“…To exemplify the long co-existence with hemp, ancestral archaeological relics date the use of this plant fiber as a fabric to approximately 8000 years before the common era (BCE) as a material in ancient Mesopotamia (present-day Iran and Iraq), and to 4000 years BCE and 3000 years BCE as a material for ropes in China and Kazakhstan, respectively. Impressively, until the beginning of the nineteenth century, it was estimated that around 80% of fabrics, candles, ropes, among other items, were produced from hemp [9,[14][15][16].…”

From the Himalayan mountains to the South American coast, Cannabis, a general term for plants of the genus Cannabis, with thousands of years of contact with humankind, shows its versatility as food tools such as hemp, religious and hedonistic input, and other purposes through the millennia, according to the populations in question. In this paper, a review of the context of the use of Cannabis and its place in world history is presented, from ancient Mesopotamian relics, traditional Chinese and Ayurvedic medicines, to the reasoning behind the isolation and structural elucidation of three phytocannabinoids and the spread of Cannabis throughout the world.

“…Hemp (Cannabis sativa subspecies L.) has been produced for millennia and used in several food and non-food applications [7]. Essential oils and other vital biproducts could be recovered from hemp plants according to the literature [8,9]. Unfortunately, hemp stalks and roots are created as waste and typically end up in landfills.…”

This study aims to enhance value addition to agricultural byproducts to produce composites by the solution casting technique. It is well known that PLA is moisture-sensitive and deforms at high temperatures, which limits its use in some applications. When blending with plant-based fibers, the weak point is the poor filler–matrix interface. For this reason, surface modification was carried out on hemp and flax fibers via acetylation and alkaline treatments. The fibers were milled to obtain two particle sizes of <75 µm and 149–210 µm and were blended with poly (lactic) acid at different loadings (0, 2.5%, 5%, 10%, 20%, and 30%) to form a composite film The films were characterized for their spectroscopy, physical, and mechanical properties. All the film specimens showed CO/OH groups and the π-π interaction in untreated flax fillers showed lignin phenolic rings in the films. It was noticed that the maximum degradation temperature occurred at 362.5 °C. The highest WVPs for untreated, alkali-treated, and acetylation-treated composites were 20 × 10−7 g.m/m2 Pa.s (PLA/hemp30), 7.0 × 10−7 g.m/m2 Pa.s (PLA/hemp30), and 22 × 10−7 g.m/m2 Pa.s (PLA/hemp30), respectively. Increasing the filler content caused an increase in the color difference of the composite film compared with that of the neat PLA. Alkali-treated PLA/flax composites showed significant improvement in their tensile strength, elongation at break, and Young’s modulus at a 2.5 or 5% filler loading. An increase in the filler loadings caused a significant increase in the moisture absorbed, whereas the water contact angle decreased with an increasing filler concentration. Flax- and hemp-induced PLA-based composite films with 5 wt.% loadings showed a more stable compromise in all the examined properties and are expected to provide unique industrial applications with satisfactory performance.
