Metallåtervinning Arena (unofficial English translation: Metal recycling Arena), formerly named Gränbyhallen, is an indoor arena located in Uppsala, Sweden, and built in 1974. It consists of three arenas: "A-hallen", "B-hallen" and "C-hallen".
A-hallen is the biggest part of the arena and has a capacity of 2,800 spectators and is where Almtuna IS and Uppsala HC play their home games. B-hallen has a capacity of 350 spectators, and C-hallen has a capacity of 250. The arena opened in 1974 and was renovated following Almtuna IS's promotion to the second-tier league Allsvenskan (now named HockeyAllsvenskan), prior to the 2001–02 season. The current spectator record was set on March 27, 2010, when 2,916 spectators visited the arena to see Almtuna IS meet Södertälje SK in the Kvalserien qualification for the top-tier league Elitserien (now named the SHL).
