Closed loop aluminium recycling – why? The recycling system begins once parts are dismantled. As a member of A|U|F, you save resources, economize in the long term and qualify for tendering.
Who are the partners? More than 200 recycling companies, systems houses, metalworking companies and architectural and planning firms have registered to be A|U|F environmental partners and collect aluminum.
How good is recycled aluminum? A process developed by A|U|F is used to separate the different types of aluminum collected and shred them. The quality of the resulting secondary aluminum is identical to that of primary aluminum.
What are the benefits? New extrusion billets are produced in plants for semi-finished products. The process only requires 5% of the amount of energy required to make primary aluminum.
How does the market benefit? The extrusion billets are made into new profiles for windows, doors and façades. This way, the material remains in the EU. Without the closed loop recycling system, the EU market loses more than 500,000 tons of recyclable aluminum every year.

About A|U|F and its mission

A|U|F was founded in 1994 and reactivated in 2010 as a registered association under German law. Sponsored by metalworking companies, systems houses and other companies, A|U|F organizes a closed loop system for recycling aluminum used in windows, doors and façades.
