Implementation of SDGs 15


15. Life On Land

15.4. Land sensitive waste disposal
15.4.1. Water discharge guidelines and standards

Residual water from AC is contained inside gallons. This residual water will be reused for watering plants, radiator water, and cleaning toilets. There are several reasons why we chose these methods for reusing the residual water:

  • Watering plants: residual water from AC has a very low to almost no minerals, just like distilled water but not as clean. This kind of water could be reused to water plants that cannot tolerate mineral water, such as carnivorous plants. Carnivorous plants are also known to have a bad reaction towards chlorine that is usually found in the faucet water, but cannot be found in residual water from AC.
  • Radiator water: rather than mineral water, it is better to use residual water from AC as radiator water because it can help the radiator to maintain cold temperature and keep the engine in good condition. Thus, it will indirectly decrease expenses for car services. Using the residual water from AC for radiator water could be changed every two months.
  • Cleaning toilets: there are some elements inside the residual water from AC that could help remove stubborn yellow stains in the toilet. It could be used by pouring the residual water to the toilet and let it sit for a night, then in the morning scrub it like usual. This will help to make the toilets appear cleaner as well as kill the bacteria inside the toilet.

Other liquid waste at the Faculty of Psychology is disposed through a concrete septic tank to prevent any leakage into the ground.

15.4.2. Policy on plastic waste reduction

Since 2019, both staff and students in the Faculty of Psychology are requested to use reusable items, like tumblers and tote bags or cloth bags. By using reusable items, we can reduce plastic use and plastic waste we produce in the Faculty of Psychology. Moreover, in the Faculty of Psychology, we have two drinkable-water fountains that all people who visit our faculty could use to refill their tumbler.

15.4.3. Policy on hazardous waste disposal

In the Faculty of Psychology, potentially hazardous wastes, like glasses, lamps, batteries, etc., will be collected and grouped accordingly. In this way, the hazardous waste could be processed appropriately and minimized the impact it caused to the environment because of the inappropriate waste treatment.
