“…Improper disposal of sugarcane waste poses environmental and health risks due to its solid, semi-solid, and liquid nature (Ungureanu et al, 2019). Groundnut shells, a byproduct of groundnut processing, represent about 30% of the total weight of the legume, processing, represent about 30% of the total weight of the legume, producing around 11 million tons of waste annually worldwide (Mandala et al, 2023). Despite ongoing development in their utilization, groundnut shells, rich in cellulose, hemicellulose, and lignin, hold promise as a source of cellulosic, hemicellulose, and lignin, hold promise as a source of cellulosic biomass for energy production (Rubino et al, 2019) The research aims to investigate the sound absorption coefficient of agricultural waste fiber materials, namely coconut fiber, groundnut shell, and sugarcane fiber.…”

Agriculture, the world’s largest industry, significantly contributes to the GDP of many developing countries, employing over a billion people and producing 1.3 trillion dollars’ worth of food annually. Despite its economic impact, agriculture generates a substantial 140 billion metric tons of waste globally, necessitating sustainable waste management to reduce CO2 emissions. Natural agricultural waste fibers like coconut fiber, groundnut shell, and sugarcane fiber are explored as eco-friendly alternatives for sound insulation to combat noise pollution. The research investigates their application as sustainable sound-absorbing materials, determining sound absorption coefficients based on the ISO 10534-2 standard. Results indicate coefficients ranging from 0.55 to 0.95 within the 160 Hz to 5000 Hz frequency range. Sugarcane fiber exhibited the most favorable coefficients, reaching 0.95 at 1600 Hz and 0.46 at 800 Hz, followed by coconut fiber with a range of 0.84 at 4000 Hz to 0.57 at 160 Hz. This research highlights the potential of agricultural waste fibers in addressing environmental concerns associated with agricultural waste while providing sustainable solutions for sound absorption.

Biochar, a carbon‐rich biomass material has emerged as promising reinforcement and offers versatile applications and potential benefits in various fields, especially in fused deposition modeling (FDM). This study focuses on the development and characterization of groundnut shell‐derived biocarbon (GNSC) reinforced polylactic acid (PLA) filaments for FDM. The GNSC was synthesized through pyrolysis using a tubular furnace at temperatures 700, 800, and 900°C. Synthesized carbon was characterized using Raman spectroscopy, XRD, and SEM analysis. The results showed that the synthesized carbon particles were graphitic, spherical, and nanosized with an average diameter of 40 nm. The preferred biocarbon material, GNSC800 was selected for its high carbon content (98.25%) observed through EDX analysis. Composite filaments were produced with different GNSC800 loadings of 0.25%, 0.5%, and 0.75% using solvent casting and extrusion techniques. Thermal stability was evaluated using TGA and DSC, which showed improved properties with the addition of biocarbon. The mechanical properties and electrical conductivity were enhanced with the inclusion of biocarbon. The data were also validated using ANOVA and Tukey's test. Filament with the 0.5 wt% loading showed the most favorable thermomechanical properties exhibiting a 39.8% increase in tensile strength and a 17.5% improvement in tensile modulus.
