“…( c ) The retting process breaks the chemical bonds that keep hurd and bast fiber together [ 34 , 35 ]. The separated bast fiber, hurd, and green microfibers have different applications [ 15 ]. Bast fiber can be used to fabricate ropes, textiles, cloths [ 16 ], concrete, composites [ 18 ], and reinforced plastics [ 36 , 37 , 38 , 39 ].…”

“…Global warming [ 1 ], climate change [ 2 ], the escalating demand for energy [ 3 ], the depletion of crude oil resources [ 4 ], pollution [ 5 ], deforestation [ 6 ], and growing concerns regarding environmental crises [ 7 ] have drawn the attention of both industry and academia to altering nonrenewable resources with biobased materials with low environmental impact [ 8 , 9 , 10 , 11 , 12 , 13 , 14 ]. Hemp ( Cannabis sativa ) is an annual plant that has applications in the food and beverage industry [ 15 ], cosmetic products [ 15 ], the textile industry [ 16 ], thermal insulators [ 17 , 18 ], garden products [ 19 ], biofuels [ 20 ], bio-oils [ 21 ], biofibers [ 22 ], paper fabrication [ 23 ], the refinement of water and sewage [ 24 ], nutritional supplements [ 25 ], reinforcing composites and plastics [ 26 , 27 ], and phytoremediation [ 15 , 28 ] (i.e., removing heavy metals from contaminated soil by cultivating plants). Hemp is one of the oldest plants cultivated by humans for its oil, seeds, and fiber [ 29 ], dating back 12,000 years in China, probably introduced to Europe during the Iron Age [ 30 ].…”

Hemp is a sustainable, recyclable, and high-yield annual crop that can be used to produce textiles, plastics, composites, concrete, fibers, biofuels, bionutrients, and paper. The integration of microfluidic paper-based analytical devices (µPADs) with hemp paper can improve the environmental friendliness and high-throughputness of µPADs. However, there is a lack of sufficient scientific studies exploring the functionality, pros, and cons of hemp as a substrate for µPADs. Herein, we used a desktop pen plotter and commercial markers to pattern hydrophobic barriers on hemp paper, in a single step, in order to characterize the ability of markers to form water-resistant patterns on hemp. In addition, since a higher resolution results in densely packed, cost-effective devices with a minimized need for costly reagents, we examined the smallest and thinnest water-resistant patterns plottable on hemp-based papers. Furthermore, the wicking speed and distance of fluids with different viscosities on Whatman No. 1 and hemp papers were compared. Additionally, the wettability of hemp and Whatman grade 1 paper was compared by measuring their contact angles. Besides, the effects of various channel sizes, as well as the number of branches, on the wicking distance of the channeled hemp paper was studied. The governing equations for the wicking distance on channels with laser-cut and hydrophobic side boundaries are presented and were evaluated with our experimental data, elucidating the applicability of the modified Washburn equation for modeling the wicking distance of fluids on hemp paper-based microfluidic devices. Finally, we validated hemp paper as a substrate for the detection and analysis of the potassium concentration in artificial urine.

The transesterification of ethyl ferulate (EF) and unrefined, virgin, cold pressed hemp seed oil (HOV) and refined, bleached, deodorized cold pressed hemp seed oil (HOR) using a commercial lipase, Novozym 435 (Candida antarctica B lipase immobilized on an acrylic resin), was examined in 150‐mL, shaken, batch reactions at 60°C for 2 weeks. The reactions produced feruloylated hemp seed oils, FHOV and FHOR, respectively, and the reactions were monitored to determine the difference between virgin and refined hemp seed oil on the transesterifications. The FHOV and FHOR reactions both reached EF conversion equilibrium of 58% after ca. 168 h. Ultraviolet (UV) absorbing and antioxidant capacity of the FHOV and FHOR were determined. Both FHOV and FHOR (50 μM in ethanol) were excellent UVA II absorbers, λmax 322 nm, and exhibited absorption into the UVB. The DDPH* radical (200 μM) scavenging of the FHOV and FHOR (0.25–2.5 mM) were both shown to be rapid antioxidants (50% DDPH* radical scavenged in <5 min) at 1.0 and 2.5 mM suggesting that inherent components contained in the HOV did not adversely affect enzyme activity relative to transesterification using HOR. Overall, using less expensive, unrefined, virgin hemp seed oil versus more expensive, refined hemp seed oil did not appreciably affect the enzyme kinetics of the transesterification reactions nor the UV absorbing and antioxidant efficacy of the resultant feruloylated hemp seed oils, making FHOV a less expensively produced feruloylated hemp seed oil for cosmetic and personal care applications.

In this paper, an environmentally friendly fabrication process was reported to valorize hemp fibers into biocomposites through a pectin-based crosslinking reaction. In this water-based chemical approach, the hemp fibers were crosslinked via a transesterification process between pectin and lignin present in hemp fibers to produce hemp fiber composites in a one-step process. Our green process was advantageous over conventional processes that rely on the use of petroleum-based organic solvents and high reaction temperatures because water was used as the reaction solvent with a mild reaction temperature (70 C). Additionally, to further optimize this biocomposite fabrication process, one-factor analysis of variance study was carried out for investigating the main and interaction effects of the mass ratios of pectin to hemp fiber (1:5, 2:5, 3:5, 4:5, and 5:5) on the compressive strength and bulk density of the hemp fiber composite materials. In addition, the fabrication process was explored at different pH values to probe its versatility. The compressive strength of the assynthesized hemp fiber composite materials was observed to be dependent on the pH of the reaction conditions, indirectly confirming the formation of ester bonds between pectin and the lignin of hemp fibers via transesterification.
