SKO contains a table of equivalence, ie. comparative review of two classifications of waste: European list of waste - LoW (European List of Waste) and the statistical classification of waste EWCStat / Version 4 according to Annex III of Regulation EC 849/2010.
The catalogue of waste is used for data collection (Regulation on the classification of waste and its processing procedures, processing and removal of " Official Journal CG”, No.68/09) which complies with the European List of Wastes (LoW) and contains a list of more than 800 species systematized according to properties of the waste and place of origin in 20 groups.
Each group has two digits from 01 to 20 which marks the activity in which the waste originated.
Subgroups within the group are marked with four digits, of which the first two digits belong to the proper group, and the third and fourth represent a process where the waste originated.
According to part of the process in which the waste generated within the sub-species in which it is classified, the waste is marked with six digits, of which the first four digits belong to the subgroup, and the fifth and sixth represent a part of the process in which the waste originated. Waste Catalogue as a legal basis for European control and supervision of waste can not be used for statistical purposes, therefore the statistical classification of waste is adopted (EWCStat / Version 4). According to Annex I of Regulation EC 849/2010.
