Waste statistics are compiled according to the Regulation (EC) No. 2150/2002 amended by Commission Regulation (EU) No. 849/2010 which requests the Member States to submit data on the generation and treatment of waste, every two years following the first reference year 2004. Data on waste statistics is obtained from the waste treatment facilities. Such information is used to compile waste generation data according to a breakdown of waste categories for aggregated NACE activities and households. Data on waste treatment according to a breakdown of waste categories for five treatment types (Energy recovery, Incineration, Recovery, Disposal on land and other disposal) is also compiled.
