Description
Summary: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.
