Tire recycling, also known as rubber recycling, refers to the process of recycling used vehicle tires that can no longer be used on the vehicles due to wear and tear or irreparable damage. Used tires are among the most problematic and challenging sources of solid waste.
This involves the processing of waste tires for reuse. Typically, this category of tires, also known as end-of-life tires, are no longer functional. And this is due to damage and wear.
Tire recycling then involves the conversion of waste tires into materials that we can use to create new products. why do we need to recycle tires?
Well, this is due to their increasing numbers and how fast some tires reach their end-of-life. In turn, this means that more tires are getting into landfills. when we talk about landfills, we are discussing more pressing issues.
We are worried about environmental pollution, threats to marine life, global warming, and many more issues that arise from landfills. So, to avoid these, it seems like a good idea to recycle.
Every year, over one billion scrap tires get generated. And the only way to get things done the right way is through recycling.
In fact, history shows that recycling tires have always been a smart move. For instance, a couple of decades back many people did not own an automobile vehicle. Yet, piles of waste tires were over one billion globally.
However, as of today, when many people already owned one automobile or the other, the pile of waste globally contained only about 60 million scrap tires. And this is thanks to tire recycling. So, yes, tire recycling is a good choice; it has always been.
Here is a step-by-step guide that shows you how
The collection of Waste Tires is the first step in any recycling process. At this stage, individuals and businesses dealing in tire recycling collect tires.
The first step after taking waste tires to processing plants is to cut them into small pieces. The idea here is to reduce the tire’s size into a material that one can handle easily.
With the help of tire shredders, tires are shred or cut them using the rotating shafts. Eventually, this stage produces pieces of tire shreds of 2-inch length. At the end of this stage, you then derive raw materials that you can use for fuel.
Tire processing take through mechanical systems involving scraping scrap tires into smaller chips. Typically, you place the rubber shreds into a granulator with screens to track the size the shred gets reduced to.
You will then proceed to remove steel using strong magnets. Also, there is a need to separate the fiber from other constituents using air classifiers. Once you do this, you will have obtained recycled rubber that is clean and ready for other products.
Here, you process and prepare tired shreds for elimination and separate tire wires from rubbers. This step involves the separation of fiber and screening.
Steel wires, which give resilience and strength to tires, get removed and recycled.
The stage after separating wires from rubber is screening. The gist here is to carefully observe the rubber and ensure no wire is left in the rubber. You will essentially screen large volumes and sizes of rubbers with no wires and sort them according to their sizes.
It also involves the elimination of any unwanted substances and reducing the sizes of large rubbers and unwanted leftover pieces.
The cleaning stage is the penultimate stage. This involves a thorough cleaning of the screened rubber. Here, you use water and cleaning agents in a thorough cleaning process.
This marks the final stage of recycling tires. The clean rubber derived from the cleaning staged gets packaged. It then gets delivered to factories that need them as raw materials for production in their respective processing plants.
Production Process for Shredded Tyres – 1 inch.
At this stage, whole tyres are fed into Super Shredder/ Primary Shredder, which reduces the whole tyres into variable size strips.
At this stage, primary tyre shreds are fed into secondary shredder unit with cutting chamber through the outside shaft system/ conveyer system, which produces tyre chips of size up to 20mm. During this process, a substantial portion of the Fabric and Steel from the material is extruded using magnetic separation process.
The shredded products are categorized under various size ranges, in line with the factory machinery capacity. Rubber Chips are shredded and granulated from tyres. They are pure rubber free from textile and steel (upto 96%). They have a wide range of application as a product because it is used in other rubber products to shape and build them. They have a downstream conversion product. Rubber products are made 100% of rubber chips. They are free of any hazardous substances and have been put through laboratory tests to assure quality & safety to users.
