This is how it works
- Separate collection
You can put glass bottles and jars in the bottle banks, underground containers or sorting streets in your town, city or commune. In some regions glass is collected house to house.
It is important for the recycling process that clear and coloured glass are separated. After all, clear glass is recycled into clear glass and coloured glass is again coloured. So in most cases, separate bottle banks or containers are provided or they have two separate compartments. The lorries that fetch the glass also have a separating wall. In the recycling company, the lorry unloads its contents in two piles: clear glass on one side and coloured on the other.
Only when glass is collected house to house, which is the case in a limited number of towns, cities and communes, no distinction is made between clear and coloured glass.
First, the largest impurities are removed, with a specific focus on heat-resistant glass, pottery, stone and porcelain, as these can seriously disrupt the recycling process. The glass is then broken into shards automatically using various techniques. The size of these shards corresponds to the required end quality. Metals are removed using magnets and eddy current separators. All recycling companies are equipped with advanced optical systems that remove further impurities and can even separate the glass on the basis of colour if it has not been collected separately.
The clean glass shards, also known as furnace-ready glass, are melted and reshaped to take on a new life as a bottle or jar.
Glass can be endlessly recycled. So the end products are again bottles, containers and jars.
