(i) The circular material use rate, also called 'Circularity rate', measures in percentage the share of material recycled and fed back into the economy - thus saving extraction of primary raw materials - in overall material use. The Circularity rate is thus defined as the ratio of the circular use of materials (U) to the overall material use (M). (ii) The components used to calculate circular material use rate are reported in tonnes. The Cicularity rate is presented as percentage: circular use of materials to the overall material use. (iii)All EU Member States, plus United Kingdom and the aggregated European Union.
