Strengthening Campus Environmental Protection Measures; Building a Resource Circulation System Together
The university is committed to maintaining campus environmental quality by implementing waste reduction and resource recycling initiatives in accordance with relevant regulations of the Ministry of Environment, thereby promoting the concept of resource circularity. In addition to establishing comprehensive resource recycling facilities on campus, the university also contracts with licensed waste disposal companies to handle the collection, transportation, and processing of waste, ensuring proper waste management.
In addition, the university promotes waste sorting awareness through official email communications and various advocacy initiatives, encouraging faculty, staff, and students to jointly participate in resource recycling and waste reduction efforts. These actions aim to reduce environmental impact, enhance campus environmental quality, and advance toward the goal of a sustainable campus.
General Waste Treatment
NKUST implements the 3R policy (Reduce, Reuse, Recycle) by continuously promoting waste reduction, resource recycling, and paperless initiatives. The university replaces incineration with document water washing to reduce environmental impact and enhance resource recycling efficiency.
Treatment of Experimental Waste
Chemical waste liquids, waste lubricating oil, expired chemical reagents, and biomedical waste (such as animal carcasses) are all entrusted to licensed and qualified waste disposal contractors for proper treatment. The University also utilizes the Ministry of Environment reporting system for declaration and statistical management. In 2025, the University commissioned the Environmental Resources Research and Management Center of National Cheng Kung University to handle waste liquids from the Jiangong, First, and Nanzih campuses.
Construction waste generated by the university’s building projects is handled by licensed contractors. Remaining soil and rock materials are classified, managed, and recycled in accordance with regulations to reduce environmental impact and promote resource circulation.

Implementation Status
In compliance with regulations, construction waste such as soil, sand, gravel, bricks, and concrete blocks is properly sorted for reuse or transport.
The University currently has approximately 95 major teaching and administrative buildings. Among them, 17 buildings are over 40 years old, 27 buildings are 30-40 years old, 22 buildings are 20-29 years old, and 29 buildings are under 20 years old. Overall, the campus buildings are relatively aged, and approximately two-thirds of the facilities are in a phase requiring frequent maintenance and repairs. As a result, demand for the renovation of buildings, roads, plazas, sports fields, and other basic infrastructure—as well as the refurbishment of aging spaces requested by various units—has been increasing year by year. Consequently, the volume of construction waste fluctuates in accordance with the number of contracted projects and the scope of renovation works.
