This project develops a System Dynamics Model (SDM) to aid city plastic waste management planning, with a case study focused on the City of Gold Coast. Drawing on literature, stakeholder workshops, and prior research, the SDM will map key system variables and feedback loops, enabling plastic ‘futures’ scenario testing through developed simulation software. A user-friendly dashboard will allow stakeholders to explore how different plastic waste management policies, technologies, and strategies impact key performance indicators such as recycling rates, landfill reduction, and circular economy outcomes. The project will support data-driven decision-making and provide a roadmap for future plastic waste management planning in Australia and internationally. Considerations for advanced resource recycling facilities, waste-to-energy plant, and other contemporary waste infrastructure augmentations often proposed for modern cities will be considered.
