Robert Zarzycki is a researcher at the Czestochowa University of Technology with expertise in biochar technology, energy systems, and thermal–fluid engineering. His work extensively explores the production, modification, and environmental applications of biochar, particularly for improving soil water retention, crop productivity, and climate change mitigation. He has made significant contributions to understanding the long-term aging, chemical properties, and contaminant behavior of biochars derived from diverse feedstocks. In parallel, his research covers combustion, gasification, and modeling of coal and biomass fuels in advanced furnace and boiler systems. He has also published on greenhouse gas reduction, carbon capture–related processes, and cogeneration systems. With a strong background in numerical modeling and experimental analysis, his research bridges environmental engineering and energy technology.
