“…In addition, since the 1970s increase in the (Buekens, 1977). Carrasco et al (1998) reported an increase in the emissions of sulfur dioxide (SO2) and carbon monoxide (CO) up to 30 and 47% from a cement plant using coal (80%) and tire waste (20%) respectively. Moreover, open burning of the tire waste increases the mutagenic factors by up to 3-4 times as compared to the use of coal, wood, or oil utility boiler (DeMarini et al, 1994).…”

 Catalytic and non-catalytic pyrolysis of tire waste was carried out at pilot-scale  Non-catalytic pyrolysis produced highest liquid oil as compared to catalytic pyrolysis  Natural zeolite, zeolite (H-SDUSY), Al2O3 and Ca(OH)2 catalysts were used  Use of various catalysts improved the quality of liquid oil  Oil from both processes mainly contained aromatic with some aliphatic compounds

“…For the most volatile elements of concern present in tire-derived fuel (lead and zinc), typically enriched in the finer particulate fractions following combustion, 9 the results observed can also be attributed to the high removal efficiencies developed by the FF over the particle size range of interest. They must be considered significant when compared to the observations of other authors, 10 who report significant emission increases for these two elements during tire utilization.…”

The present work outlines the main results of a full-scale study conducted on the utilization of waste tires as auxiliary fuel in cement production. Experimental tests were conducted for determining the influence of shredded tires on combustion conditions, emissions produced, and the characteristics of clinker obtained, for feeding ratios over 35% in terms of total heat input. The addition of tire chips did not lead to any appreciable modification in either the whole process or the quality of clinker produced; gaseous emissions were mostly unaffected, with significant improvements related to the reductions obtained in nitrogen and sulfur oxides concentrations. Experimental findings from tests conducted with tire chips exposed to kiln combustion flue gases compare favorably with the typical burnout times derived from theoretical approaches. These experimental data and calculations to estimate particle trajectories beyond the injection point, through proper theoretical analysis of the kinetic behavior, result in important indications for the shredding operation and for optimum injection modes.

“…The environmental impact from this process needs additional research, especially regarding to the generation of PAH (polycyclic aromatic hydrocarbons) in the exhaust gases. In 1998, Carraso et al [43] reported that energy retrieval from waste tires when used as fuel in cement industries, satisfy environmental standards. The effects of using of waste tires as fuel in cement production was evaluated by Giugliano et al [44].…”

Significant high levels of available waste tires in Brazil, which reached approximately 473 thousand tons in 2015, offer an attractive potential for their use as fuel in advanced thermal conversion processes. Technologies for energetic valorization of waste tires were reviewed and two alternatives based on updraft gasification in a modified reactor design were proposed. First of all, a large-scale updraft gasifier on IGCC (Integrated Gasification Combined Cycle) was considered for the gasification of the derived fuel from waste tires, capable to produce between 10.8 and 16.1 MJ of electric energy per kg of derived fuel from waste tires fed to the reactor. The second alternative considered a small-scale updraft gasifier feeding an internal combustion engine, coupled to an electricity generator for the production of up to 8.2 MJ of electric energy per kg of derived fuel from waste tires fed to the reactor. Implementation of these technologies will allow energetic valorization of waste tires in Brazil, solving their disposal problems, creating jobs, reducing negative disposal environmental impacts in landfills, and increasing distributed generation of electricity.
