SDG 12.2.3 Policy waste disposal – hazardous materials

NCUE has established the ‘Guidelines for Disposal of Laboratory Waste at National Changhua University of Education’. Liquid Waste, waste chemicals, and empty containers generated by laboratories across the University are collected and transported twice a year, while biomedical waste generated by the health center and laboratories is collected and transported once a week, as shown in Figures 1, Figures 2 and 3.

Please refer to the Center of Protection and Occupational Safety and Health's laboratory waste management website: https://saftyweb.ncue.edu.tw/var/file/10/1010/img/1027/675906012.pdf
