“…This fiber plant belongs to “poacceae” family of plant kingdom, which is known for its good fiber quality 22 . The Eulaliopsis binata (EB) fiber plant is generally grown on waste lands and also contributes to the soil conservation of the inclined and waste lands 23 . The fiber quality of this plant could be recognized by its existing applications of the fibers as rope, mats, carpets, sofa sets, wall hangings, and other sophisticated fashionable articles that have proved its worth as a structural material with reasonably good mechanical properties 24 .…”

This study is aimed at the potential use of a new natural fiber in polymer based composites (Eulaliopsis binata fiber) as a reinforcing material whose potential for tribological applications is still an unexposed area of research. The characterization studies of the fiber has been carried out with XRD, EDS, and Scanning electron microscope (SEM). Different weight percentages (10, 20, 30, and 40%) of short fiber were taken as reinforcement with epoxy polymer resin and hardener to study the tensile, flexural, and impact strength as well as the abrasive wear behavior of the developed composites. The experimental results indicate significant improvement in the mechanical and wear properties of epoxy with the incorporation of Eulaliopsis binata (EB) fiber. The composites containing 30 and 20 weight fraction of Eulaliopsis binata fiber exhibit optimum mechanical properties and abrasion resistance, respectively. The fractured and worn surfaces of the composites were studied under SEM to find out the failure mechanisms.

“…Comparatively, switchgrass reinforced biocomposites had strengths of 2.4 and 9.5 MPa. [ 20,21 ] Such differences should be due to the inherent properties of the reinforcements. Sabai grass and switchgrass do not have a stiff and strong culm as seen in GCs and bamboo.…”

“…[ 19,20 ] Furthermore, fibers extracted from sabai grass had inherent antimicrobial activity and were also able to provide good acoustic and thermal insulation when used as reinforcement for PP. [ 21 ] Few efforts have been made to utilize GC as a renewable resource to develop composites. Fiber mats from GC were used as reinforcement for epoxy with zirconia toughened mullite as a filling material.…”

Arundinaria gigantea commonly referred to as giant cane (GC) shows potential to be a sustainable, renewable, and low‐cost source for natural cellulose fibers and biocomposites. GC is considered a weed and is found extensively, particularly along river banks and also as canopy under forest trees. The grass is made up of stems (culms) that resemble bamboo but with smaller diameters. In this study, the possibility of extracting natural cellulose fibers from the culms and also to utilize the culms directly as reinforcement for polypropylene (PP) biocomposites has been explored. Natural cellulose fibers extracted from the culms had cellulose content of about 50%. The fibers had considerably high tensile strength of 543 MPa and elongation of 5.6%. Biocomposites with varying tensile and flexural properties could be obtained depending on the proportion of the reinforcement and matrix and density of the biocomposites. Furthermore, reinforcing PP with GC increased acoustic sorption but decreased thermal conductivity. GC offers potential to develop fibers and biocomposites with desired properties as a substitute to the conventional lignocellulosic fibers obtained from fiber crops.

“…Recently, grasses such as Sabai grass (Eulaliopsis binata), an undervalued abundant grass in Asia [118], Cogon grass (Imperata cylindrica), one of the ten most aggressive weeds in the world [119], and Napier (Pennisetum purpureum schum) grass [120] have been considered as composite fillers with promising results. Novel green biocomposites have been lately developed from coffee silverskin and starch-rich potato washing slurries [121] or tea leaves from tea brewing wastes [122].…”

Biobased composites from agro-industrial wastes and by-products

The greater awareness of non-renewable natural resources preservation needs has led to the development of more ecological high-performance polymeric materials with new functionalities. In this regard, biobased composites are considered interesting options, especially those obtained from agro-industrial wastes and by-products. These are low-cost raw materials derived from renewable sources, which are mostly biodegradable and would otherwise typically be discarded. In this review, recent and innovative academic studies on composites obtained from biopolymers, natural fillers and active agents, as well as green-synthesized nanoparticles are presented. An in-depth discussion of biobased composites structures, properties, manufacture, and life-cycle assessment (LCA) is provided along with a wide up-to-date overview of the most recent works in the field with appropriate references. Potential uses of biobased composites from agri-food residues such as active and intelligent food packaging, agricultural inputs, tissue engineering, among others are described, considering that the specific characteristics of these materials should match the proposed application.
