These containers are more commonly referred to as Aseptic Containers. They are made from paper(70%), polyethelene (24%) and aluminium (6%). The conglomeration of materials makes recycling of aseptics more difficult and thus more costly. However, many haulers do accept them in the blue bin. Call your local hauler to find out if they accept aseptics for recycling. More and more product manufacturers are beginning to adopt this technology. As a result, CAW is sponsoring SB 1625 which will expand California's Bottle Bill to include more container types which will include aseptics.
