A recent article conpared the full life cycle assessment of biobutanol and Butanol can be used in an unmodified gasoline engine [103] and in diesel engines [96]. Just like second generational bio-ethanol, bio-butanol is also a renewable fuel that can be produced from lignocellulose biomass through acetone butanol ethanol (ABE) fermentation (Garca et al 2011). Wood, Gas, Electric, Pellet or Alcohol? The Technology Revolutionizing Commercial Waste Management, Food Waste Management Consumer Behavior and Food Waste Disposers, Anaerobic Digestion: An Option for Organic Waste Management, Home-produced biogas is a promising, sustainable technology. In addition to butanol, these organisms also produce acetone andethanol, so the process is often referred to as the ABE fermentation. Besides that, compare to ethanol, butanol has the following advantages (Drre 2007): However, there still existing some issues in the productions and utilizations of bio-butanol (Jin et al 2011): From the above illustration, we can see that although bio-butanol still need some further developments, since it still has some issue. Like ethanol, it can be produced fermentatively or petrochemically. The problem with this type of microbe is that it is poisoned by the very butanol it produces once the alcohol concentration rises above approximately 2 percent. Not only is biobutanol a higher-grade more energy dense fuel, but it is also less explosive than ethanol. Such as petrol engines can work deprived of any modification any on biobutanol. 1. Once considered usable only as an industrial solvent and chemical feedstock, biobutanol shows great promise as a motor fuel due to its favorable energy density, and it returns better fuel economy and is considered a superior motor fuel (when compared to ethanol). Compared to gasoline, greenhouse gas emissions are reduced because plants capture carbon dioxide from the air through photosynthesis and are then released back into the atmosphere when biobutanol is burned.
