Optimization of the Mixing Ratio for Particleboard Production from Groundnut Shell and Rice Husk

Abstract

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.

Physicomechanical and Thermal Properties of Particle Board Produced Using Waste Ceramic Materials and Corncob

“…Tis could be due to the decreased compaction of the panel during synthesis. Hence, there is more room for water penetration [29]. Te particle size of the MCC and WCT and the resin utilised were responsible for the highest WA percentage obtained in this study.…”

“…Particleboards could be stronger when denser materials are utilised. However, the particleboard produced when sawdust and corncob were used revealed low-density particleboard, making the particleboard produced not benefcial for loadbearing function [29].…”

“…Tis is attributed to fewer pores achieved as WCT increased in the composition. Te more the MCC in the composition, the faster the particleboard becomes saturated with water [29]. Sample R7 performed the best in terms of thickness swelling.…”

“…Trough optimisation of the parameters used in the production of groundnut shell/rice husk-based particleboard where UF served as the binder, it was reported that the particleboard synthesised with the optimum parameters fulflled the ANSI/A208-1999 standard for general-purpose particleboards [28]. Considering the major base agrowaste (corncob), Olawale et al [29] investigated the properties of corncob/sawdust particleboard produced using UF as a binder. It was reported that replacing sawdust with corncob between 25% and 50% gave physical properties that are satisfactory for building interior utilisation.…”

“…Utilizing this method, the desired level is affected by independent variables, and the goal is to optimize the response. The optimal value (y k ) was determined by solving the regression equation (Golpour et al, 2020;Olawale et al, 2020):…”
