The Total Volume of Inorganic Waste Treated
| Types of Waste | Amount (tons) | ||
| Total | Reused | Recycled | |
| – soft plastic, foam, etc. | 512 | – | – |
| – hard plastic, hard paper and glass | 9.65 | – | 9.2 |
| – printed paper | 10.8 | 5.5 | 6.1 |
| Total | 532.45 | 5.5 | 15.3 |
Description:
Inorganic waste was generated across all university campuses by various stakeholders, including staff, students, and food stall operators. The majority of this waste consisted of soft plastics and foam (512 tons), which are primarily handled by municipal waste services, as previously noted.
The table above presents the portion of inorganic, non-toxic waste that the university has managed through reuse and recycling initiatives. Out of a total of 532.45 tons of inorganic waste, 5.5 tons of printed paper were reused, while 15.3 tons were recycled—comprising 6.1 tons of printed paper and 9.2 tons of hard plastic, hard paper, and glass.
In total, 20.8 tons of inorganic waste—equivalent to approximately 3.9% of all inorganic, non-toxic waste—were successfully treated through reuse and recycling efforts. This demonstrates the university’s ongoing commitment to reducing waste sent to landfills and promoting sustainable resource management practices.

Inorganic waste treatment
Description:
Rajamangala University of Technology Phra Nakhon has prioritized sustainable waste management practices, with a particular focus on reducing wastepaper usage. In response to environmental concerns, the university has introduced several initiatives aimed at minimizing paper consumption and fostering a more sustainable working culture. These include organized activities to encourage the reuse of one-sided printed paper, which are actively practiced by both students and staff. This initiative has helped cultivate greater environmental awareness and responsibility within the campus community.
In addition to paper reduction efforts, the university has implemented a continuous campaign for sorting and recycling specific types of inorganic waste. Plastic bottles, metal cans, hard paper, and glass are separated at source and collected by local recycling services for proper treatment. This approach not only reduces the amount of waste sent to landfills but also supports broader environmental objectives, including resource conservation and waste minimization.
As a result of these combined efforts, the university successfully treated 20.8 tons of inorganic waste—comprising 5.5 tons of reused printed paper and 15.3 tons of recycled materials—which represents approximately 3.9% of the total 532.45 tons of inorganic, non-toxic waste generated. While this marks meaningful progress, the university remains committed to expanding its recycling programs, enhancing awareness campaigns, and improving waste sorting infrastructure to further reduce its environmental footprint in the coming years..

Total volume of Toxic Waste produced this year
Toxic waste: lab chemicals and oils, electronic equipment, and batteries.
| Types of Waste | This year amount (tons) | Last year amount (tons) | Increase (tons) |
| – electronics | 0.7 | 0.61 | 0.09 |
| – lab chemicals | 0.96 | 0.94 | 0.02 |
| – batteries | 0.22 | 0.18 | 0.04 |
| Total | 1.88 | 1.73 | 0.15 |
Description:
The table presents the total amount of toxic waste generated by Rajamangala University of Technology Phra Nakhon during the current reporting year, compiled as a combined figure from all campuses. This toxic waste primarily consists of laboratory chemicals, discarded electronic equipment, and used batteries, which require careful handling and disposal to prevent environmental and health risks.
In total, the university produced 1.88 tons of toxic waste this year, reflecting a slight increase from 1.73 tons last year. This rise is attributed to expanded academic and research activities across the university, which resulted in greater use of laboratory chemicals (0.96 tons), increased disposal of electronic equipment (0.7 tons), and higher volumes of used batteries (0.22 tons). All hazardous materials are stored securely and managed in accordance with environmental safety regulations.
The university remains committed to improving its hazardous waste management system, including upgrading storage facilities, strengthening partnerships with certified disposal companies, and implementing strategies to reduce the generation of toxic waste as university activities continue to grow.
