Brazil produces approximately 40 million tires annually and discards over 450,000
tons within the same period. Improper disposal turns tires into an environmental
liability; each unit can take about 600 years to decompose in nature. This can
cause environmental damage and contribute to disease proliferation by creating
mosquito breeding grounds, including vectors for Dengue, Zika virus,
Chikungunya, and Yellow Fever. To mitigate these damages, Block Selantes was
founded in 2018. The company utilizes discarded tires to produce automotive
sealants that prevent punctures and tire wear. It is the only company globally
to use recycled tires as a sustainable raw material for sealants, a process
protected by an industrial patent, resulting in a unique product fully
compatible with tire rubber. Additionally, using the sealant in automotive
applications significantly enhances vehicle operation safety, reduces costs, and
improves logistical efficiency. The use of recycled raw materials also reduces
CO2 emissions and generates carbon credits for logistics operators. This paper
details the tests and results obtained during the technical validation of the
sealant when applied to commercial passenger and cargo vehicles.
