SCWG Technology

“SCWG represents a new generation of clean technologies with industrial potential for organic resources. Ready to be implemented and to transform waste into useful energy.”

How Does It Work?

The SCWG process uses water in a supercritical state—a special phase of water at high temperature and pressure—as the reaction medium.
This environment accelerates the breakdown of biomass and converts it into a high-value mix of renewable gases, without the need for prior drying or the generation of solid byproducts.

Process Capabilities

SCWG stands out not only for its technological foundation but also for the breadth and robustness of its operational capabilities. It has been developed to confidently tackle real-world challenges in wet organic waste treatment: variable compositions, high moisture content, unpredictable behavior, or difficult pumping. Far from being limited to ideal lab conditions, this system has proven its effectiveness in real-world environments, adapting precisely to each feedstock type and scaling seamlessly toward industrial solutions. These are the capabilities that make it possible:

  1. Broad Compatibility with Biomass Types
    Capable of processing liquid streams, solid-liquid mixtures, sludges, digestates, agri-food waste, olive mill waste, microalgae, and wet agricultural biomass—without the need for prior drying.

  2. Operational Flexibility
    Operates in both continuous and batch modes, adapting to each client’s energy valorization strategy.

  3. Parameter Adjustment Based on Pre-Characterization
    Each sample is analyzed prior to processing: pumpability, salt formation, density, viscosity, and clogging risks are evaluated to configure the process accordingly.

  4. Modular Pre-Treatment
    Organic streams can be filtered, homogenized, or mixed before testing, ensuring stable operation.

  5. Real-World Validation at Pre-Industrial Scale
    The DEMO plant continuously processes up to 100 kg/h, validating process stability, performance, and gas quality under real conditions.

  6. Direct Scalability Without Redesigns
    From 500 to 3,000 kg/h through modular architecture. What is validated in DEMO is implemented at industrial scale using the same components.

  7. Efficient and Clean Conversion
    Stable production of renewable gases such as hydrogen and methane, with no solid byproducts or pollutant emissions.

  8. Low Environmental and Energy Footprint
    The process uses the inherent moisture of the waste as the reaction medium, minimizing energy consumption and eliminating the need for drying or auxiliary combustion.

Industrial Scalability

The technology has been designed from the outset with a modular architecture that enables easy scaling from pilot to industrial plants.

Scale Levels:

  • DEMO Plant: 100 kg/h (operational)

  • Pre-Industrial: 500 kg/h (in development)

  • Industrial: >2,000 kg/h (planned)

This flexibility allows adaptation to local waste volumes or integration into large-scale industrial facilities.

Technology Roadmap

SCWG has followed a technology maturation process validated under real-world conditions:

  • 2023: Validation in pilot environment (TRL 7)

  • 2024: Scale-up to pre-industrial demonstration environment (TRL 8)

  • 2025–2026: Preparation for full commercial deployment (TRL 9)

Each stage has been designed to reduce risks, shorten implementation timelines, and facilitate adoption by existing industries and infrastructure.
