Waste. Permits. Standards. Compliance.

The environment is our business. We take on the environmental obligations of companies and public bodies and handle them professionally, ensuring compliance with legislation, regulatory requirements and quality and management standards.

Where we intervene

Our services intervene at different stages of the material cycle. Life Cycle Assessment (LCA), a new service we offer, can cover the entire life cycle, from raw material to recovery.

Projects

What we have
already delivered

Public bodies are named. Private projects stay anonymous — and so will yours.

Loading and spreading dewatered sludge on farmland
Reference project · EYATH · 2014–2019

Agricultural recovery of urban sewage sludge

We secured the fields and the agreements with the farmers, carried out the soil sampling and the soil and sludge analyses, obtained the permit from the Regional Committee, and organised transport and spreading under the terms of those permits. After application, further soil measurements to check for any accumulation.

The same work was carried out on a small scale for the Katerini water utility, 400 tonnes in 2016.

The service, in which we hold a depth of expertise rare in Greece, remains available to public and municipal water and sewerage utilities, and to biogas plants that need to manage the digestate they produce.
