The circular economy model offers great opportunities to companies, as it not only allows them to capture additional value from their products and materials, but also reduce the fluctuations of price-related risks and material supply. These risks are present in all kind of businesses not based on the circular economy. The circular economy also enables economic growth without the need for more resources. This is because each unit has a higher value as a result of recycling and reuse of products and materials after use. Following this circular economics framework, the Polytechnic University of Madrid (Universidad Politécnica de Madrid, UPM) has adopted strategies aimed at improving the circularity of products. In particular, this article provides the result of obtaining recycled PLA filament from waste originating from university 3D FFF (fused filament fabrication) printers and waste generated by “Coronamakers” in the production of visors and parts for PPEs (Personal Protective Equipment) during the lockdown period of COVID-19 in Spain. This filament is used in the production of 3D printed parts that university students use in their classes, so the circular loop is closed. The obtained score of Material Circularity Indicator (MCI) of this material has been calculated, indicating its high level of circularity.

The global pandemic has taught us that we can focus the attention of the healthcare system on a clear intention when there is a looming threat. Climate action is required from multiple stakeholders particularly private sector suppliers in order to achieve the net-zero carbon emission by 2050 goal established by the Canadian government. Also building climate resilience among healthcare institutions and their supply chains is urgently needed, as they are already affected by a changing climate. By adopting a circular economy framework, the industry can move away from the current damaging take, make waste economic model and adopt a more sustainable model characterized by designing out waste and pollution, keeping products and materials in use, and regenerating natural systems. Health leaders can adopt sharing platforms, product as a service, reduce single use products, encourage extended producer responsibility, and value-based procurement in order to further these aims.

The effect of ‘supply chain management’ can be leveraged when benefits of collaboration within and beyond the capacities of individual organizations are witnessed. One of the primary tasks in reducing total supply chain costs is to understand where the costs occur in a supply chain and how each activity impacts the total supply chain costs. Most supply chains in construction usually involve multiple entities, each one in a different process. A rebar supply chain is one example where many entities are involved in different processes. The supply chain coordinator needs a supply chain cost model, which shows how each activity impacts all supply chain costs to reduce the total costs. The research suggests a supply chain cost model using time-driven activity-based costing. The proposed cost model was applied to a building construction project, followed by sensitivity analysis identifying critical activities. This method can be adapted to analyze other fragmented material supply chains in the construction industry.

The paper shows the results of an empirical study on the optimization of polymer waste supply chains based on the circular economy in Ukraine. The research shows that the main links in the activity should be harmonized for quality and quick optimization of polymer waste supply chains, including the processes of collecting, sorting, treatment, processing, and recycling of resources for maintaining the quality by total cost reduction. The research argues that the circular economy that stipulates the easy processing, recycling, disassembling, and restoring of products replaced the traditional linear model “take, produce, and throw out” that has dominated the economy by now. The study shows that the transformation of supply chains in production ecosystems forms competitive advantages at the enterprises that allow them to be more productive through efficient use of resources.

The growth in stakeholder pressures, broader sustainable supply chain management practices, and new economic models such as circular economy, has made sustainability a priority for organizations and their supply chains. To be able to manage their activities, programs, processes, and strategies, organizations have adopted and developed performance measures. Unlike other performance measures, emergy analysis quantitatively provides a real value for the work of nature to evaluate performance beyond the traditional measures that have been traditionally presented in the supply chain literature. This chapter offers an introductory explanation of how and what emergy analysis can offer in evaluating the environmental performance of supply chains. It will also consider not only the capabilities of emergy analysis but also the limitations and much-needed research to advance both fields, EA and SSCM.
