BioFiltro is a Davis, California–based provider of nature-based, low-energy wastewater treatment solutions built around its patented BIDA® vermifiltration system. The system leverages earthworms and microbes to strip up to 98% of contaminants from agricultural, industrial, sanitary, and municipal wastewater while materially lowering energy use, greenhouse-gas emissions, sludge production, and operating costs compared with conventional technologies. The company serves clients across North America, South America, and Europe, and it is rapidly scaling within the U.S. dairy sector. By transforming wastewater into clean water and nutrient-rich soil amendments, BioFiltro helps customers cut costs and meet sustainability targets. The firm recently secured a $35 million strategic investment to fuel expansion, signaling a strengthened balance sheet and capacity for accelerated growth. Management intends to channel the new capital into deeper penetration of the dairy market and broader adoption across food processing and other industrial verticals.
