BottleChallenge

BottleChallenge League for companies

Get the whole company playing against the single-use bottle

Employees fill their bottles with tap water instead of buying bottled water. Departments compete for the score, the best get prizes you come up with yourselves, and the company has figures it can show clients, its bank and its auditor.

A team of 10 works straight away. When you want the whole company in and the data summaries for reports, write to us and we will switch them on for your team.

Sample data. An intranet graphic, straight from the company panel.

A choice made several times a day

Water from the vending machine, or a bottle filled in the kitchen? Everyone decides alone, usually on the way from one meeting to the next. BottleChallenge makes the bottle win more often at your company, because every bottle filled raises the whole team’s score.

After filling their bottle, an employee holds their phone to the BottleChallenge sticker by the tap or water cooler, and the app adds the bottle to the team’s score. Nobody types anything in or keeps watch. The table and the department ranking update themselves.

How to start

  1. 01

    You start the company team

    In the panel on the website, with your company name and logo. The team gets a code employees join with.

  2. 02

    Employees join with the code

    In the free app for iPhone and Android, in a few seconds. You can split them into departments or offices.

  3. 03

    Employees fill their bottles

    After filling up, they hold their phone to the BottleChallenge sticker at the place with water, in the office or elsewhere. If your office has no sticker yet, write to us.

  4. 04

    The game begins

    A season with a table, a department ranking, duels with other companies and prizes for the most active.

What the person running the team gets

Squad and departments

Who has joined, which department they belong to and how each department is doing.

Duels and tournaments

A challenge to another company for a set number of days, or a tournament of several teams with one table.

Prizes

A day off, lunch with the board, a donation to a cause the winners choose. You set the condition, and the app shows everyone how far they still have to go.

Data summaries

Figures for any period, ready to paste into a questionnaire, a report or a message to employees.

Data summaries

One source of figures for clients, reports and employees

A client sends a sustainability questionnaire, the bank asks about environmental practices, and the communications team wants to write a post. Based on the number of bottles filled, the panel prepares ready text for each of these occasions. You choose where the text is going, and the panel tells you which field to paste it into.

    VSME

    A description of the practice for B2, B7 and C2, with the B2 table laid out as in the European Commission’s recommendation.

  • Health and safety

B2 as text

Practices. Since 1 June 2026, we have run BottleChallenge League for our employees. In the period from 1 June to 30 September 2026, 132 employees took part. Of these, 104 filled a bottle at least once (43.3% of average headcount). In total, employees filled 2,912 bottles, 1,980 of them at our own sites.

Policies. [to be completed: whether the programme follows from an environmental policy]

Targets. Our target is 50% of employees active in the programme by 31 December 2026.

Sample data. A passage from the VSME tab. The yellow field is the one you complete.

Copy any passage with one button, or download the whole summary as PDF, DOCX or XLSX, in English or Polish.

Every summary can be checked

Every downloaded file has a number and a QR code. A client, a bank or an auditor opens the check page and sees the figures as the summary was issued, with its SHA-256 hash. When the figures for the same period change, a new summary replaces the old one, and the page says so.

Straight about what this is

The panel provides aggregated data and ready text, and your company writes the report. The summary is not a certificate and gives no kilograms of plastic or CO2, because the number of bottles filled is not a mass of waste. So it makes no claim you could not defend.

Employee privacy

Summaries are aggregated

Reports and downloaded files never hold data on individual people. Departments, sites and countries with fewer than five active people are merged into “other”.

Everyone joins on their own

Employees join from their own account and can leave at any time. The person running the team sees names and results in the League, but never e-mail addresses or where someone fills up.

Deleting an account

Employees can delete their account at any time. Their data disappear from the app and go into no later summary. Summaries issued earlier contain aggregated figures only.

What companies ask us

Do employees have to install an app?

Yes. After filling their bottle, the employee holds their phone to the BottleChallenge sticker, and the app adds the bottle to the team’s score. The app is free on iPhone and Android, and joining the team takes a few seconds.

What about people who work remotely or on the road?

We count bottles filled at any place with a BottleChallenge sticker, including outside the office. The summary shows separately how many bottles were filled at your own sites.

Won’t people get bored after a month?

The game runs in seasons, and the table starts from zero every season. On top of that come duels with other companies, tournaments and prizes you set yourselves.

Can we put the panel’s figures in our report?

Yes, that is what they are for. Every tab tells you where in the report the text goes, and the indicator dictionary and the method are in every downloaded file. The company is responsible for what its report says.

Where should a large company start?

With one department or office. Once you see how it works, we extend the team to the whole company and switch on the data summaries.

Start with one department

You can set up the team in a few minutes, and the first bottle filled can be on the table today. If you would rather talk first, write to us.
