volumen puede variar entre 5 y 20 m³ y proveen aproximadamente 0,5 m 3 de biogás por cada 1 m³ de biodigestor.…”

“…En comunidades rurales de escasos recursos y con problemas de accesibilidad, los biodigestores tubulares de plástico son la alternativa más económica. Los costos por materiales de un biodigestor tubular de plástico pueden estar dentro del rango de los 220-280 USD [33], mientras que los de polietileno de alta calidad, PVC o geomembrana podrían costar entre 500 y 700 USD y los de domo fijo o tambor flotante podrían costar entre 700 y 1.200 USD [31]. En la producción de calor para la cocción de alimentos, el biogás tiene un costo específico de 0,17 USD/persona/día, el más bajo frente a otras fuentes como la biomasa sólida (leña) con un costo de 0,5 USD/persona/día, el gas (LPG) de 0,43 USD/persona/día y la electricidad con un costo de 1,03 USD/persona/día [43].…”

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.

“…Moreover, the VS/TS ratio is encountered in the range between 0.52 and 0.98 that specify the high organic matter content easily biodegradable. The C/N ratio is considered as optimal between 15 and 45 (Garfí et al, 2016). It can be observed that CW has a lower C/N ratio; as a consequence the co-digestion of CW with FDM could enhance the nutritional equilibrium in the substrate composition.…”

The aim of this study was to analyze the behavior and the stabilization of Cheese Whey (CW) anaerobic digestion in a plug flow reactor by means of the effluent recirculation use and the implementation of the Anaerobic Co-Digestion (ACOD) system with Fresh Dairy Manure (FDM). These alternatives were proposed to avoid the potential acidification. For the monodigestion, it was proved that the system cannot support high OLR. The ACOD of CW with FDM presented a benefic alternative because it implemented a balanced medium due to each substrate contribution. The efficiency stability of the process was guaranteed by the buffer capacity, which was kept around 0.4. The ACOD process allowed maintaining process stabilization, and the biogas production surged when recirculation began. The best performance of the system was reached with 2g VS/L*day with recirculation, obtaining a biogas production of 469.2 L/kg*day and a degradation of the 81% in volatile solid basis from the input organic matter.
