Toxic & Persistent Contaminants — Fate Matrix
Every atom entering the ACM must exit through one of four routes: (A) destroyed at CRSRU plasma with atoms redistributed into product streams; (B) volatilized into vapor phase, then captured on activated-carbon guard beds or in the condensate; (C) retained in the OmniCrude™ solid phase and routed through Solids Separation to a MAX Processing Train as product; (D) excluded from the accepted feedstock envelope by contract. Nothing routes to combustion; nothing routes to landfill in routine operation.
Values below are destruction-threshold references from published thermolysis data and design-basis routing rules. Per-site verification is by third-party accredited analytical + post-COD CEMS + classification of any residue stream under the national waste-management regulation.

Architectural framings
- Oxygen-starved regime suppresses de novo dioxin/furan formation. Dioxin formation requires the co-existence of O2, chlorine, and 300–500 °C combustion temperature. None of these conditions co-exist in ACM: primary conversion is sub-atmospheric (~0.5 atm) with no combustion; CRSRU is plasma reforming above 1,300 °C; there is no post-combustion boiler zone. This is a categorical difference from incineration, where dioxins/furans are the primary regulated concern. De novo reformation during gas cooling (chlorine + catalytic metals + carbonaceous matter + trace O2) is a recognized mechanism and is controlled by the CRSRU rapid-quench design; destruction and removal efficiency is verified by third-party analytical at FOAK and post-COD, not asserted from temperature margin alone.
- CRSRU plasma temperature exceeds all common persistent-organic destruction thresholds with margin (see table above). This is not a marginal-compliance case — the operating point sits well above published thermolysis thresholds for the entire regulated persistent-organic list.
- Halogens (F, Cl, Br) become salt-cake products. After CRSRU destruction of halogenated organics, the halogen atoms partition to the aqueous phase as ionic species (F−, Cl−, Br−) and are crystallized in Water MAX as NH4F / CaF2, NH4Cl, and NH4Br respectively. Sulfur becomes (NH4)2S or elemental S. Nitrogen becomes NH4+-salt or N2. Phosphorus becomes phosphate salt.
- Heavy metals become products, not waste. The Metal MAX Processing Train captures the full metals inventory across 9 module classes (EAF steel, hydromet non-ferrous, battery metals, precious metals, REEs, trace metals). Volatile metals (Hg, As, Se, Tl) are captured on self-produced sulfur-impregnated activated-carbon guard beds and recovered via the Trace Metals train (MAX-MTL-008). Non-volatile metals (Pb, Cr, Ni, Cu, Zn, Cd solid fraction, Co, V, Mn, Sn) partition to the OmniCrude™ solid phase and route through Solids Separation into the appropriate Metal MAX stream.
- Cr(VI) is thermodynamically suppressed. The oxygen-starved reducing environment of primary conversion converts any hexavalent chromium to Cr(III) — the non-toxic, non-carcinogenic oxidation state used in leather tanning and stainless-steel production. This is a favorable side-effect of the process regime.
- Analytical verification path. Destruction and Removal Efficiency (DRE) for regulated persistent organics is verified by: (a) accredited third-party laboratory analytical testing on captured-gas, effluent, and residue streams during ASI System Integration Testing (SIT); (b) continuous emissions monitoring (CEMS) post-COD for captured-gas species at the compliance point; (c) periodic composite sampling of MAX product streams to confirm regulated species remain below detection limits or within product-grade specifications. Trade-secret internals (microwave frequency modes, dielectric library, susceptor recipe) are not disclosed pre-COD — verification is by third-party review of post-COD outcome data, not process disclosure.
- Feedstock envelope boundaries are contractual. Radionuclides and cyanide chemistry are excluded from the accepted feedstock envelope by contract. Every site installs radiation portal monitors on the inbound gate. Asbestos-containing feedstock is only accepted at sites qualified under a dedicated HAZMAT protocol and is routed to Glass MAX for vitrification (permanent, non-leaching, fiber-bound immobilization).
- No default disposal path. The system is designed to maximize conversion into certified products and internal recycle streams while minimizing material requiring external disposition — the six MAX Processing Trains are the capture architecture, and all non-product streams are mass-accounted and reported. N2 → industrial N2 product (Gas MAX RC3); CO2 → liquefied CO2 product (Gas MAX RC3); H2O → Recombined Water + condensate products (Water MAX RC1–RC5). The APS enforces a zero-vent design — there is no atmospheric release path in routine operation. There is no ash landfill path, no wastewater discharge path, no incinerator stack. Accidental events (spills, upsets, maintenance operations, exhausted media replacement, edge-case feedstock composition) are not zero and are handled under the national environmental regulator's and national waste-management regulation's standard operator-permit conditions, with licensed HAZMAT contingency for genuinely off-spec fractions.
Regulatory framing. The above is Carbotura's design-basis and reference-thermolysis position. It is not a claim that any specific ACM site is currently permitted for PFAS / dioxin / PCB destruction service under the national waste-management regulation or by the national environmental regulator. Per-site permit scope is determined at operator-license issuance under the national waste-management regulation and is progressively expanded post-COD as third-party analytical verification builds an operating record. Sites qualifying for expanded hazardous-service permits (Category 2/3 HAZMAT classification under the national waste-management regulation) will carry that scope explicitly in their operating license.
Section 4 · Cross-cutting reference
Failure Modes & Upset Scenarios
Routine-operation performance is zero vent by APS design (all captured streams reflow to product); near-zero across waste and discharge. Off-normal events are not zero. This section enumerates the recognized failure modes, the automatic containment response, and the downstream regulatory notification path. All ACM sites operate under the national environmental regulator's and national waste-management regulation's standard operator-permit conditions and carry the corresponding upset-condition reporting obligations.
11 failure modes · containment principles · HAZOP framing
| Failure mode | Trigger conditions | Automatic response | Environmental exposure |
|---|---|---|---|
| Microwave generator fault (single unit) | Magnetron over-temp; power-supply fault; waveguide arc; RF-monitor out-of-envelope | Affected generator islanded within one control cycle; remaining generators on the same Recyclotron™ rebalance load; if quorum lost, Recyclotron™ isolates to hot standby; feedstock feeder to that Recyclotron™ pauses. | No release. Vapor and solid inventories remain contained; sub-atmospheric envelope prevents outward leakage. |
| Recyclotron™ pressure excursion | Feeder over-throw; steam-purge fault; solid bed compaction; vapor-line back-pressure | Feed pauses; N2 flood on affected line; APS captures displaced vapor at the pressure-relief header (routed to Recyclotron™ feed inlet or CRSRU inlet by composition, not vented); pressure return to sub-atmospheric within seconds. | Zero atmospheric release under design conditions. APS is the release path of last resort and routes back to the Recyclotron™ or CRSRU for full reprocessing / destruction. |
| CRSRU trip (plasma flame-out) | Plasma torch fault; quench-boiler over-temp; refractory alarm; vapor-flow interlock | Vapor line isolates upstream at the Recyclotron™ discharge; N2 purge on downstream cyclone; second CRSRU on parallel line takes vapor if capacity permits; failing CRSRU cools under N2 for maintenance. | No release. Any unreformed vapor is held in the isolated line, not vented. Restart under standard hot-restart protocol. |
| PEM fuel-cell stack degradation | Catalyst-poisoning breakthrough (Section 3 Q2); membrane hydration loss; cell-voltage decay past service threshold | Affected stack islanded; power-block load shifted to remaining stacks; H2 flow rebalanced; degraded stack scheduled for membrane / catalyst replacement at next maintenance window; feedstock throughput unaffected (excess H2 returned to H2 buffer storage or re-routed through the H2 PSA for re-polishing; if buffer at capacity, recycled as a controlled reducing / reforming gas into designated CRSRU reactions — not flared and not vented under normal operation). | No release under normal operating conditions — H2 is captured to buffer storage, PSA re-polish, or CRSRU absorption; no routine flaring path exists in the design. Emergency disposition is governed by the site safety case. |
| Activated-carbon guard bed exhaustion | Breakthrough on Hg / As / trace-metal sorbent bed (CEMS or downstream analytical trigger) | Automatic switch to redundant parallel bed; exhausted bed sealed and processed for full material recovery: (1) in-situ thermal desorption → captured metals to Metal MAX Trace Metals stream; (2) desorbed AC substrate (self-produced) returns to the Recyclotron™ feed as carbon-bearing feedstock. If a bed cannot be regenerated in-situ, the whole bed is loaded into the Recyclotron™ feed — CRSRU destroys any residual organics, metals route to Metal MAX, carbon reflows into Carbon MAX. Downstream CEMS values remain within envelope during switch. | No release. Loaded sorbent is never a disposal stream — it becomes feedstock. Metals to Metal MAX; carbon substrate reflows into the process. No HAZMAT disposal path exists in the design. |
| Off-spec feedstock load | Inbound QC / radiation portal monitor / gate composition scan flags feed outside the accepted envelope (Section 2 acceptance protocol) | Load rejected at gate. Rejected load quarantined in sealed containment; returned to shipper with an incident notification filed under the national waste-management regulation; site operating record annotated. | Zero — load never enters the process. Radiation portal is a physical barrier at the inbound gate. |
| Water MAX salt-cake bed capacity | Salt-cake accumulator approaching design capacity; extended run without offtake dispatch | Alarm at 80% capacity, feedstock throttling at 90%, automatic shutdown at 95%. Downstream: dispatch to salt-product customer or licensed storage. | Zero release — the failure mode is throughput limitation, not discharge. |
| Utility loss (grid outage / cooling / instrument air / N2 supply) | External utility interruption | Site is island-capable post-startup: PEM PowerBlock supplies internal load; N2 generation on-site (PSA); cooling water in closed loop; controlled shutdown to hot standby on total loss; startup H2 inventory buffers 4–8 h of critical-load operation. | Zero release. Site rides through short outages; extended outage triggers controlled shutdown to hot standby, not emergency vent. |
| Feedstock feeder mechanical jam | Rag-up / oversized item / feeder-belt fault | Feeder stops; upstream conveyor pauses; Recyclotron™ feed rate ramps down; clearing under lockout/tagout; no unplanned material fall-through to reactor. | Zero release. Feed system is dry and enclosed. |
| Feedstock pre-conditioning fire / smolder | Self-ignition of high-VM feedstock in preparation zone (dust, rag, foam) | Detection: multi-modal (IR + CO + smoke). Response: N2 inertion of the affected bin; feedstock isolation; local fire-brigade notification if not self-extinguishing under N2. | Managed under standard SFPE / NFPA / the host jurisdiction's civil defense code protocols; incident reporting per operator conditions under the national waste-management regulation. |
| Instrumentation failure (CEMS, RF monitor, flow, pressure) | Sensor fault detection; redundancy quorum loss | Redundant sensor takes over; where quorum cannot be established, affected sub-system to safe state; CEMS: dual-train reporting per the national environmental regulator's continuous-monitoring rules. | Zero release from instrumentation cause. CEMS availability reporting is a permit obligation. |
Design principles for containment
- Sub-atmospheric primary envelope. The primary conversion path operates at ~0.5 atm throughout the vapor line. Under any pressure loss or breach the flow direction is inward — ambient air leaks into the envelope, not process gas out. This is a design property, not an active control.
- APS as release-of-last-resort routing to Recyclotron™ or CRSRU. The Atmospheric Protection System captures any displaced vapor at pressure-relief headers and routes it back to the Recyclotron™ feed inlet (for reprocessing through the full conversion path) or to the CRSRU inlet (for direct plasma destruction of any organics), selected by composition — never to vent. This is Carbotura-proprietary and integral to the zero-vent design.
- Redundant parallelism at every critical stage. Two vapor lines × two solid lines × two CRSRUs × multiple MW generators per Recyclotron™ × N-out-of-M redundant guard beds. Single-point failures do not propagate to release.
- Feedstock envelope enforced at the physical gate. Radiation portal monitors, in-gate composition scans, and rejected-load quarantine sit before the process. Excluded feed does not reach the reactor.
- N2 inertion available at every process node. On-site PSA-generated N2 is the universal contingency purge/inertion medium — no external supply dependency.
- Island-capable post-startup. Once running, the site does not depend on grid, external N2, or external steam. There is no routine external process-water demand once stable Island-Mode operation is established (subject to FOAK verification); commissioning fill, firewater, and potable / sanitary supplies are separate utility categories. Loss of external utility triggers controlled hot-standby, not emergency vent.
- Standard national environmental-regulator and waste-management-regulation upset reporting. Every recognized failure mode has a defined severity classification and reporting obligation. Post-COD annotated operating record is shared with the counterparty and the relevant authority per permit conditions.
Framing. The above enumerates recognized failure modes at design-basis level. It is not a HAZOP report. Formal HAZOP, LOPA, and SIL classification are conducted at ASI System Integration Testing (SIT) per site and are shared with the counterparty and the host jurisdiction's permit authority under standard confidentiality protocols. This portal shows the operational envelope; the safety-case-of-record is a document deliverable at pre-COD.
Section 4 · Question 1
the counterparty's question
“What are the continuous air emission levels for the facility, and how do they compare directly to local environmental standards?”
Response
Every ACM deployment is designed to meet or exceed the applicable regulatory framework in the host jurisdiction: the national environmental regulator's standards, the national waste-management regulation's requirements, and any special economic zone or host-site industrial authority's additional requirements. Continuous emissions monitoring (CEMS) is installed at every site as standard specification.
Engineering Detail
Design-basis emission envelopes vs. reference standards (per 100 TPD module, ESTIMATED — design-basis pending site CEMS validation):
| Species | Design Envelope | Ref Standard (the national environmental regulator / EU BAT-BREF equiv) |
|---|---|---|
| CO2 (net) | Feedstock-carbon-neutral (biogenic) | — |
| NOx | < 100 mg/Nm³ | 150 mg/Nm³ |
| SOx | < 30 mg/Nm³ | 50 mg/Nm³ |

| Dioxins/furans | < 0.05 ng TEQ/Nm³ | 0.1 ng TEQ/Nm³ |
Actual CEMS data (post-COD) available directly to the counterparty and the relevant host-jurisdiction authority under standard regulatory reporting protocols.
Section 4 · Question 2
the counterparty's question
“How much process wastewater (condensate) is generated, what is its chemical makeup, and how is it treated to meet local discharge standards?”
Response
The ACM plant requires no external process water. Startup uses ~2 tons of H2 to generate the internal water inventory (~17.9 t via PEM stoichiometry). Post-startup, water is internally circulated and the site is net water-producing.
Two water streams are managed separately:
- Recombined Water — the largest fraction. H2O synthesized directly from H2 + O2 recombination in the PEM PowerBlock (2 H2 + O2 → 2 H2O; ~4,085–5,871 kg/h at the illustrative operating cases). Because Recombined Water is synthesized from elemental gases and never contacts feedstock or process streams, it carries synthesis-derived purity. Targeted delivery is RC4/RC5 grade water product (semiconductor-grade, pharma-grade WFI) or internal reuse — final grades pending stack-materials / balance-of-plant analytical qualification at FOAK.
- Process condensate — ~1,519 kg/h at 100 TPD from primary conversion + CRSRU quench + syngas cleanup. Routed to the Water MAX Processing Train and delivered as water products at RC1 (potable minimum) through RC5 (pharma-WFI). Feedstock-borne chlorine / sulfur / nitrogen contaminants crystallize in Water MAX as salt cake product (~50.7 kg/h dry basis, NH4Cl + (NH4)2S at 100 TPD).
Water balance · interactive Sankey
Illustrative midpoint case at 100 TPD: 4,977 kg/h Recombined + 1,519 kg/h condensate = 6,496 kg/h total. All flow lands as product (RC1–RC5), salt cake, internal reuse, or community surplus — nothing to environmental discharge.
Near-zero discharge — all water is a product by design. Routine operations are designed for zero environmental discharge. Finished Water MAX product is designed to meet at least the applicable potable-water standard after treatment, analytical release, and certification — even RC1 baseline targets meet-or-beat the national environmental regulator's drinking-water standards and comparable regional benchmarks; intermediate streams (raw condensate, quench water, pre-polish fuel-cell water) are not represented as potable. Higher RC grades (RC2 industrial-DI, RC3 softened / distilled, RC4 semiconductor, RC5 pharma-WFI / ultra-pure) are engineered upgrades from the potable baseline. Recombined Water (from PEM) carries synthesis-derived purity targeting RC4/RC5; final grade qualification (including any polishing requirement) is verified analytically at FOAK. Accidental events (spills, upsets, maintenance operations, equipment failure) are not zero and are managed under the national environmental regulator's standard operator-permit conditions. The national environmental regulator's discharge limits below function as design ceilings for internal water quality as well as fallback thresholds for any inadvertent release event. Where a site's water balance runs surplus beyond internal reuse and salable water grades, that surplus is delivered as clean water to the community (see Community Augmentation callout on landing) — never as environmental discharge in routine operation.
Engineering Detail
Wastewater profile by stage:
- Total volume: typical 3–8 m³ / tonne of feedstock, feedstock-dependent.
- Composition ranges (pre-treatment):
- COD: 500–3,000 mg/L
- Total suspended solids: 100–500 mg/L
- Heavy metals (Cd, Cr, Cu, Ni, Pb, Zn): individual species below the host jurisdiction's regulatory limits pre-treatment for most feedstocks; targeted removal for specific streams
- Chloride: 500–2,500 mg/L
- Ammonia-N: 50–300 mg/L
- Treatment train: physical separation → chemical precipitation → biological polish → membrane final polish → delivery as RC1–RC5 water product (see Water MAX split above); no environmental discharge route in routine operation.
- Design ceiling: the national environmental regulator's industrial effluent standard functions as an internal water-quality ceiling (not a release target); the plant exceeds requirement in most parameters even though no discharge occurs.
- Fuel-cell water (separate from condensate): the PEM PowerBlock additionally generates ~4,085–5,871 kg/h of water from H2 + O2 (see Section 1 Q2 Boundary C). This is a clean product / reuse stream (repository
water_fcslate = 34 t/d recovered), not process wastewater, and reinforces that the site is a net water producer rather than a net discharger. Recovery route, purity grades, and any surplus disposition confirmed by OEM data and the site water plan.
Zero untreated discharge. Zero contact with regional groundwater. All facilities are engineered as sealed-basin containment per Carbotura's standard site-engineering practice.
Section 4 · Question 3
the counterparty's question
“Is the remaining solid ash or char classified as hazardous waste, or does it meet local standards for safe disposal or commercial reuse?”
Response
The ACM produces near-zero waste solids in routine operation. All routine solid outputs are products routed through the Regenesis MAX™ zone. The Recyclotron™ output (OmniCrude™ solid phase) enters Solids Separation and splits into four fractions, each routed to its dedicated MAX Processing Train:
- Carbon → Carbon MAX Processing Train → RC1–RC5 products (activated C, thermal black, graphite, CNT, fullerenes)
- Glass → Glass MAX Processing Train → RC1–RC5 products (container, boro, fiber, ultra-pure specialty)
- Metals → Metal MAX Processing Train → RC1–RC5 products (EAF steel + hydrometallurgical non-ferrous + REE + precious metals + trace metals)
- Inerts → recirculated to the Recyclotron™ as microwave susceptor (closed loop, not a waste stream)
There is no default disposal path in routine operation. Design intent is near-100% material recovery across the four fractions. Accidental events (maintenance operations, spent-media replacement, sorbent exhaustion, edge-case feedstock composition) are not zero and are handled under the national waste-management regulation's standard operator-license conditions, with licensed HAZMAT contingency for genuinely off-spec fractions. The historic terms “ash” and “char” are legacy catch-alls from combustion/incineration doctrine and do not describe this domain (see OmniCrude™ framing in Section 1). Where a specific site's feedstock generates unusual fractions, the decision is a product-routing decision (which MAX train / which RC grade / market-timing hold) — not a disposal decision. The waste-classification framework under the national waste-management regulation below is honored via routing to appropriate MAX modules; hazardous-stream contingency handling exists for edge cases but is not the design default.
Engineering Detail
Residue framework:
- Volume: 10–25% of feedstock input by mass, feedstock-dependent.
- Classification protocol: TCLP (Toxicity Characteristic Leaching Procedure) per feedstock-batch basis.
- Expected classification by feedstock class:
- MSW and industrial hydrocarbon residues: predominantly non-hazardous ash suitable for cement / concrete supplementation.
- WEEE and specific industrial streams: mineral-rich fractions targeted for critical-minerals recovery (REE, Ga, In routing where economical).
- Ash and char: reuse pathways include cement kiln substitution, road base, mineral recovery.
- HAZMAT exception: <5% of typical annual volume, licensed transport + landfill under contract.
Note: LLRP (legacy-landfill remediation via the future Exogenesis™ Protocol) is out of scope for this Technical Assessment — see landing scope note. Legacy-landfill residues, when addressed, are separately characterized — excavated legacy landfill mining produces different residue chemistry than fresh MSW conversion.
