Fashion industry is considered to be one of the most wasteful consumer industries globally and this fact can be tacked back to fast fashion‘s significant development the past decades. According to European commission data published on August 2021 (Kohler, Watson, Trzepacz, Ran, & Danneck, 2021), an average European citizen buys 60% more items of clothing every year and keeps them about half of the time compared to 15 years ago. This proves that clothing tends to become from a durable good to a frequent purchase. Although, currently only 1 percent of second-hand textiles are recycled into new clothes, the circular trend is expected to have great impact by receiving the support of more and more companies willing to adopt green practices and integrate from a linear to a circular supply chain. Meanwhile, the European Union adopted on March 2020 the new “Circular Economy Action Plan” as a result of the European Union’s “Green deal” and it’s expected to expand year by year and apply obligatory recycling and circularity practices for all mainstream fashion companies. Fiber to fiber recycling where textile waste is processed and turned into new fibers ready to be reused, is an innovative practice that embrace circularity in Fashion industry. Technologies like mechanical recycling for some of the main used materials are already established while other technologies like chemical recycling is under development, promising great impact on the textile recycling. By focusing on the Greek fashion industry, the research was conducted in order to find out the way in which companies manage the three stages of take – make – waste of their supply chains and whether sustainable or circular practices have been already adopted or there is the willingness and the interest from the companies to insert them. The gap between actions already implemented by Greek industries and the principles of circularity will be explored. Through the results of a questionnaire and interviews with 9 Greek industries, the research will analyze circular strategies – of micro and small sized brands – across the stages of their supply chains and the inhibiting factors of the integration from a linear to a circular supply chain. Conclusions and recommendations for further studies are proposed in the end of the current thesis.
