Our Team

Joost de Kluijver


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

Reinhardt Smit

Supply Chain Director

I grew up in South Africa and Ghana. I studied IT and Hospitality in the Netherlands, then got interested in communication and workflows of organizations and projects. Started my own company. In the course of my professional activities, I came across the world of electronic waste and recycling. At Closing the Loop I focus on strengthening the existing networks.

Ryan Bark

Sales Director

Working in Telecoms and the IT sector gave me access to the latest technology without realizing how many resources were needed and what would happen to this technology once it becomes obsolete. Joining Closing the Loop is really closing the loop for me in bringing together my passion for technology in a commercial environment and having impact now in a tangible way that makes sense to my children.

Marc Staalman

Business Developer

IT is creating a positive contribution for our welfare for many years. The only challenge though is that it is lagging behind in our effort to make this world more sustainable and circular. As being active within IT for more than 15 years I'm now glad to contribute to a circular business model which results in sustainability for IT.


Anne Lameijer

Senior Business Developer

As a business developer I am experienced in expanding, developing and overall commercial growth. Over the last 8 years I have been active in hospitality and e-commerce, and ever since I got my first it hardware my personal interest for circularity, sustainability and e-waste has been evolving. Closing the Loop is an ambitious, innovative and creative company that represents an eagerness to make a difference in a rapidly changing climate.

The future includes me, and I am committed to working to accelerate circular and innovative solutions. I joined Closing the Loop because it puts me in the front lines along with companies working to enhance a circular economy, not just talk about it. I am applying my international experience in public and private sectors in Russia and the US building partnerships.


Hannah Jung

Closing the Loop has an innovative and effective business model for circularity and the reduction of e-waste that combines social, environmental, and economic value. I am applying what I know about business and environmental science & policy to support the development of solid operations and procedures for use in Europe & Africa at CTL. I am the person on the team to make the supply chain fully responsible and compliant.
