“…China has also emerged as a major producer of bioethanol, preferentially from sugar cane, cassava and yams (Cascone 2007), and so has the European Union, producing bioethanol from wheat and sugar beet (Berndes and Hansson 2007). India, Russia, Southern Africa, Thailand and the Caribbean are emerging as important producers of ethanol as a transport fuel (Cascone 2007;Szklo et al 2007;Barrett 2007;Amigun et al 2008;Nguyen et al 2008). Estimated bioethanol production volumes for 2006 in the main production areas are given in (Licht 2006;Antoni et al 2007;Szklo 2007;Sanchez and Cardona 2008) the USA approximately 12% (Canakci and Sanli 2008).…”
