1. Recycling: Many廢 tires are recycled to create new products. They can be broken down into crumb rubber, which is used in various applications such as:
- New tires: Ground-up rubber from old tires can be incorporated into new tire production.
- Rubberized asphalt: Recycled rubber can be mixed with asphalt to create rubberized asphalt, which is used in road construction.
- Playground surfaces: Rubber mulch or crumb rubber can be used as a safe and durable surface for playgrounds.
- Sports fields: Recycled tire rubber is also used in the construction of sports fields, such as running tracks and artificial turf.
- Other products: Rubber from old tires can also be used to manufacture a variety of products like rubber mats, hoses, shoe soles, and construction materials.
2. Retreading: In some cases, tires that have worn tread but are otherwise still in good condition may undergo retreading. During retreading, the old tread is removed and replaced with new rubber, extending the tire's lifespan.
3. Energy Recovery: Some old tires are used as fuel in energy recovery facilities or cement kilns. The tires' high heat value makes them a potential source of energy, generating steam or electricity.
4. Landfills and Stockpiling: In cases where recycling, retreading, or energy recovery are not viable, some old tires may end up in landfills or stockpiles. Proper management and disposal of scrap tires are essential to minimize environmental impact. Many regions have regulations and programs in place to ensure environmentally sound handling of end-of-life tires.
5. Illegal Dumping: Unfortunately, a small percentage of old tires may end up being illegally dumped in the environment, creating pollution and posing health risks. Proper disposal and recycling programs help mitigate this issue.
