Dec 30, 2021 · Biofuel promotion develops a complete linkage between food, water, land, and energy [62]. The first-generation biofuels are derived from agricultural crops and, therefore, can negatively impact the ecosystem, especially inland usage and deforestation [61] , [63] , [64] .

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 ...

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 …

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 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.

Jan 1, 2023 · Biofuel-producing countries heavily rely on domestic feedstock for biofuel production, which is influenced by factors such as climate, region, and market trends. The overall price of biofuels largely depends on the type of biofuel, feedstock, geographical location, resources required, such as land or water, competition with food crops, the ...

Feb 1, 2025 · While biofuel production from seaweed is currently not cost-effective, it could become feasible with reduced production costs and increased cultivation areas. However, large-scale seaweed farming presents potential environmental trade-offs, including habitat disruption, nutrient depletion in local waters, and competition with marine ecosystems.

Apr 1, 2024 · Biofuel's blending program in India has been widely affected by the non-availability of sufficient feedstock to generate biofuel (PIB, 2018). The new Biofuel Policy 2018 addresses this issue and encourages farmers to dispose of their surplus stock economically. This new policy initiative will help in reducing India's crude oil import dependence.

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 ].

Jan 1, 2019 · First-generation biofuel processes are useful but there is a threshold above which they cannot produce enough biofuel without threatening food supplies and biodiversity. Many first-generation biofuels are dependent on subsidies and are not cost-competitive with existing fossil fuels such as oil, and some produce only limited greenhouse gas ...
