“…53 Coconut fiber, a by-product of coconut husk which is highly rich in lignin and cellulose, was bounded with castor oil polyurethane adhesive to make particleboard. This study was used to check the feasibility of using coconut fiber, castor oil adhesive, and UF to produce qualitative particleboard, varying densities of 0.8 and 1.0 g/cm 3 . The particle mix was placed in the mold and was later inserted in the hot press at a pressure of about 50 kg/cm 2 and the temperature ranging from 100 to 140 C for 10 minutes and with a board dimension of 40 cm × 40 cm with a thickness of 10 mm.…”

“…2 It has been reported that between 8% and 50% of the entire wood-based material is being utilized yearly for various applications to become wastes. 3 These wood wastes though are recyclable are frequently dumped in landfills and some occasions burnt openly constituting air pollution through open-air burning or burnt in a combustion chamber. Over four decades of research and development on the reusable of these wastes have resulted in the manufacture of ceiling panels, flooring, wall, and office dividers, furniture, cabinets, bulletin boards, and desktops.…”

Impending health challenges in the formulations of particleboards from cellulosic-based waste particles such as wood chips, sawdust, and veneer boards are of great concern. These wastes are majorly bonded together with synthetic resin or binder in the presence of heat and pressure to produce particleboards of various specifications and sizes depending on the end-use. The qualities of the particleboards depend on the modification of the particle geometry, resin levels, board density, and manufacturing processes. The addition of special additives to enhance the qualitative performance of particleboards such as dimensional stability, fire retardancy enhancement, and moisture resistance is included in the manufacturing process. The milestone in the use of wood particles for particleboard manufacture is the large reduction in the environmental hazard that these abundant wastes cause. Furthermore, this review reports recent research efforts in the use of green adhesives to reduce the health threat related to utilizing formaldehyde-based particleboard. The use of adhesives produced from natural sources has contributed toward the reduction in the impending health challenges and the cost of building construction by using such a particleboard.

“…Abdulkareem and Adeniyi (2017) noted that the wood alternatives, such as agricultural residues and non-wood crops, have started to play an essential role in this field (Idris et al, 2011;Ezenwa et al, 2019). Prominent agricultural residues include cereal straw; bagasse sugar cane; cornstalks and cobs; stalks of cotton; seeds of sunflower (Fiorelli et al, 2016); rice husk (Madu et al, 2018;Akinyemi et al, 2020); rice straw (Matías et al, 2019); cassava peels (Villamizar et al, 2012); coir pith (Ahmed et al, 2016); red iron wood (Akinyemi et al, 2019a); sawdust (Akinyemi et al, 2019b;Atuanya et al, 2016); and palm kernel shells (Akinyemi et al, 2016). PB is widely used for flooring, wall bracing, ceiling, furniture, partitioning and cladding purposes (Olorunmaiye and Ohijeagbon, 2015;Chibudike et al, 2011).…”

The aim of this work is to optimize the mixing ratio for production of particleboard (PB) from groundnut shell and rice husk. This research is focused on optimization approach for turning the agricultural waste into quality value-added composite PB for sustainable development. Box-Behnken design was used to optimize the effect of three process variables: groundnut husk (0–100 g); rice husk (0–100 g) and resin (1.5–2.5 g). The best process levels for PB production predicted by the software were validated. The PB samples produced were analysed using scanning electron microscope. The best results were obtained at levels: groundnut husk – 50 g; rice husk –100 g; resin – 3.50 g with rupture modulus of 3.50 N·mm−2 and elasticity modulus of 932.4 N·mm−2, the predicted optimal levels of 65.99 g; 86.34 g and 1.69 g were validated. The validation results gave rupture modulus of 3.49 N·mm−2, and elasticity modulus of 932.10 N·mm−2. It can be concluded that PB produced at the optimized conditions satisfied the American National Standard ANSI/A208.1-999 specification for general purpose particleboards for sustainable development.

“…EDX spectrum analysis of the produced adhesive was carried out to identify the existing elemental compositions for their toxicity and friendliness. This is because most adhesive used in composites and particleboard productions are not friendly as they are carcinogenic [3]. The EDX spectra identified 12 elements in the produced adhesive as presented in Table 2.…”

“…Most adhesives used in composites materials production are synthetic and have medical con-cern due to emissions from its users which makes it not environmentally friendly, and are reported carcinogenic due to the presence of formaldehyde derivatives [3,14,29,10]. In a bid to develop environmentally friendly adhesive devoid of any side effects, additives such as plasticizers from diblend or triblend of diethylene glycol dibenzoate and dipropylene glycol dibenzoate are usually added for stabilization of its properties for ease application [6,5].…”

In this study, the optimized adhesive formulated from polystyrene waste was characterized for Fourier transform infrared (FTIR) spectra, Scanning Electron Microscopy (SEM) / Energy Dispersive X-ray (EDX) spectroscopy, solubility, density and water absorption for identification of existing functional group(s), morphology, elemental compositions, etc. The results revealed that polystyrene, unsaturated hydrocarbon has been degraded to form a new product containing aromatic compounds. SEM morphology showed well mixed blended adhesive with silver-like appearance due to additives and EDX revealed 12 existing elemental compositions with their corresponding percentage atomic weights as follows; carbon 93.14 %, hafnium 1.44 %, vanadium 1.66 %, chromium 1.40 %, bromine 0.47 %, palladium 0.26 %, copper 0.43 %, nickel 0.31 %, cobalt 0.29 %, potassium 0.38 %, iron 0.15 % and manganese 0.08 %. The produced polystyrene adhesive was sparsely soluble in water after 30 minutes; it has a density of 1041 kg/m3 and does not absorb moisture. Because of these results, the adhesive from polystyrene waste could serve as green adhesive, since there are no threats of toxic substance emission from the spectral analysis since most of the elements are used as a supplement in pharmaceuticals and catalyst in process industries.
