In this review, a summary of current legislation applicable to End-of-Life Tyres (ELTs), management of that waste, both in Spain and Europe, and a compilation of existing technologies to enlarge the life of tyres and treatment technologies for material and energy recoveries, are provided. In recent years, there have been a number of studies in the field of treatment of ELTs, therefore applicable emerging technologies as more efficient, clean and costeffective technologies, are discussed. KeywordsEnd-of-Life Tyres (ELT); Retread; Material recovery; Energy recovery; Integrated Management System (IMS). reciclado de neumáticos fuera de uso. revisión tecnológica resumenEn este trabajo, se realiza un resumen de la legislación actual aplicable a los Neumáticos Fuera de Uso (NFU), de la gestión de dicho residuo tanto en España como en Europa y una recopilación de las tecnologías existentes para la prolongación de la vida útil de los neumáticos y de las tecnologías de tratamiento para su valorización material y energética. En los últimos años, han sido numerosos los estudios realizados en el campo del tratamiento de los NFUs, por ello se ha realizado una búsqueda de las tecnologías emergentes, como posibles tecnologías más eficientes, limpias y económicas.

“…However, this drops to 38%, 8% and 6% in Germany, France and Britain, respectively. The clinker obtained from TDF by 20% substitution of conventional fuel is similar to that obtained using only pet coke (Trezza and Scian, 2009). To date, there are no scientific data that show a decline in the quality of the final product using this fuel.…”

The new challenges of end-of-life tyres management systems: A Spanish case study

et al. 2013

View full text Add to dashboard Cite

Directive 2008/98/EC released by the European Union represents a significant step forward in all relevant aspects of waste management. Under the already established, extended produced responsibility (EPR) principle, new policies have been enunciated to continuously achieve better overall environmental performance of key products throughout their life phases. This paper discusses how the directive is being articulated in Spain by the main integrated management system (IMS) for end-of-life (EOL) tyres since its creation in 2006. Focusing on the IMS technological, economic and legal aspects, the study provides a global perspective and evaluation of how the IMS is facing the current issues to resolve, the new challenges that have appeared and the management vision for the coming years.

“…Currently, there is much interest in using these materials for energy generation. Tire-derived fuels (TDFs) are used as substitutes of fossil fuels in the concrete industry [9][10][11] and in combustion processes for the generation of electric power, e.g., by boilers in the paper manufacturing industry, by industrial boilers and by power stations, etc. [12].…”

This paper reports the pyrolytic treatment of granulated scrap tires (GST) in a pilot distillation unit at moderate temperature (550°C) and atmospheric pressure, to produce oil, char and gas products. Tire-derived oil is a complex mixture of organic C(5)-C(24) compounds, including a very large proportion of aromatic compounds. This oil has a high gross calorific value (∼ 43 MJ kg(-1)) and N and S contents of 0.4% and 0.6%, respectively, falling within the specifications of certain heating fuels. The distillation gas is composed of hydrocarbons; methane and n-butane are the most abundant, investing the distillation gas with a very high gross calorific value (∼ 68 MJ Nm(-3)). This gas is transformed into electric power by a co-generation turbine. The distillation char is mostly made of carbon but with significant inorganic impurities (∼ 12 wt%). The quality of the solid residue of the process is comparable to that of some commercial chars. The quantity of residual solids, and the qualities of the gas, liquid and solid fractions, are similar to those obtained by conventional pyrolytic treatments of waste tires. However, the simplicity of the proposed technology and its low investment costs make it a very attractive alternative.
