Abstract

PurposeThe present work highlights the outstanding properties of Cannabis sativa that can be harnessed for various utilitarian functions and its climate friendly properties.Design/methodology/approachIn this paper, the authors reviewed current research on all possible utilities from household work to manufacturing of various products that are environmentally sustainable. The authors have presented some of their research on this materials and also exploration of hemp as an archaeological material based on the findings from wall paintings of Ellora caves.FindingsThere are references of hemp use in mixing with earthen/lime plaster of western Indian monuments.
