“…A previous study reported that panel added sludge increased the tensile force by 0.61 N/mm 2 compared without sludge 0.59 N/mm 2 . This was related to the panel's density value, which was better with the addition of sludge (0.9713 g/cm 3 ) than without sludge (1.093 g/cm 3 ). The thickness of the panel also decreased by 66% after the addition of sludge into the wall panel [23].…”

“…Acoustic comfort has been revealed by physicians due to having several problems for human beings such as hearing loss, cardiovascular diseases, and sleep order, and has become an increasingly important concern for both civil engineering and urban design [1,2]. Hence, it is needed to produce sound-absorbing material which is applied in several applications in building, automobile, aerospace industries, and industrial noise instruments [3].…”

“…A good sound absorber material has been successfully produced by layered composite materials based on lignocellulosic waste with low price and minimum impact on the environment, with a medium sound absorption coefficient (α) = 1 [14]. Raw groundnut shell was reported as a sound-absorbing material and it can be used as a promising precursor of sound absorption with a sound-absorbing coefficient at medium and lower frequency [3]. Khalil 2014 studied the physical and mechanical properties of gypsum plaster composites with the addition of waste additives, e.g.…”

The search for green composite for sound-absorbing material has increased a significant interest. In this study, polystyrene (PS) composite foam filled with primary sludge and boiler ash from pulp mill was produced. The product was characterized using analytical techniques such as FTIR, XRD, SEM, TGA, and DSC, while the mechanical properties and sound-absorbing coefficient were analyzed regarding ASTM D 2240 and ASTM E-1050-98, respectively. The results showed that the sludge has 1β crystalline polymorph cellulose from the pulp. The chemical reaction can be seen by the chemical bond formed during the mixing process. The peak expansion occurred at 1600.44 cm-1 indicating the presence of a C=C functional group of maleic anhydride with polymer and filler. SEM images showed that the filler was distributed and dispersed into the polymer matrix and no agglomeration was produced. The sound-absorbing composites had complied ISO 11654:1997 regarding the sound absorption coefficient rating level on materials for rooms with sound absorption classes D and C with the value of α 0.328-0.793.

“…GNS may also be used to make biofuels (Duc et al, 2019). According to Malawade et al, (2021), GNS bio-residues are utilised to generate biofuel, as adsorbents and in other uses. They are also an excellent biosorbent for the adsorption of heavy metals from industrial effluents (Duc et al, 2019).…”

Groundnut Shells as a Potential Feed Supplement for Ruminants on Pastures: A Review

Communal grazing does not offer adequate forage for ruminants throughout the year. This problem is exacerbated during the dry season when grazing is scarce and of poor nutritional quality. Mineral shortages are common in communal grazing environments and yet they are nutritional requirements for optimal development, physiologic functioning and productivity in animals, as well as for cattle growth, reproduction and health. However, the use of groundnut (Arachis hypogea L.) shell (GNS) that are readily available but have no direct nutritional benefit in humans, have not been extensively investigated as a potential source of animal feed. This paper investigates the potential of GNS as feed supplement for ruminants on pasture and its use in other industries. After extracting the seed, the groundnut shell, accounts for roughly 21-29 per cent of the total weight of the nut. Despite the high lignin content of the shell that necessitates adequate processing before use in animal feed, groundnut shell includes 0.50 per cent crude protein, 59.0 per cent crude fiber, 2.50 per cent ash and 4.43 per cent carbs. Sodium (42.00 mg/100 g), potassium (705.11 mg/100 g), magnesium (3.98.00 mg/100 g), calcium (2.28 mg/100 g), iron (6.97 mg/100 g), zinc (3.20 mg/100 g) and phosphorus (10.55 mg/100 g) are all abundant in groundnut shells. In view of this, GNS, a by-product of industrial processing of groundnuts is a rich source of nutrients and can be used to supplement ruminants on pastures during times when pastures are in short supply and of poor quality. Studies are needed to investigate their use to supplement cattle on pasture grazing during times of feed shortage. However, its use as animal feed supplement is likely to face challenges from other industries such as biofuel production.

“…Growing public concern about noise pollution has led to an increased demand for sound absorption materials as effective noise barriers (Jariwala et al, 2017). These materials play a crucial role in softening the acoustics of enclosed spaces by diminishing sound wave energy and reducing the amplitude of reflected waves.…”

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.
