Merijn Everaarts:

CEO and Founder of Dopper

The inspiration to become a social entrepreneur and start the company Dopper was initiated by the beach. In October 2009, after watching a documentary about ‘plastic soup’ Merijn Everaarts realized that we are living in a world with a very big challenge to overcome; to search for a solution for plastic waste and a better plastic lifestyle. The realization after watching the documentary was shocking, as was learning how toxic single-use plastic is. Something had to change, not tomorrow, but today. From that moment it began to frustrate Merijn – seeing so many PET bottles and plastic bags around. The volume of PET bottles was the most annoying and he started asking people why they used them. In the beginning he thought it was because they wanted mineral water, but everybody proudly noted that they reusing that bottle daily. It was not about the mineral water, but the bottle, so if people want a bottle, they can get a nice and sustainable one! The concept for the Dopper was founded.
