Public awareness has increased manufacturers responsibility and forced them to shift from linear to the circular production line to reduce the amount of environmental impact such as; energy and freshwater consumption, toxic and fertilizer usage and cutting down the use of raw material. Also, some new business strategies like fast fashion which is a recent trend in the fashion industry by offering fast changing trend and inexpensive designs accelerate the process of purchasing new clothes that end up in landfills. Recycling, remanufacturing and reusing are some practices that can be done to minimize the environmental impact and to keep used clothes out of the landfills. One of these preventive actions is textiles recycling which involves so many uncertainties, such as quality, quantity, and type of the used materials. To address this problem, a discrete event simulation model is proposed to study the changes in the recycling process. The main focus of the model is on the interaction between different components in a textile recycling system to increase the number of recycled materials to return them into the supplier. Moreover, the performance of the servers is studied in order to run different scenarios. These scenarios are proposed and have been chosen based on the Welch method. Key words: Fashion Industry, Second Hand Clothing, Textile, Textile Recycling, Remanufacturing, Supply Chain, Simulation, Enterprise Dynamics. iv DEDICATION Dedicated to My beloved father, mother, and brother. v ACKNOWLEDGEMENTS First of all, I would like to express my special thanks to my supervisor, Dr. Z. Pasek for his detailed guidance and all his support and mentorship to complete my program. Also, deeply I am grateful to him for giving me the opportunity to start my M.Sc. under his supervision. I would also like to thank Dr. L. Miller; it was an honor to have her in my committee. Furthermore, I would also like to acknowledge with much appreciation to Ms. Angela Haskell for providing me continuous encouragement throughout my years of study. vi TABLE OF CONTENTS DECLARATION OF ORIGINALITY ............................................................... iii ABSTRACT ....................................................................................................... iv DEDICATION ..................................................................................................... v ACKNOWLEDGEMENTS ................................................................................. vi LIST OF TABLES .............................................................................................. xi LIST OF FIGURES............................................................................................xii LIST OF APPENDICES .................................................................................... xv LIST OF ACRONYMS ..................................................................................... xvi CHAPTER 1: INTRODUCTION ......................................................................... 1 1.1 Introduction to textile recycling .................................................................... 1 1.2 Clothing recycling ........................................................................................ 4 1.3 Apparel industry ........................................................................................... 5 1.3.1 Fast Fashion ......................................................................................... 5 1.4 Textile waste ................................................................................................ 7 1.5 Closed loop fashion system .......................................................................... 9 1.6 Mechanisms to recover the value of used products ..................................... 10 1.6.1 Repair and reuse ................................................................................. 11 1.6.2 Remanufacturing and upcycling ......................................................... 11 1.6.3 Recycling ........................................................................................... 13 1.6.4 Reasons to do recycling ...................................................................... 15 1.6.5 Disposing ................................................................................................ 16 1.6.6 Landfill Disposal ..................................................................................... 17 vii 1. 7 Share of different material in clothing ....................................................... 19 1.8 Problem statement ...................................................................................... 23 1.9 Contribution of this research ...................................................................... 24 1.10 The objective of the study ........................................................................ 24 1.11 Proposed approach ................................................................................... 25 1.12 Research outline ....................................................................................... 26 CHAPTER 2: LITERATURE REVIEW ............................................................ 27 2.1 Relevant literature review ........................................................................... 27 2.2 Gap in the literature and plan of work ................................................. 33 CHAPTER 3: SOLUTION APPROACHED AND WORKING ASSUMPTIONS ................................................................................................ 34 3.1 Simulation models ...................................................................................... 35 3.1.1 Discrete-event simulation ................................................................... 35 3.2 Modeling for simulation ............................................................................. 36 3.2.1 Model architecture ............................................................................. 37 3.2.2 Sub-system 1: Product generation ...................................................... 37 3.2.3 Sub-system 2: After use phase ............................................................ 37 3.3 The main framework of the model .............................................................. 38 3.4 Simulation process ..................................................................................... 43 3.5 Description of the recycling process ........................................................... 43 3.6 Notations and assumptions ......................................................................... 47 3.6.1 Notations............................................................................................ 47 3.6.2 Assumptions .....................................................................................
