The renovation of residential buildings is an important step when it comes to energy savings and climate protection. A recent example of such renovation work is the modernisation of eight blocks of flats, each containing 194 flats, in the „Bissierstrasse“ street in the Betzenhausen district of the German city of Freiburg. During this modernisation, a total of 1500 old PVC windows will be replaced with new heat-insulating PVC windows within a period of 80 days. The scrap windows will then be processed using mechanical recycling as part of the collection system operated throughout Germany by the window recycling system of Rewindo Fenster-Recycling-Service GmbH in the German city of Bonn, with the raw material recovered in this recycling process being made available for reuse in the production of new window and building profiles.
According to Gerald Feigenbutz, the Managing Director of the European PVC Window Profile and Related Building Products Association (EPPA), this major recycling project is a „beacon“ that acts as additional proof that closed loop recycling management is functioning well in Europe and provides a number of benefits for all parties involved.
Both the current recycling project in Freiburg and Europe’s largest recycling project involving 2500 scrap PVC windows in the German city of Norderstedt near Hamburg are being supported by Rewindo and EPPA. Over the past few years, AGPU has combined forces with Rewindo to organise the German „Environmentally Friendly Modernisation“ competition. The two current projects mentioned above and this competition are important examples that demonstrate the successful use of PVC recycling. It is essential that this success is constantly made clear to decision-makers in the world of politics and in public authorities in order to further increase the acceptance of PVC recycling activities.
