Abstract

The inadequate disposal of rubber tire waste represents a significant environmental problem, with an annual production of 1.5 billion units of waste. The present Systematic Literature Review study sought to identify new technologies for the utilization of rubber tire waste, focused on the circular economy model. The PICOC methodology was used to formulate the research question and develop a search equation, allowing the collection of various articles in the Scopus and ScienceDirect databases, and then using the PRISMA methodology, inclusion and exclusion criteria were established, obtaining 31 articles. The results obtained indicate that the most promising technologies include pyrolysis, gasification, combustion and their use in the production of construction materials. Pyrolysis stands out for its efficiency in transforming tires into higher value by-products, while gasification and combustion stand out for helping to reduce greenhouse gas emissions, so it is necessary to implement these treatments for proper management of waste from rubber tires. It is concluded that the implementation of technologies focused on the circular economy model is essential to maximize the value of tire waste, given that its implementation is an effective solution that mitigates environmental impacts and optimizes the use of available resources.
