Biowall - a vertical wall of living plants. Five-Story Biowall of Plants Serves as a Living Laboratory for Air Quality Research at Drexel
Drexel's new Papadakis Integrated Sciences Building features a five-story vertical wall of living plants – the largest such wall in North America and the only one at a U.S. university. Scientists and students at Drexel are studying the biowall, an active living filter that removes volatile organic compounds from the air, to get a better understanding of how it works.
