Our Team

Joost de Kluijver


The idea behind Closing the Loop was born during a project I did in Tanzania, 2010. My former company brought mobile phones to Africa for reuse. There I saw that mobile phones lead to huge problems at the end of their lifespan. Closing the Loop is the result of a long-term effort and strong local networks. I am proud of that.

Reinhardt Smit

Project Director Africa

I grew up in South Africa and Ghana. After finishing my IT studies and Hotelschool in The Netherlands, I started my own company to improve communication and workflows of organisations and projects. During my work I came across the world of electronic waste and recycling. At Closing the Loop I focus on strengthening the existing networks and helping the organisation grow through my experience and knowledge from Africa.

Contributing to a more social and sustainable world. That’s my mission. Since long I’ve been a catalyst and project lead of several organisations and businesses and I hope to leverage this experience while working on Closing the Loop. A very challenging and urgent matter. Together, I hope to keep on finding innovative solutions for a circular economy that are profitable for everyone.

For me, Closing the Loop is the answer to limit the harm of scrap mobile phones. We strive for a circular business model that is profitable for everyone and environmentally friendly at the same time. With my experience in communications and network in the world of sustainable electronics I put Closing the Loop on the map.
