Used tires recycle management and processing: a review

Abstract

The number of used tires in the world is projected to increase in the future due to an incrementing number of cars and motorcycles particularly in developing countries such as Indonesia. This situation can endanger the environment and public health since it poses a high risk for fires. Despite the environmental impacts, used tires present economic values. This can be achieved by processing it into several forms such as tire-derived fuel, asphalt rubber, and rubber-plastic products. Furthermore, to collect used tires from tire users and send it into used tires recycler, management scheme is required. This paper aims to review the development of used tires recycle management and processing. It has been found that several management schemes for recycling used tires have been identified from literature including Extended Producer Responsibility (EPR), Free Market, and Government. Moreover, several processes to recycle used tires were identified, such as: retreading, energy recovery, product recycling, material recycling, and pyrolysis.

Use of Waste Tires as Transverse Reinforcement and External Confinement in Concrete Columns Subjected to Axial Loads

“…The increasing production of vehicles has led to a rise in worn-out tires, posing significant risks to the environment and public health [8]. Improper recycling practices result in the loss of the economic value of tires and contribute to wasteful land usage.…”

“…The hazardous chemical produced by scrap tires at junkyards and landfills impact the environment [7]. Obtaining the most efficient methods of recycling old tires helps to conserve the environment [8]. Energy recovery is a widespread practice for managing waste tires.…”

“…Because tire production is continually expanding, appropriate recycling of old tires is one of the most pressing concerns in the twenty-first century. Adequate tire management has necessitated the adoption of innovative technologies that improve recycling [8,10]. Improving recycling methods would aid in resolving the environmental issue posed by automobile tires.…”

Analysis of Noise Levels in Typical Passenger Cars

“…Manufacturers of passenger cars are required to use natural sources, as well as those from recycling, to obtain products for the production of vehicles. According to some researchers from the automotive industry [9,10], it goes unnoticed that rational waste management is conducive to minimizing negative impacts on the environment. In turn, several researchers have studied the issue of vehicle noise [11][12][13][14], and Cherry [15] has demonstrated active sound control technology that can be used to not only reduce noise in the car environment, but also improve driving comfort.…”
