Its disposal, in some cases illegally, increases the cost and the energy consumption of domestic wastewater treatment, as well as the GHG emissions associated with its biodegradation (non-CO2 emissions). Moreover it should be added the heavy environmental pollution load. The European initiative RecOil (Promotion of used cooking oil recycling for sustainable biodiesel production), co-funded by the Intelligent Energy Europe programme of the European Commission, aims to increase sustainable biodiesel production and its market intake by enhancing the household used cooking oil (UCO) collection and transformation at local and regional level. RecOil will assess the “UCO to biodiesel” chain best practices, through a household survey, acknowledging the industry expertise, and local/regional authorities’ cooperation, to develop an on-line decision-making guide in order to assist stakeholders in developing a chain adjusted to local specificities (geographic, social, economic, legislative, and climate). Pilot projects will also be implemented, according to the most promising practices identified, for validation. The RecOil implementation will result in primary energy savings estimated in 1.300 toe/year and the reduction of GHG emissions 14.413 tCO2.http://creativecommons.org/licenses/by/4.0/305-310Energy for Sustainability 2013 Sustainable Cities: Designing for People and the Planet, At Coimbra, Portugal Dalila Antunes Stavroula Tournaki Orlando Paraíba Tsoutsos Theocharis Τσουτσος Θεοχαρης
