ENVITEC A.E. undertook as a leading partner of Κ/Ξ - the construction of EMAK. The project is owned by the United Association of Municipalities and Communities of the Prefecture of Attica (ESDKNA) and the location of the factory is in Ano Liossia, adjacent to the Landfill of West Attica, a project that has also carried out ENVITEC SA.

EMAK is part of the general environmental planning of Ε.Σ.Δ.Κ.Ν.Α. and processes about a quarter of the daily waste generated in the Attica Basin.

Short description

EMAK in Ano Liosia, Attica is one of the largest recycling plants for Mechanical - Biological waste treatment in Europe and is developing on a total land area of ​​178,000m², with 14 building units with a total covered area of ​​47,840m².

The factory as a whole was designed by the team of ENVITEC SA. both in the studies required for its licensing and in the final and implementation studies of the entire construction.

The Project was designed with the following data:



Mixed municipal waste

340,000 tpa

Green waste

38,000 tpa

Biological sludge

16,000 tpa

Installed power

11.650 KVA
