“…This was observed directly in several regional localities. For example, a dual production scheme of fiber and seed in Turkey (Ceyhan et al, 2022) or a combination of concurrent products of biodiesel, fiber, or seed in Malaysia (Szulczyk & Badeeb, 2022), were seen as profitable. However, hemp fiber production only in the Turkish (Ceyhan et al, 2022) and the Malaysian edapho-climatic scenarios (Wimalasiri et al, 2021(Wimalasiri et al, , 2022 resulted in a monetary loss of −555 US$/ha and −2000 US$/ha to −1800 US$/ha, respectively.…”

A recent renaissance of industrial hemp has been driven by a plethora of ecologically amicable products and their profitability. To identify its environment and economic fate across the value chain (VC), this study conducts a systematic review of 98 studies published in ScienceDirect, Web of Science, and Scopus‐indexed journals. The thematic content of the articles is categorized using three deductively derived classification categories: lifecycle analysis (n = 40), VC analysis (n = 30), and feasibility analysis (n = 28). Bibliometric analysis indicates that the majority (>90%) of the studies were conducted in selected regions of Europe or North America, with further findings around regionally prioritized industrial hemp products, such as hempcrete in Southwest Europe, solid biofuel in North European states, and textile fiber and bio‐composites in East Europe and North America. Lifecycle analysis studies highlight nitrogenous fertilizer use during industrial hemp cultivation as a major ecological hotspot, which is taking a toll on the climate change index. However, hemp‐based products are generally climate‐friendly solutions when contrasted against their fossil fuel counterparts, with hempcrete in particular a highly touted carbon‐negative (−4.28 to −36.08 kg CO2 eq/m2) product. The review also identifies key issues within the hemp VC and presents innovative solutions alongside the recognition of value‐adding opportunities. Furthermore, feasibility analysis indicates unprofitability in using hemp for bioenergy production and there is a relative cost worthiness of hemp bio‐composites and hempcrete at the upstream level. Positive returns are observed under co‐production schemes. In contemplating the literature findings, we discussed and identified gap in existing literature for future exploration, including more studies to provide insights from the Global South, and the production of industrial hemp under a biophysically constrained landscape.

“…The price of hemp fibre also depends on climatic/weather conditions, which have effects on fibre yield and is usually diversified in subsequent years and in countries where the hemp is growing. The report covering the comparison of the economic aspects of hemp and cotton fibre production in the USA in 2018 provides data of the total agricultural cost for the fibre production with regards to fibre yield [ 118 ]. The cost of hemp fibre production in the case of medium yields of fibres was in the range between 1328.92 and 357.25 USD/t, while cotton cost production for medium fibre yields was between 3556.48 and 2845.15 USD/t.…”

Over the last several decades, Cannabis sativa L. has become one of the most fashionable plants. To use the hemp potential for the development of a sustainable textile bio-product sector, it is necessary to learn about the effect of the processes creating hemp’s value chain on fibre properties. This review presents a multi-perspective approach to industrial hemp as a resource delivering textile fibres. This article extensively explores the current development of hemp fibre processes including methods of fibre extraction and processing and comprehensive fibre characteristics to indicate the challenges and opportunities regarding Cannabis sativa L. Presented statistics prove the increasing interest worldwide in hemp raw material and hemp-based bio-products. This article discusses the most relevant findings in terms of the effect of the retting processes on the composition of chemical fibres resulting in specific fibre properties. Methods of fibre extraction include dew retting, water retting, osmotic degumming, enzymatic retting, steam explosion and mechanical decortication to decompose pectin, lignin and hemicellulose to remove them from the stem with varying efficiency. This determines further processes and proves the diversity of ways to produce yarn by employing different spinning systems such as linen spinning, cotton and wool spinning technology with or without the use of the decortication process. The aim of this study is to provide knowledge for better understanding of the textile aspects of hemp fibres and their relationship to applied technological processes.

“…12 Depending on that, their industrial production volume has increased noteworthy over the last decade and, the commercial hemp market size has reached roundly six billion $ in the today world due to its use in numerous fields. 13 Additionally, hemp fibers are topologically unique since they are built from the layers separated by the interlocking walls. 10 In more detail, the hemp stalks include lots of phloems at which there existed the fiber bundles (roundly 11.68-31.96 μm diameters) formed by the lumens with the hollow spherical structures.…”

In this current study, rigid polyurethane foams (RPUFs) composites were prepared using different percentage (3, 6, 9 and 12%) of the hemp fibers via one-shut one-step polymerization method. The influences of the hemp fiber addition on the RPUFs were investigated meticulously by means of Fourier-transform infrared spectroscopy (FTIR), thermo gravimetric analysis (TGA), thermal conductivity measurement and scanning electron microscopy (SEM) techniques by evaluating the alternations in the chemical structures of the component, thermal stability, apparent density, insulation performance and cellular topology of the produced samples. The structural analysis revealed that there existed the strong secondary chemical bonds between the functional groups belonging to the components and, depending on that, the improvement in the thermal stability of the foam samples was recorded accompanied by the formation of the better interfacial adhesion. Furthermore, thermal conductivity values of the hemp fiber-loaded RPUFs were observed to increase regularly with the increasing of the content level of the hemp fibers. This was explained by enhancement in the bulk phase conduction level depending of the apparent density rising, reduction in CO2 concentration inside cells as well as the formation of the distorted cellular structures. The obtained air permeability results displayed that the hemp fibers incorporated successfully with RPUF structure, which provides the occurrence of the novel micro barriers and pathways limiting the passage of the air throughout the matrix. The taken scanning electron microscopy images also indicated that the cellular morphology and dimensional stability of the produced foams affected negatively by the hemp fiber addition. At high contents, the wrinkled, non-uniform and irregular cellular structures were observed with ruptured and collapsed walls and struts.
