“…The use of biogas to replace nonrenewable fuels may especially benefit rural populations that suffer most from a lack of electricity, due to socioeconomic and environmental issues. In this sense, countries like India (Singh et al., 2020; Usmani, 2020), Venezuela (López‐gonzález et al., 2019; Pietrosemoli & Rodríguez‐Monroy, 2019), Myanmar (Pode et al., 2016; Sovacool, 2013), Afghanistan (Ahmadzai & Mckinna, 2018; Rostami et al., 2017), and Azerbaijan (Vidadili et al., 2017) could benefit from using the studied process. Research evaluating low‐cost reactor configurations or the use of rural biodigesters for the anaerobic degradation of the presently studied wastes could contribute to the dissemination of the process in these countries.…”

Lipids are attractive substrates for anaerobic digestion due to their high methane production yield. However, high concentrations of lipids may cause problems in anaerobic processes. Typically, grease trap waste is mechanically removed and discharged, both generating environmental issues and wasting a potential energy source. In this study, grease trap waste from a dairy wastewater treatment plant was subjected to anaerobic digestion. Untreated and pretreated sugarcane bagasse was evaluated as fat adsorbents to reduce the inhibitory effect of the fatty waste. The bagasse pretreated by the organosolv method was the condition that most contributed to increased methane production (82%) from anaerobic digestion of dairy fatty waste at 0.5 g COD.g–1TVS concentration. Untreated bagasse provided the second‐best condition, followed by hydrothermally treated bagasse, presenting no statistical difference. The obtained results showed the potential of using sugarcane bagasse as a strategy to reduce the inhibitory effect of the fatty waste from the dairy grease trap, making this waste another possible source for generating biogas.

“…The United States, for example, plans to replace 30% of liquid oil with biofuels in 2025 [6]. India increased biofuel rates from 5% to 20% [9]. India plans to reduce its dependency on oil by 10% in 2022 [10].…”

Biofuels are receiving increased scientific attention, and recently different biofuels have been proposed for spark ignition engines. This paper presents the state of art of using biofuels in spark ignition engines (SIE). Different biofuels, mainly ethanol, methanol, i-butanol-n-butanol, and acetone, are blended together in single dual issues and evaluated as renewables for SIE. The biofuels were compared with each other as well as with the fossil fuel in SIE. Future biofuels for SIE are highlighted. A proposed method to reduce automobile emissions and reformulate the emissions into new fuels is presented and discussed. The benefits and weaknesses of using biofuels in SIE are summarized. The study established that ethanol has several benefits as a biofuel for SIE; it enhanced engine performance and decreased pollutant emissions significantly; however, ethanol showed some drawbacks, which cause problems in cold starting conditions and, additionally, the engine may suffer from a vapor lock situation. Methanol also showed improvements in engine emissions/performance similarly to ethanol, but it is poisonous biofuel and it has some sort of incompatibility with engine materials/systems; its being miscible with water is another disadvantage. The lowest engine performance was displayed by n-butanol and i-butanol biofuels, and they also showed the greatest amount of unburned hydrocarbons (UHC) and CO emissions, but the lowest greenhouse effect. Ethanol and methanol introduced the highest engine performance, but they also showed the greatest CO2 emissions. Acetone introduced a moderate engine performance and the best/lowest CO and UHC emissions. Single biofuel blends are also compared with dual ones, and the results showed the benefits of the dual ones. The study concluded that the next generation of biofuels is expected to be dual blended biofuels. Different dual biofuel blends are also compared with each other, and the results showed that the ethanol–methanol (EM) biofuel is superior in comparison with n-butanol–i-butanol (niB) and i-butanol–ethanol (iBE).

“…A considerable amount of academic research focuses on the role of agriculture and forestry in sustainable development and investigates important energy-related issues. For example, Arabatzis and Malesios (2013), Deen (2017), Kolovos et al (2011), Kyriakopoulos et al (2010aKyriakopoulos et al ( , 2010b, Procentese et al (2019) and Usmani (2020) investigate biofuel potential-related issues in forestry or agriculture and challenges of the switch to renewable energy, while Dauber and Miyake (2016) focus on strategies that show the nexus between food, energy crops and biodiversity issues. The sustainability assessment of other economic sectors is also important due to the recent initiatives on combating the climate change and improving resilience (Turturean et al, 2019).…”

Over the recent decades, the evolution of the European Union (EU) agricultural system has resulted in significant structural changes in member states. Knowledge about the nature and main patterns of structural change is critical to select a sustainable development path for the EU agriculture. This paper contributes to the academic discourse on structural changes in agriculture demonstrating the nexus between socioeconomic and environmental aspects of development. In this regard, results are important to understand the contribution of the EU agriculture to climate change, because study deals with energy use and greenhouse gas emissions. The research covers period from 2008 to 2018 and investigates the fundamental structural change measures, namely, gross value added, labour and agriculture-related energy emissions, in EU member states. Structural changes are investigated applying a shift-share analysis that allows calculating a performance of individual member states, compared to the EU economy. The applied shift-share model investigates the situation of individual member states employing three components. The first component tracks the development of the selected measures with the EU economy growth, the second component shows the change due to effect of economic activities and the third shows competitiveness of agriculture in member states. The shift-share analysis empowers ranking member states in accordance with their progress towards the sustainable development. Findings suggest that EU economy faces the outflow of labour from agriculture and this trend is common for most countries. The changes of gross value added and emissions for fuel combustion demonstrate both upward and downward trends. However, research results suggest that new member states often face more fundamental changes.
