Waste tyre pyrolysis – A review - ScienceDirect
Waste tyre as feedstock for pyrolysis The proximate analysis of any fuel gives its amount of moisture, volatile matter, fixed carbon and ash. It has been reported that the volatile matter of the tyre consists mainly of polymeric compounds that come from NR and SR, whereas the fixed carbon should match with the CB used in tyre manufacturing.
