Nationwide data on waste, its quantity and contents last became available in 1999, covering the years up to 1998, although some data collection efforts have been made since then, but not in a systematic manner. For example, Sarajevo Canton has been collecting various kinds of waste data since 1998 and sanitary' landfill operators have also started to collect data. The most recent attempt to collect data on municipal and industrial waste was undertaken in 2009 by the Agency for Statistics, in line with the Law on Statistics.
