“…As they prepared it for food, a large amount of biomass residues is generated in the process mainly from the enset steam, (i.e., many bundles of fiber are obtained from the leaf sheath and the steam after being scrapped to produce Bula and Kocho which are starchy food) and stack of inflorescence. According to the report by Berhanu et al, 2021, about 150,000 tons of fiber bundles residue are produced annually from enset in Ethiopia. Thus, this enormous quantity of fibers residue could be used to produce CNC products.…”

“…Thus, this enormous quantity of fibers residue could be used to produce CNC products. Several studies have evaluated responses to enset in growing cattle and horses, and its potential has been proven on the production of different products, namely, pulp and paper, food, and medicinal application [15][16][17]. To date, beyond these studies, no work has been carried out concerning enset fiber-based cellulosic nanomaterial.…”

Currently, many scholars are looking for renewable biomass sources for the isolation of nanomaterials that have a sustainable property and are ecofriendly. Thus, effectively synthesize and characterization enset fiber nanocellulose using acid hydrolysis with sonication is focus of study. Additionally, process optimization for isolation of nanocellulose (CNCs) from raw enset fiber using RSM-CCD and characterizations of obtained CNCs was explored. The quadratic model was selected, and optimized values for CNCs yield (77.69%) that were acquired to be H2SO4: 51.6 wt. %, reaction temperature: 47°C, and time: 66.5 min. Chemical composition analysis, XRD, FTIR, PSA, SEM, and TGA were used for characterizing CNCs. The particle size distribution of CNCs is 66 nm. It has a crystalline index of 80.91% and excellent thermal stability. FTIR and chemical composition result indicated the reduction and removal of lignin and hemicellulose components that are usually available in the raw enset fibers. The SEM analysis reveals the structure and arrangement of the fiber bundles inside the raw material to nanocellulose. This property shows its endowing as a possibly consistent load-bearing material. This study could be given a noteworthy thought for designing and emerging CNC isolation, optimization, and industrial application.

“…It is a close relative of the banana plant (genus Musa) and looks like it, except the false banana plants do not grow as edible fruit. Instead, the pseudostem and corms are used as a food source in Ethiopia, where the plant is grown on over 300 thousand hectares as a staple food [10]. This plant domesticated form is only grown in Ethiopia, where it is a staple food of around 20 million peoples.…”

“…Fibers are solid agricultural residual byproducts with a fibrous natural formed by this process. These fibers are sundried and used to make sacks, bags, ropes, mats, and sieves in the past, but these use a small portion of the material, leaving a large amount of residuals with little commercial value [10]. As a result, the eco-friendly solution to agricultural waste management is the proper valorization of these agricultural remnants for higher added value items, which removes the need for their disposal.…”

The main problems in road construction and maintance work in Ethiopia availability of a large amount of appropriate quality materials in road construction sites, aggregates in different size fractions are not readily obtainable, necessitating their procurement from long distances, thereby causing an exorbitant increase in construction costs. One of the main problems in constructing the asphalt paving mixture is obtaining a sufficient amount of filler material from crushing fine rock material and low percent using ordinary Portland cement (OPC), hydrated lime (HL) and marble dust. To overcome this problem, it is important to come across alternative filler material to address this gap using naturally available material. Currently, renewed attention has been given to the use of ‘waste’ materials instead of conventional aggregates in pavement construction. This research study investigates the potential use of ‘Enset’ fiber ash as a partial replacement of conventional filler material in hot mix asphalt supported by experimental laboratory investigation. In order to achieve this study, purposive sampling techniques were adopted to select the sample size and location. The study evaluated the potential of ‘Enset’ fiber ash as filler for the design of dense-graded hot mix asphalt by referencing traditional filler control mix procedures based on standard specifications, and a crush rock filler was utilized as a conventional filler material as a control for comparison. The Marshal Stability and Rutting Test (RT) was conducted to determine the HMA specimen's performance. Several HMA specimens were prepared using aggregate blend according to ASTM D 1559 with four different percentages of ‘Enset’ fiber ash (EFA) of 15%, 25%, 35% and 45% filler replacement the total filler weight used in the control mix. Specimens were prepared and tests performed according to EN 12697-22 procedure-B for rutting test. All HMA properties were taken at 4% air void and determined their optimum bitumen content (OBC). Almost the same result with the control mix was observed in the study at 15% and 25% of the ‘Enset’ fiber ash (EFA) replacement. However, higher Marshall Stability, a lower void filled with asphalt, better flow, a good void in mineral were observed at 25% ‘Enset’ fiber ash (EFA) replacement. At this rate, the rutting performance is less than that of the control mix but is within the specifications of 2.78mm and 2.9 mm of rutting depth less than 6mm that satisfies the EN 13108 requirement. As a result, Enset fiber ash filler can replace traditional filler material up to 25% of the total filler weight used in this study. It was recommended to use ‘Enset' fiber ash (EFA) as a filler material as a partial replacement in a bituminous paving mixture up to the specificed percentage by weight replacement.
