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.

Karin Groot

Marketing Manager

For me, working in this social enterprise is a perfect match. Working for Closing the Loop I can use my years of experience in the commercial sector and combine this with my passion for making the world a bit more social and sustainable. Showing organisations how they can already start today to have a practical impact on (e-)waste reduction is my goal.

Pollution is causing a serious threat to life on planet earth so our circularity is key to reduce this problem. Electronic waste is a fast growing part of this pollution issue and needs to be taken care of. Having worked for more than 15 years in the ICT business it is now time to share my knowledge and skills to contribute on reducing electronic waste.

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.

Circular and innovative solutions will be viable for a sustainable future. That's why I joined Closing the Loop. My international experience in the public and private sectors made me realise that companies that operate sustainably could really make a difference in the world. At CTL, I use my experience to create and maintain partnerships on all levels.

Hannah Jung

I joined Closing the Loop because I truly believe in the business model around circularity and the reduction of e-waste, combining social, environmental and economical value. With my background in business and environmental science & policy I use my knowledge to support the development of structured and standardised procedures at Closing the Loop.
