| dc.description.abstract | In recent years, because of ＂fast fashion＂, consumers have accelerated the speed of changing clothing, resulting in an increase in the number of used textiles. According to the data of the Environmental Protection Administration Executive Yuan, R.O.C in August 2018, the total amount of used clothes recycled was about 63,211 tonnes in 2017. In fact, the used clothes discarded by the public as waste were countless. Due to demand uncertainty, the amount of waste textiles before consumption was also considerable. If it cannot be properly disposed, it will impose a burden on the environment. Therefore, it is imperative to completely recycle and remanufacture waste textiles. And it is expected that the waste textile recycling industry will develop well.
In order to improve the proportion of waste textiles and increase the value of reverse supply chain, this study selected waste textile processors as research objects, and extended the mathematical model proposed by Sarkar and Moon (2014) to the recycling industry to explore before and after investment for cost and profit. The change, considering the simultaneous improvement of the proportion of waste textiles and the cost of process changes, and proposed different results of the recycling process (chemical, physical). Considering to improve the proportion of waste textiles and reduce the cost of process changes at the same time, and propose different results from different recycling methods (chemical methods, physical methods).
This study mainly constructs a mathematical model for the profit maximization of waste textile processors. Through the profit analysis brought by this two recycling methods to provide the decision makers different investment schemes. It hopes to improve the value of sustainable recycling.
