Special Issue Information

Dear Colleagues,

As we all work together to build a sustainable future, the scientific community is increasingly contributing towards innovative processes and material technologies that can drive progress in a more eco-friendly manner. Extrusion technology is a versatile and smart engineering tool employed across various industries and it stands as a model of hope in this endeavor. The integration of extrusion with advanced engineering principles not only promises to revolutionize the production of environmentally friendly materials but also holds the potential to transform waste and byproducts into valuable resources. This research area, therefore, is not only scientifically intriguing but also of paramount importance for the global community. We are excited to delve into the depths of this field, exploring its multifaceted implications and the role it plays in fostering a circular economy.

This Special Issue is dedicated to the exploration of “Extrusion Technology and Engineering for Sustainability and Circular Economy”. It is designed to align with the journal's scope, which emphasizes the promotion of sustainable practices and innovative engineering solutions. By focusing on the intersection of extrusion technology, sustainability, and the circular economy, this issue aims to bring together a diverse array of scholarly contributions.

In this Special Issue, we welcome original research articles and reviews that delve into the various aspects of extrusion technology and its role in promoting sustainability and a circular economy. The suggested themes and research areas for submissions may include, but are not limited to, the following:

  • Advanced Rheology in Extrusion Processes;
  • Modeling and Simulation of Extrusion Systems;
  • Chemistry and Material Science in Extrusion Technology;
  • Waste Plastic Management and Recycling through Extrusion;
  • Food and Non-food Industry Applications of Extrusion.

We encourage submissions that not only highlight theoretical underpinnings but also showcase practical implementations and case studies. The goal is to foster a comprehensive understanding of how extrusion technology can be leveraged to achieve sustainable outcomes in diverse sectors.

I look forward to receiving your contributions and am eager to see the innovative ideas and research that will be presented in this Special Issue.

The rapid increase in waste electrical and electronic equipment (WEEE) creates major environmental and governance issues in developing countries like Ecuador struggle because they with minimal formal collection and recycling rates. This research presents a potential sustainable management approach that tracks products through their life cycles while following circular economy principles that include product extension and material extraction and waste minimization. A systematic literature review (SLR) using the PRISMA methodology combined with a bibliometric analysis found essential global strategies and technological frameworks and regulatory frameworks. The analysis of articles demonstrates that information management systems (IMSs) together with digital technologies and consistent regulations serve as essential elements for enhancing traceability and material recovery and formal recycling processes. A WEEE management IMS model was developed for the Ecuadorian market through an analysis of the findings; it follows a five-stage development process, starting from the technological infrastructure setup to complete data visualization integration. The proposed model is designed to enable public–private–community partnerships using digital tools that promote sustainable practices. The combination of circular strategies with traceability technologies and strong regulatory frameworks leads to improved WEEE governance, which supports sustainable system transitions in emerging economies.
