Tire Recycling: What Occurs

By George Dodson


There are so many cars found today. Tires are essential for all the cars. These tires come in all sizes and types. Tires are required for both small and large vehicles. One thing is for sure, these tires wear out. You need to take some decisions when such things happens. You have to do something with it. In the tire outlets if you go there for buying new tires they generally take those tires off. Sometimes the tires are discarded. They also put them up for sale to people who are just looking for a spare.

When a tire is recycled what actually happens?

Tires can be one of the largest sources of waste. Tire farms dot all the states. These huge lots contain thousands of tires. Most of these tires are of little use. They can be turned into ?crumb?. These product are used mostly as filler.

Most landfills do not want used tires as they take a lot of space. As a result of decomposing waste material ,it can trap large amounts of methane gas. These tires then rise to the surface and become buoyant. Most landfills have liners that keep the contents from damaging the groundwater in the area. Tires actually upset the process.

Now, enterprising companies are starting to find more uses for these tires or the product of them. Ground up tires can also be used as fillers. They can also use this byproduct as a cap on landfills. These tires can be shredded onsite it is the only convenience.

Apart from landfills, Tires are also used in hot melt asphalt. These products are also used in replacing asphalt. Those crumbs are also used in certain kinds of concrete as a filler. Many people use old tires around the home and in the garden. They are used to make flowerbeds. The grindings are used as mulch in gardens.

New processes such as Pyrolysis can used to turn old tires in the fuel gas. The process of devulcanization is used to turn old tires into crumb. Devulcanization is the method commonly used for turning old tires into crumb. Material can also be used for making new tires. That means a reduction in raw material costs.

The process involves heating the tires whole or in shreds, in a huge vessel, in an oxygen free environment. The rubber breaks down into smaller molecules when soft. These smaller molecules vaporize leave the reactor. The vapors can be used as a power source by burning them.

Most of the companies use this process. This is good for the environment and good for companies wanting a good source of this type of fuel.
