Researches on the Advantages for the Environment of Using Bio-Fuels to Vehicles

subject

description

The paper presents researches on the possibilities and advantages for the environment of using bio-fuels , especially bio-ethanol and bio-gas. The international context is favorable to using bio-fuels, considering that a direction of European Union establishes that in 2020, 20% of the energy consumption of Romania must be provided by rechargeable energy. One source for producing bio-fuels, not so much used until now is sugar beet. Sugar beet wastes are estimated as 1.22 times sugar production, since the total dry matter of processing wastes and field wastes exceed the weight of sugar in the ratio of 55:45. The novelty of the present paper approach is the fact that sugar beet is less used for producing bio-fuel, although its energetic efficiency is bigger than that of some of much studied bio-fuels, such as bio-diesel. Other advantages presented by sugar beet as bio-fuel is the fact that the technology can be completely mechanized, the possibility of preserving it for long periods of time as syrup and a very good efficiency. On the other hand, are presented the compared quantities of bio-gas obtained from different materials, from which resulted that sugar beet leafs have the best quantity of methane from bio-gas. The paper presents a big degree of practical applying and contains original researches. Another aspect which is worthy to be considered is that the emissions released by a motor using bio-ethanol are considerable less than that of a motor using conventional fuels.
