The main goal of the VALORES project is to develop a profitable and scalable technology to enable the use of waste that is currently disposed of in landfills such as tires, plastics, and biomass. This technology will involve the pyrolysis of the products mentioned so that they can be used in Repsol Petróleo refineries, also providing raw materials that can be used in the petrochemicals industry. This goal is aligned with the promotion of the circular economy, the reduction of waste, and the European sustainability and resource efficiency objectives. This measure has had a significant social impact as these products contain pollutants that must be eliminated previously. Although alternatives do exist, it is necessary to develop a means by which to eliminate these pollutants efficiently in order to reach the necessary specifications for the various processes carried out in refineries and chemical plants. The VALORES project has received funding from the Centre for the Development of Industrial Technology (CDTI - IDI-20170695), co-financed by the European Regional Development Fund (ERDF) as part of the Smart Growth Operational Programme 2014–2020 with the goal of enhancing research, technological development, and innovation.
