Befesa Salzschlacke

Befesa Salzschlacke GmbH, part of the Befesa group, is a major player in the recycling of salt slags, a byproduct of the aluminum industry. These slags, which contain hazardous substances, are processed to recover valuable materials like aluminum concentrates, aluminum oxides, and salts. Befesa's recycling process is designed to handle industrial waste safely while reducing environmental impact.

The company operates several facilities in Germany, including those in Hannover and Lünen, which have a combined capacity to treat around 380,000 tons of salt slag per year. These plants use advanced technologies to recover usable products from the recycling process, contributing to circular economy practices in the aluminum sector. Befesa is considered a leader in salt slag recycling in Europe​
