Description
The circular material use rate (CMU), also called Circularity rate measures, in percentage, the share of material recovered and fed back into the economy - thus saving extraction of primary raw materials - in overall material use. A higher Circularitity rate value indicates more secondary materials substituting for primary raw materials i.e. avoiding the environmental impacts of extracting primary material.
Methodology
"Circularity rate (CMU) is defined as the ratio of the circular use of materials (U) to the overall material use (M).
CMU = U/M = (RCV_R - IMPw + EXPw) / (DMC + RCV_R - IMPw + EXPw)
The overall material use is measured by summing up the aggregate domestic material consumption (DM3. and the circular use of materials (M = DMC + U). DMC is defined in economy-wide material flow accounts.
The circular use of materials is approximated by the amount of waste recycled in domestic recovery plants (RCV_R), minus imported waste destined for recovery (IMPw), plus exported waste destined for recovery abroad (EXPw). Waste recycled in domestic recovery plants comprises the recovery operations R2 to R11 as defined in the Waste Framework Directive 75/442/EEC. European statistics on international trade in goods (ITGS) are used to approximate the imports and exports of waste destined for recycling, i.e. the amount of imported waste bound for recovery (IMPw), and the amount of exported waste bound for recovery (EXPw).”
