Production of Hydrogen-Rich Syngas via Supercritical Water Gasification of Wet Waste

Our paper “Production of Hydrogen-Rich Syngas via Supercritical Water Gasification of Wet Waste” has been published in the inaugural edition of the journal QualEnergia Science.

The study is the result of a strategic collaboration with Calabra Maceri & Servizi and the University of Calabria, and addresses one of the most pressing challenges in sustainable waste management: the energy recovery from high-moisture waste materials such as digestates, leachates, and sewage sludge.

Through the design and development of a pilot-scale supercritical water gasification (SCWG) plant, the project explored the potential of this advanced technology for the production of hydrogen-rich syngas, employing a combined approach of real-scale experimentation and numerical simulations.

The analysis considered various operating parameters — including temperature, pressure, and waste composition — with the goal of optimizing process conditions and maximizing hydrogen yield.

In addition to technical performance, the study also assessed industrial scalability, energy and environmental impacts, and the potential integration of SCWG into existing waste management and energy production systems.

The results confirm SCWG as a promising and sustainable technology, capable of significantly contributing to decarbonization, reducing fossil fuel dependence, and valorizing challenging waste streams, thus opening new opportunities for clean and circular energy.
