You're at the airport. A bottle of water costs what it always does. You open the app and see a café fifty metres away where you can refill your bottle for free. You go, tap your phone against the tag, and leave with water and points towards your next cinema ticket.

The app is free, ad-free, and has no hidden charges. The network covers over 57,000 points across 95 countries and works offline. Wherever you go, the map goes with you.

Over time, you stop thinking about whether to buy a bottle. You simply don't buy one. A habit is simpler than a decision.

If you find a public drinking fountain that isn't on the map yet, you can add it. You earn points for it, and the map becomes a little bit yours.

Someone walks in and asks for tap water for their bottle. You give it to them. They leave. Nothing special.

But several things just happened at once. The app logged a record: your venue, today, 11:43. Your profile on the map now shows that this month, your guests avoided 340 plastic bottles. You can publish that tomorrow. Nobody can question it, because every single scan stands behind it.

Your venue is visible on the map searched by tens of thousands of active users looking for the nearest refill point. Every person who comes in for water is a potential new customer. Many stay for coffee.

The NFC tag and a door sticker are provided free of charge and sent directly to you. Registration takes a few minutes. Staff don't need to do anything. The guest asks, gets the water, scans the tag themselves.

A user has refilled their bottle fifty times. They have enough EcoDrops for a ticket. They choose your museum, theatre, or opera. Not because they saw an ad. Because they earned it, and they want to claim their reward somewhere worth their while.

They arrive motivated. And they come back.

You decide how many tickets you offer, in what form, and on what terms. Your institution appears in the app as a place people can reach through their environmental choices. That attracts people who care about substance, not statements.

End of quarter. Someone opens the ESG dashboard. The environmental data is already there: refills, kilograms of plastic that never reached the environment, CO₂ saved. Export, paste. No estimates. No consultants. Behind every entry stands a specific NFC event with geolocation, recorded on a public blockchain.

What happened between the start and end of that quarter? Employees drank water. Just like always. Except instead of buying plastic bottles, they refilled their reusable bottles at cafés and fountains. Every time, they earned points for tickets and discounts. The company watched it in real time.

Internal leaderboards, daily streaks, team challenges: the conversation stays alive all year, not just on Earth Day. And habits formed at work travel home. The employee who refills their bottle at the office starts doing it at weekends, with their family, on the road.

For companies subject to CSRD, Teams data maps directly to ESRS E5 and GRI indicators and is audit-ready. For HR, it's an environmental programme that runs every single day without events or coordinators. For employer branding, it's a statement no competitor can make without the same data: "Our team prevented X kilograms of plastic this year. Every event is verified and recorded on a public blockchain."

Employees join with a single invitation code. The company sees aggregated data. Privacy preserved.

The fountain has been standing in the park for years. You know it works. You don't know whether anyone uses it.

When a fountain joins the BottleChallenge map, it starts talking. Every refill leaves a trace: time, location, a counter. By the end of the month, you have data no other system has ever given you: which fountains are being used, at what times, in which neighbourhoods people are choosing tap water over plastic.

That's data for an environmental report, for conversations with the city about new infrastructure, for communication with residents. It's also a direct response to the requirements of the revised EU Drinking Water Directive, which obliges operators to actively promote consumption of tap water and document the actions they take.

The NFC tag is self-adhesive. Nothing to install. Nothing to alter.

An official sits down to write a funding application. The programme requires indicators: how many residents are choosing alternatives to single-use plastic, where, how often, how that changes over time. This is usually where estimates appear, the kind an auditor will question.

A city partnered with BottleChallenge has hard data. Every refill at a municipal fountain or partner café is recorded with exact location and time. Monthly reports are generated automatically. The data is verifiable, public, and ready.

The same applies to climate reports, plastic reduction strategies, and compliance with the Single-Use Plastics Directive. BottleChallenge doesn't replace urban policy. It provides the data that allows cities to implement that policy and prove it works.

Joining is free. We discuss the form of partnership that fits each city's needs and circumstances.

Your customer buys a water bottle. On the packaging is a QR code. They scan it in the shop or at home that evening. They download the app. They see a map with 57,000 refill points across 95 countries.

A week later they're on holiday in Barcelona. They open the app and find a point 200 metres from their hotel. Your product is with them. Your brand is there, where you have no shop, no campaign, no presence.

Without BottleChallenge, it's a container. With it, it's a key to a global refill infrastructure, a rewards system, and a community of people who have consciously chosen to leave single-use plastic behind. That changes the product category, and gives you an advantage at the shelf that no competitor can offer today.

Every product leaving your factory becomes a water bottle its owner can refill for free across 95 countries. Not every bottle on the shelf can say that. Yours can.

You receive a dedicated QR code with source tracking, ready-made co-branding materials, and regular impact reports: refills, plastic avoided, CO₂ reduced. You can also create a brand team in the app that customers join voluntarily and keep coming back to.

Retailers and chains. A customer buys a water bottle and joins the store's team in the app. They refill it once, then again, and then it's a habit. The store becomes part of their daily life, not just a one-time transaction.

A student walks past the vending machine in the school corridor. She fills her bottle at the water fountain instead. She taps her phone. Points land. Somewhere on the school dashboard, a counter moves up by one.

By the end of term, that counter has something to say. How many bottles did this school avoid this year? How does that compare to last year? The data is already there, for an annual report, for a school assembly, and for a conversation about what small daily choices actually add up to.
