Recycled windows: New PVC windows with a high proportion of recycled PVC (rPVC)
PVC windows are stated to have a service life of up to 50 years or more. The service life of building components is set out in the table ‘service life of building components’ published by the BBSR. Instead of being disposed of, they can be dismantled, collected, sorted by material – such as PVC, glass and metal, etc. – and the PVC can then be recycled.The recycled PVC (rPVC) obtained is then reused in the core of new window profiles. This closes the circle.
Promotion of PVC window profiles with high rPVC content
According to industry figures available to us, standard profiles contain around 40 per cent recycled material. Today it is possible to produce PVC profiles with a higher rPVC content. However, these are custom-made products. As part of the municipal support program "Climate-friendly living and working in Düsseldorf", the RAL Quality Association has established evaluation criteria and a verification procedure in cooperation with the city of Düsseldorf. It enables indow manufacturer and window buyer to select the right profiles. You can find information on the recycling scheme and recycling options at www.rewindo.de.
