New ecological process for producing cheaper biofuel

Professors Rajeshwar Dayal Tyagi and Patrick Drogui, researchers at the Institut National de la Recherche Scientifique (INRS), have developed a new approach to biodiesel production that uses microbes, sewage sludge, and a biofuel byproduct.  Biodiesel has multiple environmental benefits, but the use of vegetable or animal oils raises the food vs. fuel dilemma, the risk of diverting farmland or crops for biofuels production to the detriment of the food supply. Plants have been turning to microbial biodiesel, which can be made out of glucose using microorganisms. But at $6.78/L, the conventional production process is quite expensive.  Professors Tyagi and Drogui have brought the production cost down to $0.72/L with an innovative new process. Their findings—in order to assess the costs, energy, and greenhouse gas emissions (GHG) —were published in the journal Bioresource Technology, in Feburary.  Read more....
