All of us appreciate a bottle of fresh water. But once consumed, what happens to all that plastic bottles? The fact is that 80% of plastic in our oceans is from land sources. So where is it coming from?

Every minute, one million plastic bottles are bought in the world, and this amount is projected to grow by another 20% by 2021, amounting to 583.3bn bottles, as projected by latest Euromonitor International’s global packaging trends reports.

The majority of plastic bottles used across the globe are for drinking water, according to Rosemary Downey, head of packaging at Euromonitor and one of the world’s experts in plastic bottle production.

Most plastic bottles used for soft drinks and water are made from a petroleum product polyethylene terephthalate (PET), requiring yearly 17 million barrels of oil to produce and distribute – the equivalent of some million cars tanks. While PET is highly recyclable, the amounts of recycled bottles around the world fail to prevent them from polluting the oceans.

Education is one of the main drivers of change when it comes to spread the word about the impact of bottled water on our environment and encourage the sustainable practices such as recycling and using grid-connected water dispensers.

Early 2019, Droople collaborated with the EPFL (Swiss Federal School of Technology) through the installation of their Droople Smart Filtration Solution on water dispensers at the university campus. The solution features Droople Smart Flow (IoT Smart device that measures and transmits flow and temperature data) combined with Droople Water Intelligence Platform.

The data gathered over five weeks revealed that the yearly affluence to one water fountain amounts to roughly 48’000 users, with a yearly water usage of about 12’000 liters. The use of one water dispenser is therefore contributing to avoiding the production of some 24’000 plastic bottles a year!

The evidence shows that fountains on a busy university campus are mainly used over lunch, when they are delivering water to students at full steam. As the risk of exceeding filter capacity is getting high, Droople technology allows for automating the maintenance frequency of the filtration system.

Thanks to fountainOS, as a company we can calculate the water consumption to best meet the customer's request. Water consumption is calculated so that the filter can be changed at the right time.

Smarter fountains in Switzerland

Impact for everyone! Outdoor equipment retailer, Urbanat, the City of Geneva and Fontaineo (manufacturer) collaborated to launch a campaign to beat the heat wave and reduce single-use water bottles.

Neuvecelle Project

Droople introduced the Droople for Schools solution in Neuvecelle's Robert Magnin School to promote hands hygiene and water conservation. Through a "hygiene score" algorithm, students were encouraged to handwashing, achieving scores close to the ideal. After two years of operations, the initiative led to a 22% annual reduction in the school's water consumption and provided insights for more efficient water usage strategies.
