The Redesigning of Tires and the Recycling Process to Maintain an Efficient Circular Economy

Abstract

The redesigning of tires is addressed from two points of view, namely the structure of the materials and the constructive shape of these products. The necessity for research is justified by the fact that even during the product design stage, there may be situations that can irreversibly affect the separation of product components (rubber and insertion), and because it is strictly necessary to achieve the reuse and recycling of waste components. The proposed redesign refers to the inscription of the types of materials that are present in each area on the lateral surface of the tire. Thus, the new redesign has positive effects both economically and socially. To highlight these, a cost-benefit analysis (CBA) has been applied and the net present value (NPV) as well as the internal rate of return (IRR) have been determined for the classic scenario and for the two proposed scenarios. Testing the financial sustainability of the proposed solution was done through sensitivity analysis. An analysis of the new tire design from the point of view of the circular economy was also presented. The results obtained have highlighted the effectiveness of the proposed solution from a technical, economic, social, and protection of the environment point of view.

Establishing Impact of the Long-Term Action of Waste Dumps with the Occurrence of Waste Tires on the Soil Environment

“…This type of utilizable waste should be given priority in handling (reuse, recycling, pyrolysis or use for energy) which would prevent contact of WT with the environment to necessary minimum [1]. Legislative frameworks should be properly adjusted and regulations should be made stricter to reduce as much as possible the illegal disposal of WT, to contribute at the same time to the recycling of WT and to meet goals of circular economy [10].…”
