Dear Readers,

Weiboold Academy LogoThis is the fourth article from our monthly blog series, called “Weibold! Academy”.

The idea behind these articles is to provide our readers and our newsletter subscribers with valuable knowledge about the tire recycling industry.

We started our educational series with the basics and month by month we will together dwell deeper into the world of tires and the ways of recycling them.

We believe that a good knowledge foundation might be beneficial for everyone involved in the industry and each month we will cover different topics, thus providing you with important know-how for the tire recycling industry.

In the second article from our series we started explaining about the recycled rubber output spectrum and we also started covering the topic about Rubber Granulates.

The third article explained about Rubber Granulates, Rubber Powder, Tire Derived Steel and Tire Derived Fiber.

In the last part we covered the Tyre Recycling Value Chain.

With this month’s article we start describing the various applications for all kinds of output a tire recycling plant is generating.

In this and the upcoming articles we will include information on whole tires, shreds, granulates, steel and tire derived fiber for the sake of completeness.

Whole Tires & Tire Shreds Applications in General

Retreaded Tires

retreaded tiresRetreaded passenger car and truck tires are the first link in the recycling chain. Every airline uses retreaded tires. Public and private transport companies rely on retreaded truck tires because of their durability, safety, and cost effectiveness. Many local authorities use retreaded tires on municipal vans/buses to transport students, teams, social groups, and the public, as well as on administrative cars, delivery and collection trucks, etc. Municipal use of retreaded tires provides a viable local model of sustainable development. However this model became under threat from cheap Chinese tyre imports in the past years.

Harbors and Marinas

A new system of support structures is also being used for moorings and docks. Pilings are created with cement filled tires sunk into the seabed. No preparatory work is required before installation or heavy construction involved to complete these structures.

Civil Engineering

mountain regions

Whole and cut tires are used in a variety of ways to reinforce and stabilize rock outcroppings and porous dry soil in arid mountainous regions. The tires prevent rock slides and help to limit erosion. In inaccessible arid areas, tires are filled with soil and composting materials, often contain rubber granulate, and planted with hardly seedlings to provide green space in otherwise barren areas. Cut tires also used to channel mountain streams and heavy rains.

Whole tires are also used to create secure landfills. Tires can be used to prepare the base, stabilize the sloping walls, protect piping, and to provide a protective wall around central evacuation pipes and preferential channels for improved hydraulic flow and in the drainage systems for leachate and biogas.

Golf Courses

Golf courses are becoming large users of worn tires, in a variety of forms. Whole tires are used as part of new type of irrigation system in which the tires are buried and serve as reservoirs. In another system, cut tires channel water between a series of catch basins. Rubber granulate bonded with polyurethane and molded to rubber bricks is also used for heavily trafficked pathways.

Tire Derived Fuel

Tires are used as supplemental fuel in cement kilns, paper and pulp mills, among others, as well as in electricity generating plants for public consumption. Tire derived fuel (TDF) is an important alternative means of disposing of tire stockpiles.

Roadway Filter Drains

A new product made of bitumen bound shredded and/or chopped tires is being used instead of the conventional stone or gravel drainage as a topping to roadway filter drains. The application is especially successful in areas where there is a high risk of vehicle overruns such as slip roads. It is cost-effective to install and can considerably reduce highway maintenance costs.

Coastal Defense

The tires are stacked and either filled with aggregate, and/or cement, or piled on concrete pillars in order to keep them in place. The tires absorb the constant energy from the rumbling wave movement, thus reducing the impact upon the fragile shoreline. Of course one can question the aesthetic aspects of this application.

Construction Bales

Bales are used above and below ground for civil engineering and conversation applications including the construction of breakwaters and dams; river and stream banks, road sub-base, etc. They are often used as an alternative to conventional materials in unstable conditions.

Erosion Control

Tire Bales are often the construction units utilized to rehabilitate coastlines that are being eroded by constant wave motion. The bales are used to create simple engineering structures along tidal or fluvial shorelines. They are placed so that they can absorb the pounding energy from the moving water to reduce its impact on the shoreline. When used in public areas, the structures are often covered with other materials such as concrete or planted with local vegetation.

Horse Riding Tracks and Arenas


Shred and chips are being used to construct horse racing tracks, riding rings and jumping grounds. The material was selected not only because it is cost effective but because it provides a predictable surface for the horses´ hooves. It also reduces the number and severity of strain injuries when the animals are at trotting speed or landing from a jump.

Lightweight Fill

Shred and chips are used in numerous civil engineering applications as primary alternatives to more traditional materials such as expanded clay LECA and quarried aggregates. They are used to lighten embankment loads and bridge abutments as well as to prevent uneven settlements in roads and street structures. The smaller particle size of chips adds to the bearing capacity but also to the weight of the overall construction.
