Using the five sectors sustainability model to verify the relationship between circularity and sustainability

It is known that the current linear socioeconomic system, characterized by production-use-destination, is un-sustainable and the leading cause of the depletion of natural resources. In the search for sustainable develop-ment, several actions to preserve resources in use for as long as possible have been proposed in recent decades, such as cleaner production, ecoefficiency, industrial ecology, industrial ecosystems, industrial symbiosis, and the circular economy. Although circularity and sustainability are increasingly present on the agenda of academics, entrepreneurs, and government sectors, the relationship between the two concepts is still under construction. In this sense, this work aims to verify, using the Five Sectors Model of Sustainability, the relationship between circularity and sustainable development in ASEAN, Mercosur, and the EU, considering economic, social, and environmental indicators in the periods between 2000 and 2020. The selected indicators with their respective goals were applied and weighted through Goal Programming. From the primary and secondary data analysis, it was not possible to conclude that circularity alone guarantees sustainability, despite contributing significantly to sustainable development. However, the results obtained in the 5SEnSU model made it possible to verify that the EU has a superior performance for sustainable development of the other two blocks and that the impacts generated in the economic system (sector 3) of the analyzed blocks benefited social sectors (4 and 5) to the detriment of environmental integrity (sectors 1 and 2). Some challenges still need to be mitigated, such as those related to excessive consumption and waste discharge, so that a circular economy can effectively contribute to global sustainability.

Automated summary

This work aims to examine the relationship between circularity and sustainable development in ASEAN, Mercosur, and the EU using the Five Sectors Model of Sustainability. The analysis of economic, social, and environmental indicators reveals that circularity contributes significantly to sustainable development, but it is not sufficient on its own. The study finds that the EU outperforms the other two blocs in terms of sustainable development, with some negative impacts on environmental integrity. Mitigating challenges related to excessive consumption and waste discharge is crucial for the circular economy to effectively contribute to global sustainability.
