FEDZ has been refining waste classification approaches in an attempt to increase the percentage of recyclable and reusable waste. Initially, valueless waste was processed by outside agencies. Starting in 2019, valueless waste is further classified into 21 categories of production waste and 5 categories of domestic waste, which are then treated and transformed into valuable objects. To motivate staff to improve classification methods, FEDZ conducts training, promotion and monthly competitions to help them understand that sustainability should be a daily practice. In 2019, the project helped FEDZ turn 814 metric tons of valueless waste into valuable objects that can be reused, generating NT$12 million in benefit a year.
