Analisi di rischio di un impianto di produzione di R-PET

This thesis focuses on the Quantitative Risk Assessment (QRA) of a pilot plant dedicated to the production of recycled polyethylene terephthalate (rPET). The production process of rPET is a critical phase in the material's lifecycle, as it allows for the production of new plastic products from recycled plastic, reducing reliance on virgin raw materials and contributing to environmental sustainability. However, the transformation of rPET entails operational and environmental risks that require careful management. The objective of this research is to identify and analyze the potential risks associated with the rPET processing stages, including extrusion, melting, and the formation of new plastic products. Using simulation models and risk analysis techniques, the thesis evaluates the likelihood and severity of incidents that could impact the surrounding environment and human health, such as the release of volatile chemicals or the risk of fires and explosions. The results of the QRA suggest that the implementation of advanced safety systems, combined with optimal operational management, can significantly mitigate the risks associated with the transformation of rPET. Preventive and corrective measures are also proposed to minimize the consequences of potential accidents. This research provides an important contribution to understanding the environmental risks in rPET transformation plants, offering guidelines for safe and sustainable management of the production process.
