Total volume organic waste produced this year (tons)

     In 2024, National Chiayi University (NCYU) generated a total of 91.027 metric tons of organic waste, primarily from four major sources: used cooking oil, food waste, paper, and fallen leaves. Due to the university’s green campuses and extensive tree coverage, fallen leaves constitute the second largest portion of organic waste, following paper, which remains the primary contributor.  All organic waste is properly collected and processed at a 99.83 % treatment rate. Food waste is handed over to the Chiayi City Environmental Protection Bureau for composting and resource reuse, while fallen leaves and pruned branches are shredded into woodchips and composted for campus landscaping. Recycled paper is collected by certified recycling contractors, and used cooking oil is recovered through authorized recycling vendors.

     These measures highlight NCYU’s strong commitment to responsible waste management, resource circulation, and organic waste minimization, aligning with SDG 12 (Responsible Consumption and Production) and contributing to a more sustainable and circular campus ecosystem.
