Globally, waste disposal is an increasing problem. Dump sites are filling up at an alarming pace which causes a variety of space, health and environmental problems. A large portion of the junk going into dumps is made up of used tires and this is a major concern. pyrolysis process of continuous waste tire pyrolysis plant (pirolisis de neumaticos) offers a potential strategy for managing this problem.
Over the last hundred years or so automobiles, and heavy vehicles like trucks, have gone from a rare sight to something that most of us encounter on a daily basis. In the developed world most households own at least one car and they are even commonly to be seen in developing nations. These vehicles are all fitted with tires and to keep up with this demand vast amounts of tires are manufactured.
On a worldwide scale approximately two million tires are manufactured every day. Cars, bicycles, and commercial vehicles all make use of some type of tire. The nature of their function meant that tires are subject to a lot of wear and tear, causing new tires to have to be fitted to a vehicle on a regular basis and the old tires dumped.
The main raw material used in the manufacture of tires is synthetic rubber that is derived from petroleum, also called crude oil in some places. Synthetic rubber is not biodegradable and untreated tires could easily take more than a hundred years to decay in a land fill. To make matters worse some people just dump their used tires in public places and they are a common site in many rivers, lakes and fields.
Landfills are a big problem in densely populated areas as they take up a lot of valuable and limited space and can cause health and environmental problems like air and water pollution. It makes sense to reduce the amount of junk going into these landfills as much as possible. Recycling is a very good way to limit the amount of waste that has to be dumped into landfills.
Tires can’t easily be recycled in their original state. Sometimes they are shredded or broken up into beads or chippings. These derivative products are used in the manufacture of certain products like rubber matting, running tracks and other sports surfaces.
In principle this kind of recycling makes sense however it is often impractical due to the substantial costs that must be incurred in order to gather up and process waste tires. As a result of all the input costs recycled materials are often very expensive. This stops them from being truly attractive to manufacturers.
A possible better solution for recycling used tires is pyrolysis process of continuous waste tyre pyrolysis plant. This process subjects old tires to high heat in and oxygen starved environment. As a result the tire material breaks down into gas, oils and carbon char. Usable products, like carbon black for example, can be extracted and re-used in the manufacture of other products.
