Plastic is the recurring theme in the life of Daniël Poolen (1985). Daniël works at Rabobank as a sustainable researcher in the field of circular economy and energy transition with a special interest in plastics.

In the past, Daniël worked for WWF and NPO, among others. He created and presented various (youth) programmes such as Ik, plastic (Me, plastic), Zapp your Planet and Nederland in 2050 (The Netherlands in 2050). In 2022, he combined all his knowledge on plastic and plastic pollution in the children's book Tot over mijn oren in het plastic (Up to my ears in plastic). For this book, he collaborated with illustrator Merel Corduwener.
