Depending on the material properties required of a product, Vitra chooses different types of plastic for the manufacture of its furniture. This always raises the issue of whether new, more ecological alternatives are available, which has led to the development of recycled plastics such as polypropylene. Vitra utilises high-quality recycled polypropylene based on a mix of materials retrieved from household recycling waste, especially used packaging.
The natural shade of the processed recycling material is dark grey, interspersed with tiny specks of pigment. Due to the randomly variable colour composition of the processed waste material, every batch has its own colour nuance.
