Abstract: This project aims to present a methodology to establish the biomass content of unused tires as a typical fuel in cement factories. To this end, between 2011–2016 samples were collected every 2 years (four surveys) to assess natural and synthetic rubber in scrap tires through the thermodynamic analysis. Ninety-six samples were used in the study, 803.6 tonnes of scrap tires, as fuel. Knowing the Spanish vehicle fleet and considering undifferentiated tires, it is possible to predict the biomass content. The methodology has also been evaluated taking into consideration mono-brand samples. The simplicity of the methodology makes it possible to apply it in different regions and countries. New materials included in current and future tires will require constant samples and an assessment of the formulae state. Lastly, the biomass content in non-conventional fuels and its use in the cement sector will reduce CO 2 emissions in said sector, with significant economic implications for it is regulated by the 2003/87/EC Directive, with up to 2792.91 tonnes of CO 2 reductions.
