Here we are 25 years on. Time flies when you’re having fun. Three pioneers started NOTOX and developed it into an international company with over 300 employees. And the end is not yet in sight. So for the entrepreneurs right from the start, it is a treat to walk through the brand-new NOTOX unit in Den Bosch in preparation for the interview that we are holding for a look back over 25 years of NOTOX. It is great to take a look at the current state of the technology and it is a lovely chance to meet a lot of old acquaintances again. And for Wilbert Frieling, the current director of the company, it is a proud tour: things are going well for NOTOX. Read more in The secret of NOTOX.
