The aim of the study was to identify and discuss the valorization pathways of tires, automotive shredder residues (ASR) and lignocellulosic biomass waste pyrolysis products. The adopted approach has provided the definition of several indicators (Inlet waste characteristics, pyrolysis technology, char quality, pyrolysis oil quality, and gas quality) able to depict the main characteristics of the pyrolysis products. An extensive literature review allowed the assignment of values to each indicator. Results showed how pyrolysis oils and char are the most searched products for tires and biomass waste. Gas valorisation, on the other hand, seems to be of little importance for tires. Instead, for the ASR, pyrolysis is mainly directed towards char production although a scenario of uncertainty has been observed highlighting no clearly valorisation paths for ASR pyrolysis products.

Abstract
The aim of the study was to identify and discuss the valorization pathways of tires, automotive shredder residues (ASR) and lignocellulosic biomass waste pyrolysis products. The adopted approach has provided the definition of several indicators (Inlet waste characteristics, pyrolysis technology, char quality, pyrolysis oil quality, and gas quality) able to depict the main characteristics of the pyrolysis products. An extensive literature review allowed the assignment of values to each indicator. Results showed how pyrolysis oils and char are the most searched products for tires and biomass waste. Gas valorisation, on the other hand, seems to be of little importance for tires. Instead, for the ASR, pyrolysis is mainly directed towards char production although a scenario of uncertainty has been observed highlighting no clearly valorisation paths for ASR pyrolysis products.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
