Recycling of glass

Cost-efficient laminated glass reprocessing

Today, glass is one of the products that surrounds us every day and everywhere. The use of glass is increasingly evolving and so are the quantities of glass waste generated and its recycling. Bottles and ordinary flat glass have already been economically recycled almost everywhere for decades. For some years now, the process of laminated glass recycling has also been developing steadily as the demand for glass and also PVB increases.

Our areas of application at a glance:

  • Laminated glass
  • Safety glass
  • Float glass
  • Automotive glass
  • Container glass
  • Stained glass

Efficient separation of glass from aluminum caps

Maximum glass removal from aluminum-glass composite materials

Aluminum caps from hollow glass present a particular challenge in the recycling process, as they are often tightly bonded with glass residues. The PTRF fine grinding mill has been specifically developed to efficiently and selectively process these composite materials. In this process, the glass is completely ground into a fine powder, while the aluminum caps remain largely intact.

In the subsequent recycling steps, glass residues can be almost entirely removed from the aluminum parts. The result is a pure aluminum fraction and a glass recovery rate of around 30%of which 27% is ultra-fine glass powder (< 1 mm). Smaller glass fractions remain in intermediate streams, which can also be further processed or specifically separated.

This precise separation not only improves the recycling rate but also opens up new economic potential in the processing of complex packaging materials.

Recycling photovoltaic modules

Our recycling solutions for PV modules

Photovoltaic modules are among the most environmentally friendly energy sources. Nevertheless, they are also among the most resource-relevant waste products, which is why the recycling of PV modules is becoming increasingly important. PV modules contain valuable materials such as aluminum, glass and various plastics. As things stand today (2022), more than 95% of these materials can be recycled and we are doing our part.

Shredders

The aim is to tear the film-reinforced panes into small pieces, so that a secondary crusher such as our PTKS impact mill can later separate the film and glass cleanly from each other.
