A Review of the Advances in Biofuels Production

Paula-Bianca MARICA

Abstract


The finitude of fossil fuels, the concerns for energy security and the need to respond to climate change have led to growing worldwide interest in biofuels. Biofuels are often viewed as a key to reducing reliance on foreign oil, lowering emissions of greenhouse gases and meeting rural development goals. Biofuel is defined as solid, liquid or gaseous fuel derived from relatively recently dead biological material and is distinguished from fossil fuels, which are derived from long dead biological material. Biofuels are alternative renewable fuels that have received considerable attention in the recent past namely: bioethanol, which is made from crop grains or sugarcane and biodiesel, which is made from vegetable oils and animal fats. They are both used as a source of power for cars, trucks, and aircrafts. Theoretically, biofuels can be produced from any biological carbon source, although the most common sources are photosynthetic plants. This paper highlights the on-going developments in biofuel feedstock selection and production technologies, evaluating the environmental and economic effects of biofuels use.
