Sorted waste is transferred to certified recycling contractors for resource recovery and reuse
Campus waste recycling process:
Set up garbage and resource recycling bins at fixed locations → Send the staffs to collect waste daily → Transported to the on-campus resource recycling field → Items are reclassified and cleaned up → Resource waste is regularly cleared, transported and sold by resource recycling manufacturers, and non-resource waste is cleared, transported and disposed of by the cleaning team of the local government's Environmental Protection Bureau.
Food waste is handed over to the Chiayi City Environmental Protection Bureau for recycling and reuse as compost
Discarded tree branches are shredded into woodchips using a wood crusher for reuse in campus landscaping
The woodchips are used to pave the walkways in the botanical garden, providing paths for visitors and enhancing the campus landscape
Compost made from withered branches and leaf litter is used for tree planting and campus landscaping

National Chiayi University Waste Management System
National Chiayi University has always adopted the principles of Reduce, Reuse, and Recycle for campus waste management. The implementation plans for Reduce, Reuse, and Recycle, and some data, are elaborated upon below:
1. Reduce:
National Chiayi University (NCYU) adopts data-driven meal preparation in canteens to minimize food waste and has banned plastic straws and free plastic bags in campus shops to reduce single-use items. Administrative operations are streamlined through a paperless workflow, achieving 84% online sign-offs for incoming and 98% for outgoing documents in 2024. The university also maintains a high green procurement rate of 99.85%, with NT$26.1 million in eco-labeled products purchased. In construction, waste is minimized through balanced earthwork design and the reuse of excavated soil for road backfilling and maintenance, contributing to resource efficiency and waste reduction.
2. Reuse:
Canteens provide reusable tableware and offer discounts for those who bring their own utensils. A second-hand furniture and equipment claim platform and annual flea market encourage reuse, with proceeds supporting the university’s emergency relief fund. The Creative Design Studio refurbishes discarded furniture and wooden materials for reuse by students and staff. A book-exchange program further promotes material reuse within the campus and the community. In addition, a second-hand bicycle donation program supports international students by providing sustainable transportation options.
3. Recycle:
Waste across all campuses is sorted into resource, food, and non-resource categories, managed through a systematic waste management process. Smart recycling machines introduced in 2024 enhance waste-sorting efficiency and promote digitalized waste tracking. Organic waste, such as fallen leaves and pruned branches, is processed into compost or shredded into woodchips for landscaping and botanical garden pathways. Agricultural organic waste, including poultry feathers, is converted into organic fertilizer for vegetable cultivation, forming a low-carbon circular reuse model.
4. Educational Promotion:
The Environmental Protection and Safety Management Center regularly conducts awareness activities, including the annual Earth Day recycling campaign (April 15–29, 2024), which encourages waste sorting and resource recycling through incentives. The center also collaborates with iNaturalist Taiwan to offer ecological observation courses that integrate biodiversity awareness into daily campus life. These initiatives foster a culture of environmental responsibility and sustainable living, supporting SDG 12 (Responsible Consumption and Production) and SDG 13 (Climate Action)
