Analysis of the supply chain of liquid biofuels -2016

2016

Abstract

Due to political, economic, environmental and energy security reasons as well as climate change mitigation, the United States, Brazil and the European Union have promoted the substitution of fossil fuels for fuels derived from biomass, called biofuels.

Biofuels can be classied into three generations, depending on the origin of the biomass used for their production. First generation biofuels (1G) are those obtained from food crops such as sugarcane, corn, and vegetable oils. Second generation (2G) are obtained from waste not used for food, such as agricultural and forest residues, plant oil or animal fat among others; crops from marginal land are also considered second generation fuels because they do not compete with food production. Third generation biofuels (3G) are fast-growing non-food plants with high energy content (energy crops) in addition to having minimum supply of agricultural input, such as specialized algae, switchgrass or perennial grass.
