Like everything else, tires also have a certain amount of life. After becoming old and worn out, they become irreparable, and many people dump them in landfills. Unfortunately, such types result in various environmental problems.
As such, there are efforts to minimize tire piles in landfills. And due to that, most people reuse waste tires for many other purposes. Regardless of other uses, the best thing to do is put them in the scrap tire recycling system.
About Tire Recycling
By tire recycling, we mean the process of recycling waste/end-of-life tires (ELT) that are not acceptable to use as an outcome of irreparable wear or damage. Tire recycling technology and systems are necessary for such a process.
Further, we will look into the scrap tire recycling system process and why it is necessary for the environment.
Systems To Recycle Used Tires
There are many recycling processes for recycling tire waste. It is possible to recycle tires into steel, and rubber wires are reused or recycled through the tire pyrolysis system and further become fuel
Removing Steel Wire
Tires gain resistance with the help of steel wires, which are removed before the tire recycling process starts. There are many resues for the steel wires in steel goods. The tire rubber is further processed in the phase of the recycling system.
Processing of the Whole Tire
After you remove the wires, you should reduce the rubber tires in size. Two ways are there to minimize tire size:
Cryogenic: Recyclers use liquid nitrogen to freeze tires. Then a hammer mill smashes them into small pieces. Then a high-power magnet removes the leftover steel pieces, and an air classifier removes the small leftovers.
Metal: Here, a shredder machine is used that shreds down the tire rubber into tiny pieces. A granulator is used to provide size to these pieces.
Now recyclers have screened the rubber and removed steel and fibres that impact the rubber’s usability. They also sort rubbers by their particle size in the screening method and remove the larger pieces.
The tire recycling method is pyrolysis, whereby recyclers heat the shredded or whole tires in an oxygen-free reactor. Later, they soften the rubber, and the polymers break into small molecules. The molecules then take a gaseous form and get out of the reactor.
These gases are directly burned to make power or condense into fluids further used as fuel. Then the systems reduce some molecules, and the smaller ones are used as fuel. It is not possible to use all tire components as fuel. After the pyrolysis tire recycling system, only around 40% ( by their weight) of these tires are taken out as ashes.
Now the screened rubber is cleaned with water or other cleaning materials. Now the rubber is also used as a raw material. Some examples of rubber use are playground turfs and rubber shoes.
Other examples of scrap tire disposal recycling systems recycling A/S and other eco equipment. The primary resource of recycled tires is fuel. Still, these are processed into other products like industrial feedstock, construction materials, tire-derived aggregate, crumb rubber, and ground for the rubberized asphalt, etc. Tire recycling systems are of significant importance as the need for new sustainable, circular end-use markets.
