With High 5 in Antwerp, Belgium, SUEZ has revolutionised glass recycling. As a pioneer in glass recovery in Europe, High 5 is the first plant in the world capable of separating incoming glass into four distinct qualities: colourless, green, amber and "dead leaf".
For glass makers, a secondary raw material of exceptional quality
A battery of latest-generation optical sorting machines purifies and separates broken glass according to their colour:
- it purifies broken glass and eliminates the infusible residues unsuitable for glass production (crystal, stone, porcelain, vitro-ceramic);
- broken glass is finely sorted by colour for high-quality granulate;
- the fineness of optical sorting enables the creation of a new colour of granulate, dead leaf, highly appreciated by glass makers.
The properties of the granulate produced by High 5 enable a significantly higher proportion of recycled glass in the production of glass packaging.
Substantial savings, preserved natural mineral resources
- Glass sorting by colour done by High 5 simplifies not only glass recycling but also its collection by municipal authorities, which is done by separate colours in most European countries.
- The granulate produced by the plant enables glass makers to reduce the number of transformation phases required, consumes fewer natural mineral resources and less energy.
