BioLargo Provides Progress Report on Major Growth Catalysts

Westminster, CA – February 17, 2022 – BioLargo, Inc. (OTCQB:BLGO), a developer of sustainable cleantech technologies and full-service environmental engineering company, today provided an update on the progress of three important catalysts for commercial growth. 

“These initiatives are still unfolding, and in some cases, such as with PFAS testing on behalf of clients, we have to handle confidential information carefully,” said Dennis P. Calvert, President and CEO of BioLargo. “Still, we believe it’s important for our investors and followers to stay abreast of the progress of these projects that represent the key growth catalysts for our company.”

1) Garratt-Callahan / BioLargo Minimal Liquid Discharge Water Treatment System passes “factory acceptance testing”

A commercial prototype of the new “minimal liquid discharge” water treatment system, invented by North America’s largest privately held water treatment company, Garratt-Callahan, and engineered and built by BioLargo, passed the “factory acceptance” testing this week conducted by both BioLargo and Garratt-Callahan engineers at BioLargo’s Oak Ridge, Tennessee facility. The new water treatment system is designed to reuse and recycle, rather than discharge, treated wastewater, resulting in lower operational costs and less environmental impact for customers.

At this week’s performance testing, the system removed over 98% of the target contaminants from water provided by a Garratt-Callahan client in continuous operation, in line with results achieved by Garratt-Callahan’s original bench-scale and batch processing tests. This factory acceptance testing was a necessary step before commercial trials with Garratt-Callahan customers can begin. The first customer has already been identified, and the first on-site field trial for that customer is currently being planned.

Kelle Zeiher, Technical Project Manager at Garratt-Callahan, commented, “I’m excited about helping our customers move from water discharge to water reuse. This technology represents a dramatic, game-changing shift in how we manage industrial water for a more sustainable future.”

2) PFAS treatment solution 

Commercialization of BioLargo’s revolutionary PFAS removal system, the “Aqueous Electrostatic Concentrator”, or AEC, is progressing. While the company can’t give details on confidential client communications, nor reveal details of new innovations, it has recently completed a series of further studies with a potential client’s water to optimize technical and economic metrics and simulate the real-world conditions of a commercial trial. BioLargo’s engineers are currently preparing a final techno-economic case study report for the client that will be integral for establishing in-field trials at the client’s facilities, as well as at other prospective customers’ sites.

Additionally, BioLargo engineers recently completed in-house testing of the AEC using PFAS-contaminated water provided by BioLargo’s a federal government agency. While internal preliminary testing shows the AEC eliminated PFAS from the water stream, the treated water samples have been submitted to the University of Tennessee for determinative analysis.

On the commercial side, BioLargo is in discussions with both prospective customers and potential channel partners to develop and support sales and distribution of the AEC. 

3) Pet odor control product

As previously disclosed, BioLargo and its strategic partner, Ikigai Marketing Works, LLC, are working together to support Ikigai’s roll-out of a new pet odor control product based on BioLargo's proprietary technology. They have completed test marketing and their product orders from BioLargo thus far have exceeded the company’s expectations. Ikigai is comprised of veteran consumer product executives with experience launching and growing multiple blockbuster consumer products. Both BioLargo and Ikigai are excited about the opportunities ahead for this and potentially other pet-oriented products. 

BioLargo CEO Dennis Calvert commented, “We are making steady progress towards commercialization of our water treatment systems and have the benefit of working with experienced channel partners to get there. We’re also highly encouraged by the performance of the pet odor product being rolled out by partners at Ikigai. To say the team at BioLargo is excited would be an understatement.”
