In other large cities some informal separation and collection of materials for recycling occurs. Other informal recycling occurs at disposal sites where unauthorised groups scavenge for metals, plastic, paper and wood. About 60 private companies are dealing with recycling of a broad range of waste fractions, but predominantly of scrap metal. Not all of them have an environmental permit from MoEFWA. It is estimated that about 65 large uncontrolled sites and numerous small sites are currently in operation in Albania.
