A Complex Circular-Economy Quality Indicator for Assessing Production Systems at the Micro Level

Measuring circular-economy progress requires indicators to examine the implementation of management systems. A complex quality indicator for assessing production systems at the circular-economy micro level was proposed. One innovative aspect of this evaluation of quality indicators is the classification of a set of sixty selected options divided into four core groups (technical, environmental, economic, and social). The second one is the use of a trimmed-mean method to summarize the individual options score into core groups and complex circular-economy indicators of analyzed production systems. The individual options were weighed according to indices defined by the professional team. Here is presented a case study of the use of developed complex quality indicators, including a comparison of two sodium tripolyphosphate production processes. The calculated indicator of the new method was higher, at 204.8%, than the indicator of the old method. This confirms the significant advantage of the new technology.
