What this document is
The fiscal, economic, and structural delta between State A (current open-dumping-dependent system) and State B (Circular Advantage deployment under the Circular Supply Agreement).
- State A carries a decided legal exposure — the Supreme Court has ruled the underlying practice unlawful.
- State B eliminates that exposure at the priority site while generating a new sovereign royalty stream, at zero capital cost.
- Where local cost data doesn't exist, this report says so — the fiscal case rests on capex avoidance and royalty income, not a fabricated cost comparison.

Economic Impact Report
State B (CSA deployment) eliminates the Meethotamulla-class legal exposure at Karadiyana while generating a Circular Royalty™ of ~$11.32M/year from Year 2 at Phase Initial scale — at zero government capital cost, against a separate ~$9.35M/year Beneficiation Fee obligation and a State A with no cost ceiling and a decided court finding against it.
Inherited Confidence Flags — Carried from Waste Study and Proposal
- Western Province generation (~3,500 TPD) — VERIFIED: Self-reported by the Waste Management Authority, Western Province. Does not affect Phase Initial sizing.
- Karadiyana receipt volume (~500 TPD) — VERIFIED, NBRO-flagged: Directly anchors Phase Initial sizing.
- Disposal cost — DATA GAP: No current published local fee schedule. The Beneficiation Fee (TMC Fee) is set at $50/ton, below the canon standard range, from Carbotura's standard parameters rather than a local anchor.
- Site candidates — provisional: No site control, permitting, or land agreement has been executed.
- Employment and economic impact figures — estimated: Scaled from Carbotura standard parameters. Not project-specific.
- Meethotamulla Supreme Court ruling — VERIFIED: 31 March 2026, public record. The only fully VERIFIED regulatory input in this report.
Introduction and Decision Summary
§1.1 — What This Report Measures
This report quantifies the fiscal, economic, and structural delta between two states: State A (current system — feedstock continuing to Karadiyana and comparable open dumpsites, at legal risk following the Meethotamulla ruling) and State B (Circular Advantage deployment — ACM facility receiving the crisis-priority feedstock under a perpetual CSA — with Circular Royalty™ payments beginning 13 months after the corresponding Beneficiation Fee payment).
§1.2 — Decision Summary Table
| Element | State A (Current System) | State B (With Carbotura) | Difference |
|---|---|---|---|
| Legal exposure (open dumping practice) | Ruled unlawful at Meethotamulla (31 Mar 2026); Karadiyana carries the same NBRO-flagged risk profile | Compliant manufacturing classification under BOI framework | Legal exposure eliminated at priority site |
| Government capital obligation | Undetermined — new landfill or WtE capacity would require significant capex | Zero | $305M–$2.03B capex avoided |
| Government revenue (Circular Royalty™) | $0 | $11.32M/yr from Year 2 (Phase Initial) | +$11.32M/yr new revenue |
| Government fee obligation (Beneficiation Fee) | $0 | $9.13M/yr from Year 1 (Phase Initial) | New $9.13M/yr cost — separate transaction, never netted against royalty |
| Key data gaps | No current published per-ton disposal-cost figure; Colombo South Waste Processing Facility (Fairway) current status unconfirmed | ||
| Decision window | Now — following the Meethotamulla ruling and before a comparable finding is sought for Karadiyana. | ||
This Economic Impact Report models the Delta under the Circular Supply Agreement (CSA) — Beneficiation Fee (TMC Fee) plus Circular Royalty™, Carbotura's single commercial structure — see Proposal §1.5 and §4.0 for the full commercial structure.
§1.3 — Fiscal vs. Regional Economic Separation
State A Baseline — Current System
§2.1 — Feedstock Volume and Disposition
| Stream | TPD | Current Destination | Status | Source |
|---|---|---|---|---|
| Karadiyana-routed municipal waste | 500 | Karadiyana Landfill — over capacity, NBRO-flagged | VERIFIED | NBRO / WMA-WP |
| Western Province total generation | 3,500 | Mixed — Karadiyana, Kerawalapitiya WtE (700 TPD), dumpsites | VERIFIED | WMA-WP |
| Kerawalapitiya WtE (existing, not displaced) | 700 | Operational under 20-yr agreement — not addressed by this proposal | VERIFIED | Aitken Spence PLC |
§2.2 — State A Legal and Structural Position
State A's defining feature is not a cost trajectory but a legal one: the Supreme Court has ruled that the open-dumping practice comparable sites employ is unlawful. Karadiyana operates under NBRO-documented conditions comparable to pre-collapse Meethotamulla. No engineered alternative currently absorbs this volume at compliant scale — the stalled Colombo South Waste Processing Facility (Fairway) remains of unconfirmed status.
State B Deployment
State B deploys a 500 TPD Phase Initial ACM facility under the CSA: the Government pays the Beneficiation Fee and provides site access; Carbotura finances, builds, owns, and operates the facility; the Government receives the Circular Royalty™ back beginning 13 months after the corresponding Beneficiation Fee payment.
| Year | Circular Royalty™ Rate | Annual (182,500 TPY) |
|---|---|---|
| 1 | $0 (pre-royalty) | $0 |
| 2 | $62.01/ton | $11,316,825 |
| 10 | $80.55/ton | $14,700,375 |
| 30 | $152.46/ton | $27,823,950 |
Delta Analysis
| Metric | Phase Initial (500 TPD) | Phase Expanded (3,500 TPD) |
|---|---|---|
| State A capital obligation (if government builds capacity) | Not quantified — no verified reference project cost | Not quantified |
| State B Carbotura CapEx (avoided by government) | $305M | $2,030M |
| Circular Royalty™ Year 2 | $11.32M/yr | $79.22M/yr |
| Circular Royalty™ Year 30 | $27.82M/yr | $194.77M/yr |
System Impact

| Direct FTE employment | ~175 | ~1,225 | ESTIMATED |
| Carbon avoided | ~315,000 tCO₂e/yr | ~2,205,000 tCO₂e/yr | ESTIMATED |
| Landfill volume diverted from Karadiyana | 182,500 TPY | 1,277,500 TPY | ESTIMATED |
Risk and Sensitivity
| Scenario | Volume (TPD) | Circular Royalty™ Y2 ($M) |
|---|---|---|
| Base (500 TPD) | 500 | $11.32 |
| −20% (400 TPD) | 400 | $9.05 |
| +20% (600 TPD) | 600 | $13.58 |
Decision Window Analysis
§7.1 — Binding Constraints
- Meethotamulla Supreme Court ruling (decided, 31 Mar 2026): Establishes a legal precedent applicable to every comparable open-dumping site, including Karadiyana.
- Karadiyana NBRO risk finding: Independent engineering assessment already places Karadiyana in the same risk category as pre-collapse Meethotamulla.
- No confirmed engineered alternative at scale: The stalled Colombo South Waste Processing Facility leaves an unaddressed gap.

§8.1 — Fiscal Effects, Reported Separately
| Period | Circular Royalty™ Received | Beneficiation Fee Paid |
|---|---|---|
| Year 1 (pre-royalty) | $0 | $9,125,000 |
| Year 2 | $11,316,825 | $9,353,125 |
| Year 30 | $27,823,950 | $18,673,400 |
Royalty figures are amounts received. The royalty is paid 13 months in arrears, so the figure shown for a year is earned on the previous year’s delivered tonnage.රජකීය අගයන් යනු ලබු මුදල් වේ. රජකීයය මාස 13ක පමාවෙන් ගෙවනු ලැබේ, එබැවින් වර්ෂයක් සඳහා පෙන්වා ඇති අගය පෙර වර්ෂයේ බෙදා හරින ලද ටොන් ගණන මත උපයනු ලැබේ.
Executive Implications — EIR Summary
- State A carries a decided legal finding against it. Not a risk scenario — a court has already ruled.
- State B eliminates that exposure at zero capital cost while generating $11.32M/yr in Circular Royalty™ from Year 2 (against a separate $9.35M/yr Beneficiation Fee obligation from Year 1, never netted). Phase Initial alone delivers ~$535.2M in Circular Royalty™ over 30 years, against ~$400.6M in Beneficiation Fee paid over the same period.
- This report does not invent a State A capital-cost comparator where none is publicly verifiable. The case for State B stands on its own quantified terms.
Appendix A — Sources and Methodology
Methodology Notes
- Circular Royalty™ formula: 120%→150% multiplier (121% Year 2 → 149% Year 30) on current-year Beneficiation Fee ($50/ton Year 1, +2.5%/yr), 13-month lag from corresponding fee payment. Carbotura standard parameters.
- Phase sizing: Phase Initial = Karadiyana current receipt (~500 TPD). Phase Expanded = Western Province total generation (~3,500 TPD).
- CapEx: $75M first 100 TPD module + $57.5M × (N−1) additional modules.
- Employment and environmental performance: Carbotura standard parameters scaled to TPD. Not project-specific.
- No State A capital-cost figure: No publicly verifiable reference project cost found for a government-built alternative in Sri Lanka.
