“…However, natural fibres are increasingly being researched due to their low cost, low density and availability. Natural fibres present a potential substitute in reinforced composites because of rising ecological consciousness and constituted requirements associated with synthetic fibres like carbon and glass [1, 2, 3].…”

“…Nevertheless, certain shortcomings, like incompatibility between fibres and polymer matrices, the propensity to form aggregates during processing, weak interfacial adhesion and the meagre resistance to moisture, had discouraged the use of these natural fibres as reinforcements in polymers [1, 2, 3]. To address these limitations, various treatment protocols have been suggested in the literature.…”

High density polyethylene (HDPE) composites reinforced with short bamboo fibre (BF) were fabricated by compression moulding technique. BF were extracted from bamboo culm and treated with 0.5 M NaOH. The composites were developed by melt-compounding various weight fractions (2, 4, 6, 8 and 10 wt.%) of the treated BF with HDPE with the aid of single screw laboratory extruder at a temperature of 180–220 °C. The extrudates were thereafter moulded into various test specimens with the aid of carver laboratory press at a temperature of 230 °C and applied pressure of 0.2 kPa for 10 min. Effect of the treated BF on the mechanical properties and water uptake behaviour of the composites were studied. The results revealed that there was enhancement in the mechanical properties from 2 – 4 wt.% of BF while the water absorption rate increased with increase in the fibre weight fraction. The morphology of the composites showed that there was a homogenous dispersion of BF at lower weight fraction, although fibre agglomeration was noticed at higher weight fraction. The results of this study revealed that treated bamboo fibres are suitable for reinforcing HDPE.

“…Palm-kernel-shell-ash-reinforced epoxy composites were produced at room temperature. The granulated palm kernel shell ash was mixed with the epoxide-hardener mixture and poured into the molds, as recommended by 9,10 . The molds used for the fabrication were for tensile and flexural (flexural) specifications.…”

This work developed mathematical models for predicting the influence of degradation on the mechanical properties of palm kernel shell ash (PKSA) reinforced epoxy composites. The composites after production were divided into three parts, one part was used as the control samples while the other two parts were buried in soil and water, respectively for 90 d after which experimental tests were carried out based on the ASTM standards. The experimental data from the tensile and flexural properties were analyzed and modeled using a multiple regression analysis to generate higher-order polynomial equations solved to obtain the predicted values. Comparison and validation of the models was carried out through the use of data analysis (T-test and Perron-Frobenious theorem). The result gotten revealed that the tensile properties could be accurately predicted by the developed models at reinforcement of (£8 w/% and ³16 w/% for normal), (£8 w/% for soil) and (£8 w/% for water) while flexural strength was accurately predicted at reinforcement of (£6 w/% and ³18 w/% for normal), (£6 w/% and ³14 w/% for soil) and (³ 1 w/% for water).

The management of agricultural waste has become very important because the inappropriate disposal yields negative effects on the environment. The resource recovery from agricultural waste which converts waste into available resources can reduce the waste and new resource consumption. This review summarizes the 2018 researches of over three hundred scholar papers from several aspects: agricultural waste, and, waste chemical characterization, agricultural waste material, adsorption, waste energy, composting, waste biogas, agricultural waste management, and others.
