Plastic Planet is an sculptural project by Ralf Schmerberg, the project has been growing into several pieces since the opening of MaHalla 6 years ago. He uses recycled cable residues collected mostly from the KWB company located next to MaHalla. Plastic Planet includes a variety of pieces using different techniques that give birth to the shapes, colours and diverse textures that can be found in a permanent exhibition at the Underworld of MaHalla. There are selected pieces exhibited in different rooms and Halls inside of the building.
