For the sake of achieving the goals of economic growth and welfare increase, world resources are consumed recklessly and cause the generation of very high amounts of waste. This imbalance, consisting of production and consumption phases, has caused the ecosystem to be negatively affected. Although the waste recycling sector is an important sector in Turkey, additional studies are needed to ensure social awareness on waste management, research and development studies, and conversion of textile waste into high value-added products. A significant part of the waste in Turkey is used in yarn production. In this study; A research was conducted on the recycling processes of cotton yarn waste in a business for sustainability. Breaking strength values of yarns containing 10-50% waste in 3 different yarn counts, namely Ne 10, Ne 20 and Ne 30, were estimated by fuzzy logic modeling and the effects of textile waste on the environment and human health were examined.
