“…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 ]. Hurd has applications in the production of paper [ 18 ], fuel [ 20 ], hempcrete [ 40 , 41 ], fiberboard [ 42 , 43 ], insulations [ 17 , 18 ], pet litter [ 19 ], garden products [ 19 ], and food preservation.…”

“…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.

“…Furthermore, the production of textiles requires high resource levels. For instance, cotton, found in most clothing, is the most pesticide-dependent crop in the world, using 25% of the world's insecticides and 11% of pesticides [20]. Furthermore, it takes about three years of one consumer's drinking water (2700 L) to make one cotton t-shirt.…”

Increased demands for sustainable apparel products require research to understand better how to encourage sustainable buying behavior effectively, especially in the understudied areas of cross-cultural research. This study, which includes respondents from the UK, US, and China (total n = 711) who completed an online survey, explores determinants of behavioral intention toward sustainable apparel products (SAP). This paper contributes to examine both consumer characteristics (shopping values, consciousness of sustainability, perceived consumer effectiveness, and environmental knowledge) and marketing perspective (evaluation criteria of SAP) determinants for encouraging sustainable apparel consumption behaviors. Significant country differences also emerged, indicating the positive impact on behavioral intention to sustainable apparel products across three countries. Results of structural equation modeling analysis demonstrated there were differences and similarities in the effect of consumers’ characteristic factors and marketing perspective factors on SAP behavioral intention among three countries. The results validate that differentiated marketing strategies in the sustainable apparel industry are required when targeting global consumers to boost sustainable apparel consumption and successfully help to remedy the crisis facing our planet and further generation.

“…Briefly, these plants grow prolifically with limited resources, and the low impact is due to their ability to thrive in natural environments. The main advantages [ 16 ] consist of the fact that synthetic fertilizers are not needed, the plants require less than a third of the water needed for cotton, and these can be grown in many climates and soil types. These characteristics suggest that the production and processing costs can be lower than those for current components of traditional materials.…”

The use of renewable and natural materials characterized by the low environmental impact is nowadays a key issue for the sustainable development of the construction industry. For this reason, the interest for natural fibers, to be used as reinforcement in composites as an alternative to other fibers, is continuously growing. In this paper, the use of hemp for reinforcing lime mortar used as plaster is considered with a multidisciplinary approach, taking into consideration the structural and thermal performance. Natural fibers have several advantages compared to industrial ones, such as low cost, low environmental impact, biodegradability, renewable nature. Moreover, these can show remarkable mechanical performance in relation to specific weight, and sometimes, as in the case of hemp fibers, these can improve the thermal insulation capacity of the plaster. However, the experimental results on the mechanical features are still lacking, especially to assess their durability, and the variability of thermal parameters with the mechanical characteristics. Therefore, this paper proposes an experimental program, developed at Laboratory of Materials and Structures (LAMAS) of the University of Sannio (Italy), aimed at investigating the main mechanical properties (compression strength, flexural strength) of lime mortar reinforced by hemp fibers and subjected to various environmental exposures and aging processes. The characterization is completed with the measurement for the produced samples of the thermal conductivity by means of the standardized guarded hot plate technique.
