Wouter Oltheten

Former intern, now Product Engineer, Water Treatment

“As an intern at Ridder, I was given the opportunity to apply and increase my technological knowledge and skills in a practical setting. My internship at Ridder was very challenging, but the end result was really appreciated. I mostly worked independently, but whenever I had a problem, everyone was willing to help me. My internship assignment really felt like my own project that I was fully responsible for. I am now a Ridder employee and have been allowed to continue the project and further develop my design into a fully-fledged product. A unique opportunity that I am very grateful for.”

Jorge Gonzalez

Former intern, now Technical Consultant

‘’During my time as an intern I worked on the improvement of the Ridder CO2 Optimizer. This is an algorithm that combines both costs and benefits of supplying carbon dioxide to calculate the optimum CO2 concentration that the grower should have in the greenhouse. Doing my internship at Ridder allowed me to experience how science is applied in a commercial product and that was a very fulfilling experience. Now I work as a Technical Consultant and I am enjoying the challenge.’’
