Principles & Values
Innovation
We continuously evolve, following a path that we were the first to pave — a path that leads in only one direction: forward.
Reliability
For over 20 years, it has been our greatest responsibility.
Because for us, creating circular economy solutions is not just our job — it is the foundation upon which the future is built.
Sustainability
Growth only matters when it endures. When it’s sustainable. That is the purpose guiding our every move. We create conditions for development that add value to society and to the future of Greece.
Transparency
Transparency lies at the heart of all our activities. It is the constant in a continuously evolving course. It defines how we operate and how we perceive our role.
Effectiveness

We keep raising the bar. That’s the only way to grow, to improve, and to fulfill our mission.
