Since the use of Pesticides and Herbicides is not permitted within the campus and toxic E-waste, the primary sources of toxic waste at National Chiayi University come from chemical properties (including heavy metals), solvents and hazardous biological waste from laboratory experiments. Regarding radiation sources, National Chiayi University has a total of 7 X-ray machines used for teaching and research purposes. All of them are inspected and maintained annually and decommissioned in accordance with the regulations of the Atomic Energy Council (AEC).
The Treatment of toxic waste at NCYU described as follows:
NCYU's policy on Toxic Waste Collection/Removal is in line with national and international standards.
Submitted a waste removal plan to local authorities.
Regular Audits: Each semester, we undergo inspections from the Municipal Environmental Protection Bureau as well as internal control audits within the University.
Emergency Response Plans: Establish an emergency notification procedure to promptly address toxic material/waste incidents when they occur.
Chemical Substances Management Committee" (TCCSMS) holds quarterly meetings to review the purchase and disposal of hazardous substances.
Waste Collection & Storage:
Waste generated by units/labs is collected, labeled, and stored specific containers, the liquid stored in 20-liter HDPE containers.
Strict adherence to the "CHEMICAL COMPATIBILITY CHART" ensures no harmful chemical reactions.
Waste liquids are classified into six inorganic and three organic types.
Transportation & Notification:
When liquid waste barrels are 80% full, the Environmental Protection and Safety Management Center is informed.
Trained technicians then move these barrels to a temporary storage site.
The University allocates $7,000 USD annually to send toxic waste to the government-approved professional processing unit, our partner institutions “Environmental Resource Treatment Center” at National Cheng Kung University, where various toxic waste are processed according to unified standards. The technicians annually attend technical enhancement education, training and seminars at the Environmental Resource Treatment Center.
Chemical Resource Management:
We have established a chemical sharing platform that allows faculty members within the university to access small amounts of research chemicals, reducing instances of repetitive purchases. All chemical transfers comply with legal protocols.
Laboratories with toxic chemicals are required to report their usage online every quarter to achieve total quantity control.
Chemical waste is collected and stored temporarily. Every academic year, all waste will be properly packaged by trained technians and then transported to Environmental Resource Management Center at NCKU for furthure treatment.
Monitoring & Documentation:
Transport vehicles for toxic waste are GPS-enabled, ensuring real-time monitoring.
Online submissions to the Environmental Protection Bureau document all movements and details.
Disposal documentation is maintained for verification purposes.
Hazardous biological waste from laboratory experiments:
The treatment of biotoxic waste is governed by the Biosafety Committee. The primary focus is on pretreatment prior to disposal. The primary toxic waste in the University comes from experimental microorganisms and cells. As per the guidelines, they must undergo high-temperature sterilization in an autoclave to ensure the complete elimination of microorganisms before being disposed of according to waste treatment guidelines.
Oversight & Training:
NCYU's "Toxic and Concerned Chemical Substances Management Committee" (TCCSMS) oversees all hazardous substances management.
Quarterly meetings ensure strict adherence to protocols.
The Environmental Protection and Safety Management Center provides regular training sessions on toxic substance handling.
All toxic substance transportation and quantities are publicly announced on the website.
