“…Tires are usually composed of natural rubber (NR) (20-25%), styrene-butadiene rubber (SBR) (30-50%), butyl rubber (BR) (up to 30%), carbon black (CB) (around 30%), sulphur (1-2.5%), and small quantities of organic and inorganic additives [4,5]. Due to the fact that rubber tires contain a significant amount of carbon black, and have a heating value greater than coal (approximately 35 MJ/kg), discovering a way to benefit from their great energetic and raw material potential became the objective of many alternative fuel studies [6].…”

“…Additionally, incineration has not been shown to be an acceptable method to treat waste tires due to toxic gasses emission (volatile organic compounds-VOC, CO, CO 2 , dioxins, dioxin-like compounds,) and particulates [8]. In that respect, pyrolysis is considered to be one of the optimal approaches of decreasing, if not solving, waste tire concern, since this disposal method allows for the retrieval of valuable products from used tires: pyrolytic oil, which can be used as fuel, gas with high caloric value, which can further fuel the pyrolytic process, and a residual char (solid residue) usable as a smokeless fuel, carbon black, or activated charcoal [4,9].…”

Pyrolysis is an optimal thermochemical process for obtaining valuable products (char, oil, and gas) from waste tires. The preliminary research was done on the three groups of samples acquired by cutting the same waste tire of a passenger vehicle into cylindrical granules with a base diameter of 3, 7, and 11 mm. Each batch weighed 10 g. The heating rate was 14 °C/min, and the final pyrolysis temperature was 750 °C, with 90 s residence time. After the pyrolysis product yields were determined for all of the three sample groups, further research was performed only on 3 mm granules, with the same heating rate, but with altered final pyrolytic temperatures (400, 450, 500, 550, 600, 650, 700, and 750 °C). The results of this study show that thermochemical decomposition of the waste tire sample takes place in the temperature range of 200–500 °C, with three distinct phases of degradation. The highest yield of the pyrolytic oil was achieved at a temperature of 500 °C, but further heating of volatile matters reduced the oil yield, and simultaneously increased the yield of gas, due to the existence of secondary cracking reactions. The analysis of pyrolytic oil and char showed that these products can be used as fuel.

“…Nearly 1 billion of waste tire rubber is accumulated each year in the world, and it breaks down hardly in the natural environment. [8][9][10] The disposal of it is difficult to be realized, and it will bring about a series of environment problem if with an inappropriate management. A pyrolysis process with the purpose of fuel production has been seen as an economically and environmentally acceptable way for disposing the waste tire rubber.…”

“…Thus, recycling plastic helps create eco-friendly products and avoids putting tons of waste into said landfills [14]. Each year 1.3-1.5 billion tires complete their life cycle all over the world [15]. Thus, the use of waste derived fuels by cement plants will also be beneficial to the environment [16].…”

This project aims to present a methodology to establish the biomass content of unused tires as a typical fuel in cement factories. To this end, between 2011–2016 samples were collected every 2 years (four surveys) to assess natural and synthetic rubber in scrap tires through the thermodynamic analysis. Ninety-six samples were used in the study, 803.6 tonnes of scrap tires, as fuel. Knowing the Spanish vehicle fleet and considering undifferentiated tires, it is possible to predict the biomass content. The methodology has also been evaluated taking into consideration mono-brand samples. The simplicity of the methodology makes it possible to apply it in different regions and countries. New materials included in current and future tires will require constant samples and an assessment of the formulae state. Lastly, the biomass content in non-conventional fuels and its use in the cement sector will reduce CO2 emissions in said sector, with significant economic implications for it is regulated by the 2003/87/EC Directive, with up to 2792.91 tonnes of CO2 reductions.
