The Müller-Guttenbrunn Group is an Austrian recycling company based in Amstetten, Lower Austria. It processes end-of-life vehicles, waste electrical and electronic equipment, photovoltaic modules, ferrous and non-ferrous metals, shredder residues and plastics, returning around 850,000 tonnes of secondary raw materials to production every year.
The company was founded in 1954 by Herbert Müller-Guttenbrunn as an iron trading business in Waidhofen an der Ybbs and is run today as a family business in its fourth generation. The group comprises MGG Metrec, MGG Metran, MGG Polymers and Danubia Speicherei in Austria, together with companies in Germany, Czechia, Hungary and Romania and a trading operation in Switzerland.
Its defining feature is the depth of recycling: MGG separates material streams beyond the shredder into single-grade metal fractions and plastic recyclates. Its subsidiary MGG Polymers recovers single-grade ABS, PS and PP from electrical waste. The company is certified to ISO 9001, ISO 14001 and EN 50625-1 and operates a certified photovoltaic module plant in Amstetten.
