“…At present, Malaysia is the world's third largest exporter of MDF after Germany and France with a total export amounting to RM1.2 billion in 2008. Moreover, numerous studies employing the usage of palm oil EFB have been conducted by researchers (Ahmad et al, 2010(Ahmad et al, , 2012Al-Oqla and Sapuan, 2014;Bateni et al, 2011;Chauhan et al, 2008;Hejazi et al, 2012;Mujah et al, 2013;Park, 2009Park, , 2011 denoting the suitability of such waste to be reused as reinforcing agent towards problematic soils. It can be concluded that EFB is effective in soil reinforcement based on the fact that it increases the soil shear strength parameters around 25%e35% (Ahmad et al, 2010).…”

“…Regarding this subject, over the last 20 years several end-use applications were envisioned and investigated for mechanically recycled thermoset GFRP wastes or recovered glass fibre wastes: i) filler material for artificial wood (Demura et al, 1995), high density polyethylene plastic lumber (George and Dillman, 2000), rubber pavement blocks (Itoh and Kaneko, 2002), dense bitumen macadam (Woodside et al, 2003), and bulk or sheet (BMC/SMC) moulding compounds (DeRosa et al, 2005), ii) reinforcement for wood particleboard (Reynolds et al, 2004) and soils (Ahmad et al, 2012;Mujah et al, 2013); and iii) core material for textile sandwich structures (Adolphs and Branca, 2001). Most of them have not succeeded for one or both of the following rea-sons: a) tendency of the recyclate addition to negatively affect the mechanical properties of final composite; and b) negative cost balance, where mechanical recycling and sorting operational costs outweighed the market value of the virgin product (chop-ped glass fibres and calcium carbonate) (Halliwell, 2006;Palmer et al, 2009).…”

A b s t r a c tIn this study, efforts were made in order to put forward an integrated recycling approach for the ther-moset based glass fibre reinforced polymer (GPRP) rejects derived from the pultrusion manufacturing industry. Both the recycling process and the development of a new cost-effective end-use application for the recyclates were considered. For this purpose, i) among the several available recycling techniques for thermoset based composite materials, the most suitable one for the envisaged application was selected (mechanical recycling); and ii) an experimental work was carried out in order to assess the added-value of the obtained recyclates as aggregates and reinforcement replacements into concrete-polymer com-posite materials. Potential recycling solution was assessed by mechanical behaviour of resultant GFRP waste modified concrete-polymer composites with regard to unmodified materials. In the mix design process of the new GFRP waste based composite material, the recyclate content and size grade, and the effect of the incorporation of an adhesion promoter were considered as material factors and systemat-ically tested between reasonable ranges. The optimization process of the modified formulations was supported by the Fuzzy Boolean Nets methodology, which allowed finding the best balance between material parameters that maximizes both flexural and compressive strengths of final composite.Comparing to related end-use applications of GFRP wastes in cementitious based concrete materials, the proposed solution overcome some of the problems found, namely the possible incompatibilities arisen from alkalis-silica reaction and the decrease in the mechanical properties due to high water-cement ratio required to achieve the desirable workability.Obtained results were very promising towards a global cost-effective waste management solution for GFRP industrial wastes and end-of-life products that will lead to a more sustainable composite materials industry.

The inclusions of geosynthetic materials (fibers, geomembranes and geotextiles) is a new improvement technique that ensures uniformity in the soil during construction. The use of tension resisting discreet inclusions like polypropylene fibers has attracted a significant amount of attention these past years in the improvement of soil performance in a cost-efficient manner. A series of direct shear box tests were conducted on unreinforced and reinforced Chlef sand with different contents of fibers (0, 0.25, 0.5 and0.75%) in order to study the mechanical behavior of sand reinforced with polypropylene fibers. Samples were prepared at three different relative densities 30%, 50% and 80% representing loose, medium dense and dense states,respectively, and performed at normal stresses of 50, 100 and 200 kPa. The experimental results show that the mechanical characteristics are improved with the addition of polypropylene fibers. The inclusion of randomly distributed fibers has a significant effect on the shear strength and dilation of sandy soil. The increase in strength is a function of fiber content, where it has been shown that the mechanical characteristics improve with the increase in fiber content up to 0.75%, this improvement is more significant at a higher normal stress and relative density.
