Glass - a gift from nature

Glass pearls are said to have existed as early as the middle of the 3rd millennium BC. The first known recipe for glass comes from the library of the Assyrian King Ashurbanipal (approx. 659 BC): 'Take 60 parts of sand, 180 parts of ashes from seaweed and 5 parts of chalk and you get glass.'

A material with such a long tradition deserves to be treated with special appreciation and care. Recycling is the least we can do! Glassmakers love glass and ensure that old glass is repeatedly formed into new, healthy quality packaging: jam jars, pickle jars, wine bottles, juice bottles, bottles for vinegar or oil, perfume bottles - top quality is guaranteed.

Three Austrian glassworks recycle glass packaging: Vetropack Austria GmbH in Pöchlarn / Lower Austria and Kremsmünster / Upper Austria and Stölzle Oberglas GmbH in Köflach / Styria.

Step 3: Old glass is carefully prepared for recycling

The waste glass is processed in the glassworks, which means:

  1. Step:
    The waste glass with foreign substances is sorted by conveyor belt, separated into colored and white glass.
  2. Step:
    Foreign matter containing iron is captured by a magnetic separator and sorted out immediately.
  3. Step:
    All larger foreign substances are sorted out by hand along the conveyor belts.
    Used glass is carefully prepared for recycling
  4. Step:
    In the so-called "crusher", the old glass is crushed to the size (15 mm) required for the melting process.
  5. Step:
    The crushed old glass is sifted on a perforated sieve channel. Fine-grain waste glass falls through the sieve and then moves directly to the second magnetic separator. Foreign matter that is lighter than glass is sucked off in front of the perforated screen.
  6. Step:
    The screened old glass is precisely x-rayed. Opaque foreign substances such as ceramics or aluminum are optically recognized and eliminated.
  7. Step:
    Manual re-sorting.
  8. Step:
    Remaining iron-containing substances are removed from the shredded waste glass with another magnetic separator.
  9. Step:
    At a final control station, the old glass is checked again.
  10. Step:
    The recycled glass can now be used as a secondary raw material for the production of glass packaging.
  11. Step:
    The sorted out foreign matter is either recycled or disposed of. The majority of the foreign matter is earthenware, ceramic or porcelain.
