Tyre Bales a Revolutionary Use for Old Car Tyres


Advantages of BSI PAS 108 Tyre Bales: A New Sustainable Use for a Problem Waste

A simple act by WRAP should revolutionise the use of tyre bales in civil engineering and landscape applications, sustainably using this material where otherwise resources would be wasted in their disposal.

It will be obvious to our Wastersblog readers that the disposal of vehicle tyres is a real headache, for the waste management industry, and as motorists we are all feeling the pinch from rapidly rising tyre disposal costs.

Certainly, the last time I bought a new tyre, the garage added several pounds to my bill for disposing of the old one.

However, a number of landfill operators have been using tyres for leachate drainage within landfills for some years as an engineering material, and they have found that using tyres as drainage layers in landfills provides adequate flow capabilities, at close to zero cost for their leachate drainage. However, manhandling individual tyres to stack them efficiently on site is a tedious, dirty, and time consuming task, and this fact alone has probably done a great deal to limit tyre use uptake. Whole and granulated tyres have been used for this purpose.

That was for whole tyres, as far as we are aware, just about the only use available in landfills.

Since WRAP published a British Standards Institution (BSI) and has produced a Publicly Available Specification, PAS 108, in collaboration with the tyres reprocessing industry, a whole new range of uses has opened up, from baled tyres.

Almost overnight, baled tyres have become an engineering product with standard bale sizes and shapes, and most important of all, clear design strength data.

Designers and purchasers can now use the structural and drainage characteristics provided from the research done for the PAS, and incorporate tyre bales into designs, just like any other proprietary geo-synthetic material.

In short, providing a specification for producing compact tyre bales of a consistent and verifiable quality and dimension, opens up a new and potentially huge market for waste tyres.

The method re-uses tyres, reducing the demand for the primary aggregate materials used in the past.

The PAS 108 specification can be adopted by suppliers for producing tyre bales such that potential customers will be assured that they are procuring a construction material of consistent and verifiable quality.

Furthermore, the core of this document addresses the production, handling, storage, transport and placement of standardized tyre bales, the dimensions and properties of which are standardised and described in this PAS.
