With the increasing focus on renewable materials and sustainability issues, the development of non-conventional materials from natural resources and possessing complexing properties is currently an area of extensive research due to their potential applications in biosorption processes for pollutant removal. Among them, the hemp plant (Cannabis sativa), an annual high yielding industrial crop grown for its fibres and seeds, is one of the most promising materials for biosorption of metal ions from diluted waste streams. In this review, an extensive list of hemp-based biosorbent literature has been compiled and discussed. After a brief description of hemp and its properties and applications, the review gives a general overview of liquid-solid biosorption processes for metal sequestration from aqueous solutions onto hemp-based materials.
