Of the 3,500,000 tonnes of tyres that arise each year in EU, more than one-third is recycled through a variety of material treatments. In addition to granulate and powders, tyre recycling treatments yield large quantities of steel and textile fibre residues, contributing up to 22% and 5% respectively to the weight of a new tyre. Textile residues from efficient recycling system can correspond to 10% in weight of the input (used tyre).
In an average efficient plant the quantity of textile residue could amount up to 20% in weight on the input, owing to the retained rubber particles. Until recently, these residues were landfilled or incinerated. Recent research demonstrated that these textile residues can be used to produce insulation product with considerable noise, thermal and vibration dampening characteristics.
The challenge is delivered from insuleco to the other partner like the one we discuss in the center of the meeting at last event that was held in roma during the last summer, the aim of the event was the lunch of the start up.
The revised Framework Directive on Waste (2008/98/EC), has been a major driver over the past decade for the development of waste management policies at the national level.

The INSUL-ECO project offers an economic, productive and eco-innovative solution, at European level, to the problem of fibre disposal through combustion at a cost to the tyre processor by proposing a new product and a production process. The alternative proposed solution is easily replicable around Europe and the tyre-derived fibres can find many potential applications and provide a source of income for tyre processors.Moreover, the availability of recycled and efficient thermal insulating panels, such as the INSUL-ECO panels, addresses the European legislation on energy efficiency, which aims at:
– reducing the primary energy demand of buildings for cooling and heating
– renovating, for the next 40 years, an estimated 3% of the buildings in Europe per year (new buildings generally need less than three to five litres of heating oil per square meter per year, older buildings consume about 25 litres on average.)
The potential market of INSUL-ECO panels consists of both thermal insulation panels and acoustic insulation panels for the new construction and renovation of buildings. The full capacity of the INSUL-ECO line, developed under this project, would hardly account for less than 0,01% of the whole European market. The performance of the panel is rather equivalent to those of other conventional panels; and the resistance and durability of the product are even better.
The legislative framework in the EU in general, and in Italy and Spain in particular, is especially favourable on one hand to the recycling of ELTs and, on the other, to insulating solutions for the building market. Moreover, the use of recycled materials in construction is strongly encouraged.
The legislative framework
Directive 2002/91/EC on the energy performance of buildings (EPBD) introducing the concept of “energetic efficiency certificate” that new and old construction must fulfil, addressing the market towards more efficient insulating solutions of buildings.
