Our Team

Joost de Kluijver

Founder

Greener Tech can also be appealing and fun. I’m really excited to see how CTL is turning positive impact into commercial and social value. I lead the commercial department for this great industry innovation, which means I connect to B2B tech users and their suppliers. Connect to me for questions on how the tech you use can be more aligned with your values - and why that is a smart thing to do.

Reinhardt Smit

Supply Chain Director

I grew up in South Africa and Ghana and have seen what opportunities the African continent brings. I put this experience to use in ensuring that our supply chain delivers the quality of service we promise our customers. I manage the company operations, including the supply chain. You can reach out to me to explore potential supply chain partnerships.

 

Ana Maria Alvarez

Marketing Director

After 14 years in a corporate environment in various marketing roles, it was time for me to start a new chapter and join CTL as Marketing Director. What I most look forward to is working with our clients, bringing together the waste compensation message in an impactful way. Reach out if you want to know how CTL fits your corporate values, or how we together can tell the story that speaks out to your stakeholders.

 

Ryan Bark

Joining Closing the Loop is really closing the loop for me in bringing together my passion for technology in a commercial environment and making an impact today that makes sense to my children. You can reach out to me with any questions on commercial partnerships and to get started on sustainable IT. 

 

Wiske Hermans

Inside Sales Specialist

I like how CTL found a pragmatic way to create social, environmental and economic impact, as soon as today. By not focussing on the problem, but rather on solutions, and acting on them. I can help both existing and new clients to implement, market and communicate green tech CSR ambitions. Connect to me if you'd like to find out how Closing the Loop's innovations could compliment your companies values.
