Shipboard & At-Sea Processing — Proof It Can Work on Water

The single most important finding in this research: plasma waste processing already operates at sea on US Navy aircraft carriers, and two organizations are already building ships to do exactly what The Claw proposes.


PyroGenesis PAWDS — Plasma on an Aircraft Carrier ★

PAWDS = Plasma Arc Waste Destruction System

This is the strongest existence proof for The Claw's concept. A plasma waste processing system that operates at sea, on a moving warship, in combat conditions.

How It Works

1. Waste fed to shredder (handles mixed waste, no sorting needed) 2. Shredder output goes to mill (converts to powder/lint) 3. Powder fed into plasma-fired eductor and chamber 4. Plasma destroys all organic material at 5,000°C+ 5. Output: inert residue + clean exhaust

Key Design Features

  • No refractory/brick materials — major advantage over traditional incinerators (lighter, less maintenance)
  • Scalable — designed to scale UP for cruise ships and DOWN for frigates/destroyers
  • Proven at sea — operational on active duty warship since October 2022

What This Means for The Claw

1. Plasma at sea is proven. Not theoretical. Not a lab test. Operating on a $13 billion warship. 2. PyroGenesis already makes marine-rated plasma torches. No need to reinvent. 3. The Navy solved the shredding problem — mixed waste, no sorting, one-button operation. 4. PAWDS processes 4.8 TPD on a MOVING warship. A STATIONARY platform is easier. 5. Military-grade reliability — if it works for the US Navy, it works.

PyroGenesis is the torch supplier for The Claw. Period.


SeaChange Ocean Solutions — The Closest Existing Project ★

California-based nonprofit partnered with InEnTec to deploy mobile PEM (Plasma Enhanced Melter) on a ship.

The Plan

1. First vessel processes 2 TPD of plastic at sea 2. Plastic heated to nearly 10,000°C (surface-of-the-sun temperature) 3. Vaporized and broken down into molecular components 4. Outputs: hydrogen-rich syngas (powers the operation) + inert glass (safe to release into ocean) 5. Scale to land-based PEM systems processing 125 TPD

Target Areas

  • Remote island locations lacking waste infrastructure
  • Developing nations
  • Regions near the ten major rivers responsible for 90% of ocean plastic input

Status

  • Partnership with InEnTec established
  • Vessel design underway
  • Pre-operational (as of last available information)

What This Means for The Claw

SeaChange is attempting THE EXACT SAME CONCEPT: plasma gasification of ocean plastic at sea, self-powered by syngas. The difference: SeaChange is a mobile ship that moves to the plastic. The Claw is a stationary station that plastic is brought to.

Potential collaboration/merger opportunity? Or competitor to watch?


Ocean Saviour Vessel — The Big Blue Ocean Cleanup

The Design

  • 70-meter tri-deck cleanup vessel
  • Designed to be self-powering using plasma gasification
  • Manta Collector Array systems at sides and front draw in plastics
  • Onboard conveyor chops and mills plastic
  • Fed into onboard plasma gasification facility
  • Syngas fuels the vessel itself

Technology Source

  • Plasma technology derived from PyroGenesis PAWDS — the same system on the USS Gerald R. Ford
  • PyroGenesis providing the torch technology

Status

  • Design phase
  • Pre-construction

What This Means

Another organization building a self-powered plasma-processing ocean cleanup vessel. The concept is convergent — multiple groups independently arriving at the same solution.


Traditional Shipboard Incineration (Context)

Current State

  • Most commercial ships use MARPOL Annex VI compliant batch-loaded incinerators
  • US Navy legacy: ~30 ships still use sludge incinerators based on 1950s technology
  • IMO MEPC 76(40) sets standards for shipboard incineration
  • Regulation 16 of MARPOL Annex VI

What's Prohibited

Cannot incinerate:
  • Cargo residues under MARPOL Annexes I-III
  • PCBs
  • Garbage containing heavy metals

Limitations

  • Batch processing (not continuous)
  • Requires waste segregation
  • Produces ash requiring disposal
  • Lower temperatures — doesn't destroy all toxins
  • Air emissions (NOx, SOx, particulates)
PAWDS replaces all of this — continuous, no segregation, no ash, no visible emissions, higher destruction efficiency.


Other At-Sea Concepts

Self-Sustaining Ocean Cleanup (Siskowet Enterprises)

  • Battery-powered autonomous drones sweep up plastic, return to a "mother ship"
  • Plastic converted to electricity via high-efficiency waste-to-energy incineration on mother ship
  • Incineration, not plasma — less clean but potentially simpler

PEAT International (Taiwan)

  • Built facility at National Cheng Kung University, Tainan
  • Processes 3-5 metric TPD of incinerator fly ash, medical waste, organic industrial waste
  • Proprietary Plasma Thermal Destruction Recovery method
  • Not marine-deployed but proves small-scale plasma processing

The Convergence Pattern

ProjectApproachPlasma?Self-Powered?At Sea?Status
PAWDS (US Navy)Waste destruction on carrierYESNo (carrier powered)YES ★Operational since 2022
SeaChange + InEnTecMobile ship, PEM processingYESYES (syngas)YESPre-operational
Ocean Saviour70m vessel, collection + processingYES (PyroGenesis)YES (syngas)YESDesign phase
The Claw (proposed)Stationary platform, collection feeds inYESYES (syngas)YESConcept
SiskowetDrones + mother shipNo (incineration)YES (WtE)YESConcept
Multiple independent groups are converging on the same solution: plasma processing of ocean plastic at sea, self-powered by syngas. This is the strongest possible validation of The Claw's concept. We're not alone in thinking this — we're part of a convergent evolution toward the obvious answer.


Implications for The Claw

What's Already Proven

  • Plasma at sea works (PAWDS, 2022)
  • Marine-rated plasma torches exist (PyroGenesis APT-HP)
  • Shredding mixed waste on a ship works (PAWDS)
  • The concept of self-powered ocean plastic processing is independently validated by multiple groups

What Remains Unproven

  • Stationary platform vs. mobile vessel (different engineering challenges)
  • Energy balance with actual ocean plastic feedstock (vs. ship waste)
  • Scale beyond 5 TPD at sea
  • Continuous (not batch) processing of ocean debris specifically
  • Tangled fishing net shredding in marine conditions

Strategic Questions

1. Partner with SeaChange/InEnTec? They have the PEM tech and are already doing this. 2. License PyroGenesis PAWDS? They have the military-proven marine torch. 3. Compete independently? More expensive, slower, but full control. 4. Hybrid? Use InEnTec PEM + PyroGenesis torches + our own platform design.

Recommendation: Reach out to both InEnTec and PyroGenesis. They want this technology deployed. We want to deploy it. The conversation should be natural.
