SI 2.2 Implementation of Waste Management Systems
[SI 2.2.2] Toxic waste treatment

| Toxic Waste Treatment (Siam University, Thailand) |
Description:
Siam University is concern with toxic waste management from various laboratories in the campus since toxic waste is serious problems for environment and wellbeing of lives on earth. “Waste Technical Team” was appointed to be responsible for the management of hazardous (solid/liquid/gaseous) waste. Siam University has set policy and practices regarding the disposal of hazardous materials waste and also is a member of Laboratory Safety Network. Since October 2020, our faculty members from the Faculty of Science participated actively in their annual training, “Safety Lab and Safety Culture for Sustainability”. It is our policy that all faculties that provide chemical laboratories as well as toxic substances set up the schedule of chemical waste management in each classroom. The chemical waste substances are separated into non-toxic and toxic waste. Some non-toxic waste (e.g., acid, base and ethanol) is pretreated and reused in the lab. We also have used the chemical substances as necessary and tried to minimize amount of toxic waste during study and research in the campus. However, all toxic wastes classified and separately collected in prepared tanks or bottles are safely stored in a particular cabinet. Afterward, all of toxic wastes (100%) are managed and disposed by an authorized company.

Type of Toxic Waste (Treated) |
Year 2023 Amount (Tons) |
Year 2024 Amount (Tons) |
|---|---|---|
| Acid Waste | 10.418 | 10.001 |
| Alkaline Waste | 10.364 | 9.999 |
| Miscellaneous Aqueous Waste | 1.022 | 0.881 |
| Oxidizing Waste | 2.042 | 1.982 |
| Total | 23.846 | 22.638 |
Description:
Almost non-toxic waste (e.g., acid, base and ethanol) is reused in the laboratories and some (around 21 tons/year) are pretreated prior to drainage. While, all toxic wastes that are classified and separately collected in prepared tanks or bottles are managed and disposed by an authorized company. Therefore, amount of total toxic waste treated in 2024 was more than 90%.
Amount of toxic waste (metric ton) treated in 2024 = 22.638 tons
Amount of toxic waste (metric ton) treated in 2023 = 23.846 tons
