Green extraction of natural products. Origins, current status, and future challenges

Before the petroleum era, plant biomass powered our world—and dwindling fossil fuels are now pushing us right back to our botanical roots. Can we reinvent how we extract nature's most valuable compounds without destroying the planet?

Green extraction is designed to slash energy consumption and banish petroleum solvents, all while securing safe, high-quality extracts. It meets the pressing environmental and consumer demands of the 21st century, helping both academia and industry boost their ecological and economic innovation.

From plant materials emerge a treasure trove of metabolites—think proteins, fats, oils, dietary fibers, sugars, antioxidants, essential oils, and vibrant colors. These vital ingredients drive the agro-food industry, cosmetics, perfumery, biofuels, and fine chemicals.

Traditionally relying on complex solid-liquid extraction steps like drying and grinding, the field is undergoing a massive review. By exploring definitions, principles, and future challenges, this movement points humanity toward a post-petroleum society powered by the green chemistry of natural products.

Key Points

• Reduce or eliminate energy and petroleum solvents
• Sourced from plant primary and secondary metabolites
• Applications in agro-food, cosmetics, and biofuels
