The RESOLE Project was launched in 2011 to find materials for making footwear soles with the greatest rubber content possible. A minimum of 50% was set as the initial target.

For the project, SIGNUS has signed an agreement with a firm specialising in sustainable fashion and has the support of the La Rioja Footwear Technology Centre (CTCR).

The work consisted of creating different mixes and performing conventional footwear-industry verification tests on mixes containing substantial amounts of rubber from end of life tyres.

The good results obtained in the flexion tests offer hope for a successful completion of the project.

In October 2011 SIGNUS and a consortium of companies consisting of ACCIONA, ERF, CIDAUT and the Highways Department of the Madrid regional government received support from LIFE+ for a project to develop crash impact barriers using materials from end of life tyres.

The project will run until the end of 2014 and aims to develop two New Jersey crash barriers using recycled materials. One is being developed directly by SIGNUS.

In order to lower the production costs of different regular-shaped rubber pieces compared to current production systems, SIGNUS is developing a project to study the technical feasibility of tyre granulate processing using thermostable resins.

An agreement has been reached with a specialist research centre which has the capacity and appropriate technology to undertake the study for the project.

The work began with a study of the literature and of patents related to the subject matter of the project and it was discovered that no equivalent process exists on the market.

During the implementation of this project, numerous experiments have been conducted to verify the behaviour of the rubber in the process, particularly once it has been mixed with the resins, which need to be formulated appropriately to ensure their suitability.

The tests conducted with laboratory equipment offer grounds for optimism that the project aim will be achieved, although there are many variables that need to be considered before feasibility can be confirmed.



The objectives of this project are to develop a high-performance and less expensive alternative to current horse arenas using materials from end of life tyres.

The design of a horse arena is crucial to the wellbeing of the horses and certain types of arena footing can cause injuries and illness to the horses. The desirable properties of a footing are a certain degree of elasticity and impact absorption, good drainage and simple and inexpensive upkeep. All these properties can be achieved using ELT materials.

Although not widely used in Spain, materials from end of life tyres are commonly found in horse arenas in countries such as France, Britain and the United States. In most cases the ELT granulate is spread in large amounts on the surface of the arena, mixed with sand or some other material.
