The present study was conducted to determine the recyclability and biodegradability of bamboo fabric-reinforced poly(lactic) acid (BF-PLA) composites for sustainable packaging. BF-PLA composite was recycled through the granulation, extrusion, pelletization and injection processes. Subsequently, mechanical properties (tensile, flexural and impact strength), thermal stability and the morphologica...
Plant-herbivore interactions are hypothesized to drive vole population cycles through the grazing-induced production of phytoliths in leaves. Phytoliths act as mechanical defences because they deter herbivory and lower growth rates in mammals. However, how phytoliths impair herbivore performance is still unknown. Here, we tested whether the amount of phytoliths changes tooth wear patterns. If c...
This study focuses on the strength characterization of artificial fly ash aggregates produced from a pelletization process. Additionally, to improve the stability and strength properties of fly ash aggregates clay binders such as bentonite and metakaolin are added during the production. Physical properties such as specific gravity, bulk density, water absorption, gradation and individual crushi...
Improved methods for broiler chicken (Gallus gallus domesticus) litter utilization are needed to alleviate potential impacts of pollution around broiler production operations. Pelletization may constitute one improved method for handling broiler litter. The objective of this study was to determine the change in nutrient concentration from pelletizing broiler litter, and determine availability o...
The purpose of the study was to screen the effects of formulation factors on the in vitro release profile of diclofenac sodium from matrix pellets compressed into multiple unit pellet system (MUPS) tablets using design of experiment (DOE). Extended release of diclofenac sodium was accomplished using Carbopol 71G as matrix substance. According to Fractional Factorial Design FFD 2(3-1) four formu...
Pelletization of zeolitic materials is required to facilitate their practical industrial and commercial applications. Zeolite-NaA was synthesized from fly ash by the fusion method shaped into spherical granules. Bentonite, kaolinite, a combination bentonite with kaolinite were tested as binders different contents 5 10 wt%. The pellet formation optimized. physicochemical properties binders, zeol...
Many developing countries produce huge amount of agro waste. The disposal this waste is a major problem. residues like wheat and rice husk, sawdust from carpentry shops, groundnut shells, dry leaves plants are available in large quantity. Apart the problems storage, transportation easy handling waste, burning biomass grates poses greater problem widespread air pollution. Biomass pellets well-li...
Bioenergy is one of the potential solutions to satisfy extensive demand for energy and reduce fossil fuel dependency. For biomass be an efficient source bioenergy, it must converted a usable form, which pellets. This study compares three commonly used methods produce pellets in depot presents framework select most effective economic pelleting processes. The comparison performed using data drive...
A lot of residual biomass has energy value and can be used for further applications through suitable treatments, such as pelletization. This treatment improve properties, mainly density, but also lead to problems due their low ash melting temperatures, high content, the formation harmful compounds during combustion. article deals with potential pellets produced from spruce sawdust, bark, pine c...
The optimization of upscaled biochar pelleting is limited by lack knowledge regarding the effects process parameters. A multiparameter model, coupled to a single pellet press unit, was for first time applied production predict behavior. model permits estimate in and cost-effective way how die friction forces, quantified through exiting pressure, are affected key It observed that achieve accepta...
