$BLGO BioLargo's PFAS Solution Provides Dramatic Long-Term Cost Savings Compared with Incumbent Technologies

Case studies show the company's innovative capture + destruction two-step approach can offer a scalable, economically feasible solution for PFAS elimination from drinking water, wastewater, and landfill leachate, capable of reducing lifecycle costs by over 80%
WESTMINSTER, CALIFORNIA / ACCESS Newswire / May 5, 2025 / BioLargo, Inc. (OTCQX:BLGO), a company that creates and commercializes sustainable technologies to solve tough environmental and cleantech challenges, announced case study data establishing over 80% long-term lifecycle cost savings of its AEC (Aqueous Electrostatic Concentrator) PFAS solution that can capture and destroy PFAS contamination down to non-detect levels in drinking water, wastewater, and landfill leachate.
The over 80% reduction in lifecycle costs (i.e. costs from replacing filtration media or substrate over time, and disposing of waste) comes from a steep reduction of PFAS-laden waste generated by BioLargo's AEC compared to carbon-based treatment systems, as well as lower replacement costs of BioLargo's treatment materials.
Since the inception of federal and state regulations limiting PFAS levels in drinking water (see https://www.epa.gov/sdwa/and-polyfluoroalkyl-...nces-pfas), incumbent technologies like granular activated carbon (GAC) and ion exchange resins have been found to carry substantial lifecycle costs driven by the ongoing requirement to replace media and the transportation and disposal of wastes resulting their use into landfills or incinerators. Pending regulations from the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) would increase transportation costs for PFAS-laden waste even further.
BioLargo's AEC turns this paradigm on its head, with less ongoing media replacement, less waste, and ultimately total mineralization of that PFAS-laden waste using a separate electrochemical oxidation process. Learn more about the technology at https://www.biolargoequipment.com/pfas-solutions.
The enclosed figure based on the new case study data compares the lifecycle costs of BioLargo's AEC (in green) and a typical GAC-based system (blue) over a 10-year period. The AEC data were collected from trials with client-provided water and include ongoing costs for replacement membranes and costs to destroy the PFAS-laden waste via electro-oxidation. The GAC costs including ongoing costs for replacement carbon filters based on current pricing but do not include costs associated with transporting or disposing of PFAS-laden waste, or other costs like taxes, fees, and capital costs.
Furthermore, unlike GAC and ion exchange, BioLargo's AEC does not suffer from breakthrough or channeling phenomena that can occur with filtration media based PFAS capture technologies especially with short chain PFAS. In addition to better capturing PFAS chemicals, BioLargo engineers expect this will further reduce maintenance costs due to reduced frequency of media change-outs.
"Waste equals cost," said Tonya Chandler, President of BioLargo Equipment Solutions & Technologies. "We built the AEC specifically to capture PFAS efficiently onto small volumes of substrate. That means lower disposal costs, more affordable and less frequent maintenance, lower regulatory liability, and better, budget-friendly economics for utilities and municipalities trying to protect public health."
In an era when the public is demanding safe drinking water and the federal government is stepping up enforcement on PFAS under CERCLA, BioLargo's American-made technology offers a realistic path to addressing tough PFAS drinking water standards with less capital and operational costs than GAC and ion exchange technologies.
