The Tyre Bale Inspectorate  

PAS 108 represents an environmentally friendly way to dispose of used car tyres which has reached
new heights within the UK. The government  have commissioned this specification for the safe disposal
of this fundamental waste product.

However, landfill operators have been using tyres for leachate drainage within landfills for some years
as an engineering material and were able to see that using tyres as drainage layers in landfills provides
adequate flow capabilities, at close to zero cost. However, manhandling individual tyres to stack them
efficiently on site is a tedious dirty and time consuming task, and has probably limited tyre use uptake.

That was, as far as we are aware, just about the only use available for whole tyres. However, now that
WRAP has commissioned the British Standards Institution (BSI) who have prepared the Publicly
Available Specification, PAS 108, in collaboration with the tyres reprocessing industry, a whole new
range of uses has opened up.

The secret is that designers and purchasers can now use the structural and drainage characteristics
researched by these bodies, and incorporate them 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 large market.

The compression of these tyres into bales provides a means of reusing these tyres whilst at the same time,
reducing the demand for primary aggregate materials in construction. PAS 108 provides a specification that
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.

This is where we come in! Since the government have commissioned this PAS108 document to control the
production of a useful aggregate from a waste product, we at PAS 108 Limited have commissioned this
PAS108 document to control the production of a useful aggregate from a waste product, we are the leading
and most engaged independent inspectorate of the satisfactory production of this product. 

PAS108 requires that ten in every one thousand bales are tested and the results recorded in a identifiable
manner in order that each bale produced can be monitored and located to it’s end use destination. 
Dependant on each production sites volume of production, PAS 108 Limited  can be appointed to attend
each manufacturing site on a regular basis and carry out these required test’s.  The results are made
available not only for the appointing authority but also for the individual manufacturing site, the end user,
civil engineering or landfill management organisations and also the Environment Agency to
demonstrate that the site is regularly complying with the basis of the licences issued. 

This opportunity provides all involved with piece of mind that the this waste product is turned into a useful asset
and is strictly and consistently compliant to the current requirements set out by WRAP in the PAS108 document.

In addition, our company is able to offer advice on Health and Safety issues especially considering the
non-skilled requirements for the operation of such a baler.  We also offer to liaise with the Environment Agency
on behalf of production sites - to ensure the continued compliance with the EA licences issued and ensure the
conditions are upheld. 

Many of our clients find our services to be invaluable and also use us to find links to end users of the manufactured
product to assist in the building of their businesses.

The core of the PAS108 document addresses the production, handling, storage, transport and placement of
standardised tyre bales, the dimensions and properties of which are standardised whilst providing for variance and
tolerances within controlled boundaries. One of the big gains in producing a fully compliant bale lies in the guidance
that is given on engineering properties and typical construction applications. WRAP, if you have not already heard, is
the organisation established by the UK government in 2000, as a not-for-profit company with government funding from
England, Scotland, Wales and Northern Ireland, to oversee projects of this type across the country.

As a result we think that these bales will prove to be incredibly versatile, easy to use and practical, for all sorts
of applications in Civil Engineering (road building, river and coastal defences), and also as rapidly erected walls
and wonderfully effective sound attenuation screening. We have developed relationships with leading engineers in
varying construction and drainage fields for the purpose of identifying practical and efficient uses.

We have summarised a selection of suggested uses below:

Tyre bales produce no short-term leachate nor other emissions and are extremely slowly biodegradable.
The Environment Agency is said to have put on record that tyres do not decompose!

Tyre blocks will last for many years and even once deployed for one task they can easily be
re-deployed, years later, to another completely different role.

Tyre bales have already been used in River Flood Defence Schemes and bulk bale stacking has both
replaced shingle at Pevensey Beach Flood Defence Scheme and provided a much more robust defence
than just shingle - if storm damage ever erodes the top away !
