Abstract Scope As a result of increasing demands of aluminum in numerous sectors like construction, automotive, transportation etc., the consumption rate has been sharply rising since decades. Aluminum is also used for many different consumer goods such as food storage materials, drink cans, etc. due to its good formability, density and corrosion resistance. This usage in everyday life leads continuously to new types of scraps such as coffee capsules opening the question of their recyclability due to their multi-component structures. An efficient aluminum recovery in terms of high quality and efficiency is essential with respect to reducing the environmental impact and economic cost. This study focuses on the recyclability of used coffee capsules via direct remelting under a salt flux, avoiding a separate pyrolysis step. Results were evaluated for different aspects such as metal yield, purity/cleanliness as well as gas generation during treatment.
