Plastic pollution is threatening not only the terrestrial ecosystem but also the marine ecosystem worldwide. ITS as higher education is aware of the importance of plastic waste reduction to protect the environment. The initiatives to reduce plastic waste on campus are supported by the Circular Letter of ITS Rector No. T-95007-IT2-TU.00.08-2019 about ITS’ Initiatives towards Sustainable and Environmental Friendly Campus, specifically item A no. 6-8 (to encourage waste management on campus through reducing, reuse, and recycling). ITS also issues the Circular Letter regarding the use of disposable drinking water/bottled water and plastic bags at ITS Campus. To reduce the use of bottled water, ITS promotes the initiative to bring its own water bottle. In every meeting, ITS does not provide plastic bottled water, instead, ITS prepares the water dispenser and glasses.
