It can achieve greenhouse gas savings up to 88% and at the same time reducing the disposal of a polluting waste. In addition, it does not provoke potential negative impacts that conventional biofuels may eventually cause linked to the use of arable land. For this reason, most policy frameworks favor its consumption. This is the case of the EU policy that double-counters the use of residue and waste use to achieve the renewable energy target in the transport sector. According to different sources, biodiesel produced from UCO could replace around 1.5%–1.8% of the EU-27 diesel consumption. This paper presents an in-depth thermoeconomic analysis of the UCO biodiesel life cycle to understand its cost formation process. It calculates the ExROI value (exergy return on investment) and renewability factor, and it demonstrates that thermoeconomics is a useful tool to assess life cycles of renewable energy systems. It also shows that UCO life cycle biodiesel production is more sustainable than biodiesel produced from vegetable oils. 000060634 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000060634 590__ $$a1.343$$b2015 000060634 591__ $$aENVIRONMENTAL SCIENCES$$b146 / 225 = 0.649$$c2015$$dQ3$$eT2 000060634 591__ $$aGREEN & SUSTAINABLE SCIENCE & TECHNOLOGY$$b5 / 6 = 0.833$$c2015$$dQ4$$eT3 000060634 591__ $$aENVIRONMENTAL STUDIES$$b62 / 104 = 0.596$$c2015$$dQ3$$eT2 000060634 591__ $$aGREEN & SUSTAINABLE SCIENCE & TECHNOLOGY$$b23 / 30 = 0.767$$c2015$$dQ4$$eT3 000060634 592__ $$a0.482$$b2015 000060634 593__ $$aGeography, Planning and Development$$c2015$$dQ2 000060634 593__ $$aRenewable Energy, Sustainability and the Environment$$c2015$$dQ2 000060634 593__ $$aManagement, Monitoring, Policy and Law$$c2015$$dQ2 000060634 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000060634 700__ $$0(orcid)0000-0002-6360-1159$$aTorres, C.$$uUniversidad de Zaragoza 000060634 700__ $$0(orcid)0000-0003-0702-733X$$aValero, A.$$uUniversidad de Zaragoza 000060634 7102_ $$15004$$2590$$aUniversidad de Zaragoza$$bDpto.
