Abstract
This thesis examines the potential environmental impacts of a reusable polyester cleanroom suit and evaluates various end-of-life scenarios to identify the most sustainable option. A comparative analysis was conducted on thermal disposal, mechanical recycling, and thermo- mechanical recycling. The study offers valuable insights into the ecological effects of the cleanroom suit and the recycling processes. Through extensive literature review, the requirements for input materials as well as the energy, water, and chemical consumption of the recycling processes were assessed. An LCA screening revealed that the production and use phases, particularly washing, detergent consumption, fabric production, and wet treatment processes, represent the most significant environmental hotspots. The transport phase was found to be of minor importance, and end-of-life impacts were negligible. Among the end-of-life scenarios, thermo-mechanical recycling in Austria, with an output of 100% spinnable fibers, yielded the most favorable environmental outcomes, followed by mechanical recycling. Recycling processes were shown to substantially reduce the environmental burdens of the cleanroom suit, particularly with respect to ozone depletion potential.The findings of this research highlight that recycling presents significant opportunities for enhancing sustainability in the textile sector. However, further development is required to improve the efficiency and quality of recycled materials. Moreover, transparent reporting of process data and inputs is essential for advancing this field. In conclusion, while recycling holds promise, a holistic approach, combined with systemic changes towards a circular economy, is vital for achieving a truly sustainable textile industry.
