Company Overview

BioLargo, Inc. (NASDAQ: BLGO) is a technology-driven environmental solutions company focused on developing and commercializing proprietary platforms for water treatment, odor control and air purification. The company’s core technology, the Advanced Oxidation System (AOS), uses electrochemical processes to remove contaminants from industrial and municipal wastewater with reduced chemical usage and lower energy requirements compared to conventional treatment methods.

In addition to its AOS platform, BioLargo offers CupriDyne® Clean, a patented iodine-based solution designed for odor neutralization and surface disinfection in commercial, industrial and agricultural settings. This product appeals to customers in food processing, animal husbandry, waste management and hospitality, where effective odor control and antimicrobial activity are critical for regulatory compliance and operational efficiency.

BioLargo operates through specialized subsidiaries, including BioLargo Water and Odor-No-More, to tailor its technologies and services across North America and selected international markets. The company collaborates with engineering firms, technology partners and government agencies to conduct pilot projects and scale its solutions for applications such as refinery wastewater polishing, landfill odor abatement and municipal water reuse initiatives.

Headquartered in Irvine, California, BioLargo is led by President and Chief Executive Officer Dennis P. Calvert, who has overseen its transition from a research-focused organization to a commercial-stage enterprise. The company’s management team brings expertise in engineering, regulatory affairs and business development, positioning BioLargo to advance its product pipeline and expand its presence in the growing environmental technology sector.
