BioLargo's AEC Removal of Forever Chemicals PFAS is Confirmed 99.995% Effective in Lab Analysis Performed at the University of Tennessee

AEC Features Dramatic Reduction in Carbon Footprint Associated with Disposal

WESTMINSTER, CA / January 26, 2021 / BioLargo, Inc. (OTCQB:BLGO), a developer of sustainable technologies and a full-service environmental engineering company, today announced new testing on its AEC water technology system, which has been proven to remove 99.9% of PFAS (so called "forever chemicals") from water in a single pass. PFAS chemicals are a new focus of the Biden Administration, who's nominee for EPA Administrator, Michael Regan, is being heralded by environmental groups for his work combatting PFAS contamination in North Carolina.

PFAS are a class of man-made chemical contaminants that are bioaccumulative and are associated with a host of serious health problems. Last week the US EPA announced it had issued "final regulatory determinations" to that will officially regulate safe levels of PFAS chemicals in drinking water.

Testing at the University of Tennessee in Knoxville showed that PFAS compounds are attracted and bound to the surface of the AEC's proprietary membranes, which in a single pass collect over 99.995%, such that less than one out of 50,000 PFAS molecules was able to penetrate the membrane.

Randall Moore, President of BioLargo Engineering commented, "This study confirms that the AEC is effective to selectively extract PFAS from water in an extraordinarily cost-effective way. Competing technologies reliant on carbon media create a significant amount of carbon waste that is often incinerated, releasing greenhouse gas emissions. This new study confirms the AEC reduces the waste produced to a fraction of the competition - imagine that to treat the same volume of water, while carbon solutions will create a truckload of spent carbon for disposal, our AEC system will create a waste product the size of a brief case."

Dennis P. Calvert, CEO at BioLargo commented, "With the recent EPA action and Biden Administration's focus on these ‘forever chemicals,' our AEC technology is in a position to become an industry standard. Thankfully, our team recognized the need for efficient removal for PFAS early and has invested the last two years developing the AEC to a now ready for commercialization stage. We are preparing for commercial trials as soon as possible and have a number of municipal water agencies that want to work with us. We expect to share more information about our AEC as it progresses."
