Our Team

Joost de Kluijver

Founder

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.

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.

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.

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.
