Hemp hulls, often removed during the dehulling process of hemp seeds, are a rich source of polyphenols, flavonoids, and potent antioxidants. This project investigates upcycling these hulls to extract bioactive compounds that offer significant anti-inflammatory and neuroprotective benefits, transforming an agricultural processing waste into premium health ingredients.
The hemp hulls undergo supercritical fluid extraction (SFE) using CO2 to isolate the sensitive bioactive compounds without the use of harsh, toxic chemical solvents. The resulting extracts are purified, concentrated, and micro-encapsulated to create highly bioavailable ingredients for health capsules and powders.
Producing green hydrogen typically requires energy-intensive water electrolysis. This initiative explores a highly efficient alternative pathway using mixed lignocellulosic biomass (hemp husks and sugarcane bagasse). By leveraging this abundant agricultural waste, the process produces sustainable bio-hydrogen, significantly reducing greenhouse gas emissions and production costs compared to fossil-fuel-derived hydrogen.
The mixed biomass undergoes pre-treatment to break down the lignin barrier. It is then subjected to high-temperature supercritical water gasification (SCWG), directly converting the wet biomass into a hydrogen-rich syngas. The gas is then processed through pressure swing adsorption (PSA) membranes to extract high-purity hydrogen gas.
Hemp hulls are naturally packed with exceptionally high levels of insoluble dietary fiber and essential trace minerals. This project focuses on upcycling the tough outer shell of the hemp seed into natural prebiotic dietary supplements. The high fiber content promotes healthy gut flora, improves digestion, and helps regulate blood sugar levels, providing a sustainable alternative to synthetic fiber additives.
The raw hemp hulls are thoroughly cleaned, steam-sterilized, and subjected to ultra-fine mechanical milling. This process reduces the particle size to improve palatability and gastrointestinal tolerance. The micronized powder is then blended with other natural prebiotics or packaged directly as a functional gut-health supplement.
