• About us

What drives us

The global economic system consumes vast amounts of resources. This demand cannot be covered by natural, particularly fossil sources for much longer. New solutions appear to develop so-called secondary raw material sources. They recover resources already in use. These technologies are very widely available for metals and water. However, there is a fundamental need for plastics, construction materials and textiles to catch up.

Focussing on the circular economy: We see waste as the raw materials of tomorrow.

Changing material flows into cycles

RITTEC develops technology concepts that close the gaps in material cycles and thus secure available resources for the future.

Key factors

  • Economic and environmental efficiency
  • Positive social impact
  • Quality of secondary raw materials

In the development of our technologies and processes, the focus is on environmental and economic efficiency, as well as the quality of the products and secondary raw materials obtained. Social structures need to be strengthened, especially in developing societies. RITTEC supplies its solutions globally. We provide brand owners, recycling companies and PET manufacturers with the solution for their high quality PET packaging.

Our team

The people behind RITTEC 8.0 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.
