The indicator measures the quantities of selected waste categories and by-products that are shipped between the EU Members States (intra-EU) and across the EU borders (extra-EU). Five classes have been selected: plastic; paper and cardboard; precious metal; iron and steel; copper, aluminium and nickel. The indicator includes the following variables: • Intra EU trade of selected recyclable raw materials (measured as the Imports from EU countries). • Imports from non-EU countries and exports to non-EU countries of selected recyclable raw materials (as regards extra-EU trade). The indicator is based on International Trade in Goods Statistics (ITGS) published by Eurostat. The scope of the “recyclable raw materials” is measured in terms of relevant product codes from the Combined Nomenclature used in International Trade in Goods Statistics.
