With tougher legislation and tighter environmental controls coming into force, it is time for the window industry to make use of its waste. The "Voluntary Commitment" is the pvc industry's response to the challenge of sustainable development in the first decade of the new millennium. The window frame sector, represented by European Plastics Converters (EuPC), commits to mechanically recycle increasing quantities of pvc window frames at the end of life of this application. The European pvc industry aims to recycle half of the collectable window profile waste by 2005, with a target of 25% by 2003. Spurred on by the EU to set more stringent targets for recycling, 20 leading pvcu window systems companies have pledged their voluntary support.
