Summary: In this paper, we discuss the open circular economy business model, which differs from the typical circular business model by incorporating external raw materials into the internal sustainable production cycle. This model allows for greater flexibility and a more equitable distribution of benefits among external actors. Through a case study of an Italian manufacturing company, we provide insights into the strengths and weaknesses of this model.

Summary: The circular economy is gaining momentum due to its promised environmental, social, and economic benefits. Implementing circular economy business models (CEBMs) is challenging for organizations, but this study examines the impact of institutional policies on CEBM development, including consumption policies. The results show that consumption policies have a positive effect on CEBMs, although their influence diminishes over time. Regulation is found to be the most impactful policy, emphasizing the role of institutional policies in driving demand for circular economy products and achieving sustainability.

Summary: The study investigated consumer responses to circular economy product labels and their willingness to pay for products with different levels of circularity, finding that most customers prefer more circular products and are willing to pay more for products with low or moderate levels of circular content. However, willingness to pay decreases as the proportion of recirculated content increases.

Summary: Product circularity can be understood as a three-dimensional concept, encompassing high material recirculation, high utilization, and high endurance. These dimensions should be measured and reported separately, rather than as a composite metric, and different applications may have opportunities to improve circularity through certain dimensions better than others.

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.
