• Municipal solid waste (MSW) management drives fundamental future shifts. • An innovative and integrated biorefinery (2IB) is evaluated. • Detailed technical information on the 2IB is presented. • An emergy return of about 20 sej is made available to society by investing in 2IB. • 2IB emerges to be a powerful technological alternative to manage MSW. The rampant municipal solid waste (MSW) generation caused mainly by people's lifestyle has required technological solutions to deal with this global issue. This paper assess an innovative and integrated biorefinery (2IB) to manage MSW. The 2IB is rooted in the circular economy concept, and it differs from any other currently existing technological route in managing MSW due to its integrated processes that receives both inorganic and organic fractions at the same time, besides unveiling an innovative aspect related to thermoplastic production. Due to its scientific-based advantages, the emergy accounting (withy 'm') is considered as method to quantify the 2IB environmental performance, comparing the results with alternatives MSW management facilities. Results show that 2IB has similar performance for the three traditional emergy indicators (m-EYR of 1.17, m-ELR of 5.73 and m-ESI of 0.20) compared to incineration and landfilling, indicating low yield, moderate load on the environment, and unsustainable. On the other hand, the emergy return indicator (ERI of 20.33) indicates higher performance for the 2IB, in which for each solar emjoule (sej) – the measure unit of emergy – invested it generates a return of about 20 sej that becomes available as benefits for societal development. From an emergy perspective, results support that 2IB should be considered as a powerful technological alternative to manage MSW. This study contributes from a theoretical perspective with discussions on the emergy accounting procedures applied on systems located at far right side of energy hierarchy, while contributing from a practical perspective by providing technical information about the 2IB that supports decision makers towards more sustainable MSW management systems.

The debate about the negative impacts that production and consumption cause on the environment is in vogue. Strategies that point to a sustainable, healthy, and resilient path are being sought. One of these paths is the Circular Economy, which emerges as an alternative to reduce the socio-environmental impacts caused by the linear model of production-use-disposal, presenting opportunities to generate revenue, income, and wealth with circular processes. However, despite the circular economy being considered an essential strategy to improve overall performance toward sustainability in its three dimensions, recent research has shown that the predominant focus of circular approaches is on the economic and environmental dimensions. At the same time, the social aspects still need to be explored. This article addresses this problem, aiming to explore circular economy environmental, economic, and social elements in three economic blocs from 2000 to 2020 using the Five Sector Sustainability Model, establishing a baseline to co-create an equitable and regenerative future. The results showed that ASEAN in 2000 occupied the first position in the general ranking. The European Union had the best classification in the economic sector, and Mercosur was the best regarding social benefits. In 2020, while the European bloc was better positioned in the general ranking, the South American bloc occupied the last post in almost all sectors. Comparatively, the highest-ranked bloc in 2020 in overall sustainability is more in line with the UN SDG due to circular actions oriented towards the three fundamental pillars of sustainability. • CE advocates reducing dependence on finite resources. • The 5SEnSU model is used to monitor sustainability performance. • The sustainability of ASEAN, EU and Mercosur was analyzed. • Economic development influenced the environmental issues of the studied blocks. • EU is the highest-ranked bloc for overall sustainability.

It is known that the current linear socioeconomic system, characterized by "production-use-destination," is unsustainable and the leading cause of the depletion of natural resources. In the search for sustainable development, 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. • The sustainability of three economic blocs – ASEAN, Mercosur and EU – is evaluated. • Circularity indicators are combined with socioeconomic indicators to evaluate sustainability. • Circularity indicators are organized using the Five Sectors Sustainability Model. • ASEAN and Mercosur still pursue progress in detriment of the environment. • Deficiencies that limit the blocs' ability to adopt a sustainable approach are highlighted.
