Material Taxonomy focuses on establishing a clear understanding of the driving material – microplastics – seen through various lenses: origins, chemical compounds, scientific research on atmospheric dispersal. The laboratory is a tight collaboration between the geologist, biologist, ecologist, and gardener, as they begin to understand the ground conditions created by the saturation with microplastics. In addition, a taxonomy of Allium species is deployed, categorizing them based on their root system and above-ground conditions.
