Inorganoc Waste treatment 

     National Chiayi University has established a comprehensive inorganic waste treatment and recycling system that ensures 100% of all inorganic waste is properly treated or reused. The process integrates on-campus classification, certified recycling, and external collaboration for specialized recovery.

• Collection and Initial Classification:

Recycling bins are placed throughout each building and campus area for collecting various inorganic wastes, including scrap iron, tin cans, aluminum and stainless-steel materials, PET bottles, glass, waste lighting illuminants, cables, batteries, electronic waste, and unrepairable bicycles. Cleaning staff collect waste daily from each point and transport it to the recycling field, where further manual sorting ensures recyclables are properly classified.

• Resource Recovery and Reuse:

Government-certified recycling vendors visit monthly to weigh and purchase sorted inorganic waste. The recyclers then process these materials and resell them to manufacturing factories for remanufacturing. Reusable construction materials (soil, gravel, and concrete) are repurposed in campus maintenance projects. The revenue generated from recycling is allocated to the Environmental Improvement Fund, which supports campus environmental enhancement and climate adaptation infrastructure.

• Furniture Repair and Reuse:

Damaged furniture, such as tables, chairs, and equipment, is repaired by the Discarded Furniture Recycling Plant and Creative Design Studio. Usable items are refurbished and auctioned publicly or redistributed to departments in need. Outdated computers from the IT department are also reallocated within the university to promote the 3R principle — Reduce, Reuse, Recycle.

• Electronic Waste Management:

For electronic waste containing precious metals, rare earth elements, and batteries, NCYU follows government recycling regulations and cooperates with the Environmental Resource Center at National Cheng Kung University (NCKU) to ensure proper recovery and material reclamation. Moreover, NCYU organizes annual environmental seminars to raise awareness among students, staff, and citizens about e-waste recycling and resource conservation.

     Through these integrated measures, 100% of all inorganic waste at National Chiayi University is properly treated or recycled, ensuring complete traceability, full regulatory compliance, and advancing the university’s commitment to SDG 12 (Responsible Consumption and Production) and SDG 11 (Sustainable Cities and Communities).
