Everything you need to know about our technology, CO₂ supply, and partnership opportunities.
Cryogenic CO₂ purification uses low temperatures to separate CO₂ from contaminants in industrial emissions. CleanCycleCarbon's patent-pending process purifies raw CO₂ to FDA-registered, beverage-grade quality without chemical reagents.
Read more: Cryogenic purification to beverage grade →CleanCycleCarbon produces CO₂ that meets FDA food-grade registration, beverage-grade purity standards suitable for carbonation, and industrial-grade specifications.
Yes. CleanCycleCarbon's technology is feedstock agnostic and captures CO₂ from multiple types of industrial emissions including fermentation, combustion, and biological processes.
Chemical absorption processes require significant reagent consumption, waste disposal, and ongoing operating costs. CleanCycleCarbon's cryogenic approach eliminates those dependencies and produces a cleaner product with a simpler operational footprint.
Liquid CO₂ is held near zero degrees Fahrenheit at a little under 300 psi, and it moves in bulk liquid trailers that carry about 20 tons each. That trailer is the unit of the whole business: production, storage sizing, and delivery economics all divide by it. Storage is not free either, since refrigeration runs against ambient heat for every hour the product sits in the vessel.
Distributed capture means building many smaller purification facilities at emission sources close to demand, rather than a few giant plants in two or three regions. It is the structural answer to the concentration problem behind recent CO₂ shortages: when supply comes from many geographically spread sources, no single well contamination or plant turnaround can cascade into a national shortage.
CleanCycleCarbon works with established distribution partners to deliver CO₂ to commercial end users. Contact us to discuss volume, specifications, and supply availability.
Yes. All CO₂ is captured and purified at facilities within the United States. CleanCycleCarbon is building domestic CO₂ supply capacity to reduce reliance on concentrated, geographically distant sources.
CleanCycleCarbon supplies CO₂ to beverage manufacturers, food processors, agricultural operations, industrial manufacturers, water treatment facilities, and research laboratories.
Because CO₂ is expensive to move and the existing supply base is concentrated in a handful of source types and regions. When a distant source has an outage, the cost and delay of covering from even further away lands on the buyer. Capture facilities built near demand shorten the supply chain, cut transportation cost, and insulate regional customers from disruptions elsewhere in the network.
CO₂ transportation adds roughly $0.10 per ton per mile, so delivered cost climbs quickly with distance. That is why the merchant market is fundamentally regional and why proximity between the production source and the customer is one of the strongest economic levers in CO₂ supply. It is also the core argument for capturing CO₂ close to where it is consumed.
Yes. Ethanol fermentation produces a highly concentrated CO₂ stream, which is why fermentation is already one of the largest sources of merchant CO₂ in the United States. Most ethanol plants still vent that stream. Capturing and purifying it to beverage grade turns a waste product into revenue, though ethanol supply is seasonal, with plant shutdowns that ripple through regional CO₂ markets.
Read more: CO₂ from ethanol plants →Yes. Renewable natural gas upgraders separate CO₂ from methane as a core part of making pipeline-quality gas; raw biogas runs 35 to 45 percent CO₂ by volume, and that separated stream is typically vented. An RNG plant putting 1,000 MMBtu a day into the pipeline vents roughly 38 tons of CO₂ doing it. Capturing that stream and purifying it to beverage grade is exactly what CleanCycleCarbon's process was built for.
Read more: CO₂ from landfill gas →Most CO₂ used in soda and carbonated beverages comes from industrial sources: ethanol fermentation plants, ammonia production facilities, and natural CO₂ wells. The CO₂ must be purified to beverage grade (99.9% purity or higher) before it can be used in drinks. CleanCycleCarbon produces beverage grade CO₂ by capturing it from renewable natural gas upgraders.
The US merchant CO₂ market is led by the industrial gas majors: Linde, Air Products, Airgas (part of Air Liquide), Messer, and Matheson. They source most of their CO₂ as byproduct from ammonia plants, ethanol fermentation, and natural wells, and move it through regional bulk distribution networks. Independent producers, including biogenic capture companies like CleanCycleCarbon, are a small but growing share of the market.
Beverage grade CO₂ meets the International Society of Beverage Technologists (ISBT) specification: 99.9% purity minimum with strict limits on moisture (under 20 ppm), total sulfur (under 0.1 ppm), benzene (non-detect), and dozens of other contaminants. It is the highest purity grade of commercial CO₂ and is required for any CO₂ that directly contacts food or beverages.
Read more: Understanding beverage grade CO₂ →The 2022 CO₂ shortage was caused by multiple supply disruptions hitting simultaneously: contamination at the Jackson Dome natural CO₂ well in Mississippi, planned maintenance at ammonia plants along the Gulf Coast, and seasonal shutdowns at corn ethanol facilities. Because 85% of U.S. merchant CO₂ comes from just three source types in two regions, these disruptions cascaded nationally.
Read more: How the 2022 shortage unfolded →The structural conditions have not changed: most U.S. merchant CO₂ still comes from a small number of source types concentrated in a few regions, and it still moves by truck through regional networks. Any repeat of simultaneous outages, well contamination, ammonia plant turnarounds, ethanol shutdowns, can tighten supply the same way 2022 did. Diversifying the source base is the durable fix, and it is the market gap CleanCycleCarbon is building into.
Read more: Why domestic CO₂ supply matters →Beverage grade CO₂ typically ranges from $150 to $300 per ton depending on market conditions, volume, and contract terms. Prices spiked significantly during the 2022 shortage. Delivered cost also depends on distance from the production source, as CO₂ transportation adds roughly $0.10 per ton per mile.
Food grade CO₂ meets FDA requirements at 99.5% purity for applications where CO₂ does not directly enter the final product. Beverage grade meets the stricter ISBT specification at 99.9% purity with limits on over 20 individual trace contaminants. Beverage grade is required for carbonation in drinks.
Renewable natural gas (RNG) is methane produced from organic waste sources like dairy manure, food waste, and landfill decomposition through anaerobic digestion. The raw biogas is upgraded to pipeline quality by removing CO₂ and contaminants. That removed CO₂ is typically vented but can be captured and purified to beverage grade.
Section 45Q of the Internal Revenue Code provides a per-ton federal tax credit for CO₂ captured from an industrial source and either permanently stored underground or utilized in a qualified application. Following the Inflation Reduction Act of 2022, the base values are $60 per metric ton for utilization, which includes selling CO₂ as a commercial product, and $85 per ton for geologic storage. Industrial facilities must capture at least 12,500 metric tons per year to qualify, and projects must begin construction before January 1, 2033 under current credit values.
They solve different problems. Geologic storage permanently removes CO₂ from the atmosphere and earns the higher 45Q credit, but produces nothing. Utilization puts captured CO₂ to work displacing CO₂ that would otherwise be extracted or produced elsewhere, and builds the supply chains and capture capacity the market runs on. For concentrated biogenic sources near demand, capture for use is often the economically self-sustaining path, no permanent subsidy required.
The chain runs: capture at a concentrated source, purification to the ISBT beverage specification, liquefaction, bulk storage, trailer transport to a distributor or bottler, and quality verification by certificate of analysis at each transfer. Every step is a purity checkpoint, because the CO₂ that carbonates a drink is a food ingredient and is treated like one from the moment it is captured.
Biogenic CO₂ comes from recently living organic material, such as fermentation or biogas from manure and food waste. Captured CO₂ describes how it was obtained, not where it came from: recovered at a source rather than extracted from an underground well. CO₂ can be both, and biogenic captured CO₂ carries the lowest carbon-accounting burden for buyers.
No. Direct air capture pulls CO₂ from ambient air at roughly 420 parts per million, which takes far more energy per ton. Point-source capture recovers CO₂ from a concentrated industrial stream before it reaches the atmosphere. Most commercially available captured CO₂ today, including CleanCycleCarbon's process, is point-source.
Once purified to the ISBT specification, the molecule is identical: 99.9% CO₂ regardless of source. The differences are upstream. Ethanol fermentation CO₂ starts relatively pure but is seasonal, with plant shutdowns that ripple through supply. Biogas-derived CO₂ brings more contaminants like hydrogen sulfide into purification, but it comes from year-round waste streams and qualifies as biogenic.
It means the plant is registered with the FDA as a food facility, follows current good manufacturing practices, and is subject to FDA inspection. Registration applies to the facility, not the gas itself. A supplier claiming food or beverage grade CO₂ should be able to show the registration and a certificate of analysis for each lot.
The International Society of Beverage Technologists publishes the quality guideline for beverage grade CO₂: 99.9% minimum purity with limits on more than 20 trace contaminants. It is a voluntary industry standard, not a regulation. Enforcement happens through the supply chain: bottlers and distributors require a certificate of analysis against the ISBT specification before accepting product.
A certificate of analysis (COA) is the lab-verified record showing what a specific lot of CO₂ actually contains, measured against the specification it claims to meet: purity, moisture, total sulfur, benzene, and the other listed trace contaminants. Bottlers and food processors require one before accepting product. A supplier who cannot produce a current COA is asking you to take purity on faith, which the beverage industry does not do.
It depends on the source. Biogas-derived streams carry hydrogen sulfide and other sulfur compounds, moisture, oxygen, nitrogen, and trace organics; combustion streams add their own profile. The beverage specification limits each of these individually, moisture under 20 ppm and total sulfur under 0.1 ppm among them, so purification has to address every contaminant class, not just bulk purity. That is the engineering problem cryogenic purification solves.
It can help the accounting honestly, but the claim has to be made carefully. Biogenic CO₂ originates from recently living material rather than fossil sources, so it carries the lowest carbon-accounting burden of the available supply options, and buying captured CO₂ supports capture capacity that would not otherwise exist. What it is not is an offset; the honest framing is choosing the lowest-burden source for CO₂ you were going to buy anyway.
CleanCycleCarbon's first commercial facility operates at the Perdue Farms campus in Lewiston, North Carolina. Additional projects are in active development across multiple geographies and feedstock types.
No. CleanCycleCarbon develops, builds, and operates the capture facility on-site. The host facility provides access to the emissions source. No capital outlay is required from the host.
Timeline depends on the specific emissions source and site conditions. CleanCycleCarbon handles the full process: site evaluation, engineering, permitting, construction, commissioning, and ongoing operations.
CleanCycleCarbon is actively expanding and building relationships with capital partners. Contact us to discuss investment opportunities in CO₂ capture project development.
The screening number is tons per day of recoverable CO₂, and the economics are unforgiving below roughly 30 tons per day. A bulk trailer carries about 20 tons, so a source in that range loads out daily or better, keeping liquid moving instead of sitting in refrigerated storage. An RNG plant delivering 1,000 MMBtu a day vents roughly 38 tons of CO₂ and can anchor a project; a single small digester venting a few tons a day cannot, no matter how clean the stream.
Three things dominate the screen: a concentrated CO₂ stream of sufficient volume, year-round operation rather than seasonal, and reasonable proximity to CO₂ demand. Stream concentration sets purification cost, volume sets whether trailer logistics work, and location sets delivered economics. A site that clears all three turns a vented waste stream into a long-term asset without putting capital in.
A vented emission stream becomes productive infrastructure on their site at no capital cost, with CleanCycleCarbon carrying development, construction, and operations. Depending on the project structure, hosts benefit through commercial terms agreed for the site along with the sustainability story of their waste CO₂ entering the domestic supply chain instead of the atmosphere. Specifics are project-by-project conversations.
CleanCycleCarbon does. The develop-build-operate model means the host is not taking on a process plant, hiring operators, or managing product quality and logistics. The capture facility takes the emission stream the host was already venting and everything downstream of that point, purification, liquefaction, storage, loadout, and quality documentation, is CleanCycleCarbon's operation.
Because your upgrader already did the hard separation work, and the CO₂ it strips out is being vented at pipeline-project scale. Raw biogas is 35 to 45 percent CO₂; a plant putting 1,000 MMBtu a day into the pipeline vents roughly 38 tons of CO₂ daily, which is above the threshold where a capture project becomes economic. That stream can become beverage grade product, at no capital cost to you, from equipment and operations CleanCycleCarbon brings to the site.
