The objective of this investigation was to introduce a cement-based composite of higher quality. For this purpose new hybrid nanocomposite from bagasse fiber, glass fiber and multi-wall carbon nanotubes (MWCNTs) were manufactured. The physical and mechanical properties of the manufactured composites were measured according to standard methods. The properties of the manufactured hybrid nanocomposites were dramatically better than traditional composites. Also all the reinforced composites with carbon nanotube, glass fiber or bagasse fiber exhibited better properties rather than neat cement. The results indicated that bagasse fiber proved suitable for substitution of glass fiber as a reinforcing agent in the cement composites. The hybrid nanocomposite containing 10 % glass fiber, 10 % bagasse fiber and 1.5 % MWCNTs was selected as the best compound.

There is a considerable amount of waste produced daily from processing old corrugating containers. Dumping this waste product incurs a considerable cost to a paper recycling mill. In this study a sample of waste containing 45% fibrous and 55% non-fibrous solid was collected from an old corrugating containers paper-recycling mill and analyzed in a laboratory. The waste was used to produce wastes-urea formaldehyde composites and wastes-polyethylene composites. Physical and mechanical properties of the resulting manufactured panels were compared with commercially produced medium density fiberboard and particle board. The results presented the possibility of panel production from waste, even without inclusion of any additional material. Additives would obviously enhance the physical and mechanical characteristics of a product to render it more competitive with commercially produced panels. The results also revealed that water absorbability and thickness swelling of panels were much less compared with similar commercially available products. The mechanical characteristics of the manufactured panels were weaker relative to the commercially available ones, probably due to differences in density and thickness. Hence, wastes-urea formaldehyde composites and wastes-polyethylene composites panels can be recommended for application if physical properties are more important than mechanical properties.
