waste sorting
At our university, we promote waste reduction and recycling to lessen our environmental impact and simultaneously lower waste disposal costs by sorting waste. Waste sorting at the university differs from that in typical households. Please refer to the "Alphabetical Waste Sorting Guide" for details.

Q.If sauce or other condiments get on a plastic lunchbox container, should I wash it or wipe it with a tissue?
A.
Plastic containers are incinerated as industrial waste, so you can leave them as they are. In fact, washing them or wiping them with tissue paper will increase the load on the sewage system and the amount of waste generated.
Q.Should I wash the inside of bottles and cans?
A.
For beverages, there's no need to wash them once you've finished drinking. If there's a lot of sticky residue, wipe it off with a tissue, and then dispose of the tissue with your regular food waste.
Q.The candy tin is too big to fit in the "bottles and cans" category.
A.
Please remove the lid from the "bottles and cans" trash can and place your items inside. For items that do not fit, please contact the relevant department as indicated in the remarks section.
