Biolargo (BLGO) water cleaning technology could bring clean water for all

For those that have not seen that PFAS is all over the media:

NBC- Toxic ‘Forever Chemicals‘ Are Found Everywhere. What You Need to Know About PFAS

Keep in mind that as of today we do not know of any more effective and efficient targeted PFAS removal technology than BLGO’s AEC.
And we learned last week in the great Interview with BLGO’s Director of Strategic Marketing and Business Development Tonya Chandler that they will be offering on top of getting the PFAS out of the water to take care of the Contaminated Membranes etc. as well.
So BLGO will offer a “no headache full service PFAS remediation solution” that might become a standard go-to solution In the future.

BioLargo to treat contaminated PFAS water from a major municipality and a federal government agency

BioLargo Aqueous Electrostatic Concentrator (AEC) is designed to provide rapid, effective, and affordable concentration of per- and polyfluoroalkyl substances (PFAS) in water.

It works by separating PFAS compounds in an electrostatic field and forcing them through a proprietary membrane system. The result – the AEC removes >99% PFAS from water in a continuous flow, at energy costs as low as 30 cents per 1,000 gallons.

Advantages over other technologies:

  • More energy-efficient
  • More affordable on per-gallon basis
  • Much less PFAS-laden waste produced
  • Less activated carbon required in PFAS life cycle
  • Higher purity of final water
  • Compact; small footprint
  • Development and commercialization of the AEC is supported in part by a grant provided by the US EPA SBIR.

From The National Law Review – July 30th
“EPA PFAS Release Data Made Public”
“Many companies assume that any regulation under the Safe Drinking Water Act will not impact them, as virtually no industries, aside from water utilities, have any direct impact on drinking water. However, this belief provides a false sense of security that must immediately be dispelled. There are three specific ways that drinking water limits for PFAS will trigger scrutiny on environmental practices of businesses: (1) effluent discharges into water sources; (2) waste sent to landfills that may leach into drinking water sources; and (3) properties abutting or in the vicinity of water sources.”

“Direct industry effluent discharges into water sources (which may not be drinking water sources, but may feed into drinking water sources) will be the low-hanging fruit target for local environmental agencies at the state level. Companies must ensure that they have all permitting in order, and it is advisable that the permitting specifically encompasses PFAS. Failing to do so will cause issues down the line when local environmental regulatory bodies look to determine, even retroactively, who PFAS water polluters are or were, as those agencies seek to hold businesses responsible for the costs associated with cleaning up PFAS in drinking water. “

Our prediction remains that sometime in 2022, PFAS drinking water rules will be finalized at the federal level. This will require states to act, as well (and some states may still enact stronger regulations than the EPA). Both the federal and the state level regulations will impact businesses and industries of many kinds, even if their contribution to drinking water contamination issues may seem on the surface to be de minimus. In states that already have PFAS drinking water standards enacted, businesses and property owners have already seen local environmental agencies scrutinize possible sources of PFAS pollution much more closely than ever before, which has resulted in unexpected costs. Companies absolutely must begin preparing now for regulatory actions that will have significant financial impacts down the road.”

BioLargo begins testing source waters from prospective clients with its PFAS treatment technology

WESTMINSTER, CA / ACCESSWIRE / July 26, 2021 / BioLargo, Inc. (OTCQB:BLGO), a developer of sustainable technologies and full-service environmental engineering company, announced that two potential clients (a major municipality in Southern California and a federal government agency) are sending it PFAS-contaminated water samples to be treated by BioLargo’s AEC water treatment system.

This is the first step of BioLargo’s multi-phased commercial approach:

(1) off-site treatment of client-supplied water,

(2) on-site pilot treatment at client location, and

(3) full-scale operation.

In this first step, BioLargo receives contaminated water from the client, evaluates it for operational optimization, treats the water removing the PFAS chemicals, and then has an independent laboratory analyze the treated water to confirm the PFAS has been removed to client specifications.

In essence, it is a “proof of concept” phase to give the client confidence in moving to the next phase. Assuming a successful first phase, these agencies have asked for proposals for on-site piloting to confirm treatment success at a larger scale at the client location. Once piloting is complete, BioLargo would offer customized commercial-scale systems to each client.

Randall Moore, President of BioLargo Engineering, Science & Technologies said, “By treating client water through our in-house AEC system, we can optimize it for the unique characteristics of the water from each source and confirm for the client that our system removes PFAS to the levels that meet their particular regulatory requirements.”

The AEC (Aqueous Electrostatic Concentrator) is BioLargo’s proprietary water treatment technology specifically designed to remove PFAS (per- and polyfluoroalkyl substances), a group of man-made “forever” chemicals of great emerging regulatory concern (learn more about PFAS on our blog post here:, from water and soil.

On July 21, 2021, the House of Representatives passed the “PFAS Action Act of 2021″. Introduced by a bipartisan coalition in March 2021, the proposed legislation would establish a national drinking water standard for select PFAS chemicals under the Safe Drinking Water Act, designate them as hazardous chemicals (allowing the EPA to clean up contaminated sites and creating stricter rules for handling them under CERCLA), limit industrial discharges under the Clean Water Act, and provide $200 million annually to assist water utilities and treatment facilities to remove PFAS chemicals from their water. The bill would also restrict incineration of PFAS-containing wastes under the Clean Air Act, which could significantly limit the use of the most common treatment strategy: carbon filtration followed by carbon incineration.

BioLargo’s AEC technology has been proven to remove more than 99% of PFAS from contaminated water, and, compared with carbon filtration systems, generates about one-tenth the PFAS-laden waste and costs less to operate. Decreased waste minimizes the environmental and regulatory burdens associated with water treatment.

Tonya Chandler, Director of Strategic Marketing and Business Development at BioLargo, said “With the passing of the PFAS Action Act of 2021 by the House of Representatives, PFAS regulations are just around the corner. BioLargo is in a perfect position to launch its revolutionary PFAS removal system into the market. The AEC produces significantly less waste than traditional systems making it a superior solution in this regulatory environment.”

Great that there is a running AEC system that is treating the water of potential clients. This way we should get more verification data about PFAS removal much faster and BLEST can fine-tune the entire system to then be able to get the best possible AEC’s out to clients. This is a tiny company with top notch science/products/solutions and a world-class engineering Division that “Make Life Better” by working on Clean Air, Clean Water, and a Cleaner Earth.

BTW – now it makes total sense that the engineers opened their California office earlier this year

It is way too early to predict what kind of market share BLGO will be getting. But just any kind of involvement in PFAS remediation (an estimated $1 TRillion Endeavor to clean up) will value this a lot higher than the current $50 Million Market cap. And this is “just” the AEC.

This is a list to summarize all the endeavors that could move the needle for BioLargo:

  1. AEC- as of now Best known targeted PFAS removal technology
  2. Cupridyne Clean Consumer- Media push coming
  3. AOS- best known micro pollutants killer – after years of development finally in commercial trials
  4. Cupridyne Clean – potential wide adoption (ODIN / Cannabusters)
  5. Minerals extraction – in hard negotiations- Being a project manager, small partner, engineer, and building out the pilot facility of a $1 billion+ project sounds pretty lucrative
  6. Successful Clyra Medical Product launch
  7. EPA list N inclusion for Cupridyne/Clyra products
  8. Garratt Callahan partnership- product they bring to market. ($3-4 Million early revenue expected)
  9. Other Blest Projects. (Signed $1.2 Million in contracts within 10 days)

The Bull thesis

Commercialization is in full swing; revenues growing and debt paid off and at least one of those above mentioned endeavors will become a big success. More than one and we will do amazingly well – but it is actually looking good that a lot of not all will become a success = a potential Clean Tech Jackpot.

The Bear thesis

BioLargo has been a company operating for more than a decade and they spent way too long in R&D without being able to significantly monetize their developments. As a “logical” consequence they will never be able to monetize anything and not a single one of the above will succeed.


It is very obvious that some folks got disappointed because they bought in BioLargo very early and missed buying back on the lows or averaging down.

So if you would hear about a company that Besides many other promising endeavors – has solutions for two of the massive global water problems and a Billions of dollars bill just passed that is going to invest into clean water in the USA and the entire company is worth just around $50 Million- what would you think?

Right, It sounds too good to be true.

But folks it is not. We have been following BioLargo closely, and what they set out to do is actually happening (with some delays). There is no debt and progress is happening on all fronts.

It’s unheard of to have a purposeful company with that many promising endeavors at a price like this.

IMHO BioLargo is one of the best investing opportunities out there – the perfect combination – investing in the “clean” future while going for the big bucks.

Do your own DD and invest accordingly.
