• This thesis examines the potential for small and medium-sized enterprises (SMEs) in the German apparel industry to enhance circular capabilities. Given the urgency of environmental issues in garment production, the thesis delves into the broader context of the textile and apparel industry, circularity principles, circular product design, as well as business and regulatory framework conditions. However, this transformation necessitates substantial innovation, which can be challenging, especially for SMEs facing resource constraints. A utility analysis-based tool to support SMEs' circularity journeys is introduced, by systematically evaluating textile fibers. This approach assists SMEs in optimizing material choices and complying with sustainability standards and reporting. To demonstrate its effectiveness, the tool is applied for HAKRO GmbH, a SME in the German apparel industry. The assessment results indicate prioritization of specific fiber choices, emphasize knowledge gaps, and spotlight opportunities for innovation and circularity. The tool's systematic approach enables SMEs like HAKRO GmbH to strategically select material options, streamline innovation efforts, and align with CE principles. Ultimately, this research contributes to advancing CE transitions within the apparel industry by offering insights into enhancing circular capabilities for SMEs and facilitating informed decision-making through a utility analysis-based approach.
