“…There are other techniques for manure treatment such as anaerobic digestion (AD), biological treatment, incineration, pyrolysis, and gasification [14,[17][18][19], which are not as commonly used because of their costs, time investment required, and/or ineffectiveness [20]. For instance, AD presents numerous advantages such as pollution reduction (when considering GHG emissions and nutrient leachates), production of valuable byproducts such as fertilizers, and the production of renewable energy.…”

Evaluation of Biogas Potential from Livestock Manures and Multicriteria Site Selection for Centralized Anaerobic Digester Systems: The Case of Jalisco, México

et al. 2020

The state of Jalisco is the largest livestock producer in Mexico, leading in the production of swine, eggs, and milk. This immense production generates enormous amounts of waste as a byproduct of the process itself. The poor management of livestock-derived waste can lead to multiple environmental problems like nutrient accumulation in soil, water eutrophication, and air pollution. The aim of this work is to establish a replicable geographic information system (GIS)-based methodology for selecting priority sites in which to implement anaerobic digestion units. These units will use multiple parameters that evaluate environmental risks and viability factors for the units themselves. A weighted overlay analysis was used to identify critical regions and, based on the results, clusters of individual livestock production units (LPUs) across the state were selected. Nitrogen and phosphorus recovery, as well as the energetic potential of the selected clusters, were calculated. Four clusters located mainly in the Los Altos region of Jalisco were selected as critical and analyzed. The results indicate that Jalisco has the potential to generate 5.5% of its total electricity demand if the entirety of its livestock waste is treated and utilized in centralized anaerobic digestion units. Additionally, 49.2 and 31.2 Gg of nitrogen and phosphorus respectively could be valorized, and there would be an estimated total reduction of 3012.6 Gg of carbon dioxide equivalent (CO2eq).

“…The success of a biogas power plant lies in its economic viability. Currently, the sale of electricity could contribute the profitability in a large part [54]. However, only a few biogas plants can be connected to the grid due to the hinder of monopoly enterprises.…”

What Could China Give to and Take from Other Countries in Terms of the Development of the Biogas Industry?

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...

“…For example, Mexico City hosts the second largest wholesale market in the world [ 3 ], where 13,073 tons of municipal solid waste (MSW) are generated daily, of which about 18% is not collected and is disposed of in illegal dumps, burning in the open air or handled by an informal waste sector [ 4 ]. The municipal solid waste management system of the city consists of 12 transfer stations, 3 separation and 8 composting plants, and 5 landfills located outside of the city [ 5 ].…”

“…There are some publications describing the experience of the anaerobic digestion process at pilot and industrial scale [ 16 – 18 ]. There are authors like Tsydenova [ 5 ], who have carried out studies on anaerobic digestion in Mexico. They conclude a possible economically viable option and a favorable environmental impact due to the reduction of methane released into the atmosphere.…”

This paper presents the analysis of a pilot anaerobic digestion plant that operates with organic fraction of municipal solid waste (OFMSW) from a wholesale market and can treat up to 500 kg d−1. The process was monitored for a period of 524 days during which the residue was characterized and the biogas production and methane content were recorded. The organic load rate (OLR) of volatile solids (VS) was 0.89 kg m−3 d−1 and the Hydraulic Retention Time (HRT) was 25 d during the process. The yield was 82 Nm3 tons OFMSW−1 biogas, equivalent to 586 Nm3 tons CH4 VS−1. The results obtained in the pilot plant were used to carry out a technical–economic evaluation of a plant that treats 50 tons of OFMSW from wholesale markets. A production of 3769 Nm3 d−1 of biogas and 2080 Nm3 d−1 of methane is estimated, generating 35.1 MWh d−1 when converted to electricity.
