“…Given the wide range of perspectives, formats, and scales, Saidani, Yannou, Leroy, Cluzel, and Kendall (2018) suggest a taxonomy of different CE indicators. However, many reviews address specific aspects of CE, such as resource efficiency (Huysman et al, 2015), eco-innovation (Smol, Kulczycka, & Avdiushchenko, 2017), or resource recovery from waste (Iacovidou et al, 2017). At the product and organizational levels, possible metrics are discussed by Tecchio et al (2017) and Pauliuk, EU policy suggests a monitoring framework focusing on waste (e.g., waste generation and food waste) and recycling (e.g., recycling rates [RRs], contribution of recycled materials to raw materials demand), complemented with more economic and socially oriented indicators (EC, 2018b).…”
