“…Pyrolysis (also known as chemical recycling) has demonstrated to be a viable route for ST valorization, as it effectively converts wastes into high added-value products, such as chars and other materials, that can be used in different industries in a wide range of applications [3][4][5]. Among the possible applications for ST-derived chars, their singular properties turn them into potential adsorbents for the removal of pollutants from contaminated wastewaters [5][6][7][8].…”

A char produced from spent tire rubber showed very promising results as an adsorbent of Remazol Yellow (RY) from aqueous solutions. Spent tire rubber was submitted to a pyrolysis process optimized for char production. The obtained char was submitted to chemical, physical, and textural characterizations and, subsequently, applied as a low-cost adsorbent for dye (RY) removal in batch adsorption assays. The obtained char was characterized by relatively high ash content (12.9% wt), high fixed-carbon content (69.7% wt), a surface area of 69 m2/g, and total pore volume of 0.14 cm3/g. Remazol Yellow kinetic assays and modelling of the experimental data using the pseudo-first and pseudo-second order kinetic models demonstrated a better adjustment to the pseudo-first order model with a calculated uptake capacity of 14.2 mg RY/g char. From the equilibrium assays, the adsorption isotherm was fitted to both Langmuir and Freundlich models; it was found a better fit for the Langmuir model to the experimental data, indicating a monolayer adsorption process with a monolayer uptake capacity of 11.9 mg RY/g char. Under the experimental conditions of the adsorption assays, the char presented positive charges at its surface, able to attract the deprotonated sulfonate groups (SO3−) of RY; therefore, electrostatic attraction was considered the most plausible mechanism for dye removal.

“…As other ELVs residues, the landfill disposal of end-of-life tyres poses a serious environmental threat. Alternatively, recycling and thermal treatment (co-combustion in cement kilns, pyrolysis, gasification) are applied (Kindzierski et al, 2010;Naveed et al, 2011;Antoniou et al, 2014).…”

“…Literature review concerning production of pyrolytic oils form waste tyres was made by Hita et al [5]. In turn, Antoniou et al [6] critically analysed activated carbon production form char. It is important to note that when comparing with traditional waste management of tyres such as combustion, pyrolysis provides lower emissions of pollutants such as polycyclic aromatic hydrocarbons, volatile organic compounds and CO2, thus it can be considered as an environmentally respectable solution [7][8][9].…”

Nowadays, the stability of energy supply that additionally should be sustainable is one of the most important global issues. Thus, many new potential energy sources are being investigated. Since automobile industry is growing, a huge amount of waste tyres (WT) occur each year. Pyrolysis of scrap tyres can be considered as a sustainable way to recover significant amounts of energy as well as the valuable materials. Potential of waste tyres in the energy sector is studied in this work. Proximate, ultimate and thermogravimetric (TG) analysis of mechanically grounded WT sample was done. Waste tyres feature high heating value combined with carbon content as high as 87.90 % (on dry ash-free basis). Additionally, TG analysis allows to choose optimal operating temperature for pyrolysis process which is between 350 and 500°C. However, the sulphur content is also relatively high – around 2 wt.% - and it is the most important challenge for utilizing this waste in a thermochemical way.
