“…Amongst all the methods that can be employed for the activation and chemical modification of jute fibers, ball milling is a promising green technology that is gaining more interest (M'Hamed 2015; Piras et al 2019;Stolle et al 2011Stolle et al , 2013Stolle 2015;Takacs 2002). This technique is commonly used to grind powders and blend materials (Moosakazemi et al 2017).…”

holding, protection against biochemical stress or addition of strength and structure; and hemicellulose, which coordinates cellulose together with lignin (Boerjan et al. 2003; Hansen and Björkman 1998; Panshin and De Zeeuw 1980). Cellulose, as the main constituent of plant cell walls, provides the structural support. It consists of b-D-glucopyranose sugar units, which contain three hydroxyl groups at the C-2, C-3 and C-6 positions. They can form strong hydrogen bonds, constituting the crystalline and amorphous regions within the fibers, which interact with each other to form cellulose microfibrils. Cellulose is known to exist in different polymorphs depending on the molecular orientation and hydrogen-bonding network in crystalline domains. The four main polymorphs of cellulose are cellulose I, cellulose II, cellulose III and cellulose IV. The most extensively investigated are cellulose I, which is the dominant form in natural wood and plants, and cellulose II that can be obtained from cellulose I either by chemical regeneration or mercerization, due to its relatively low thermal stability. Cellulose I, present in native cellulose, exists as cellulose Ia (triclinic unit cell) and cellulose Ib (monoclinic unit cell), both with cellulose chains adopting parallel configurations. In contrast, the chains of cellulose II are in an antiparallel configuration and exist in a monoclinic unit cell (Gong et al. 2017). Despite cellulose I exhibits much better mechanical properties than cellulose II (O'Sullivan 1997; Yu et al. 2014), the later has a more stable structure, making it preferable for various applications. Cellulose can be submitted to a wide variety of chemical modifications due to the three hydroxyl groups present in its structure. Furthermore, reactivity of cellulose can be enhanced through previous Keywords Cellulose Á Jute fibers Á Ball milling Á Isocyanate

“…Mechano-chemistry syndicates the mechanical and chemical methods in combination. For instance, the chemical conversion of the fiber surface can be appreciated by the mechanical force after ball milling technique [80]. Liimatainen et al [81] extracted dialdehyde cellulose using ball milling of kraft wood pulp using sodium periodate as a good oxidizing agent.…”

“…Ball milling has been extensively used for grinding materials and particle refinement since the 1990s. The main components of the machine consist of various sizes milling balls contained within the milling jar or vessel [62]. The resultant shear forces generated among the balls and between them, as well as the surface of the jar then crack the cellulose fibrils into smaller sizes and diameters.…”

Plant biomass is the most abundant natural resources on earth. However, current strategies for the utilization of agricultural biomass is far from efficient, thus environmental issues related to incompetent management of biomass prevail. Innovative handling of surplus biomass can yield several rewards, which includes renewability and sustainability of the commodity as feedstock for industrial and energy purposes. In fact, an array of different parts of a plant or agro-industrial biomass, for instance, shell, husks, wood, and leaves were successfully converted into advanced carbon materials, for use as absorbent, catalyst enzyme support, electrode, etc. In this review, an extensive literature survey related to areas of renewable sources of biopolymer in both the agricultural and industrial sectors were performed. Information on their industrial value and uses, the fundamentals of their extraction alongside the benefits and major drawbacks of their utilization, are also highlighted. We aim to show that the smart utilization of unwanted agro-industrial biomass encompasses a portion of a bigger scheme that intelligently uses biomass to complement current agricultural advancements that create smart crops and growing them using cleverly designed technology. The best part of this “Waste to Wealth” concept is that every part of the crop is fully utilized. However, a set of clear criteria must be in place to ensure a sustained momentum, so that the green approach of responsible biomass utilization will be fully embraced by nations worldwide.
