• The U.S. manufactures 2.6 tons of plastic for water bottles

• For students who do not regularly use reusable water bottles, they purchase 6 bottles and average them

• As the water temperature rises (eg, behind a hot car), these chemicals may become intensified when immersed in water.

Refillable water bottle station designed by Elkay is effectively replenished with reusable water bottle by its design. These places will produce more water

These stations can be installed indoors or outdoors because faster than a fountain and their touchless sensors are more hygienic.

Make them easy to access. Elkay has several different models, some of which are specially designed to supplement only reusable models.

Feasibility This project is an easy step for universities to reduce the health of PET bottles water, students, teachers, staff, which is harmful to the environment, and help college people save money. By adding some machines, you can measure the students' uses and interests and take further steps.

Place a different amount of water in about 10 bottles of water bottles. Lay them from the most complete to the shortest, then order the bottoms (1-10) of each bottle in order from the heaviest to the lightest ("10" to the water bottle, the minimum moisture The bottle is "1" by content). Fold the group blindly (about 10 people) and line up. Place a bottle of water randomly in front of everyone. Then the team is asked to drop the bottles of water in the order of weight with the heaviest bottle on the left side and the lightest bottle on the right side. When you think they are right, remove the blind folds and check the number of bottle bottoms to see if they are correct.

Annual bottling capacity is 89 billion liters of water, producing about 1.5 million tons of plastic (3). Bottled drinking water on the market - Converting PET bottles of bottled bottles into drinking water - Transporting bottled water and refrigerating - the required amount of oil to 25% of the volume of the bottle It means equivalent. In the case of 250 million liters of water, this is equivalent to 50 million liters of oil - 314,465 barrels of oil. In addition to mineral water, twice the amount of water is used in the manufacturing process. The volume of water sold per liter is equivalent to 3 liters of water (4). Shipping costs are another big negative externalities. Transportation costs are huge because we transport bottled water from suppliers to bottling, bottlers to consumers, and from the perspective of currency and the environment worldwide.
