Transforming Pollution to Power

Wastewater treatment facilities often exceed EPA pollution limits, which can lead to fines or even jail time. Using our proprietary technology, Manta Biofuel's mobile wastewater treatment system quickly and cost-effectively cleans polluted bodies of water. Pollutants, like algae, can ultimately be converted into renewable carbon neutral fuel. We have demonstrated our patented technology in the field, and we are ready to scale.

This Reg CF offering is made available through StartEngine Capital, LLC. This investment is speculative, illiquid, and involves a high degree of risk, including the possible loss of your entire investment.

$542,021.45 Raised


Trusted by Top Investors: We’ve raised over $5.2M in public and private investment. This includes over $3 million from the U.S. Department of Energy and the State of Maryland and $2.2M from private investors like Exelon (a Fortune 100 corporation), professional angel investors, and over 4,000 crowdfunding investors.

Experienced Leadership: Our CEO Chris Lindsay has 30+ years of experience in the biotech industry, having held executive roles at both large multinational and startup companies. Our Founder and CTO Ryan Powell holds a PhD in algal biofuels, is the inventor of our core technology, and has nearly 20 years of experience in science and technology.

Strong Market Traction: In 2022 we launched our water treatment service, realized our first revenue, executed multiple successful field trials around the country with prospective customers and lined up more demonstrations for 2023. Funds are needed to scale our commercial operations and capitalize on this momentum.

the pitch

Our patented technology removes pollutants, like algae blooms and excessive nutrients, from water more sustainably than traditional methods for a fraction of the cost. Combining established water treatment processes with our proprietary magnetic filtration technology allows us to fit the power of a water treatment plant in a highly mobile footprint. This unique mobility opens largely underserved segments of the $300B water treatment market (source). Manta can then leverage its experience in biofuel production to convert collected pollutants like algae into a carbon neutral fuel. By combining our innovative water treatment technology with our experience in biofuels, we will simultaneously address two critical issues facing the world today- water pollution and climate change. 


Transforming Pollution to Power

Manta was founded with the ultimate goal of converting algae into carbon neutral biofuel. In the quest to make this dream a reality, we realized that our cutting-edge magnetic separation technology could also be used to quickly and economically clean polluted water. We discovered a way to address two environmental problems at once: water pollution and carbon emissions.

The problem

Polluted water and climate change are problems that impact everyone

Cleaning water is an >$300B industry and there are large segments of this market that are not being served (source). Since 2018, nearly two-thirds of all wastewater treatment lagoons have at least one pollutant exceeding EPA standards (source), often caused by excessive growth algae. These EPA compliance violations can mean hefty fines or even jail time. 

80% of all wastewater treatment facilities serve small communities and typically use lagoons to clean their water (source). Addressing these EPA violations often requires installation of new equipment, taking years and costing $5 million or more.

Picture of wastewater lagoons

Operators need to solve this problem but it is often not financially feasible for many communities. An operator had this to say: 

“When we have this problem there is no one we can turn to for a solution”.  

-Dave Dollinger, Director of Public Works, Toluca Illinois

And the situation is only growing more challenging. Climate change is making things worse because higher temperatures due to global warming are causing more severe algae blooms (source). Meanwhile, population growth stretches many wastewater treatment facilities to their limits, with 81% operating at near capacity and 15% are already over capacity (source). Operators like Dave are stuck. They want to do the right thing, but don’t have the resources to fix the problem.

Climate change is causing significant damage to society and the environment

Manta was founded to convert algae to renewable fuel to fight climate change. Collecting and converting waste algae is a better way forward to address the need for renewable fuel. The United States alone consumes nearly 20 million barrels of fossil fuel every single day, emitting 300 trillion pounds of CO2 annually (source, source). There are some sectors such as air travel and cargo shipping that will be difficult to move away from liquid fuels.

Our Solution

A cost-effective, mobile water treatment solution for addressing acute water pollution 

Our cutting edge process uses black magnetic sand, called magnetite, and powerful magnets to rapidly remove >90% of contaminants, like algae and phosphorus, from the water. 

Traditional water treatment systems require massive footprints and massive checks, but our proprietary, magnetic separation technology allows us to pack the power of a water treatment plant into a trailerable, cost-effective mobile system. 

Our compact system is very efficient and removes target contaminants to well below EPA limits. Over 90% of problem pollutants , like algae, excess nutrients, and other contaminants are continuously removed from over 75,000 gallons of water daily. 

This mobile approach gives us access to markets that could not be previously addressed, such as rapid treatment of acute water problems nearly anywhere. Our solution can be deployed on an as-needed basis for as little as $10K per month. This allows customers like wastewater operators to quickly and cost-effectively address their problems without spending millions of dollars to upgrade facilities. Manta can then ultimately use the algae removed from these jobs as a feedstock to make biofuel.  

Manta knows how to transform algae to fuel

Manta has years of experience in growing, recovering, and converting algae into biofuel. Typically biofuel companies incur significant costs to grow, harvest, and then convert algae to biofuel. We change this equation by getting paid to remove polluting algae that is growing at a customer’s site, then ultimately transforming this recovered contaminant into biofuel. This new paradigm drives significantly more favorable economics for biofuel production.

The Market

Cleaning water is a >$300B dollar industry

And we believe there are key segments of this market that are not being served. 

Manta’s compact, mobile system can rapidly address a wide variety of acute/transient water pollution issues quickly and cost-effectively. Many markets remain unserved by other companies due to the cost and larger footprint of their systems. 

Converting algae from water pollution into carbon neutral fuel could allow access to the $3.5T fuel market 

Manta ultimately plans to transform the polluting algae from its water treatment activities into carbon neutral biofuel. Our algae-based oil, which doesn’t contribute to climate change, can be used to make renewable gasoline, jet fuel, asphalt, bunker fuel, and heating oil. In many markets, renewable, carbon neutral, crude oil is the only way to fully decarbonize the economy.

Our Traction

Ramping sales and growing customer pipeline in multiple markets

In 2022 we launched our water treatment service and quickly gained strong commercial traction. In Q3 2022, we achieved a major revenue milestone with three paid pond treatment projects for the Columbia Association in Maryland.

The watershed manager at Columbia Association had this to say: 

"You guys need a bigger machine so I can use it to treat my lakes!"

- John McCoy, Columbia Association

We used this success to advance discussions with a leader in the pond/lake management space that is part of a multinational company with $3.7B in revenue. This company has nearly 10,000 ponds/lakes under management in Florida alone. We are also in ongoing discussions with another leading solutions provider in the space on how we could integrate our technology.

We continued this momentum and successfully completed a half dozen field demonstrations with prospective wastewater lagoon customers around the country in 2022, filling the pipeline for revenue in 2023. Feedback from the trials was positive and operators were happy to learn that they finally had an option to fix a persistent problem.

More projects in adjacent markets, like municipal wastewater treatment and industrial ponds, are planned for early 2023. In Q2 2023, we have a pilot trial planned with a large multinational water treatment company ($1.7 B in revenue in 2022). We also have an active project with the Maryland Port Administration, treating water from their dredge spoil containment pond. Field trials are also planned in Q2 2023.

Hello! First of all, I love the concept of your business. As I'm sure you know well, crude oil can be refined to make numerous different petroleum products from gasoline, to kerosene, and butane. Is there a particular fuel you're hoping to replicate? Do you know if you'll produce long or short chain hydrocarbons?

Chris extend your raise again for another month or two. Also a quick update. Fundrise has a lot of companies looking to be added to their Innovation Fund. It’s going to take a while as they do very careful research and evaluations to determine if they should invest in a company. I just sent them another reminder to look out for a company called “Manta Biofuel”. Every month i send them a reminder. They do appreciate the reminders i send them. However it could take a while as it seems like they have a never ending list of private and start up companies applying to be added. I would love to see you guys in the innovation fund. So far i can tell they make really good decisions because the companies they added so far are very promising. I see some early stage companies, mid stage companies and late stage companies. They also opened the innovation fund up so shareholders can add more cash to the fund. So the fund can hold more than $1 Billion in cash to be deployed. As we all know the economy is getting ready to bottom out, when it does they know a lot of businesses will need cash that is why they want us shareholders to add more cash in the fund to deploy into innovative companies. We added a lot of more cash, not only that we told them to use a portion of the cash to deploy into Corporate bonds to also help increase Cash on Hands, Fundrise added millions to Uber and Square corporate bonds, those bonds will give them a 15.5% gross return to increase their cash on hand . Hang tight Chris this is going to take some time. Until then continue to extend your raise on here for another month or two. Stay positive.

Thank you, Chris, for your informative responses to my perhaps wonky questions. I find them interesting and helpful. I understand and support your focus on water remediation. It looks like Manta's way to cash flow and profitability, and is a nicely differentiated capability that is readily at hand. I appreciate your reporting on recent progress at Marlay Taylor and the efforts of you and your team. I wish I could invest more now, and hope to do so in the future. Go Manta! Ray

With Regulation A+, a non-accredited investor can only invest a maximum of 10% of their annual income or 10% of their net worth per year, whichever is greater. There are no restrictions for accredited investors.

With Regulation Crowdfunding, non-accredited investors with an annual income or net worth less than $124,000, are limited to invest a maximum of 5% of the greater of those two amounts. For those with an annual income and net worth greater than $124,000, he/she is limited to investing 10% of the greater of the two amounts.

At the close of an offering, all investors whose funds have “cleared” by this time will be included in the disbursement. At this time, each investor will receive an email from StartEngine with their Countersigned Subscription Agreement, which will serve as their proof of purchase moving forward.

Please keep in mind that a company can conduct a series of “closes” or withdrawals of funds throughout the duration of the campaign. If you are included in that withdrawal period, you will be emailed your countersigned subscription agreement and proof of purchase immediately following that withdrawal.

StartEngine assists companies in raising capital, and once the offering is closed, we are no longer involved with whether the company chooses to list shares on a secondary market, or what occurs thereafter. Therefore, StartEngine has no control or insight into your investment after the close of the live offering. In addition, we are not permitted to provide financial advice. You may want to contact a financial professional to discuss possible investment outcomes.

For Regulation Crowdfunding, investors are able to cancel their investment at any point throughout the campaign up until 48 hours before the closing of the offering. Note: If the company does a rolling close, they will post an update to their current investors, giving them the opportunity to cancel during this timeframe. If you do not cancel within this 5-day timeframe, your funds will be invested in the company, and you will no longer be able to cancel the investment. If your funds show as ‘Invested’ on your account dashboard, your investment can no longer be canceled.

For Regulation A+, StartEngine allows for a four-hour cancelation period. Once the four-hour window has passed, it is up to each company to set their own cancelation policy. You may find the company’s cancelation policy in the company’s offering circular.

Once your investment is canceled, there is a 10-day clearing period (from the date your investment was submitted). After your funds have cleared the bank, you will receive your refund within 10 business days.

Refunds that are made through ACH payments can take up to 10 business days to clear. Unfortunately, we are at the mercy of the bank, but we will do everything we can to get you your refund as soon as possible. However, every investment needs to go through the clearing process in order to get sent back to the account associated with the investment.

Both Title III (Regulation Crowdfunding) and Title IV (Reg A+) help entrepreneurs crowdfund capital investments from unaccredited and accredited investors. The differences between these regulations are related to the investor limitations, the differing amounts of money companies are permitted to raise, and differing disclosure and filing requirements.
