Using fruits and vegetables for fuel

           This article talks about  an alternative production for fuels. Gary Hawkins studied rotten vegetables and fruits. His goal is to put waste products into good use and for  growers and packing houses to produce their own natural gas. As vegetables and fruits degrade it can be harvested for natural gas and methane. It can fuel electricity producing generators. The gas that it provides can heat up greenhouses, homes, stores, etc. Produce is not all equal when it comes to methane producing potential. Some produce more methane than others. For fruits Hawkins  concluded that blueberries had the  highest potential for methane production and the highest energy density. For vegetables he concluded that onions had the highest potential for methane production and the highest energy density. Hawkins used anaerobic digester to convert the decomposing fruits and vegetables to methane. Oxygen is absent and bacteria are present in these anaerobic digester containers. The bacteria inside these containers can easily be killed if the produce is to acidic.                                        Another relevant article explains how fructose converted to fuel is more advantageous than ethanol. Dimethylfuran can store 40% more energy than ethanol. Fructose can be abstracted from fruits or made from glucose. This process still has much more assessing to do for the environment.
