Dear Readers,

This is the fifth article from our monthly blog series “Weibold! Academy”.Weiboold Academy Logo

With these articles we wish to provide our readers and our newsletter subscribers 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, after that we covered the Tyre Recycling Value Chain. Last month we started describing the various applications for all kinds of output a tire recycling plant is generating and we covered the Whole Tires & Tire Shreds Applications in General and now we continue with rubber granulate applications.

Rubber Granulate Applications

Noise Barriers

A variety of noise barriers are fabricated from used tires. The majority of designs utilize cut tires; some mix the tires with other waste products such as old railroad ties, worn skis, dairy containers, etc. In some an armature is built of ties and skis, halved tires are attached and filled with soil and compost then planted with greenery and vines. They have proven to be successful sound absorbers and to significantly reduce noise along highways and high speed train tracks.

Trains and Trams

Recent research and developments with recycled rubber granulates haven led to several new products which can be utilized on both train and tram tracks. Each has the capacity of reducing both the noise and the vibrations which emanate from the vehicles. Tests results indicate that noise can be reduced up to +40%, while vibrations can be limited up to +30%, making their use a good investment particularly in heavily populated city centers and along high speed train routes.

Road Furniture and Signposting

Road furniture, such as speed bumps, speed strip-ping and bollards constitute a relatively new development in the use of rubber granulate in civil engineering projects. Also added to the list are weighted sign supports which are being used at railroad crossings and on motorways. Expansion joints on bridges and motorways are also an important new use. 

Outdoor Sports Surfaces

Recent developments in mixing granulated rubber with a broad variety of elastomers and polymers have produced a new generation of all-whether sports playing surfaces. These surfaces have the added benefit of reducing severity of injuries sustained in play due to their resiliency. The surfaces are easily installed and inexpensive to maintain.

Paving Blocks

A range of new paving materials has been developed from tire granulate. Easy to install, skid proof, water resistant, mold and mildew proof, resilient and easily maintained, these paving materials are used for patios, pool areas, and garden paths, among other public and private applications. Available in many colors, textures and shapes, they are an inexpensive alternative to more costly, slate or molded pavers. Many systems can be placed directly on soil without the need for costly pre-installation preparation.

Indoor Sports Surfaces

Wooden gymnasium floors are rapidly being replaced by a composite made from recycled automobile and truck tires. Easy to install and inexpensive to maintain, these products are used in schools as well as in commercial arenas. The material does not interfere with the game play and offers players a more resilient surface. It has also been shown to reduce the severity of injuries sustained in accidents. An added benefit is the accompanying reduction of noise which often makes indoor competitions difficult for spectators. In common areas, e.g., entries, dressing rooms, etc., it does not stain nor is it harmed by spilled liquids.

Interior Floor Coverings

Recycled rubber has been used for many years in the manufacture o floor tiles, carpet backings and underlays. Many commercial and industrial sites, health and research facilities utilize flooring made from recycled rubber because of their characteristics of limiting sound penetration, resiliency, water proofing, and resistance to solvents, acids, oil, etc., low maintenance costs and long life. New uses include pedestrian and seating areas as well as entries at airports and railway stations.

Playground Equipment

Many different types of playground equipment contain recycled materials, including rubber. Several new items are being produced for playgrounds, primarily because of their safety and low maintenance characteristics. Among the newest products are child-size trampolines which incorporate rubber in the mat, rim and feet. Portable hopscotch mats are popular for temporary and multiple use sites because they can be easily stored when not in use. Slides made from recycled composites are more colorful and easier on little bottoms.

Insulation and Sound Absorption

Granulate is being used as an insulating material in different forms of construction for both residential and commercial structures. Granulate is processed into continuous rolls of flexible material. The material is cut to size and secured between other materials, forming a sandwich. Concrete blocks often form the base. Once bonded together, the unit is covered with an appropriate external surface. The structure offers both thermal and acoustical insulation.

Studies show that well cared for cattle produce larger quantities of better quality beef or dairy. Cattle mattresses provide a high level of comfort while easy to maintain. An outer envelope is made from non-toxic, waterproof material used for military or maritime activities. A second inner envelope is filled with granulate. The mattress can be used in fully or partially sheltered areas. It can be places directly on the stable floor, on a concrete slab or in specially constructed frames.
