“…These findings can be related to the exceptional tensile strength of coconut coir and bamboo fibers which contributed to the improvement of bending strength of cement boards. Similar findings were also observed in the several studies (Asasutjarit et al, 2005;;Macatangay et al, 2012;;Shaduzzaman et al, 2011) in which the addition of natural fibers to cement boards greatly enhanced their bending or flexural strength.…”

Each year, the amount of agricultural wastes is growing faster than the rate of urbanization in the country. People from different parts of the country and the world are mostly unaware on how to utilize these wastes and recycle them into useful and sustainable materials. One of the approaches in reusing these agricultural wastes is to utilize them as a substitute for wood in the fabrication of panel products. Cement-- bonded boards, for instance, is one of those restoration inventions of the 20th century which can be an alternative to timber products in constructing internal and external walls, partitions, ceilings, roof sheathing, to name a few. This research aimed to contribute to these small but growing empirical literatures and studies on particleboard technology by to utilizing agricultural wastes such as bamboo and coconut coir fibers in the production of cement--bonded particleboards. Using an experimental research design, the researchers produced three experimental samples with three different fiber -- cement ratios. These samples underwent several tests that determined their physical and mechanical properties. Based on the results, it was found out that the sample boards with 3.2% fiber obtained the highest strength of 5.31 MPa, which was higher than the standard strength for particle boards. It also passed the nail head pull through test and obtained an optimum result of 223.88 kg. Furthermore, it also exhibited 1.03% thickness swelling and 8.58% water absorption which was way better compared to commercially available particle boards.

“…The result shows that the samples were categorised as good performance because the TS value obtained was between the ranges of 12% -20% [123]. The standard requirement for TS is not more than 20% [124]. Lower thickness swelling values represent higher consistency between fibres which provides better dimensional stability and generally presents higher internal bonding values.…”

Malaysia, like most other developing countries, is facing an increase in the generation of waste and accompanying problems with the disposal of this waste. A large number of biomass wastes were generated due to increased activity in the agricultural and agro-industrial sectors, which led to producing environmental hazards and waste management issues. On the other situation, the energy consumption to cool the indoor building environment is high due to the building being exposed directly to solar radiation throughout the daytime, which increases the temperature outside and inside the building. Most of the low-medium cost housing schemes were constructed using metal roof covering without providing a roof insulation layer which causes a rising in indoor temperature and creates uncomfortable surroundings. Moreover, existing materials for roof insulation in the market use inorganic synthetic materials that could harm human health. The study aims to investigate the potential use of agricultural wastes for the production of roof board insulation material that can provide economic value added to agricultural waste, reduce the environmental issue and provide eco-friendly, sustainable building material. In this study, these agricultural wastes are combined in different proportions of 50% individual fibres, such as sugarcane bagasse with coconut husk, empty fruit bunch with mesocarp fibre, coconut husk with empty fruit bunch, and sugarcane bagasse with mesocarp fibre. The sample was fabricated using the hot-press machine and went through various physical and mechanical testing, which involved thickness of swelling, modulus of rupture, and thermal conductivity. The finding showed that the mixed fibre of empty fruit bunch and mesocarp fibre achieved all the criteria such as density (427 <500kg/m3); thickness of swelling (19< 20%); modulus of rupture (514<800psi), thermal conductivity (0.0856<0.25 W/m.K) met with the standard requirement in every laboratory test conducted. The outcome of this study suggests that empty fruit bunch and mesocarp fibre are the potential materials for the production of roof board thermal insulation. However, modification of physical and mechanical properties of waste fibre is required to achieve superior performance and is ready to be provided in the market. This study is aligned with the government initiative for the growth of green building materials for sustainable development in the construction industry.

“…This study seeks to add value to agricultural waste of maize plant, increase the economic strength of the maize plant and hope to increase the exploitation of maize plant for composite production instead of allowing them to decay or decompose. Corn waste is more than 50% of the entire maize plant which consists of the stalk, leaf, cob, husk with the husk accounting for 10% of the dry corn waste [14]. Thus, this study presents agricultural wastes (corn stalk) as a reinforcement resource in composite production with a view to create cheaper composite materials that can be viable for a wide variety of products such as paper, textiles, fibre-based materials and wood-based panels (fibreboards and particleboards).…”

In this study, corn stalk/polyester composites were prepared using molding techniques at several percentage filler loadings per weight and the physiomechanical properties were studied. The composite showed moderate improvement in tensile strength 13.582MPa for 3% corn stalk which was the highest. The composite also reported the highest values for impact strength 744.90(J/m2 ) and flexural strength 23.947MPa, respectively for filler loading of 3% corn stalk and 93% polyester and 2% corn stalk and 98% polyester composite samples. The significant strengths recorded can be attributed to the good surface intermingling bonding between the corn stalk fillers and the polyester matrix. The study also revealed that, density of the composites decreased with increase in filler loading and the density dropped from 0.116 g/cm3 to 0.108g/cm3 . The composites recorded increase in water uptake with increasing filler loading. The results showed that the highest water absorption rate was at 5% corn stalk loading which had maximum water absorption of 4.55% by the composite samples. The physiomechanical properties of the composites indicate that it can be useful in applications which require moderate strengths. These composites could be considered as a potential way of utilizing agricultural waste materials and as sustainable resources for manufacturing of structural materials such as particle board, partitioning panels, ceiling boards thereby reducing the amount of agricultural wastes and eliminating the pollution caused by burning of corn stalk waste.
