Characterization of fibers obtained from shredded tires

Abstract

The importance of recovering waste materials generated by industrialised societies is mainly due to the environmental impact they have, and one of the principal problem areas is tires. In recent years, an enormous amount of tires have been recycled. Metals contained in them have been recovered and the tire particles have been used in diverse applications. A third material that appears in the recovery process is the fibers, which act as reinforcement. Before addressing the possible reuse of these fibers, it is necessary to characterise and identify them. The diverse techniques of thermal analysis allow these fibers to be identified through melt point analysis, the results of which show the presence of polyamide 6 and 6.6. Moreover, the combination of pyrolysis‐gas chromatography/mass spectrometry corroborates the identification made with the techniques previously mentioned and also indicates the presence of certain additives used in the manufacture of tires, such as resorcinol and benzothiazole. © 2009 Wiley Periodicals, Inc.

Identification of polymers in waste tyre reinforcing fibre by thermal analysis and pyrolysis

“…In addition the thermal decomposition of elastomers that are also present in tyre rubber has been studied in depth [11][12][13][14]. Yet so far the reinforcing fibre that is recovered as a waste in tyre shredding factories has received little attention [15][16][17][18]. The aim of the present work is to identify the fibres that are present in the waste recovered from tyre grinding factories to help in finding a use for this waste.…”

Fuel-oils from co-pyrolysis of scrap tyres with coal and a bituminous waste. Influence of oven configuration

“…The reinforcing fibre is usually recovered as a heterogeneous fluff made up of polymeric fibres that contain a certain amount of rubber [3,10,11]. Until now little effort has been devoted to finding a procedure for recycling this fluff.…”

Preparation of MgO-templated carbons from waste polymeric fibres

“…oxidation, carbonization and activation. The results of this study prove that it is possible to 10 20 produce nanocarbons from a bituminous waste and waste fibres without the need for activation. In order to confirm the mechanism of formation of the porous texture, SEM images are presented in Fig.…”

“…RF was obtained from the processing of car and truck tyres [1] and is mainly composed of polyester and polyamide [9,10]. The main characteristics of these materials are presented in Table S1.…”
