How To Benefit From Recycling Tyres Into Transportable Materials

How to Benefit from Recycling Tyres into Transportable Materials

Tyre waste in Australia grows on average by 459,000 tonnes a year. 70% of that waste is recovered and used across the world. The remaining 30% is either piled into landfill or dumped(1). This pollution greatly damages the environment, due to the tyres’ inability to decompose. In their dumping grounds, exposure to the sun releases chemicals from the tyre into the air, water and as well the ground. This kills beneficial bacteria in the soil, which is catastrophic to plant and animal life.

Some turn to burning tyres as a method of disposal, which is incredibly irresponsible, given that toxic black smoke pours into the atmosphere in this process. Tyres on fire also cannot be extinguished by water, and those who try doing this only spread the tyre’s chemicals, which often wash into waterways(2).

To avoid coastal reserves from becoming tyre junkyards(3), or if you think financially, avoiding ten-of-thousands of dollars in fines for being caught illegally dumping(4), then tyre recycling will be appreciated by both the environment and your wallet.


Tyre Recycling Machines and Partnership with TSA

Waste Initiatives has been providing tyre recyclers to large and small businesses for over forty years. Our machinery completes the tyre recycling process from shredding tyres into chips, through to grounding remaining material into a sellable powder. In fact, throughout the tyre recycling process, different types of the broken-down primarily rubber material can be sold for a profit. 

Our expert team advises customers both on which tyre recyclers are suitable for the size of their business, as well at which point in the tyre recycling process would return them the best profits, based on their waste output. Waste Initiatives has also partnered with Tyre Stewardship Australia, to support their founding purpose, which is to source sustainable outcomes for end-of-life tyres and eventually influence a circular tyre recycling economy in which tyres are completely removed from the waste stream(5).

Continue reading on to learn more about the different phases within the tyre recycling process as illustrated below, and how these machines convert tyre waste into different outputs of rubber material – which may be valuable for your business to sell as a product.

TDF – Tyre Derived Fuel: Eliminating Large Tyre Waste Through Shredding

The first phase of tyre recycling is shredding end-of-life tyres from passenger, off-road and large-vehicles into tyre derived fuel (TDF). This recycled fuel source is a much greener alternative to fossil fuels and is also favoured for its energy potential. For example, the heating potential for average sized passenger tyres is comparingly higher than coal by nearly 7,000 Btu/kg(6).

TDF’s efficiency in generating heat is even more attractive to industries when considering this fuel is significantly cheaper than fossil fuels. That’s because mined resources are continuously being hit with new taxes and regulations due to the environmental damage caused in its sourcing, transporting and burning(7). 

If your business has a tyre waste problem and would benefit from using a derived fuel as a burning source, then look across the WasteQuip shredder series provided by Waste Initiatives. These tyre recyclers range from 1 to 4 shaft shredders and have unique functions/accessories tailored to reducing tyre waste and producing TDF.


Tyre Crumb: Converting Strips of Rubber Into a Granular Material

Following TDF in the tyre recycling process, is the tyre crumb phase. This is the phase in which tyre recyclers process the ‘chips’ of rubber from the shredders into crumb rubber. These tyre recyclers do this, by separating rubber from the textile and steel materials, in-turn producing high-quality rubber crumb granules varying between 1 to 4 millimetres in length.

This material is a particularly valued tyre recycling produced commodity given its use in the construction of surfaces for sporting venues and parks. Drive past a modern playground, and there’s a good chance that the brightly-coloured floor is a soft-fall rubber surface designed to protect children in play. Likewise, many great athletic tracks utilise the material to reduce the chance of runners experiencing sprains and other serious foot/leg injuries.

Its value to the environment should also not be overlooked, given it has been proven that over a 70% reduction in CO2 emissions is achievable when using these tyre recyclers(8), opposed to leaving tyres in landfill or burning them which again releases harmful toxins.


Tyre Powder: Producing Highly-Saleable Rubber Powder

The final stage in the tyre recycling process available for businesses to consider as a method of waste reduction, are tyre recyclers converting the rubber crumb into powder. Rubber powder has many uses, including its potential to enter the tyre recycling process again by being converted into new tyre compounds. Additionally, seals, insulation panels and shock plates can also be created. 

Rubber powder is also valued by road builders for its count of antioxidants, as when mixed with other road-building materials, the rubber reduces the ageing process of the surface and reduces noise when driven on.

Low-end products are also producible from this tyre recycling product, such as fenders and damping materials.
