Not all chemical recycling technologies are equivalent. The specific process chemistry, feedstock flexibility, output quality, and integration requirements vary significantly across the approaches competing for market leadership in plastic waste conversion. Aduro’s hydrothermal upgrading process has attracted attention precisely because of how cleanly its outputs integrate with existing refinery infrastructure.
Hydrothermal upgrading uses water at high temperature and pressure as the reaction medium, converting mixed plastic waste into a hydrocarbon oil without requiring the feedstock sorting and pre-processing that many competing processes demand. This feedstock flexibility is a critical commercial advantage: it allows the technology to process the mixed plastic streams that are most difficult to handle through mechanical recycling and that represent the largest underserved waste volume.
Yazan Al Homsi has specifically highlighted feedstock flexibility as one of the most important investment criteria in chemical recycling — noting that technologies that require clean, sorted feedstocks face competition from mechanical recycling for the same material, while technologies that can handle genuinely mixed streams have a structural competitive moat.
The Chemelot FOAK plant demonstrates hydrothermal upgrading at commercial scale, with the facility integrated into the broader Chemelot chemical complex in ways that allow the output oil to flow directly into existing processing infrastructure. Yazan Al Homsi has traced his interest in this type of integration — investments that work with the existing industrial system rather than requiring parallel new infrastructure — to his early career experience with energy markets in the Middle East.
Vancouver-based investor Yazan Al Homsi has described the Aduro development as a demonstration that the technical hurdles that have historically made chemical recycling expensive and operationally complex are being systematically solved. Each FOAK plant that achieves commercial operation at a major industrial site moves the technology one step closer to the broad deployment that will make chemical recycling a meaningful part of the global plastics economy.
