Original Abstract

The sustainable utilization of agricultural byproducts is essential for promoting eco-friendly practices across various industries. Hemp processing generates a range of byproducts that can be valorized to enhance both sustainability and economic value. This study explores the valorization of byproducts generated from hemp (Cannabis sativa L.) processing, focusing on their potential applications in the cosmetic sector. (We examined three of hemp seeds processing byproducts, rich in proteins, sugars, and lipids. Hemp seed meal (HSM) and hemp sludge (HS) from cold-pressing seeds for oil extraction, and residual biomass (BAE) from the ethanol extraction of cannabinoids from inflorescences and leaves offer diverse opportunities for further utilization in cosmetic applications. HSM, rich in proteins, sugars, and residual oil, was subjected to hydrothermal extraction and enzymatic hydrolysis to extract water-soluble proteins for haircare formulations, enhancing their nutritive and conditioning properties. This process yielded hemp protein hydrolysate (HPH), a mixture of polypeptides, oligopeptides, and amino acids known for their numerous biological activities. We incorporated HPH into shampoo and conditioner formulations to improve hair reparation due to its soluble proteins and moisturizing effects. Additionally, all the byproducts, HSM, HS, and BAE, were used for the fermentation of the red yeast Rhodosporidium toruloides. This fermentation yielded a ferment containing bioactive compounds such as coenzyme Q10, lipids, carotenoids, and vitamin E, each substrate resulting in a different composition of bioactive compounds. R. toruloides is a non-conventional, oleaginous yeast with a natural carotenoid pathway that accumulates high lipid content. Its lipid extract has demonstrated the ability to increase filaggrin expression, suppress MMP-1 expression under heat stress in keratinocytes, and exhibit antioxidation activity as confirmed by the DPPH assay, highlighting its potential for cosmetic applications. Moreover, hempseed sludge was repurposed for soap production, utilizing its lipid content to create moisturizing soaps with great foamability and exfoliating effects – broadening the application of this waste material for industrial use. This research highlights the significant potential of hemp processing byproducts as valuable resources for creating high-performance, sustainable cosmetics. Our findings contribute to waste reduction and add economic value to the hemp industry, promoting a more sustainable and circular economy.
