As part of the PlasticTwist European Union’s Horizon 2020 Research and Innovation Project, GaudiLabs invited HUMUS sapiens for an open research session on micro-plastics in the soil. With Julian Chollet and Josephine Blersch from the mikroBIOMIK society we turned the FabLab Luzern into a DIY research lab and analyzed soil sample with self made centrifuges, filters and fluorescent microscopes. A walk in the newly reconditioned recreational area on the Lucerne Allmende made us realize the extend of the problem. Finally, collected samples were scanned using a hacked HiSeq Sequencing machine.
