BioFiltro is an environmental services company based in Davis, California, that treats wastewater using vermifiltration. Its Biodynamic Aerobic (BIDA) system channels wastewater through a layered filter of biomass, earthworms, microbes, and drainage cells, achieving up to 90% contaminant removal in roughly four hours. The process yields soil amendments derived from earthworm castings and associated microorganisms, endowing soils with beneficial properties while creating zero waste at the end of the cycle. The system is designed for accessibility and scalability, capable of being installed to meet an operation’s size and to adapt to seasonal or climate-driven variations in discharge. BioFiltro serves farmers, food processors, municipalities, and other organizations seeking to reduce environmental footprints and derive economic benefits. The company has designed and installed more than 200 wastewater treatment systems in nine countries across four continents. A 2024 collaboration with Tri-Cities Airport demonstrates ongoing adoption of its vermifiltration approach in diverse settings.
