Design and Fabrication Lead
The City of San Francisco, one of the most expensive cities in the world, is facing a public health crisis. Thousands of people of experiencing homelessness lack access to restrooms and have no other option, but to use the streets as a bathroom. This situation is demoralizing for the community and impinges on the city budget with exorbitant cleaning expenses and repair costs for corroded infrastructure. Designed as a human waste solution, the PPlanter is public urinal and sink that uses modular biofilters (microorganisms and plants) to treat urine and wastewater. A rapidly deployable, light infrastructure model, it requires no utility connections and can be easily relocated to meet the City’s changing needs.
The PPlanter is an ongoing research and prototyping project. PPlanter is a project of Urban Biofilter and was originally launched by the Hyphae Design Lab in 2012.
