Partnership Mounts a More Sustainable Attack on Algae

Solana Beach-based materials development company BLOOM Holdings LLC has partnered with AECOM, one of the world’s largest engineering firms, on a new way of managing harmful algae blooms in lakes, reservoirs and river systems.

BLOOM’s primary business is using algae harvested and dried by its Mississippi-based parent company, Algix Inc., as a component in the making of more-sustainable flexible foams for use in everyday products, from sporting goods to shoes.

With AECOM’s backing, BLOOM Managing Director Rob Falken aims to scale up the deployment of the harvesting technology, and the subsequent manufacturing of goods, in a big way.

AECOM, which reported more than $17 billion in revenue in the past fiscal year, began talks with BLOOM about a year ago.

Together, they recently landed their first customer, a “private client” in Florida.

Alternative to Chemical

It was an algae bloom that slimed 33 square miles of South Florida’s Lake Okeechobee in the summer of 2016 — growth so intense it became visible from outer space — that proved the impetus for the companies’ strategic partnership.

AECOM, a Fortune 500 company, was researching better ways to manage algae for clients such as municipalities, local governments and state agencies. Bill Colona, a senior project geologist who has been with the firm for 26 years, wanted to identify a more sustainable solution to the issue.

Algae, when it grows wildly, can cause harmful blooms that can reduce water flows, clog filters, make drinking water taste and smell bad and produce toxins. The primary method used to control algae at the moment is by adding copper sulfate to bodies of water in which algae is living. That doesn’t, however, kill the nutrients on which algae feeds, leaving it behind for other algae to consume. At high concentrations, copper sulfate can be toxic to fish and other organisms.

Colona came across BLOOM, which had recently begun producing materials incorporating algae sucked out of China’s Lake Tai, also known as Taihu, a freshwater lake that has been severely affected by algae blooms in recent years, and some smaller locations in the U.S.

Harvesting algae using Algix harvesters removes the nutrients on which algae feeds from the water, reducing the likelihood of future algae growth.

A Global Market

Dan Levy

According to the U.S. Environmental Protection Agency, harmful algal blooms are becoming increasingly common in inland freshwater ecosystems, and have been recorded in all 50 states. It’s happening internationally, too, as temperatures rise, providing an even more comfortable environment for algae to thrive.

And while it was a crisis in the U.S. that brought the companies together, the market appears to be a global one.

“We see this as a world crisis,” said Dan Levy, a vice president with AECOM who heads its environmental business in Florida.

AECOM, as it happens, has the wherewithal to handle issues on a global level: The company designs, builds, finances and operates infrastructure for governments, businesses and organizations in more than 150 countries.

Its role in its partnership with BLOOM is designing and building the infrastructure needed to deploy BLOOM’s trailer-mounted algae harvesting units, which were developed by Algix.

As businesses and governments become more aware of how human activities are negatively impacting natural ecosystems, the companies believe their pitch could get them out in front when it comes to spending on mitigation efforts.

“The true beauty (of BLOOM’s technology) is the ability to take this waste product and turn it into a valuable end product offsetting petroleum usage,” Colona said.

He said the company’s technology looked efficient — and scalable, a necessity for the scope of the work AECOM perceives as possible.

California a Key Market

BLOOM and AECOM are in talks with agencies in Southern California, for which they plan to conduct a demonstration sometime this fall showcasing the harvesting process, about the alternative, chemical-free management method.

Falken said California, with its history of progressive environmental policies, will likely be on the forefront of any move to stop the use of chemicals for algae management.

The challenge is convincing water management agencies, which are tasked with using taxpayer money in a responsible way, to adopt a new way.

“We’re looking at changing the culture of how municipalities deal with algae blooms,” Levy said. “What we’re trying to do is solve the problem and restore the water to its natural state.”
