During his career, he made significant improvements to young plant production methods, helping create many important innovations that shaped the company's success in young plants.

During his time at Syngenta Flowers, Piet worked on many important research projects. He evaluated new plant genetics, solved production problems, and testing new product forms. Some of his key achievements include launching the Xtray and Xcarrier systems, helping the company switch to LED lighting, and finding ways to use fewer chemicals in plant production.
