Crystal-clear water, in every ocean, from every tap. That’s Dopper’s goal. Our nemesis? Single-use water bottles. That’s why we created the ultimate reusable water bottle, called Dopper. This bottle battles the throwaway lifestyle. And it is working. Up until now, we’ve prevented over 40 million kilos of single-use plastic from entering our oceans. Feels pretty good. But when you realise that we throw a garbage truck of plastic waste in our oceans every minute, we still have a long way to go. Luckily, we’re not doing this alone. We believe that we need the next generation of changemakers – yes you! – to change the world. That’s why we started a competition: the Dopper Changemaker Challenge.


Thesis award with a goal

We all know the recipe for plastic soup. Just add over 9 billion kilos of plastic waste to the ocean every year. Stir a little. Done! More plastic than fish by 2050. We don’t like those numbers. With the Dopper Changemaker Challenge we started our own thesis award to accelerate the development of solutions that have a big impact on the plastic and water issues.


Hello. Is it you we’re looking for?

Probably YES. We need the help of every student, University or other higher vocational education, Bachelor or Master, from Product Design to Biology, from Marketing to Economics. It doesn’t even matter if you just started brainstorming for ideas or already finished your graduation project or thesis. As long as your graduation evolves around clean water and/or plastic waste and you live in either the Netherlands, Belgium, Germany, the UK or Nepal. Not sure if you can join? Let’s check!

Your project is about clean water and/or plastic waste. You can find some examples here.

  • You are or were registered as a Bachelor or Master student at a university or other higher vocational education in Belgium, The Netherlands, Germany, Nepal or the United Kingdom;
  • You are still working on your graduation project or thesis, or finished it after 1 September 2018;
  • You determine(d) the subject of your project or thesis yourself;
  • You are available on 29 May 2019, and you can be personally present on 15 and 16 June 2019;
  • Are you writing your thesis for a company? No problem. Read the article about thesis embargos here.
  • You submitted your idea before 12 April 2019.

Still not sure? Feel free to contact us with your dilemma. We’re happy to help.


When you sign up for the Dopper Changemaker Challenge you (and your graduation project) stand a chance to get featured in the media, be invited on stage, get useful network introductions and win a research grant up to £5,000. This way, we hope you can make your project ground-breaking. How about using the funding to build a prototype, or for a trip to that prestigious research facility? Or for starting a crowdfunding campaign? This challenge is only the beginning!


Global thesis award. In four countries.

The Dopper Changemaker Challenge started in the Netherlands in 2017, but this year we are going global! We’re coming to Amsterdam (for Dutch and Belgian students), Berlin, London and Kathmandu. This doesn’t mean you have to live or study in those cities, as long as you live in one of the participating countries, you’re fine. You might have to travel to the capital for participation though.


Our partner in crime

Dopper’s vision of a world without plastic waste in our waters is ambitious. In order to be as effective as possible in reaching our goal, we are always eager to partner up with other organisations that share this vision. Wherever, whenever.

For the execution of the Dopper Changemaker Challenge we partnered up with Impacthub. This has organisation with offices all over the world: in more than 50 countries and in over 100 locations! To us though, it is simply our star when it comes the needed boots on the ground in the United Kingdom, Germany, and the Netherlands. Like Dopper, Impacthub is a mission driven organisation. Theirs being a bit broader namely: promoting the Sustainable Development Goals (SDGs) through their various projects.

Impacthub London Kings Cross

If Britannia truly rules the waves, we shouldn’t have to look any further for the plastic soup. Fortunately, our friends at Impacthub London Kings Cross are helping us to mobilise the students from England, Scotland, Wales, and Northern Ireland. Aside from the Dopper Changemaker Challenge this partner of ours has experience with projects such as: Feeding the City, the Social Challenges Innovation Platform, Benisi: scaling social innovation, Plastic Fantastic Challenge.
