General Motors thinks green
General Motors is thinking green. They are developing a new method of making ethanol thus addressing some of the environmental concerns usually associated with producing biofuels. Challenging old techniques the fuel will negate the process of making ethanol from grain. Instead, the fuel will be made from a wide variety of waste materials, such as wood chippings, food waste and even used tyres.
General Motors claims the process of making fuel from waste materials will significantly lessen the use of water and energy. The process is pioneered by US based company Coskata who even boasts of new process being energy efficient compared to the old technique. According to the new process one unit of energy used in production produces 7.7 units in ethanol form, which is an impressive figure.
So, to make 100 gallons of ethanol, Coskata just needs a ton of dry material and less than 100 gallons of water. According to sources General Motors is taking an equity stake in Coskata, but how much is not public information. GM will use the ethanol from demonstration plant at its Milford Proving Ground.
Most importantly, GM will be attempting to implement this technology globally. Both these firms would like to quickly commercialise this process. With this we hope to have the fuel for the future.
