The global biofuel production was increased by 21.9% in 2019 as compared with 2015 (Statista, 2020a). The major biofuel producing countries in 2019 were the United States, Brazil, Indonesia, Germany, France, and China with the production of 1557.1, 992.2, 275.5, 143.4, 113, and 111.3 PJ, respectively (Statista, 2020b). This chapter describes ...

Dec 30, 2021 · Biofuel generation plays a crucial role in the water-food-energy nexus for sustainable development. These biofuels utilise ecological resources and services and have a significant role in the various nexus [61]. Biofuel promotion develops a complete linkage between food, water, land, and energy [62].

Mar 18, 2021 · To mitigate GHG emissions while meeting the global fuel demand, biofuel technology advancements need to focus on (1) optimization of current biofuel-production technology for higher productivity and efficiency of lignocellulosic biomass conversion, (2) diversification of feedstocks to ensure the viability of biofuel production within existing …

Global biofuel production has been increasing steadily over the last decade – production rose from 16 billion liters in 2000 to more than 100 billion liters in 2011, and today biofuel provides approximately 3% of road transport fuel globally (on an energy basis) (International Energy Agency, 2013). The transportation sector is a major ...

Feb 22, 2012 · In the United States which is the largest biofuel producer in the world, biofuels generated 4 % of the energy used for transportation in 2011. In 2009, in Brazil, which is the second largest biofuel producer in the world, a total of 23 % of the energy for road transportation came from biofuels. Large-scale biofuel production in the world can ...

Dec 1, 2023 · One of the key challenges in biofuel production is the high cost of pretreatment, which needs to be reduced to achieve at least a carbon–neutral product for practical applications. The present review concludes newer generations of biofuels should be introduced by exploring co-culturing, nanotechnology, and genetic modification.

May 1, 2024 · Biofuel production also entails significant impacts on water resources and biodiversity. The cultivation of crops for biofuels can be highly water-intensive. Crops such as sugarcane and corn, often used for biofuel production, require large quantities of water, which can exacerbate water stress in already vulnerable areas [ 23 , 34 ].

May 15, 2006 · Biofuel cells use enzymes as catalysts (alone or within an organism) and tend operate under mild conditions (20–40 °C, near-neutral pH). These properties make biofuel cells an attractive development prospect for use in applications where generating high temperatures is difficult, or where harsh reaction conditions are undesirable.

Jun 15, 2023 · Some studies focus on concepts of biofuel economy directly related to sustainable development goals (SDGs). For example, the use of biofuels offers new opportunities for poverty alleviation and economic growth for agriculture-based economies in low-income countries (Costa and Oliveira, 2022; Prasad and Ingle, 2019; Vera et al., 2

Feb 1, 2022 · Regarding biofuel production processes, four types are studied: (i) fermentation of sugars (i.e., glucids) and (ii) biomass gasification to produce ethanol, (iii) transesterification of lipids (i.e., triglycerides) to produce FAME (fatty acid methyl esters), and (iv) hydrotreating of lipids (i.e., triglycerides) to produce hydrotreated ...
