Biowalls to Spare the Air
Maria Paz Gutierrez has begun to explore the potential of using lichens rather than plants as living air purifiers, and installing them along interior walls, rather than exterior walls. With support from the Bakar Fellowship Program, Dr. Gutierrez aims to fabricate small-scale “lichen building blocks” and test their capacity to purify indoor air. She describes her unorthodox approach and what drew her to it.
