• Resumen

  • The biofuel incorporation in fossil fuels is a measure that promotes energy sustainability and reduction of fossil fuels dependency. The European Union established a target of incorporating 14% renewable energy in the transport sector by 2030. The biodiesel is one of the most widely used biofuel in Europe mainly from vegetable oils. Land use to grow biodiesel feedstock may have negative environmental impacts. It is necessary to look for an alternative feedstock for biodiesel production that consider the sustainability, and which can contribute to the decar-bonisation. The wastewater contains fat, oil and grease (FOG) that can be used in the biodiesel production to reduce the carbon footprint and to promote the circular economy. This work analyses the potential of biodiesel production from FOG collected in WWTP. Considering the quantity and quality of FOG separated, it can be verified that this may be an important alternative feedstock for biodiesel production.
