Summary: The study found intense awareness and legislative support in Slovenia for Industrial Symbiosis (IS) and Urban Symbiosis (UrS), in line with EU regulations. However, there has been surprisingly little waste-to-energy recovery since 2010. Reuse of by-products for energy or new products is almost non-existent. Urban strategies in Slovenia are insufficient in providing concrete guidelines for the development of IS and/or UrS.

Summary: Plasma gasification is a sustainable process that converts plastic waste into fuel oil. A prototype system is being tested to validate this plasma treatment as a strategic vision. The system includes a plasma reactor with a waste capacity of 200 tons per day. The annual plastic waste production in Makkah city from 1994 to 2022 ranges from 224,000 tons to 400,000 tons, with significant amounts of recovered pyrolysis oil and diesel oil. The economic evaluation shows promising sales revenue and cash recovery from the energy extracted from plastic waste.

Summary: This study utilized material flow analysis to quantify the energy recovery potential of MSW in Madrid for 2030. The results suggest a potential decrease in overall energy recovery due to increased recycling rates of plastic, paper, and cardboard. However, waste streams suitable for energy recovery represent a significant portion of the MSW generated in the scenarios for 2030.

Summary: The purpose of this article is to identify barriers, drivers, and the structure of relationships that support industrial symbiosis initiatives in a network of Brazilian manufacturing companies. Economic, internal, and technical barriers exist within the relationships, but the main drivers are cost reduction, new products or revenue sources, and legal requirements. The companies mainly engage in direct and reverse transfers through closed-loop relationships.

Summary: This study examines the economic and environmental effects of transitioning towards more circular food systems in the European Union (EU27) by feeding animals with low-opportunity-cost feed and better utilizing local feed resources. The results show that providing subsidies for circularity and promoting the use of low-cost feed can increase animal production, but also have negative impacts on land use and emissions. On the other hand, promoting domestic feed sourcing through import tariffs can decrease animal production and greenhouse gas emissions in agriculture. However, complementary policies are needed to mitigate drawbacks and enhance benefits of a more circular agri-food system.
