The recycling of waste tires is a critical issue in a society largely dependent on road transport. In the context of Greater S\u00e3o Paulo, where millions of vehicles circulate daily, the improper disposal of these tires represents a significant problem for both the environment and public health. This study focuses on the specific situation of the municipalities of ABCD Paulista and Mau\u00e1, highlighting the practices and challenges related to the management of waste tires.<\/p>\n\n\n\n

Environmental and Health Impacts of Waste Tires<\/strong><\/h3>\n\n\n\n

Among the solid waste generated by the population, tires, classified as special waste, are highly relevant in discussions about environmental and health impacts. Their durable and resistant structure, designed to withstand adverse conditions, makes them difficult to dispose of in landfills. Whole tires are not accepted in landfills because they tend to return to their original shape after compaction, compromising soil stability and taking up large spaces that are increasingly scarce in cities.<\/p>\n\n\n\n

In addition to the physical impact, when used tires accumulate, they serve as an ideal breeding ground for the Aedes aegypti mosquito, which transmits diseases such as dengue, zika and chikungunya, all of which are widespread in Brazil. The risk of fire is also significant, given that tires burn easily, releasing black smoke composed of a mixture of dangerous pollutants and an oily material derived from petroleum that can contaminate bodies of water, making the water unfit for consumption.<\/p>\n\n\n\n

The Situation of Waste Tires in Greater S\u00e3o Paulo<\/strong><\/h3>\n\n\n\n

The study aimed to quantify the number of unusable tires in the municipalities of ABCD Paulista and Mau\u00e1, and to characterize the problem of the final disposal of this waste. The research, based on a bibliographic survey and the application of questionnaires to those responsible for public cleaning services, revealed that most municipalities lack efficient programs for the disposal of unusable tires.<\/p>\n\n\n\n

Among the municipalities analyzed, only Santo Andr\u00e9 showed some level of commitment to the proper disposal of this waste, carrying out selective collection and sending tires for recycling. In contrast, municipalities such as S\u00e3o Bernardo do Campo, S\u00e3o Caetano do Sul, Diadema and Mau\u00e1 do not have specific collection or disposal programs for unusable tires, resulting in irregular disposal in vacant lots, landfills and bodies of water, aggravating environmental and health problems.<\/p>\n\n\n\n

Challenges in Estimating Waste Tire Generation<\/strong><\/h3>\n\n\n\n

The research concluded that it is not feasible to accurately estimate the amount of waste tires generated in the municipalities studied due to the lack of basic data on municipal urban cleaning services. The absence of a structured collection system and the common practice of clandestine disposal make it difficult to quantify this waste. This highlights the urgent need to implement municipal programs aimed at the collection, recovery and final disposal of waste tires.<\/p>\n\n\n\n

The situation is aggravated by the fact that unusable tires are not accepted in regular garbage collection, and are discarded in clandestine locations often unknown to municipal authorities. This practice contributes to the perpetuation of negative impacts on public health and the environment.<\/p>\n\n\n\n

Waste Tire Recycling Practices<\/strong><\/h3>\n\n\n\n

Recycling waste tires is essential to mitigate the negative impacts associated with improper disposal. The city of Santo Andr\u00e9 has implemented an innovative practice in which tires are shredded and mixed with crushed stone, and used in the drainage system for percolating liquids in landfills. This technique not only solves the problem of occupying space in landfills but also contributes to sustainable waste management.<\/p>\n\n\n\n

Tire recycling can be expanded to include other applications, such as asphalt paving, where shredded tires are mixed with asphalt, resulting in a stronger and more durable layer. This technique, already used in many parts of the world, could be adopted on a larger scale in Brazil, contributing to reducing the volume of waste and improving road infrastructure.<\/p>\n\n\n\n

Proposals to Improve the Management of Waste Tires<\/strong><\/h3>\n\n\n\n

To address the challenges of waste tire disposal and recycling, municipalities in Greater S\u00e3o Paulo must develop and implement specific programs for collecting and disposing of this waste. These initiatives should include:<\/p>\n\n\n\n
