In this review, a summary of current legislation applicable to End-of-Life Tyres (ELTs), management of that waste, both in Spain and Europe, and a compilation of existing technologies to enlarge the life of tyres and treatment technologies for material and energy recoveries, are provided. In recent years, there have been a number of studies in the field of treatment of ELTs, therefore applicabl...

Approximately 1.5 billion tyres are produced each year which will eventually enter the waste stream representing a major potential waste and environmental problem. However, there is growing interest in pyrolysis as a technology to treat tyres to produce valuable oil, char and gas products. The most common reactors used are fixed-bed (batch), screw kiln, rotary kiln, vacuum and fluidised-bed. Th...

The paper presents a static lateral stability of sub-compact tractor MT8-070 Mini in relation to safe operation. Axle weight distribution the was measured calculate vertical and longitudinal coordinates centre gravity (COG). Experiments were aimed at equipped with no four levels rear wheel ballast weights (30.5, 61, 91.5 122 kg) standard extended overall width on tyres. A overturning angle calc...

Results and Conclusion: In this study, a numerical two-permeability flow model was used to investigate the effects of tyres embedding on the outflow rate of leachate injection. Furthermore, it was coupled with momentum balance equations to determine the local factor of safety of slope stability. The established model was applied to a simplified bioreactor landfill. The simulation results demons...

The paper applies to the issue of preservation of passenger vehicles during overcoming the roadblocks on a dry asphalt surface with the constant speed. The study aimed to estimate the forces which are affecting the suspension of the vehicle during the contact between a tyre and roadblock. Using the video recording it is possible to calculate the values of the tyre deflection and forces acting i...

Wear and tear from tyres significantly contributes to the flow of (micro-)plastics into the environment. This paper compiles the fragmented knowledge on tyre wear and tear characteristics, amounts of particles emitted, pathways in the environment, and the possible effects on humans. The estimated per capita emission ranges from 0.23 to 4.7 kg/year, with a global average of 0.81 kg/year. The emi...

The influence of catalyst support alumina-silica in terms of different Al2O3 to SiO2 mole ratios containing 20 wt.% Ni on the production of hydrogen and catalyst coke formation from the pyrolysis-catalysis of waste tyres is reported. A two-stage reactor system was used with pyrolysis of the tyres followed by catalytic reaction. There was only a small difference in the total gas yield and hydrog...
