Test and development of a new model for the dispersion and impact assessment of PUR foams in alpine environment

This master’s thesis presents the design, implementation, and evaluation of a dispersion model tailored for assessing the environmental impact of polyurethane foams in alpine environment. Polyurethane foams, defined also as PUR, are widely used in various applications, ranging from insulation to packaging, yet their environmental footprint remains a concern, especially in sensitive mountain ecosystems. The aim of this project is to focus on the dispersion of this kind of organic polymer as a consequence of its usage in the sole of trekking shoes. The proposed model integrates data on foam production, usage, and disposal, accounting for the unique characteristics of alpine environments, such as temperature fluctuations, altitude effects, and ecosystem vulnerabilities. Through a comprehensive life cycle assessment (LCA) framework, the model evaluates the emissions, and potential ecological consequences associated with polyurethane foam utilization across its entire life cycle. By simulating dispersion patterns and environmental interactions specific to alpine settings, but also associated to other different morphologies, this research aims to provide stakeholders with valuable insights into the sustainability implications of polyurethane foam usage in mountainous regions. The findings contribute to the advancement of LCA methodologies tailored for complex environmental contexts, facilitating informed decision - making towards more environmentally responsible material choices in alpine environments.
