Energy recovery from tyres waste through thermal option

Pyrolysis and combustion of worn out tyres are increasing options for their energetic valorization. In the present paper the elemental analysis and calorific values of a tyre are presented. Results from TG-MS/TG-GC-MS analyzer and labscale reactor tests are also reported. From the thermal decomposition of the tyre, a gas (20%), a tyre pyrolysis oil (TPO, 40%) and a solid char (40%) resulted. The TPO calorific values, HHV and LHV, resulted 49.5 and 46.7 MJ/kg, while for solid char were 34.7 and 33.7 MJ/kg, respectively. An example of process application is also presented in this paper.
