Description:
The table displays the volume of inorganic waste generated by all university participants (staff, students, owners of food stands, etc.) on each campus. The overall amount of inorganic, non-toxic waste was 537.97 tons. Of all the campuses, North Bangkok Campus produced the highest amount (230.58 tons), followed by Phra Nakhon Commercial Campus (155.61 tons). The majority of inorganic, non-toxic waste produced was soft plastic, hard plastic, foam, glass, hard paper, and printed paper. Out of these, the amount of soft plastic and foam increased the most on North Bangkok Campus (226 tons) and then on Phra Nakhon Commercial Campus (150.36 tons). The least quantity of hard plastic, glass, and hard paper was produced on each campus, totaling 8.04 tons, whereas printed paper generated 14.16 tons.

Description:
Several types of inorganic waste were generated on each campus by university staff, students, owners of food stands, and so on. Foam, glass, hard paper, soft plastic, hard plastic, and printed paper made up the majority of the inorganic, non-toxic waste that was produced as mentioned previously. When it comes to treatment, the table above shows how much inorganic waste was managed. There were 537.97 tons of inorganic, non-toxic garbage in total. By this number, 5.42 tons of printed paper, especially one-sided printed paper, were reused, that is, 1.01% of the treatment. There were no reports on reusing other waste, such as soft paper, hard paper, hard plastic, glass, and foam. Also, there were no reports on the amount of inorganic waste recycled at all.

Sorted paper for reusing
(Rajamangala University of Technology Phra Nakhon, Thailand)
Description:
Rajamangala University of Technology Phra Nakhon has had concerns with wastepaper management. The university has organized several activities to support a working system with less paper. In this respect, the university achieved its goal by encouraging students and personnel to reuse one-sided printed paper. The treatment for this issue was successful (1.01%) as in 3.7. The university also runs a permanent campaign on using cloth bags and baskets instead of plastic bags. Even though it does not own a plastic and paper recycling center, it has an alternative way to treat inorganic waste systematically. For instance, the waste will be sorted and sold to local collectors.

| Types of Waste | Amount (tons) |
| Toxic | 0.87 |
| – electronics | 0.403 |
| – lab chemicals | 0.207 |
| – batteries | 0.26 |
Description:
As shown in the table above, it reveals that there are several types of toxic waste produced at Rajamangala University of Technology Phra Nakhon. The information gave evidence as a whole picture of the university, not as individual campuses. This toxic waste includes electronic equipment, laboratory chemicals, and batteries. Out of the total amount (0.87 tons), electronic waste was generated the most (0.403 tons). Furthermore, there was the production of the waste from batteries (0.26 tons) and the laboratory chemicals (0.207 tons).

- % treated = 0.107/0.87 * 100% = 12.30%
Description:
The table in the total volume of toxic waste treated, shows some information about the treatment of toxic waste at Rajamangala University of Technology Phra Nakhon. Overall, there were a total of 0.87 tons of toxic waste, including electronic equipment (0.403 tons), laboratory chemicals (0.207 tons), and batteries (0.26 tons). From the table, it was quite clear that, in terms of treatment, the waste from laboratory chemicals was dealt with to some extent by classifying and handing it over to a certified company (0.107 tons). Other waste (electronics and batteries) was sent to the city treatment center, but there was no process tracking. And that probably resulted in no reports at all.
