The Total volume of Inorganic Waste produced this year
Description:
The table presents the total volume of inorganic, non-toxic waste generated across the five campuses of Rajamangala University of Technology Phra Nakhon during the current reporting year. The waste was generated by staff, students, food stall operators, and other campus users. Inorganic waste in this report includes soft plastic and foam collected from dumpsters, mixed recyclable materials such as hard plastic, cans, glass, and hard paper, as well as printed paper waste.
This year, the university recorded a total of 505.95 tons of inorganic waste, compared with 532.45 tons last year. This represents an overall decrease of 26.5 tons, or approximately 4.98%.
Among the five campuses, North Bangkok Campus generated the highest amount of inorganic waste at 230.12 tons, followed by Phra Nakhon Commercial Campus at 141.03 tons, Thewet Campus at 85.25 tons, Chotiwet Campus at 48.80 tons, and Chom Thong Campus at 0.75 tons.
Soft plastic, foam, and related waste collected from dumpsters remained the dominant component, amounting to 480 tons. This decreased by 32 tons from last year’s 512 tons, reflecting the university’s continued efforts to reduce disposable plastic and foam waste.
In contrast, the recorded amount of mixed recyclable materials, including hard plastic, cans, glass, and hard paper, increased from 9.65 tons to 13.95 tons. Printed paper waste also increased from 10.8 tons to 12.0 tons. These increases are mainly attributed to more effective data collection, improved waste classification, and better recording of separated recyclable and paper waste across campuses, rather than a direct increase in uncontrolled waste generation.
Overall, the data show that total inorganic waste decreased, while some subcategories increased due to improved monitoring and data collection. This reflects the university’s ongoing efforts to strengthen
waste-management practices through waste reduction, better waste separation, recycling support, and more systematic reporting across all campuses.

The Total Volume of Inorganic Waste Treated
Description:
The table presents the total volume of inorganic waste treated by Rajamangala University of Technology Phra Nakhon during the current reporting year. The treatment methods include reuse and recycling of selected inorganic waste materials, particularly recyclable materials and printed paper.
This year, the university generated a total of 505.95 tons of inorganic waste. Of this amount, 5.8 tons were reused and 18.5 tons were recycled, giving a total treated volume of 24.3 tons. This represents approximately 4.8% of the total inorganic waste generated.
Soft plastic, foam, and related waste collected from dumpsters accounted for the largest portion of inorganic waste at 480 tons. However, no reused or recycled amount was recorded for this category, as most of this waste was mixed waste handled through the regular waste-collection system.
For recyclable inorganic materials, including hard plastic, cans, glass, and hard paper, 13.3 tons out of 13.95 tons were recycled. In addition, printed paper waste totaled 12 tons, of which 5.8 tons were reused and 5.2 tons were recycled.
Overall, the table shows that the university’s inorganic-waste treatment currently focuses mainly on recyclable materials and printed paper. Although the total treated proportion remains limited because soft plastic and foam dominate the inorganic-waste stream, the reuse and recycling of separated materials reflects the university’s continued efforts to improve waste separation, resource recovery, and sustainable waste-management practices.

Inorganic waste treatment
Description:
As reported in Section 3.11, Rajamangala University of Technology Phra Nakhon generated a total of 505.95 tons of inorganic waste during the current reporting year. The university treated selected inorganic waste through reuse and recycling practices, particularly for separated recyclable materials and printed paper.
A total of 24.3 tons of inorganic waste were treated this year, consisting of 5.8 tons reused and 18.5 tons recycled. This represents approximately 4.8% of the total inorganic waste generated across the university.
The main recycled materials were hard plastic, cans, glass, and hard paper, with 13.3 tons recycled from a total of 13.95 tons in this category. Printed paper waste was also treated through both reuse and recycling. Of the 12 tons of printed paper waste generated this year, 5.8 tons were reused and 5.2 tons were recycled.
Soft plastic, foam, and related mixed waste collected from dumpsters accounted for the largest portion of inorganic waste, amounting to 480 tons. However, no reused or recycled amount was recorded for this category because most of this waste was mixed and handled through the regular waste-collection system.
Overall, the university’s inorganic-waste treatment currently focuses on separated recyclable materials and printed paper. Although the total treatment proportion remains limited due to the large volume of mixed soft plastic and foam waste, the reuse and recycling activities demonstrate the university’s continued effort to improve waste separation, resource recovery, and sustainable inorganic-waste management.
