Toxic Waste Treatment
Description:
As reported in Section 3.15, Rajamangala University of Technology Phra Nakhon generated a total of 1.81 tons of toxic waste during the current reporting year. The toxic waste included discarded electronic equipment, laboratory chemicals and oils, and used batteries.
The university manages toxic waste through proper classification, secure temporary storage, and transfer to appropriate treatment channels. Laboratory chemical waste is classified and prepared for treatment by a certified hazardous-waste company. In this reporting year, Recycle Engineering Co., Ltd. was selected as the certified company responsible for handling and treating the university’s hazardous chemical waste.
A total of 1.19 tons of toxic waste were classified and treated, representing approximately 65.75% of the total toxic waste generated. This treated amount consisted mainly of 0.89 tons of laboratory chemicals and 0.30 tons of electronic waste. Laboratory chemicals formed the largest treated category and were managed through certified treatment and disposal procedures.
Used batteries were included in the university’s toxic-waste inventory; however, no treated amount was recorded for this category in the current reporting year. The university will continue to strengthen battery-waste collection and treatment in future implementation.
Overall, the toxic-waste treatment process demonstrates the university’s commitment to environmental safety, pollution prevention, and responsible hazardous-waste management. The use of a certified hazardous-waste company helps ensure that toxic materials are handled, transported, treated, and disposed of through proper and safe procedures.

Sewage disposal
Preliminary sewage treatment (Rajamangala University of Technology Phra Nakhon, Thailand)
Description:
Rajamangala University of Technology Phra Nakhon recognizes the importance of proper sewage and wastewater management in reducing environmental impacts and protecting the health and well-being of students, staff, and surrounding communities. Wastewater generated on campus mainly comes from restroom facilities, cafeteria operations, instructional kitchens, and other academic and administrative activities.
This year, the university continued to implement a preliminary sewage-treatment system before wastewater is discharged into the municipal sewage network. The system is designed to reduce pollution load, remove
grease and food residues, and support initial biological treatment of wastewater generated from campus activities.
The university’s preliminary sewage-treatment practices include the following components:
- Rotating disc wastewater treatment
This system supports biological treatment by using rotating discs that allow microorganisms to grow and break down organic matter in wastewater. - Aerated wastewater treatment
Air is introduced into wastewater to support aerobic microorganisms in decomposing organic pollutants and improving wastewater quality before discharge. - Grease traps and food-waste filters
These devices are used in cafeteria and kitchen areas to capture fats, oils, grease, and food particles before they enter the drainage system. This helps prevent pipe blockage and reduces contamination in wastewater.
After preliminary treatment, wastewater from the university is discharged into the municipal sewage system for further treatment and final disposal. This approach ensures that campus wastewater is managed through both on-site preliminary treatment and the city’s wastewater-management infrastructure.
Overall, the university’s sewage-disposal practice reflects its continued commitment to responsible wastewater management, pollution reduction, and environmental protection. The university will continue to maintain and improve its preliminary treatment systems, especially in areas with high wastewater generation such as cafeterias, instructional kitchens, and restroom facilities.

Impact of Waste Management programs in supporting the SDGs
Description:
Rajamangala University of Technology Phra Nakhon (RMUTP) implements Waste Management (WS) programs that support sustainable development through waste reduction, reuse, recycling, toxic-waste treatment, organic-waste treatment, inorganic-waste treatment, and preliminary sewage management.
Based on the UI GreenMetric 2026 guideline, the Waste (WS) category is linked to 7 Sustainable Development Goals: SDG 3 Good Health and Well-Being, SDG 6 Clean Water and Sanitation, SDG 11 Sustainable Cities and Communities, SDG 12 Responsible Consumption and Production, SDG 14 Life Below Water, SDG 15 Life on Land, and SDG 17 Partnerships for the Goals.
This year, RMUTP’s waste-management activities included 3R implementation, reduction of paper and plastic use, reuse of food waste as animal feed, recycling of inorganic waste, treatment of toxic waste through certified channels, and preliminary sewage treatment before discharge to the municipal system. These activities help reduce pollution, improve campus sanitation, support resource recovery, and promote responsible consumption among students, staff, food stall operators, and campus users.
Therefore, RMUTP reports that its Waste Management programs support 7 SDGs, corresponding to Significant impact under the UI GreenMetric assessment scale.
