“…A shortage of raw materials in some regions has stimulated a search for new fiber sources for panel production. Potential natural or synthetic fibers, such as kenaf fibers, rice straw, chicken-feather, and glass fibers have been explored for these applications (Joshi et al 2004, Juliana et al 2012, Taghiyari et al 2014a. These materials have differing effects on panel properties and any substitute must be thoroughly explored to ensure that it is compatible with the production process and results in a panel with acceptable material properties.…”

The effects of wollastonite fibers on the physical and mechanical properties of medium-density fiberboards composed of wood fibers with up to 10 % camel-thorn chips were studied. Approximately 30 % of the wollastonite fibers were less than 100 nm while the remainder were less than 1 μm. Wollastonite fibers significantly improved most of the physical and mechanical properties while addition of camel-thorn produced more variable effects on panel properties. Up to 10 % camel-thorn could be added to panels without negative effects. A combination of 10% camel-thorn and 5% wollastonite fibers produced panels with the best properties.

“…Although entrapment is one of the simplest methods used for cells and enzymes immobilization that can be adapted for TiO 2 immobilization also. This method consists in the inclusion of these species within polymeric matrices [18]. Biodegradable polymer materials will reduce the need for synthetic polymer and will results in production at a low cost, thereby producing a positive effect both environmentally and economically.…”

Background: Textile industry has been condemned as one of the world's worst offenders in terms of pollution because 10-15% of all the dyes used in the industry are lost within wastewater during processing. The presence of even very low concentrations of dyes in effluent is highly visible and degradation products of these textile dyes are often carcinogenic. Owing to the complex nature of synthetic dyes, conventional biological treatment methods are ineffective. Hence there exist needs for developing treatment techniques that can lead to the complete destruction of the dye molecules from waste stream. The current study focused to develop a new photocatalytic reactor using immobilized TiO 2 capacity to decolourise and degrade textile industry effluent in an effective way. Methods: TiO 2 nanoparticles synthesized by simple precipitation method at pH 5 was successfully entrapped in biopolymer calcium (Ca)-alginate and used as heterogeneous photocatalyst for the degradation of various textile dyes using UV radiations. Photocatalyst was characterized by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The influence of previous operational parameters on the photodegradation has been studied by setting up a laboratory scale photocatalytic reactor. Results: The scanning electron microscopic images indicate that, the alginate gel acts as a bridge that binds the nanoparticles together. The experimental results showed that the rate of degradation depends on the chemical structure of different dyes as well as adsorption of dyes by TiO 2 which is directly proportional to the surface area and dispersion of the catalyst, the adsorption of light by the dye. The kinetics of COD disappearance was slower than the discoloration of the solution. The supported TiO 2 can be used several times without lose of efficiency Conclusions: The results of this study have shown that the degradation of different textile dyes was successfully carried out in laboratory scale photoreactor containing coated TiO 2 as photo catalyst. Calcium alginate can be used as a green support for immobilizing TiO 2 nanoparticles and can be used for developing a new environment friendly immobilization system for large scale water treatment.

“…The flax shives were characterised by higher aspect ratios with longer, narrower, and needle-like particles compared with the hemp hurd particles, which were medium-sized and more rectangular in form, and the wood residue particles, which were shorter and thicker. Numerous studies conducted over the years on the effect of particle geometry on board properties have found that higher bending strength properties are obtained from longer particles because of the greater surface area it provides in terms of contact between particles (Maloney 1993;Juliana et al 2012). Additionally, shorter and thicker particles usually improve the IB strength because they have the tendency to pack themselves together better during mat formation.…”

Flax shive and hemp hurd residues were characterized, and the feasibility of manufacturing three-layered particleboards was evaluated using 2.5% and 5% polymeric diphenyl methane diisocyanate resin loadings. The flax shive and hemp hurd residues had lower bulk densities and higher aspect ratios compared with the wood residues. Their higher aspect ratios offered greater overlap in bonding, which led to consistently higher bending properties that exceeded the American National Standards Institute (ANSI) requirements for low-density (LD2) particleboard and, in some cases, medium-density (M2) particleboard. Because of their particle geometry, the flax shive and hemp hurd particleboards also showed minimal linear expansion with changes in the moisture content at 20 ± 3 °C and between 50% and 90% relative humidity. The high absorption capacity of the flax shive and hemp hurd residues resulted in higher thickness swell and water absorption properties than the wood residues. The results indicated that low-density flax shive and hemp hurd particleboards (500 to 620 kg/m 3 ) can be manufactured using isocyanate resin quantities as low as 2.5% to produce panels that conform to ANSI specifications with a greater mechanical performance than that of wood residue particleboards.
