*Notes to table 3-10: *1: Sector specific waste deposits is an "other controlled deposition" category, including for example special deposits for coal combustion residues in some countries and industry's own deposits (subject to authorities control). *2: Note that double counting can not be ruled out in overall sums for waste treatment - depends on national practices and how data were reported in questionnaire responses. Therefore, these sums were not included in the table.
