For many of us, recycling is something a little abstract: you rarely see the result of the efforts being done to recycle materials.
With the process of recovery of production waste that we put in place for more than a year, we can provide a concrete example of recycling PSE (expanded polystyrene).
The PSE has beedn used to make boards for a long time now. NOTOX chose the PSE for the greenOne® constructions because of its excellent mechanical qualities and outstanding recyclability rate: 100%!
To shape a standard PSE foam, you need a block of 3.5 kg (180cm x 60cm x 13cm: to get a “shaped blank” of 1 kg and generate 2.5 kg of falling PSE (per board). in addition, the PSE is particularly large (25 kg/m3), and the storage of the wastes quickly becomes overwhelming!
In 2010, NOTOX collected 600kg of falling PSE representing a volume of about 25m3.
To make the best of these waste, NOTOX and Bil Ta Garbi (local union specialized in waste management) have set up a voluntary collection action. The PSE collected is given for free to the company KNAUF (labelizedUni’vert PSE) that is used as a raw material at its plant in Casteljaloux (47).
