A full methodology for this indicator is available in the document entitled, “Global Chemicals and Waste Indicator Review Document” (UNEP, 2021).

National Recycling Rate is defined as the quantity of material recycled in the country plus quantities exported for recycling minus material imported intended for recycling out of total waste generated in the country. Note that recycling includes codigestion/anaerobic digestion and composting/aerobic process, but not controlled combustion (incineration) or land application.

$R e c y c l i n g r a t e = \frac{\begin{matrix} (M a t e r i a l r e c y c l e d + M a t e r i a l e x p o r t e d i n t e n d e d f o r r e c y c l i n g \\ - M a t e r i a l i m p o r t e d i n t e n d e d f o r r e c y c l i n g) \times 100 \end{matrix}}{T o t a l w a s t e g e n e r a t e d}$

$T o t a l w a s t e g e n e r a t e d = W a s t e f r o m m a n u f a c t u r i n g (I S I C 10 - 33) + W a s t e f r o m e l e c t r i c i t y, g a s, s t e a m a n d a i r c o n d i t i o n i n g s u p p l y (I S I C 35) + W a s t e f r o m o t h e r e c o n o m i c a c t i v i t i e s (e x c l u d i n g I S I C 38) + M u n i c i p a l w a s t e (e x c l u d i n g c o n s t r u c t i o n a n d m i n i n g)$

It is proposed that recycling rate is disaggregated by type of waste, including e-waste and other waste types (such as packaging waste and metals). For the disaggregation by waste stream, the formula will be the same but particular waste types will be evaluated. (Existing data on e-waste and the importance of e-waste means that this disaggregation will be collected at the global level.)
