“…Su et al (2024) optimized the grate boiler at 130 t/h, increasing its burning rate by 95.5% and emitting CO at 1917 ppm, much less than the 3178 ppm previously reported [48]. Likewise, Archana et al (2024) mentioned in their research that the anaerobic digester technology used to produce biogas is the most promising technique to replace the generation of fuel from fossil sources when the biomethane produced from agricultural or cattle waste is the fuel for public transportation, replacing diesel/gasoline [49]. Patel et al (2024) calculated that 1500 tons/year of agricultural waste can replace the gasoline demand of 2070 kg/year, while decreasing CO 2 production by 41,218.6 tons/year [50].…”

Scientific reports have diversified enormously in the various thematic areas of the scientific world, generating errors and biases in the searches and directing the various investigations. For this reason, this article provides an approach, from the point of view of bibliometric analysis, to reveal the trends of agricultural waste for its potential use as fuel in generating electrical energy. This research has used the programs RStudio, VosViewer, and Excel for the compilation and analysis of data, whose data were extracted from Scopus during the period from 2013 to 15 March 2024, filtering all types of publications that were not original articles and English language. Scientific reports have found that biodigesters are constantly evolving, improving valves, studying and analyzing different types of agricultural waste, and using microorganisms to accelerate the fermentation process of agricultural waste. The terms biogas (330 occurrences), anaerobic digestion (214 occurrences), and agriculture (212 occurrences) were the words with the highest occurrences. At the same time, the author that stood out was Liu Y., who had an H index of 6 and 117 citations in his six articles published in the Scopus database. Moreover, China (1900 citations) was the country with the highest citation numbers, followed by the United States (1060 citations) and India (967 citations). The designs of biogas production increase efficiency and can increase biodigesters’ performance. The research also reveals the different types of development and trends that stood out and emerged in the last decade, such as the authors who have had the most impact on this topic that has recently emerged and the countries that have obtained the most significant number of publications on the topic.

“…Analyzing the logistic systems behind the implementation of different modes of energy, particularly biogas, is of paramount importance in ensuring the successful and sustainable integration of renewable energy sources to our global energy landscape. Biogas, derived from organic waste materials through anaerobic digestion, presents a promising alternative to conventional fossil fuels (see refs ( 6 ) or ( 7 ) for further details on the recent technological breakthroughs in anaerobic digestion of organic biowaste for biogas generation). However, their widespread adoption hinges on addressing intricate logistic challenges.…”

In this paper, we propose a new mathematical optimization approach to make decisions on the optimal design of the complex logistic system required to produce biogas from waste. We provide a novel and flexible decision-aid tool that allows decision makers to optimally determine the locations of different types of plants (pretreatment, anaerobic digestion, and biomethane liquefaction plants) and pipelines involved in the logistic process, according to a given budget, as well as the most efficient distribution of the products (from waste to biomethane) along the supply chain. The method is based on a mathematical optimization model that we further analyze and that, after reducing the number of variables and constraints without affecting the solutions, is able to solve real-size instances in reasonable CPU times. The proposed methodology is designed to be versatile and adaptable to different situations that arise in the transformation of waste to biogas. The results of our computational experiments, both in synthetic and in a case study instance, prove the validity of our proposal in practical applications. Synthetic instances with up to 200 farms and potential locations for pretreatment plants and 100 potential locations for anaerobic digestion and biomethane liquefaction plants were solved, exactly, within <20 min, whereas the larger instances with 500 farms were solved within <2 h. The CPU times required to solve the real-world instance range from 2 min to 6 h, being highly affected by the given budget to install the plants and the percent of biomethane that is required to be injected in the existing gas network.

“…WWTPs can account for up to 30% of the total operational and maintenance budget, which translates In recent years, there has been a shift towards energy-efficient technologies and practices, including the recovery of resources from wastewater and the integration of renewable energy sources to mitigate the environmental and economic impacts of traditional energy consumption patterns in WWT [14,22]. Several WWT facilities in the United States of America (USA) have developed and implemented energy conservation and management plans [14] that involve the adoption of innovative technologies, such as anaerobic digestion for biogas production, thermal hydrolysis, and the integration of renewable energy sources [23]. The aim of these practices is to reduce the environmental footprint of WWT and transform these facilities from energy consumers into energy producers, highlighting a significant shift towards sustainability in the management of water resources [24].…”

This paper explores the significant role of Wastewater Treatment Plants (WWTPs) in achieving environmental sustainability, with a particular focus on enhancing energy efficiency, resource recovery, and water reuse. WWTPs are crucial for removing pollutants and recovering resources from wastewater, thereby protecting public health and biodiversity. However, they are also associated with high operational costs, substantial carbon footprints, and energy-intensive processes. This article delves into various strategies and technologies to overcome these challenges, aiming to transform WWTPs from energy consumers to energy-efficient resource recovery hubs. Techniques such as anaerobic digestion and the use of advanced oxidation processes and microbial fuel cells are investigated for their potential in energy recovery and efficiency enhancement. Success stories from around the globe are highlighted to demonstrate the feasibility of transitioning to energy-positive WWTP operations. The integration of water reuse systems is also discussed, highlighting recent advancements that enable treated wastewater to be repurposed for agricultural, industrial, and potable uses, thereby promoting sustainability and water conservation. This paper emphasizes the importance of integrating cutting-edge energy management practices to minimize environmental impacts, reduce operational costs, and contribute to a more sustainable water sector.
