Glass is a material that is perfectly suited to recycling. It can be melted and recycled over and over again, without any loss in quality.
Clear and colored glass is collected separately through bottle banks. Clear glass is turned into clear glass again, and colored glass into colored glass. When collecting glass door-to-door, clear glass and colored glass are not separated.
Anything that is not glass is removed automatically or manually by the recycling companies. Impurities such as porcelain, stoneware or heat-resistant glass from hot plates or oven dishes are separated from the recyclable glass.
The recyclable glass is then crushed into shards a few centimeters in size.
These pure glass shards are then put into an oven, where they are melted and then given a new shape and purpose.

Glass can be endlessly recycled. This means that the end products are new bottles, flasks and jars.
Glass is made from a mixture of sand, sodium carbonate – also called soda – and lime. In order to manufacture new glass, temperatures of between 1,500 and 1,600 °C are needed to blend the three ingredients. By using recycled glass we are not just conserving natural resources but also saving energy. Specifically, the glass manufacturing plant requires 25% less energy, and less than half the amount of soda is needed to lower the melting point. As a result, less CO2 is emitted and we contribute to the fight against global warming.
Porcelain, stoneware, terracotta, heat-resistant glass, etc. do not belong in the bottle bank because they cannot be melted in the ovens.
And that is why we are also counting on you. Consult the sorting rules for glass.
