“…In spite of previously demonstrated that the mobility of these heavy metals is suppressed in the extracted pyrolysis chars (Bernardo et al, 2010) the leachability of these heavy metals has to be monitored and strategies for removing them have to be evaluated.…”

“…However, it was previously demonstrated that Zn mobility/leachability (Bernardo et al, 2010) is suppressed in the extracted pyrolysis chars. Also, previous studies (Hwang et al, 2007;Kistler et al, 1987) have shown that pyrolysis may have a positive effect on the immobilization of heavy metals in solid chars.…”

Summary: The present work is devoted to the study of chars obtained in the co-pyrolysis of plastics, biomass and tyres wastes. The chars were extracted with several organic solvents in order to assess the more efficient in reducing the organic load of the chars and, therefore, their toxicity. The ability of each selected extractant to remove toxic pollutants was evaluated by comparing the extracts yield and thoroughly characterizing the different crude extracts obtained by combining chemical analysis and toxicity bioassays. Also, the mineral composition of the treated and non treated chars was assessed. The results will allow to conclude which solvent should be used in the decontamination of the pyrolysis chars.

“…A literature review revealed that the majority of articles that are related to end-of-life (EOL) tyres, when considering the new European Directive 2008/98/EC (European Union, 2008), focus mainly on technical solutions (Aiello et al, 2009;Aylón et al, 2010;Bernardo et al, 2010;Donatelli et al, 2010;Sang Son et al, 2011;Shulman, 2011;Singh et al, 2009). With regard to the application of this new directive, other articles are based on an assessment of waste management technologies according to the waste hierarchy identified in this Directive (Generowicz et al, 2011), or alternative treatment technologies that have been evaluated on their cost aspects, product utilization and compatibility with the EU waste framework that was proposed in the mentioned directive (Donatello et al, 2010;Grosso et al, 2010).…”

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.
