SCFG PLATFORM SUMMARY
Supercritical Fluid Gasification

Contents

1. The problem it solves

The global waste and sludge treatment industry is facing a triple crisis:

• Rising disposal fees (EU > €160/t) and CO₂ taxes.
• PFAS and “forever chemicals” — regulatory pressure, legal risks and bans on the use of digestates.
• Energy instability and high energy costs, especially for municipal and industrial systems.

Traditional methods (incineration, anaerobic digestion, pyrolysis):

• They are slow (weeks instead of seconds),
• Dependent on external energy,
• They generate emissions and secondary toxic streams,
• They do not destroy PFAS molecularly (but concentrate or move them).

SCFG positions waste not as an expense, but as an energy asset.

2. Technological principle

SCFG (Supercritical Fluid Gasification) is a non-oxidative, autothermal process that uses water in a supercritical state:

• 374 °C
• 221 bars

Under these conditions, water becomes a supercritical liquid — an ideal waste and reaction medium that allows:

• Complete molecular deconstruction of organic waste
• Degradation of the largest C–F bonds (PFAS)
• Reaction speed 1–30 seconds
• Operation without external energy (autothermal)

Key features:

• No oxygen → no oxidative corrosion
• Reactors made of special non-ferromagnetic super-alloys
• Designed service life: ~50 years
• Sealed airtight system (container, 40 ft module)

3. TRL 9 — Operational validation

The technology is declared as TRL 9 — fully commercially operable in real industrial conditions (set up in Switzerland and demonstrations in Croatia).

This means:

• Treatment of real municipal and industrial sludge
• Fully integrated into existing infrastructure
• Industrial scale (up to 150 TPD)
• Proven molecular destruction of PFAS (>99.9%)

This is not a pilot or laboratory technology, but an operational industrial asset.

4. Input — What can be processed?

SCFG handles almost all organic streams, including:

• Sewage sludge
• Biological and agro-waste
• Industrial sludge
• Hospital medical waste
• Plastics & polymers
• MARPOL and biohazard waste
• Waste oils
• Waste with POPs
• PFAS contaminated streams
• Wet waste up to 90% moisture (no drying)

It does not process inert substances such as glass, stone and metal.

5. Output — What do you get?

For a typical input of 1,000 kg/h:

• ~140 kg of energy gas
• ~850 kg of clean technical water
• No CO₂, H₂S or N₂ in the gas phase

Composition of EnerGas

• ~60% CH₄ (methane)
• ~25% H₂ (hydrogen)
• ~15% C₂/C₃ (ethane/propane)

Energy density:

• 36–50 MJ/m³ (significantly higher than conventional biogas)

Additional benefits

• 95% return on distilled water
• Inert mineral residue (sterile ash/sand)
• Potential for the production of SAF precursors
• Generating carbon credits

6. Economic model

Capital expenditures

• €9 – €12 million per module

Revenue (triple stream)

• Waste acceptance fees
• Sale of EnerGas / H₂ / electricity
• Carbon credits

Key economic claims

• Negative OPEX (waste is paid raw material)
• ROI: <10–12 months
• Potential annual gain: €7–12+ million per module
• Elimination of disposal costs
• Elimination of external energy costs

One module can annually:

• Process up to 100,000 tons of organic waste
• Produce >90,000,000 kWh of electricity
• Prevent ~40,000 t CO₂ per year

7. Comparison with alternatives

• Anaerobic digestion: weeks; methane + CO₂; does not destroy PFAS; external energy: yes
• Incineration: quick; dioxin/NOx; partially; external energy: yes; corrosion: high
• Pyrolysis: slow/moderate; limited; external energy: yes; corrosion: high
• SCFG: 1–30 seconds; “zero” broadcast/emissions stream; PFAS 99.9%+; no external energy; corrosion: minimum

8. Strategic implications

1. PFAS crisis

SCFG offers one of the few solutions for molecular destruction of PFAS, instead of filtration or dilution.

2. Hydrogen economy

Production of green H₂:

• No electrolysis
• No additional electricity
• Directly from wet waste

3. SAF Industry

EnerGas of high purity as:

• A precursor to SAF
• Synthesis gas for further processing

4. Decentralized energy

• Modular container systems
• Quick setup (48 hours)
• Autonomous plants
• Ideal for ports, industrial zones, farms, islands, cities

9. Operational and investment advantages

• 50 years of reactor life
• Hermetically sealed system
• Full digital control (PLC/SCADA)
• Possibility of remote control by a single operator
• Compliance with EU IED and EPA standards

Technology redefines:

• Waste Management → Energy Asset Management
• OPEX Center → Profit Center
• Regulatory risk → Carbon income

The SCFG represents:

• Industry-Validated (TRL 9) Technology
• Complete molecular destruction of organic waste and PFAS
• Autothermal process without external energy
• Production of high-calorie EnerGas and green hydrogen
