What Biolargo Engineering does

BioLargo Engineering, Science & Technologies (BLEST) is a wholly-owned subsidiary of BioLargo, Inc. (OTCQB:BLGO), founded in October 2017 and headquartered in Oak Ridge, Tennessee with a West Coast office in Westminster, California. The company operates as a full-service environmental engineering consultancy and technology provider, serving industrial manufacturers, municipalities, federal agencies (notably the U.S. Air Force), and healthcare facilities. Its engineering services span environmental audits, regulatory compliance and permitting, hazardous/solid waste treatment, wastewater treatment, water system disinfection (including Legionella control), and odor and VOC control. The firm also manufactures and licenses proprietary treatment technologies—principally the Aqueous Electrostatic Concentrator (AEC) for PFAS removal, the Advanced Oxidation System (AOS) for water disinfection, and the CupriDyne Clean Industrial Odor Eliminator for odor control.

The AEC technology uses electrostatic separation with proprietary membranes to remove more than 99% of PFAS from contaminated water at energy costs reported as low as 30 cents per 1,000 gallons, generating approximately 1/1000 the PFAS-laden waste of carbon filtration. AOS enables simultaneous water disinfection and micropollutant treatment with a lower carbon footprint than alternatives. CupriDyne Clean eliminates (rather than masks) odor-causing compounds and VOCs and is deployed at the four largest waste handling companies in the U.S. The portfolio is supported by 80+ awarded grants, multiple issued patents (including five U.S. and one Chinese patent associated with subsidiary leadership), and an EPA SBIR Phase I grant.

The company monetizes through professional services fees (project-based consulting), government subcontracting (recurring Air Force base work across five bases in New Mexico and Arizona), and product/hardware sales of proprietary treatment systems. Distribution is hybrid: direct enterprise sales for engineering services and a channel partnership with Product Recovery Management (PRM), a UL-certified equipment integrator with a 250,000 sq ft manufacturing facility in Butner, NC, that serves as authorized reseller and contract manufacturer for AEC and AOS systems. Pricing is quote-based and not publicly disclosed. Strategic partnerships include an MoU with Aquatech to pursue global PFAS remediation projects and a co-development arrangement with Garratt-Callahan for a minimal liquid discharge (MLD) wastewater system.
