Facilities
SCWG is not just a technology in development, it is an operational reality. Our current facilities allow us to validate, scale up, and demonstrate the performance of the process with multiple types of organic matter, under real-world conditions and with full control over efficiency.
Testing Platform
The Testing Platform turns a sample into a solution.
It is the real-world laboratory where every SCWG project begins.
The SCWG Testing Platform is the starting point for adapting the process to each type of organic material. It enables full biomass characterization, evaluation of its behavior under real operating conditions, and adjustment of system parameters before moving on to validation at the DEMO plant.
This flexible and technical environment is ideal for conducting specific trials with samples provided by clients, research centers, or R&D projects.
Evaluation of the Physicochemical Behavior of Each Biomass:
Pumpability
Salt Formation
Risk of Obstruction (Fouling)
Density and Viscosity
Modular Pre-Treatment to Adapt Each Sample Before Testing
Filtration
Homogenization
Blending with Other Streams
Testing Objectives
Determine the technical feasibility of each organic stream
Obtain process data for customized system design
Minimize risks before scaling up to DEMO or industrial plant
Tailor the technology to the specific type of available feedstock
DEMO Plant
The SCWG DEMO plant represents the key step between feasibility testing and final industrial design. It is a real, operational, and automated facility capable of continuously processing up to 100 kg/h of wet biomass.
Its objective is to demonstrate that the SCWG process works under real conditions—with extended operation times, advanced parameter control, and stable production of renewable gases.
What do we validate at this stage?
Pre-industrial scale feasibility of your organic feedstock
Process stability under real operating conditions
Reaction times, automation, and quality control
Composition and energy yield of the generated gas
Technical and economic feasibility of scale-up
Direct Scalability
The DEMO plant is not an isolated model. It is a scaled-down replica of the final industrial solution.
Same reactors, same control system design
Modular architecture → expandable without redesign
Foundation for industrial designs from 500 kg/h to 3,000 kg/h
Results obtained here directly inform the final design—no assumptions required
