Success in achieving these objectives will demonstrate, in general terms, the environmental, energetic, and economic sustainability of the management and evaluation of the used cooking oils produced in the city of Seville. Expected results: Demonstration of the technical and economic feasibility of the new production technology by testing at least 40m3 of the new biofuel. Four biofuel mixtures will be tested in one city bus taking three different routes.
Development of a prototype module for the production of methyl esters (99.5% purity) and glycerine (80% purity) from 55m3 of used cooking oils. Production of at least 40m3 of the new, high quality biofuel – meeting European standards (EN 14214)
Development of a glycerine-based production process of at least 4,000 litres of additive (glycerin esters) for use in biofuels. Reduction in the pollutant emissions of Seville’s city bus fleet for each of the four biofuels tested. The proportions of commercial diesel and new biofuel in the biofuels tested will vary. Quantitative evaluation of the reduction of the impact on global CO2 emissions, which can be achieved through the demonstration process, and also through the combination of collection of used cooking oils, the production of methyl esters and glycerol esters, as well as the use of this new biofuel in the urban transport. Considering the total fuel life-cycle CO2 emissions, the replacement of a proportion from 15% to 100% of fossil fuel with the new biofuel in the urban bus fleet will reduce global CO2 emissions up to 85%.
