“…Thus, the recyclability of this type of scrap material has become an important and concerning issue. Whereas thermoplastic FRPs can be easily recycled by remelting and remoulding, recyclability of thermosetting FRPs is a more difficult task due to the cross-linked nature of resin matrix (Pimenta and Pinho, 2011). Hence, presently, most of the thermoset based FRP waste is still being incinerated or landfilled, leading to negative environmental impacts and additional costs to FRP producers and suppliers.…”

“…Another advantage is that the recovered oil can be used either as fuel or be refined to regenerate resin feedstock chemicals. As limitation of this technique, the surface fragilities induced by the thermal stress on the recovered fibres, reducing thus its original strength have been reported (Pimenta and Pinho, 2011). Oxidation in fluidised bed is another thermal process for FRP recycling and it consists in combusting the polymer matrix in a hot and oxygen-rich flow.…”

“…Though, this method involves the use of hazardous solvents and, additionally, it requires the previous granulation of scrap material in order to improve the specific surface, which causes length reduction of recovered fibres. Reduced adhesion to polymer matrix in posterior applications is another common drawback of chemical recycling methods (Pimenta and Pinho, 2011).…”

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.

Ruthenium nanoparticles (RuNPs) supported on graphene nanosheets (GNS) composite (Ru/GNS) was prepared by dry synthesis method and was used as a nanocatalyst for the aerial oxidation of various primary alcohols. The Ru/GNS was highly efficient, selective, stable and heterogeneous in nature. Owing to the high stability of the used catalyst (u-Ru/GNS), it was further applied in a different catalytic system viz photocatalytic degradation, after suitable modifications. We have obtained a novel TiO 2 /u-RuO 2 /GNS catalyst from u-Ru/GNS by sol-gel method. The catalytic activity of TiO 2 /u-RuO 2 /GNS toward the photodegradation of methyl orange (MO) and acridine orange (AO) was found to be an excellent. Overall, the sustainable use of these recyclable materials (Ru/GNS and TiO 2 /u-RuO 2 /GNS) could lead to economic and environmental benefits.
