Modelling and communicating the effects of plastic recycling systems on plastic quality and economic viability

Abstract

Plastic production and waste treatment significantly impact climate change and contribute to the environmental challenge of plastic littering. This research, a collaborative effort with TNO as part of the InReP project, aims to enhance the sustainability of plastic recycling systems. The study focuses on advancing plastic recycling to make it more techno-economically and environmentally efficient, a goal that we are collectively working towards. This thesis has two primary objectives: first, investigating the key characteristics and quality of recycled plastics, and second, designing a graphical user interface (GUI) for the PRISM (Plastic Recycling Impact Scenario Model) to present complex data to various stakeholders. The practical implications of this research are significant. By integrating information from industry, literature, and the PRISM model, the research identifies critical attributes of recycled plastics, determines their composition, and assesses their properties to derive quality factors. These quality factors are then compared to evaluate the efficacy of the recycling processes, providing valuable insights for the industry and policymakers. Additionally, the GUI's development ensures that PRISM's data is accessible and interpretable, facilitating informed decision-making in plastic recycling. The GUI's development highlights the importance of making complex model outputs understandable for various stakeholders, thereby supporting thoughtful choices in plastic recycling. In conclusion, this research combines an in-depth analysis of plastic quality characteristics with developing a user-friendly interface for PRISM. By addressing these interconnected aspects, the study contributes to making plastic recycling more effective and environmentally friendly, supporting the broader goal of a sustainable future.
