The Current Financial System
The present system at schools in Indonesia involves students purchasing approximately 2 aqua-cups per day from the canteen for 5 cents per cup. There are 241 effective school days per year, costing students $14,460 to obtain 72,300 Liters of water per year. The profits from the sale of aqua cups go to the canteen. The environment club at the school collects used aqua cups and sells them to scavengers for 30 cents per kg. This gives the environment club a total income of less than $300 per year.
Lifecycle of an Aquacup
Both the safe disposal (throwing in the bin) and the unsafe disposal (throwing on the ground or burning) of aquacups has serious environmental consequences. As plastic never fully degrades, regardless of their disposal they will eventually break down into smaller and smaller pieces that become super absorbent of toxins present in their surrounding environment. These toxic pellets are then ingested by micro-organisms and subsequently enter our food chains where they are passed on through the trophic levels until it is us humans that are consuming them. The aim of Bottle for Botol is to reduce the consumption of plastics and increase awareness of this plastic problem.
Bottle for Botol Cycle
The current system has extreme environmental consequences amounting from the disposal, both safe and unsafe, of Aqua cups. The new system involves using larger 19 Liter refillable plastic bottles that the children can then use to fill up their stainless steel water bottles. One of these will be fitted in every classroom thus eliminating the need to sell aqua cups.
Bottle for Botol financial system
The current system costs students a total of $14,460 per year to drink clean water at school, not including environmental costs. After set-up, this system will cost $3,805 for the same number of liters of water. All extra money will go towards purchasing new water bottles for the incoming year of students, increasing profits for the canteen and environment club in addition to decreasing the cost of water for all students.
