3D slag concrete manufacturing solutions for marine biotopes

SLAGREEF is Creative Innovative Ecological


Climate change is dramatically affecting coastal areas. Storms affect beaches and urban facilities placed in coastal lines and produce serious damages to marine ecosystems.

Placement of artificial reefs has proved to be an effective technology to protect the coastal line and to restore the damaged ecosystems.

The main goal of the project will be the manufacturing of artificial reefs for marine biotopes using a large scale 3D printer. The printed material will be concrete with slag aggregates from waste residues of the steel industry, together with calcareous quarry waste.

What are Artificial reefs?


Puzzle Design

  • Circular reef
  • Hollow inside for nutrients flow
  • Modular design in wich various components can be left out to create holes
