Scrap tires are accumulating in large volumes causing a growing threat to the environment. In order to eliminate this negative effect of these depositions and in terms of sustainable development, there is a great interest in the recycling of these non-hazardous wastes. However, the possibility of using rubber from damaged tires in many civil engineering works has been studied for more than 30 years. While the applications where these tires can be used and where the addition of rubber tires has proven to be efficient in protecting the environment and conserving natural resources, including the production of cement blends, road construction and geotechnical works . The recycling of tires in the applications mentioned above represents a means of disposal suitable for environmental and economic reasons.
Disposal of waste tires is becoming a major waste management problem around the world. It is estimated that 37 million tires for cars and trucks are discarded annually and that this number will increase by an additional 40% for 2011 and 72% by 2021, in line with the growth of road traffic and car ownership.
It is estimated that 11% of post-consumer tires are exported and 62% are reused, recycled or sent for energy recovery and 27% are sent to torn tires, whole tires or unloaded in illegal landfills. The landfill method is one of the most convenient ways to dispose of waste tires. Although rubber tires are extremely durable and are not naturally biodegradable, they will still remain in landfills with very little degradation over time, presenting a continuous environmental risk. Therefore, there is an urgent need to identify alternative solutions online to run the waste management hierarchy. This promotes recycling before disposal and recovery of energy.
