The people behind RITTEC Umwelttechnik:
Every day, we commit ourselves and stand up for the vision of a circular economy.
Our team is a diverse group of experts: interdisciplinary, highly qualified and with a fresh perspective and plenty of experience. We not only have a good eye for technical development tasks, we are also keen to work together with industry partners and customers. With all this in mind, we are dedicated to a successful launch of the RITTEC technologies – for the benefit of our customers and for the good of the environment.
Since our foundation, the number of our employees has grown steadily. Shaping the circular economy is a very dynamic field, which we continuously want to develop gradually. Close cooperation with academic institutions provides us with the opportunity to identify experts for our team at an early stage. Of course, our doors are open to anyone who is interested to join us to promote the circular economy.
