Advanced Circular Manufacturing — the industrial process that receives municipal and industrial materials as manufacturing feedstock and converts them into synthetic graphite, recovered metals, and ultrapure water. Investing early.
Carbotura builds and operates Advanced Circular Manufacturing (ACM) facilities — industrial plants that receive municipal and industrial materials as a manufacturing feedstock and convert them into manufactured goods sold in global markets.
ACM is not incineration. It is not recycling. It is not waste treatment. The process runs in an oxygen-free, sub-atmospheric chamber using microwave catalytic energy. There is no combustion, no flame, and no stack emissions. Materials are not destroyed — they are reformed into products with commercial value.
This classification matters. Carbotura operates under NAICS Sector 31–33 manufacturing codes, not solid waste codes. The facility is a factory. The materials a municipality delivers are manufacturing inputs.
Proprietary sub-atmospheric, microwave catalytic conversion. Materials enter as manufacturing feedstock. Products exit as synthetic graphite, recovered metals, and ultrapure water.

The pipeline begins here — not ends here. The York County Circular Offtake Agreement is the anchor asset securing the CLN's revenue case. Executed. Not in negotiation.
The COA governs the 30-year Beneficiation Fee and Circular Royalty™ revenue stream from the York County deployment. This is not a letter of intent. It is a signed agreement.
Phase Initial processes 400 tonnes per day of manufacturing feedstock. The York County site is designed to scale in 100 TPD increments. This is the entry point, not the ceiling.
The York County deployment is held by Carbotura York, LLC — a Delaware-registered SPV purpose-built for this COA. Clean capital structure.
URVS (Urban Reserve Valuation Standard) validation is in process for the York County asset. Successful validation certifies the facility as a bankable institutional asset.
Every Circular Offtake Agreement contains two instruments. The Beneficiation Fee provides immediate, contracted cashflow. The Circular Royalty™ compounds over the life of the agreement.
This deck reflects the York County, PA deployment — Option A at $75/ton Beneficiation Fee (TMC Fee). The Carbotura platform also supports Option B (TMC Fee waived; Asset Swap; Sovereign Resource Royalty) and Exogenesis™ Royalty structures across deployments. See the Series A deck for full platform economics.
The financial model runs on the RC3 (Revenue Conservative Case 3) baseline — a deliberately conservative blended output value that does not model upside from synthetic graphite price appreciation or premium contract terms.
The CLN is the entry instrument for Carbotura's pre-Series A round. Note holders convert into Series A Preferred equity at a discount to the Series A price at the Series A closing.
| Instrument | Convertible Loan Note (Senior Unsecured) |
| Conversion target | Series A Preferred Stock |

| Issuer | Carbotura Inc. (Delaware C-Corp) |
| Use of proceeds | COA execution, facility pre-development, pipeline development |

Five converging conditions make this the right entry point. None of them were true 18 months ago. The CLN window closes at the Series A opening.
The 30-year Circular Offtake Agreement with York County, Pennsylvania is signed. The financial model runs from a contracted revenue floor, not a sales pipeline projection.
Multiple Circular Offtake Agreement conversations are active with other municipalities. The York County execution is creating the proof-of-deployment signal that accelerates subsequent signings.
URVS validation certifies the York County facility as a bankable institutional asset. Successful completion unlocks the path to Circular Bond financing and the institutional capital markets.
CLN investors convert at a discount to Series A price. Once the Series A opens, the CLN closes. Entry after that point is at market rate with no conversion premium.
ACM under NAICS 31–33 is manufacturing — not solid waste. The regulatory pathway for new deployments does not carry the permit burden of WTE or incineration. Municipal partners are recognising the distinction.
