“…For crop-based ethanol, balances range from less than 2 for maize to around 2-9 for sugar cane (8 to 10 in the case of Brazil, see [35,42,43]). Sugar-cane-based ethanol, as produced in Brazil, depends not only on feedstock productivity, but also on the fact that it is processed using biomass residues from the sugar cane (bagasse) as energy input.…”

“…Apart from the traditional markets (Brazil, EU, and US) this report sees the Asia-Pacific region is showing an immense potential for future growth, including bioethanol and biodiesel, and is projected to grow at an overall annual growth rate of 28.8 percent over this period. There are of course many other scenarios (e.g., [43,[72][73][74] 15 http://www.fas.usda.gov/). The growth of biodiesel, particularly from palm oil, is tricky because of the key role it plays in human diets (see [75]).…”

A key objective of this paper is to provide an assessment of the current and future situation on the "food versus fuel" debate and to contribute to possible alternatives to minimise or avoid future conflict. The debate has centred on three main areas: (i) food versus biofuel production, (ii) their positive and negative effects (i.e., GHG, climate change, and the broader environment), and (iii) a socioeconomic impact. The debate has been controversial because it has largely been driven by politics, ethical/moral considerations, and vested interests rather than by science. The paper focuses on food prices, land competition, GHG, energy balance, and energy subsidies and concerns with the rapid expansion of bioenergy for electricity and heat, climatic changes, the role of agriculture as a key factor, the potential of biomass energy resources, and the various alternatives to minimize or avoid conflict between food and fuel production. Biomass for energy is both "part of the problem and part of the solution." It proposes a holistic approach: a new paradigm that takes full account of the diverse and complex nature of biomass energy sources and states that the fundamental underlying causes are social injustice, inequality, waste, and so forth, rather than land competition for food and fuel.

“…Ethanol produced from sugarcane, corn, and other crops is used as a gasoline substitute or supplement for automobiles in many countries (Walter et al, 2008). Lignocellulosic biomass is a potential source for the growing demand for fuel ethanol, as the excess utilization of crops for ethanol production impacts the global food supply; however, a number of challenges impede its industrial application (Balat et al, 2008;Chen and Qiu, 2010).…”

Ethanol production from a mixture of wheat flour or potato tubers and cheese whey was examined using the flex yeast Kluyveromyces marxianus KD-15, a 2-deoxyglucose-resistant mutant of strain NBRC 1963 that can produce ethanol from sugar beet thick juice diluted with whey. Strain KD-15 simultaneously converted glucose and lactose to ethanol within 48 h, in media containing 10.0% to 15.0% (w/v) total sugars from saccharified filtrate and whey. For efficient production of ethanol from 15.0% (w/v) total sugars, KD-15 cells were collected after fermentation and inoculated into fresh media. Batch fermentation was successfully repeated at least ten times in medium composed of saccharified potato tubers mixed with whey. Yeast cells began to convert all the sugars to ethanol within 24 h, accompanied by cell propagation after the third batch.

“…It is mostly used as blending agent with gasoline (gasohol) to increase octane and cut down carbon monoxide and other smog-causing emissions [1]. Besides ethanol, butanol began to attract people's attention as a next-generation biofuel.…”
