What Happens When You Recycle A Tire

By George Dodson


There are millions of cars on the road today. All the cars need tires. Tires are available in all shapes and sizes. Tires are required for both small and large vehicles. One thing is for sure, these tires wear out. When that happens you have some decisions to make. It is required to do something with it. The tire outlets generally take those tires off when you replace old tires. They discard them sometimes. These tires are put up for sale for people looking for spares.

What happens when a tire is recycled?

Tires are considered to be the largest sources of waste. Most of the states are dotted by large tire firms. These huge lots contain thousands of tires. These tires are of little use. They can be ground up and turned to what is termed ?crumb.? They are generally used as filler.

Most of the landfills do not want used tires. As a result of decomposing waste material, it can trap large amounts of methane gas. It then becomes buoyant and rise to the surface. Most landfills have liners that keep the contents from damaging the groundwater in the area. Tires tend to upset this process.

Research is done to figure out new uses of these tires. Ground up tires can also be used as fillers. They can also use this byproduct as a cap on landfills. The main convenience is that the tires can be shredded onsite.

Apart from landfills, tires are also used in hot melt asphalt. This product is used in replacement asphalt. Those crumbs are also used in certain kinds of concrete as a filler. Old tires are sometimes used by people in home and gardens. They make flowerbeds from them. They use the grindings as mulch in gardens.

New processes such as Pyrolysis can used to turn old tires in the fuel gas. Devulcanization is the method commonly used for turning old tires into crumb. This material can be used in making new tires. It reduces raw material costs.

In this process the tires are heated in a huge vessel in an oxygen free environment. The rubber softens and breaks down into smaller molecules. The molecules then vaporize leaving the reactor. The vapors can also be used as a power source. Most of the companies use this process. It is of great help for both the environment and the companies.
