  The proposal ofBiofuel as eco-efficient fuel solution in the ‘Airbus Fly Your Ideas Challenge 2011’ towards the dream of green future aviation. The Idea and Origin The idea is to introduce environmentally sustainable aviation fuel as alternative Fuel solution: Biofuel- Algea and Bimass fuel. Algea: The algae plant that secrets a substance similar to crude oil. Both of these are tremendously exciting. they are renewable and, since they come from plants, help to deplete CO2 that their usage puts into our sky. And the change towards green aviation can start now! Algea in microscope Production- Algae Oil is the result of the process of growing the algae microorganism to sufficient mass that it can be harvested and processed through a system where the walls of the single cell organism are caused to burst, releasing the hydrocarbon liquid (Lipin) contained within the cell. This oil is collected and processed to reduce the percentage of water in the oil to the point that it is usable in the transesterification process whereby biofuel is produced. Producing fuel in laboratory; Biophotolysis Biomass: Fuel from biological waste material. There are varied waste as wood products, paper, food scraps, forestry waste, agricultural residues, industrial, residues, animal by- products, sewage, municipal solid waste and even tyres, which through various processes can potentially be turned into biofuel.

  Production- Can beproduced by feeding waste into a patented high temperature gasifier, producing what it called BioSynGas. The established Fischer-Tropsch process then converts the gas into jetfuels. Potential benefits According to various technical reports, second generation bio-fuels are feasible for the industry. Increasing demand together with higher oil prices, will make alternative resources very attractive. • Environmental benefits: sustainably produced biofuels result in a reduction in CO2 emissions across their lifecycle. For example, one of the biggest advantages of algae for oil production is the speed at which the feedstock can grow. It has been estimated that algae produces up to 15 times more oil per square kilometre than other biofuel crops. Another advantage of algae is that it can be grown on marginal lands that aren’t used for growing food. • Diversified supply: second-generation biofuels offer a viable alternative to fossil fuels and can substitute traditional jet fuel, with a more diverse geographical fuel supply through non-food crop sources. • Economic and social benefits: sustainable biofuels provide a solution to the price fluctuations related to fuel cost volatility facing aviation. Biofuels can provide economic benefits to parts of the world, especially developing nations, that have unviable land for food crops that is suitable for second-generation biofuel crop growth. Green-fuel revolution:Natural Bio- resources in different parts of the world for example is a clear indication of growing up huge Bio-industrial beginning very soon. Oceans can be the major resources for biofuel Development Biofuels can provide a much expected substitute for future green aviation concept.This can contribute climate and other positive environmental goals, energy security, air traffic development and other opportunities for airlines to profit. Engine modification:The fuel has a high viscosity and so may thicken in winter; thereby causing cold-starting problems. This can be solved by using antifreeze additives with the fuel in winter, or the use of engine heaters to warm the fuel via convection. Emissions can be

  improved by remappingthe engine-control unit to adjust the timing and injection pressure of conventional jet engines. Keeping Blue skies blue Supporting biofuel market: By encouraging existing and future bio-fuel producers, companies and farmers. Help implementing low business taxes to grow and establish the market for aviation fuel to make available. International organisations such as the Roundtable on Sustainable Biofuels aim to give guidance and support to companies that are developing bio-fuels projects, as well as to those who are already in operation. Conclusion: Biofule perform well and no differently to engines totally fuelled with regular jet fuel. The more welcoming news so far is some popular airlines already made their first move towards greener flight. For example Air New Zealand, Continental Airlines and Japan Airlines have conducted successful test flights using a Jatropha and fossil fuel blend. Future bio-fuels test flights have been also announced by Jet Blue Airways and British airways.
