Die Semiosphäre von Le Commun

Phytomining research @ Die Semiosphäre von Le Commun, Geneva

In 2015 and 2016 members from Top association were working on Phytomining, a technology that use living plants to clean up soil, air, and water contaminated with metals and chemicals. On the 2nd of March Mindaugas Gapsevicius and Juan Pablo Diaz present at the Die Semiosphäre von Le Commun in Geneva their research.

The project entitled « The Semiosphere of the Commun » emerges from the very space of Le Commun. We learned that in 2006 the Building Services entrusted the engineering-environment-safety company Ecoservices SA to carry out tests for pollutants potentially present at the BAC. In parallel, the STEB (Service de toxicologie de L’environnement bâti du Canton de Genève – the Service of Toxicology Service of the Built Environment, Geneva Canton) measured the quality of air in a number of spaces of the building. The laboratories tested the samples taken from the floors and the false ceilings for presence of heavy metals, PAHs (Polycyclic Aromatic Hydrocarbons) and asbestos, and found an important level of hydrocarbon pollution in all surface samples taken from the wooden and screed floors, dating back and inherited from the industrial period of the building. The PAHs were also present and even released in more or less important quantities depending on temperature variations. Heavy metals were occasionally present in excess. The tests showed presence of asbestos in the glue used to fix the wooden floors on the ground floor as well as in the ceiling panels. The detected asbestos is non-porous and does not present a health hazard as long as it remains untouched. In conclusion, Ecoservices SA considers the site to be contaminated, but without danger for medium term occupants
