Ethanol production in US is to a large extent done by processing corn fuel.However the process of corn cultivation requires significant input of land and energy ,in addition to raising the ethical question of trading food for fuel.In addition the green efficiency of ethanol produced from this method is low and this process may actually pollute the environment.Alternatives sources such as grass,wood require few resources for ethanol production but in turn need expensive processing technology.Coskata, a startup based in Warrenville is pioneering a radical method which it believes will reduce the processing cost associated with any organic material.This startup’s technology has caught attention of giants such as General Motors which is partnering with Coskata to help commercialization of the technology on a big scale.
