Table 1. Production costs of different biofuels (US$/liter) 1 . Environmental sustainability of sugarcane ethanol in Brazil Costs item United States Brazil EU Maize wet milling Maize dry milling Sugarcane Sugar beets �e long track record of Brazilian sugarcane ethanol proved its economic sustainability over time, while improving its social and environmental indicators, involving technology transfer from Europe, US and other regions and developing several innovations at national level. �is program no longer exists, however it has contributed signi�cantly to improve the productivity of sugarcane and ethanol extraction rates (Figure 2). Due to the increasing internal demands and the possibility of future exports, it is expected that the Brazilian production might increase to 47 billion liters of ethanol by 2015, with an estimated annual growth rate of 10-13% (Table 2). Several steps will be necessary to achieve these production targets, including sustainable planning of the sugarcane expansion into new areas, improving the logistics, the development of global markets and continuously developing new technological innovations, while at the same time improving the environmental performance of existing brown �elds (areas with already established sugarcane �elds and industry either/or sugar mills/distilleries) and especially from new green �elds (new areas for expansion of sugarcane �elds and new industrial plants), which are being implemented using cutting edge technologies in the agriculture and in the industry. With more than 360 mills in operation, there is a gap between the best practices available and the average performance of Brazilian mills, however due to recent developments in the ethanol business, with the consolidation of economic groups, capacity building programs, companies going public, new investments Sugarcane ethanol 115 Molasses 3 Raw sugar 3 Refined sugar 3 Feedstock 2 0.11 0.14 0.40 0.43 0.25 0.84 0.97 0.08 0.26 Processing 0.17 0.14 0.25 0.21 0.10 0.10 0.10 0.14 0.52 Total 0.28 0.28 0.65 0.63 0.34 0.94 1.07 0.22 0.78 Source: USDA (2007). 1 Excludes capital costs. 2 Feedstock costs for US maize wet and dry milling are net feedstock costs; feedstock costs for US sugarcane and sugar beets are gross feedstock costs. 3 Excludes transportation costs. 4 Average of published estimates.
