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.

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.
