Why are some materials designated in some provinces but not in others?

The designated materials for each program are determined by the provincial governments. To streamline the reporting process for stewards who report across multiple programs, Circular Materials developed a standardized WeRecycle Material List. Individual program material lists are also available, and the portal allows stewards to choose their preferred method of reporting (either utilizing a harmonized material list or program specific lists). Please note that if you do use the WeRecycle Material List, all the material categories map directly to the program specific material lists.
