PRRS (Plasma Resource Recovery System) — Exhaustive Deep Dive

Research date: 2026-03-03 Purpose: Complete technical profile of The Claw's chosen processing technology — PyroGenesis's waste-to-energy plasma system. Status: This is the selected technology direction for The Claw. Everything here matters.

1. What PRRS Is

PRRS = Plasma Resource Recovery System. It is PyroGenesis Canada's waste-to-energy system. Unlike PAWDS (which only destroys waste), PRRS captures the syngas output and converts it to electricity, heat, and liquid fuels.

Think of it this way:

PAWDS = plasma trash incinerator (waste goes in, nothing useful comes out)
PRRS = plasma power plant (waste goes in, electricity + fuel comes out)

For The Claw, which must power itself from the plastic it collects, PRRS is the relevant technology. PAWDS proved plasma works at sea; PRRS adds the energy recovery that makes self-sustaining operation possible.

How It Relates to Other Knowledge Base Entries

Document	Relationship
PyroGenesis PAWDS Deep Dive	PAWDS = the marine-proven predecessor. PRRS builds on the same torch technology.
Plasma Gasification Process	The underlying science. PRRS is a specific commercial implementation.
Syngas	PRRS's primary output. Syngas composition, downstream uses.
Energy Balance	The energy math. Does PRRS produce more energy than it consumes?
Processing Technology Selection	The decision document that chose PRRS over InEnTec PEM.

2. The Two-Step Process

PRRS uses a proprietary two-step plasma gasification process. This is fundamentally different from PAWDS's single-step destruction.

Step 1: Primary Gasification — Graphite Arc Plasma Furnace

Unsorted waste is fed into a DC electric arc furnace using graphite electrodes. This is conceptually similar to the electric arc furnaces (EAFs) used in steelmaking — a proven industrial technology at scales of hundreds of tonnes per day.

How it works: 1. Waste enters the furnace from above 2. Graphite electrodes create a transferred DC arc — the arc passes directly through the waste and slag bath 3. The molten slag becomes a conductive pathway for the arc current 4. The slag acts as a resistive heating element — converting electrical energy to thermal energy with high efficiency 5. At temperatures above 1,500°C, all organic matter gasifies into CO and H₂ (syngas) 6. Inorganic matter melts and pools at the bottom as liquid slag and liquid metal 7. Slag and metal are periodically tapped from separate outlets

Why graphite electrodes matter:

Feature	Graphite Arc (PRRS)	Refractory-Lined (InEnTec, AlterNRG, etc.)
Liner material	Graphite (no refractory bricks)	Refractory brick/ceramic
Maintenance	Electrode replacement (consumable, planned)	Refractory repair (unpredictable, expensive)
Ship motion tolerance	Graphite is mechanically robust	Refractory cracks from vibration/thermal cycling
Temperature uniformity	Arc directly heats slag bath	Hot spots near torch, cold spots elsewhere
Energy transfer	Direct (resistive heating through slag)	Indirect (radiant/convective from torch plume)
Scale-up risk	Similar to industrial EAFs (well understood)	This is the failure mode that killed AlterNRG, Europlasma, and Plasco

The absence of refractory is PRRS's single most important engineering advantage. Every major plasma gasification failure at commercial scale traces back to refractory degradation.

Step 2: Secondary Gasification — Air Plasma Torch (APT)

An Air Plasma Torch (APT) completes the gasification of any residual organic material in the syngas stream.

Parameter	Value
Torch power	200 kW (DC), standard APT
Plume temperature	>5,000°C
Arc type	Non-transferred (torch self-contained)
Plasma-forming gas	Air (no exotic gases)
Electrode life	>1,000 hours continuous

The APT ensures complete destruction of tars, complex hydrocarbons, and any organics that survived the primary furnace. The result is a clean syngas stream of primarily CO, H₂, CO₂, and N₂.

Step 3: Rapid Quench

After secondary gasification, the syngas is immediately quenched with water from 1,100°C to below 100°C in less than half a second.

This rapid cooling is critical because dioxins and furans — the carcinogenic compounds that plague conventional incinerators — form in the 200–500°C temperature window. By quenching through this range in under 0.5 seconds, PRRS prevents their formation entirely.

Published test results (PyroGenesis Venice 2006 paper):

Dioxins/furans: 10x below air emission standards
Acid gases (HCl, HF): 300x below standards

Complete Process Flow

Raw waste (unsorted)
  → Feed system (hopper, conveyor)
  → Step 1: Graphite arc plasma furnace (>1,500°C)
      → Organic fraction → syngas (CO + H₂)
      → Inorganic fraction → molten slag + molten metal
  → Step 2: APT secondary gasifier (5,000°C)
      → Destroys residual tars/organics in syngas
  → Step 3: Water quench (1,100°C → <100°C in <0.5s)
      → Prevents dioxin/furan formation
  → Gas cleaning (HCl, H₂S, dust, heavy metals removed)
  → Clean syngas → gas engine/turbine → electricity
  → Waste heat → ORC → additional electricity
  → Slag tapping → vitrified aggregate (inert, non-leaching)
  → Metal tapping → recycled metal ingots

3. Technical Specifications

Throughput

Scale	Capacity	Notes
Minimum module	1 TPD	Small-scale / pilot
Standard module	10–50 TPD	Municipal / industrial
Maximum module	100 TPD	Largest single module offered
Multi-module	No stated limit	Multiple 100 TPD modules in parallel

For The Claw Phase 1 (5–10 TPD target), a single small PRRS module would suffice. Phase 2+ (50–100 TPD) would use a full-size module.

Operating Temperatures

Location	Temperature
Graphite arc furnace	>1,500°C (slag bath)
APT plasma plume	>5,000°C
Syngas pre-quench	~1,100°C
Syngas post-quench	<100°C
ORC waste heat capture	90–150°C

Syngas Composition (Pilot Test Data)

From the 2009 IT3 paper "Validation of the Plasma Resource Recovery System (PRRS) Simulations":

Component	Pilot Test	Model Prediction
CO	20.6 ± 1.0%	22.2%
CO₂	5.4 ± 0.5%	6.7%
H₂	~15%	—
N₂	~55% (balance)	—

Syngas production rate: 2.12 ± 0.2 standard cubic meters per kg of MSW fed.

Important caveat for The Claw: This data is from MSW (municipal solid waste). Ocean plastic (predominantly PE/PP) would produce different syngas composition — likely higher CO and H₂ content due to higher carbon and hydrogen content in plastics, and lower N₂ if oxygen-enriched gasification is used. No published data exists for PRRS processing plastic feedstock specifically.

Outputs

Output	Description	Use
Syngas	CO + H₂ rich fuel gas	Gas engine/turbine → electricity
Electricity	Via ICE or gas turbine from syngas	Powers the ship/platform
Steam/hot water	Waste heat recovery	Process heat, preheating, ORC
Methanol	Synthesized from syngas (planned for EU contract)	Liquid fuel, chemical feedstock
Vitrified slag	Glass-like solid from inorganic fraction	Construction aggregate, ballast
Recovered metals	Separated from slag at tapping	Recycling revenue

Feedstock Tolerance

Waste Type	Handled?
Municipal solid waste (unsorted)	YES
Industrial waste	YES
Hazardous waste (liquid, solid, sludge)	YES
Biomedical waste	YES
Plastics (all types including PVC)	YES (patent addresses chlorinated plastics)
Wet waste (30–45% moisture)	YES (modeled)

4. The Hurlburt Field Installation — The Only One Ever Built

Overview

The only PRRS installation ever constructed. Located at Hurlburt Field, a US Air Force base near Fort Walton Beach, Florida, home of Air Force Special Operations Command (AFSOC).

Key Facts

Field	Detail
Official name	Transportable Plasma Waste to Energy System (TPWES)
Location	Hurlburt Field, Fort Walton Beach, FL
Client	US Air Force Special Operations Command (AFSOC)
Builder	PyroGenesis Canada Inc. (turnkey)
Design capacity	10.5 metric tonnes per day
Annual throughput	~3,100 tonnes/year
Power output	420 kW (via internal combustion engine on syngas)
Construction cost	$7.4 million
Scope	Full turnkey: site preparation, building, infrastructure, equipment, environmental permitting
Stakeholders	US DoD, USAF Surgeon General, Canadian/Quebec governments, Gulf Power Company

Timeline

Date	Milestone
Pre-2010	Design and construction
Late 2010	System becomes operational
April 26, 2011	Official inauguration by AFSOC
June 2011	Formal acceptance by USAF
May 2013	Closed and sold at government liquidation auction

What It Proved

1. PRRS can process unsorted waste (MSW, biomedical, hazardous) at ~8.5 TPD 2. Syngas can power an internal combustion engine generating 420 kW returned to the base grid 3. A North American first: plasma gasification producing grid electricity from waste 4. Full environmental permitting was achieved (Florida DEP) 5. The system was accepted by USAF after formal evaluation

What It Didn't Prove

1. Long-term reliability — operated only ~2 years before closure 2. Net energy balance — the 420 kW is gross output; parasitic loads (torch power, fans, pumps, gas cleaning) are unknown. Was it net-positive? 3. Plastic feedstock — processed MSW, not plastic specifically 4. Marine operation — land-based only 5. Scale-up — 8.5 TPD is small; The Claw needs 10–100x more

The Closure — The Uncomfortable Question

Hurlburt Field was closed in May 2013 and the equipment auctioned. PyroGenesis has never publicly explained why. Their website still lists it as a reference project without mentioning the closure.

Possible explanations (unconfirmed):

2013 federal sequestration — automatic budget cuts across DoD; many non-essential projects were cut
Operational issues — the system may have had reliability problems that aren't publicly documented
Cost overruns — operating costs may have exceeded the value of electricity generated
Technology demonstration complete — the USAF may have gotten what it needed (proof of concept) and had no mandate to continue operations

For The Claw, this matters. The only PRRS ever built ran for ~2 years and was shut down. We don't know if it was shut down because it worked (mission complete) or because it didn't work well enough. This is the single biggest uncertainty in the PRRS technology assessment.

Mitigation: Phase 1 of The Claw is specifically designed to validate the technology at small scale (5–10 TPD) before committing to larger investment. If PRRS doesn't perform, we find out during Phase 1, not after spending $200M.

5. Energy Recovery System

Electricity from Syngas

At Hurlburt Field, syngas was fed to an internal combustion engine (ICE) producing 420 kW. At larger scale, a gas turbine or combined cycle would be used for higher efficiency.

Engine Type	Typical Efficiency	Best For
ICE (reciprocating)	30–38%	Small scale (<5 MW), variable load
Gas turbine	25–35%	Medium scale (5–50 MW), steady load
Combined cycle (GT + steam)	40–55%	Large scale (>50 MW)
Fuel cell (SOFC)	45–60%	Future option, not yet proven on syngas at scale

For The Claw Phase 1 (5–10 TPD, ~1–3 MW electrical), a syngas-compatible ICE (Jenbacher, GE Waukesha) is the proven choice.

Waste Heat Recovery via ORC (Patent US 9,447,705)

PyroGenesis holds a US patent specifically on maximizing energy recovery from plasma gasification using an Organic Rankine Cycle (ORC):

Parameter	Value
ORC operating temperature	90–150°C
Working fluid	R245fa (preferred)
Thermal-to-electrical efficiency	~10%
Recoverable waste heat	Up to 20% of total system energy rating
Heat sources	Torch cooling (5%), chamber cooling jackets (15%), exhaust
Torch waste heat	Up to 35% of gross power supplied to torch
Heat transfer fluids	Water (<100°C), ethylene glycol, thermal oils
Surface temperature	≤60°C outer surface (IMO maritime regulation)

Key detail: The patent explicitly specifies the IMO 60°C surface temperature limit, indicating PyroGenesis designed this system with potential marine applications in mind from the start.

Energy Balance for Ocean Plastic (Theoretical)

Ocean plastic is a far better feedstock than MSW for energy recovery:

Feedstock	Calorific Value	Moisture	Ash/Inorganic
MSW (typical)	~10 MJ/kg	30–45%	15–25%
Ocean plastic (PE/PP)	~30–40 MJ/kg	Low (pre-dried)	<5% (salt, biofouling)

Rough energy balance at 10 TPD ocean plastic:

Energy Flow	Value
Energy in feedstock	10,000 kg × 35 MJ/kg = 350 GJ/day = ~4 MW thermal
Plasma torch input	~0.3–0.5 MW electrical
Syngas energy (60–70% recovery)	~2.4–2.8 MW thermal
Electrical generation (35% efficiency)	~0.8–1.0 MW electrical
ORC additional recovery	~0.05–0.1 MW electrical
Parasitic loads (pumps, fans, cleaning)	~0.1–0.2 MW electrical
Net electrical surplus	~0.5–0.8 MW

At 100 TPD:

Energy Flow	Value
Energy in feedstock	~40 MW thermal
Torch input	~2–5 MW electrical
Syngas energy	~24–28 MW thermal
Electrical generation	~8–10 MW electrical
ORC recovery	~0.5–1.0 MW electrical
Parasitic loads	~1–2 MW electrical
Net electrical surplus	~5–8 MW

Critical caveat: These are theoretical calculations. No PRRS has ever processed ocean plastic. The Hurlburt Field system's net energy balance was never published. Phase 1 exists to validate these numbers.

6. European Contract — Status and Significance

The Original Contract (July 2024)

Field	Detail
Announced	July 2024
Client	European consortium (name confidential)
Phase 1 value	~$2 million (EUR 1.3M)
Phase 1 scope	Conceptual and preliminary design, feasibility, cost estimation
Phase 1 timeline	~1 year (Q3 2024 → Q3 2025)
Phase 2 estimate	$120–160 million (EUR 80–105M)
Phase 2 scope	Full construction of PRRS waste-to-energy facility
Planned outputs	Syngas, methanol, electricity, heat, slag, metals

Current Status: ON HOLD

As of Q4 2024, the client lost its first-stage financing. The $2M was removed from PyroGenesis's reported backlog. The client is seeking alternative funding. The project is paused.

For The Claw: This is both bad news and an opportunity. Bad: it means PRRS still has no active large-scale project. Good: it means PyroGenesis would be highly motivated to partner on The Claw as their flagship PRRS project.

Other Recent European Contracts

Contract	Value	Client	Date	Scope
Plastic waste processing	EUR 379K (~$600K)	Major EU environmental services co.	July 2025	Engineering + testing for non-recyclable plastics
Radioactive waste	Undisclosed	EU nuclear decommissioning org	December 2025	Design phase for low-level radioactive waste plasma furnace

The plastic waste contract is particularly relevant — it demonstrates commercial demand for plasma processing of non-recyclable plastic in Europe, driven by the EU's EUR 800/tonne levy on unrecycled plastic packaging waste.

7. Marinizing PRRS — What Would It Take?

PRRS is not marine-certified. Only PAWDS holds Lloyd's Register MED Type Approval. Putting PRRS on The Claw requires significant marine engineering work.

What Needs to Change

Requirement	Difficulty	Notes
Classification society approval (LR, DNV, ABS)	High	1–2 years of testing and documentation
MARPOL Annex VI compliance (air emissions)	Medium	Syngas combustion is cleaner than diesel; should pass
Ship motion tolerance — graphite electrodes	Medium	Maintain electrode gap under vibration; damping mounts
Ship motion tolerance — molten slag pool	HIGH	>1,500°C liquid sloshing under wave motion. Never tested.
Slag tapping at sea	HIGH	Draining molten material at >1,500°C on a moving vessel
Syngas handling (marine grade)	Medium	CO + H₂ gas is toxic and explosive; marine gas handling standards exist
Seawater cooling system	Low	Standard marine engineering
Corrosion resistance	Medium	Salt air, humidity, splash zone
Surface temperatures ≤60°C	Low	Already designed into the ORC patent
Fire suppression	Medium	Standard marine fire systems
Electrical safety (marine grade)	Medium	Standard marine electrical standards

The Two Big Unknowns

1. Molten slag under motion. The PRRS primary furnace maintains a pool of molten slag at >1,500°C that acts as the conductive pathway for the DC arc. On land, this pool is stable. At sea, even on a large ship, wave motion could cause:

Slag sloshing against furnace walls
Uneven heating as the conductive path shifts
Arc instability as the slag surface moves
Potential for slag to contact and damage electrodes
Hazardous conditions during slag tapping

A mobile processing ship (The Claw's chosen architecture) has more motion than a semi-submersible platform. However, an Aframax-class tanker in the relatively calm GPGP may have acceptably low motion.

Mitigation: Design a deeper, narrower slag pool to reduce sloshing. Use baffles. Operate in calm conditions (GPGP is relatively calm). Test at small scale first.

2. Electrode alignment under vibration. The graphite arc requires precise electrode spacing. Vibration from ship engines and wave motion could affect arc stability.

Mitigation: Vibration-damped mounting. Automated electrode gap control (standard in industrial EAFs). The 200 kW APT (Step 2) already works at sea on PAWDS — it's the primary furnace arc that's unproven.

The PAWDS-PRRS Hybrid Strategy

The optimal approach for The Claw may be to combine PAWDS marine engineering with PRRS energy recovery:

Component	Source
Marine-grade enclosure, mounting, vibration damping	PAWDS design principles
No-refractory reactor design	Both PAWDS and PRRS share this
APT plasma torch (secondary gasifier)	Identical technology in both systems
Syngas capture and gas cleaning	PRRS design
Electricity generation (ICE on syngas)	PRRS Hurlburt Field proven
ORC waste heat recovery	PRRS patent
One-button operation, rapid start/stop	PAWDS proven feature
Classification society certification	PAWDS has Lloyd's; extend to PRRS variant

This is exactly what the Processing Technology Selection decision document recommends: a marinized PRRS module incorporating PAWDS marine design principles.

8. Competitive Landscape — Why PRRS Over Alternatives

The Plasma Waste-to-Energy Graveyard

The industry has a catastrophic track record at commercial scale:

Company	Project	Scale	Investment	Outcome
AlterNRG / Westinghouse	Teesside, UK	2× ~50 MW	~$1 billion	Total failure. Air Products wrote off $0.9–1.0B. AlterNRG receivership 2021.
Europlasma	Morcenx, France	150 TPD	€50M+	WtE failed. Pivoted to asbestos destruction only.
Plasco Energy	Ottawa, Canada	85 TPD	CA$80M+	Bankruptcy 2015. Never achieved sustained commercial operation.
InEnTec	Various US	Small scale	$230M+ funding	2 US plants closed due to technical issues. 13 systems deployed globally but mostly pilot/demo scale.
Sierra Energy	Fort Hunter Liggett	20 TPD pilot	Unknown	Testing began 2020; no published results since. Not plasma (blast furnace).

The common thread in every failure: refractory degradation at scale. Corrosion, thermal cycling, and mechanical stress destroy refractory linings. Maintenance costs spiral. Uptime collapses. Economics fail.

Why PRRS Is Different

PRRS uses graphite electrodes in a transferred arc configuration — no refractory. The graphite electrodes are consumable (planned replacement), not structural. The slag pool IS the reactor lining (it solidifies on the walls as a protective skull).

This is the same principle used in electric arc steelmaking, which operates worldwide at scales of hundreds of tonnes per day with high reliability.

Head-to-Head Comparison

Feature	PRRS	InEnTec PEM	Sierra FastOx	AlterNRG
Refractory-free	YES	No	N/A (blast furnace)	No
Marine-related tech	YES (PAWDS)	No	No	No
Max throughput/module	100 TPD	125 TPD	2,000 TPD (claimed)	250 TPD (never achieved)
Proven at sea	Related (PAWDS)	No	No	No
Net power (per TPH MSW)	420 kW at 8.5 TPD	1.0–1.4 MW (claimed)	Not published	Never operational
H₂ production	Possible from syngas	YES (1,500 kg/day)	Possible	Never operational
Operational status	1 closed installation	13 systems (mostly pilot)	1 pilot (no results)	DEAD
PCB destruction	Not specified	99.99999999%	Not specified	N/A
Company status	Fragile ($3M cash)	Private, 29 employees	Private	Receivership

InEnTec — Why It Was Eliminated

InEnTec PEM was the other serious contender. It was eliminated because: 1. No marine experience whatsoever — never been on a ship 2. Refractory-lined — the #1 failure mode in plasma gasification 3. Molten glass bath — 1,400°C liquid glass would slosh catastrophically under ship motion 4. SeaChange partnership stalled — the one marine concept using PEM has been dormant since 2020 5. Tiny company — 29 employees, no manufacturing capability for marine-grade systems

1. ORC energy recovery from plasma gasification waste heat (90–150°C range, R245fa working fluid) 2. Heat capture from torch cooling — recovers up to 35% of torch power input 3. Processing chlorinated plastics — rapid spray cooling with filtration prevents dioxin/furan formation when processing PVC 4. IMO maritime compliance — surface temperatures ≤60°C, designed for marine application from the start 5. Modular heat exchanger bypass — maintains system reliability if ORC fails

Total Patent Portfolio

PyroGenesis holds 54+ patents (issued and pending) across all technology lines. PRRS-specific patents are a subset, but the torch technology (APT, APT-HP) and gas cleaning technology patents also apply.

10. Financial Considerations

What PRRS Costs

Item	Cost	Basis
Hurlburt Field (10.5 TPD, turnkey)	$7.4M	Actual cost (2010)
European PRRS (large scale, Phase 1 design)	~$2M	2024 contract
European PRRS (large scale, Phase 2 construction)	$120–160M	2024 estimate
Per-TPD cost (Hurlburt)	~$700K/TPD	$7.4M ÷ 10.5 TPD
Per-TPD cost (European, est.)	$1.2–1.6M/TPD	At 100 TPD

What The Claw Would Need

Phase	Scale	Estimated PRRS Cost	Notes
Phase 1	5–10 TPD	$5–10M	Small module, marinized. Plus design/engineering $2–5M.
Phase 2	50 TPD	$60–80M	Full module
Phase 3	100+ TPD	$120–160M	Based on European estimate

These are equipment costs only. Ship conversion, collection systems, crew, and operations are additional.

PyroGenesis as a Partner

PyroGenesis would be highly motivated to partner on The Claw:

$3M cash, $9.2M working capital deficiency — they need contracts
European PRRS contract stalled — The Claw could be their flagship project
"PyroGenesis cleans up the Pacific Garbage Patch" = priceless publicity
$54.4M backlog provides some stability, but new large contracts are essential

Risk: PyroGenesis is fragile. Mitigation: license the technology, stockpile critical spares, hire key engineers if possible, design with standard components where feasible.

11. Honest Risk Assessment

What Is Proven

Claim	Evidence	Confidence
Plasma torches work at sea	PAWDS on 4 USN carriers, at sea since Oct 2022	HIGH
PRRS can process waste to syngas	Hurlburt Field, 8.5 TPD, ~2 years operation	MEDIUM
Syngas can generate electricity	420 kW ICE at Hurlburt Field	MEDIUM
Graphite arc furnace works at industrial scale	Electric arc steelmaking (similar principle)	HIGH
No-refractory design avoids scaling failures	PAWDS has no refractory; EAFs have no refractory	HIGH
System handles unsorted waste	Hurlburt: MSW + biomedical + hazardous	MEDIUM
Dioxin/furan emissions controlled	Published test data (10x below standards)	MEDIUM

What Is Unproven

Question	Status	Risk Level
Net energy balance (energy out > energy in)?	Never published. 420 kW gross, parasitic loads unknown.	HIGH
Works with ocean plastic feedstock?	Never tested. Different composition than MSW.	HIGH
Molten slag stable under ship motion?	Never tested at sea.	HIGH
Long-term reliability?	Only ~2 years at Hurlburt before closure.	MEDIUM
Why was Hurlburt closed?	No public explanation.	MEDIUM
Can scale to 50–100 TPD?	Design says yes; never built at that scale.	MEDIUM
Electrode consumption rate?	Not published for PRRS specifically.	LOW
Methanol production viable?	Planned for European contract; never demonstrated.	MEDIUM

The TRL Assessment

Technology Readiness Level: TRL 6–7

TRL 6 = System demonstrated in relevant environment
TRL 7 = System prototype demonstrated in operational environment

Hurlburt Field demonstrated PRRS at TRL 7 for land-based MSW processing. But for The Claw's use case (marine, ocean plastic, self-sustaining energy), the TRL drops to TRL 4–5 — component validation in laboratory/relevant environment.

This is exactly what Phase 1 is designed to address. Phase 1 takes PRRS from TRL 4–5 to TRL 7 for The Claw's specific application.

12. What Phase 1 Must Validate

Based on the unknowns identified above, Phase 1 of The Claw must answer these questions:

#	Question	How to Test
1	Does PRRS produce net energy from ocean plastic?	Process actual GPGP feedstock, measure all inputs and outputs
2	What syngas composition does ocean plastic produce?	Gas chromatography on syngas from plastic feedstock
3	Can the slag pool operate under ship motion?	Sea trials with instrumented reactor
4	What is the electrode consumption rate with plastic?	Track electrode wear during extended operation
5	Can wet, salty plastic be pre-processed adequately?	Rinse/dry test with actual GPGP samples
6	What are the actual emissions from ocean plastic processing?	Continuous emissions monitoring during sea trials
7	Can the system achieve 90%+ uptime?	Extended operation tracking
8	Does PVC content create corrosion issues?	Monitor HCl in syngas, inspect gas cleaning system

If Phase 1 answers these positively, PRRS is validated for The Claw. If not, we know before spending $200M.
