At only 8 square miles, Nauru uses a lot of bottles, mostly for drinking water – 20,000 per month (according to the Nauru Country Study Guide by Ibp USA). That’s 240,000 bottles a year. According to the same study, about 10% of the bottles are used to sell water or iced coffee in a localized recycling effort. So, in the spirit of Nauru, if you have some extra plastic bottles or tubs (yes, tubs) laying around, feel free to fill them up with coffee.
