1. In landfills: Car tires can take hundreds of years to decompose in landfills. The lack of oxygen and slow microbial activity in landfills create conditions that slow down the decomposition process.
2. On the ground: When exposed to the elements on the ground, car tires can take anywhere from 50 to 100 years to decompose. Factors such as sunlight, moisture, and temperature affect the rate of decomposition.
3. In water: Car tires that end up in water bodies, such as oceans or lakes, can take even longer to decompose. They can remain intact for hundreds of years due to the lack of oxygen and cooler temperatures underwater.
It is important to note that the decomposition time mentioned above are general estimates and can vary significantly based on specific conditions and environmental factors. Proper disposal and recycling of car tires is essential to minimize their environmental impact and prevent the accumulation of hazardous waste.
