Technology shown to turn municipal wastewater algae into specialty chemicals for biofuels, bioplastics

Startup receives support from two environmental accelerator programs

A startup is advancing a unique way to transform algae used to purify municipal wastewater into specialty bio-based chemicals such as biofuels or bioplastics that could help reduce the risk of toxic algae blooms that often kill fish and surrounding wildlife.

Algae from wastewater treatment facilities is typically disposed of in a landfill, which can be costly and environmentally challenging.

“There is a better way to repurpose this algae. We use our patented enzyme technology to break open the algae and take out the sugars, fats and proteins, and convert those into specialty chemicals,” said Kelvin Okamoto, founder and chief executive officer of Gen3Bio, a startup commercializing the technology. “It’s a way to keep the carbon cycle going by renewing the use of the algae into useful and safe products.”

After the extraction of nutrients, various specialty chemicals can be made and sold. For example, the proteins and lipids can be dried into products such as agricultural fish food.

With Gen3Bio, a portion of the revenue generated from the specialty chemicals is given back to the facilities.

Gen3Bio has been accepted into two accelerator programs focused on advancing new environmentally friendly technologies – the BREW in Milwaukee and Carbontech Labs in San Francisco.

“It’s a great opportunity for us to get guidance from mentors, network with people in the wastewater treatment industry and ultimately pitch our technology to interested investors and customers,” Okamoto said.

The BREW accelerator, sponsored by The Water Council, focuses on fresh water, wastewater treatment and water treatment technologies. Currently, five companies, including Gen3Bio, are involved in the BREW accelerator. The BREW accelerator offers those selected $50,000 in funds, connections to office and research space, and access to mentors. At the end of the program in June, Gen3bio, along with the other participants, will pitch their technologies to a panel of investors.

Carbontech Labs is sponsored by Carbon 180, which is working toward a carbon-neutral society in hopes of rolling back carbon levels in the atmosphere. Gen3Bio is in the first cohort of this virtual accelerator program.

As part of its participation in the Carbon Tech Labs accelerator, Gen3Bio has been assigned a resident entrepreneur to provide guidance.

Gen3Bio is based in the Purdue Research Park in West Lafayette, Indiana, and has received assistance from the Purdue Foundry, a startup accelerator based in the Burton D. Morgan Center for Entrepreneurship that works with any Indiana-based company. The technology is patented and exclusively licensed from the University of Toledo. Okamoto also works out of the Purdue Railyard Coworking Space located in the Kurz Purdue Technology Center.

The technology also aligns with Purdue’s Giant Leaps celebration of the university’s global advancements made in health, space, artificial intelligence and sustainability as part of Purdue’s 150th anniversary. Those are the four themes of the yearlong celebration’s Ideas Festival, designed to showcase Purdue as an intellectual center solving real-world issues.


About Purdue Research Park

The Purdue Research Park is managed by the Purdue Research Foundation and is the largest university-affiliated business incubation complex in the country. The Purdue Research Park manages the Purdue Technology Centers in five sites across the state of Indiana with locations in West Lafayette, Indianapolis, Merrillville and New Albany. The more than 260 companies located in the park network employ 5,000 people. In 2016, the Association of Public and Land-grant Universities co-named the Purdue Research Park a top recipient for an Innovation and Economic Prosperity Universities Designation for its work in entrepreneurship.
