Textile industry, a part of the processing industry engaged in the production of textiles and clothing is based on textile technology. It is one of the most important branches of industrial production of consumer products. While the textile industry has long produced products such as clothing, curtains, and carpets, the places in which these products are used have expanded. With the fast advancements in science and technology in the twentieth and twenty-first century, the world has become more developed. Textiles have been utilized in the military, medicine, the automobile industry, construction, and many other industries' production facilities, including road construction, since the turn of the twentieth century. However, the average consumer is not aware and does not know which product has more or less environmental impact than others. Any product that is produced, used, or disposed of in a way that significantly reduces the damage of environmental pollution can be considered environmentally friendly. Industrialization, poor waste management system, and increased population are just some of the factors that contribute to greater environmental pollution. The textile industry has a big task to meet the needs of customers, but also a lot of competition, so different materials are used and more clothes are created while consuming a lot more energy. there is the global impact of textile production on the physical and social environment. The most significant is, of course, the greenhouse effect, but also the destruction of the ozone layer. The textile industry must take the responsibility for the entire life cycle of textile products, and this is increasingly happening in many western and developed countries. Seven of the most well-known fast fashion brands that are the biggest contributors to textile waste globally are the following: Zara, H&M, Forever 21, Uniqlo, Shein, Mango and Asos. A circular economy is one in which waste is virtually nonexistent, or, to be more specific, has been drastically reduced. The circular economy is a revolutionary different approach to the total economic processes and not only in the field of sustainable economic development and exploitation of resources but also a more socially responsible and socially balanced approach in the long-run. The circular economy idea suggests a paradigm shift that encompasses resource management in an effective and planned manner. This idea is based on eco-innovation, eco-design, cutting-edge technology, energy efficiency, and renewable energy sources. Due to the growing awareness of environmental protection and the amount of industrial waste in recent years, more companies have begun to turn to sustainable business. There is still a long way to go towards a completely sustainable business system in the world, but examples show that there is a path to progress. For Europe and its citizens, the shift to a circular economy opens up a world of possibilities. The attempt to modernize and reform the European economy in order to make it more sustainable includes it as a key component. This change is supported by sound business rationale, which enables organizations to grow economically and become more competitive. Directives and measures such as the WFD will become a key factor in regulating countries and that means people to behave in accordance with circular economy and sustainability.
