“…Therefore, the production of fiberboards without synthetic resin was challenging. Chemical pretreatments, such as alkaline, acid and oxidation agents, have been utilized in the activation of fiber surface (Anglès et al 2001;Geng et al 2006;Schmidt et al 2002;Young et al 1985). Binderless fiberboards made from alkaline-treated black spruce bark possessed a higher IB, modulus of rupture (MOR) and modulus of elasticity (MOE) than those of untreated samples (Geng et al 2006).…”

Binderless fiberboards made from alkaline-treated black spruce bark possessed a higher IB, modulus of rupture (MOR) and modulus of elasticity (MOE) than those of untreated samples (Geng et al 2006). Compositions analysis revealed the occurrence of de-acetylation of wood fibers, as well as degradation of large amounts of lignin and hemicelluloses (Schmidt et al 2002).…”

“…Black spruce is one of the major forest species in this region (Apps and Halliwell, 1999) and regularly harvested for pulp and fiber production (Geng et al, 2006). Due to the geomorphology shaped by glaciers and ice sheets in the Pleistocene and occasional stand-replacing fires, the landscape is a mosaic of relatively well-drained upland forests and poorly drained woodlands in various ages.…”

“…Chemical treatment in general improves the fillermatrix adhesion, interfacial strength and thermal and water barrier properties of MSW. Geng et al [5] developed sodium hydroxide-treated black bruce bark boards. The results indicated that treated bark boards have higher internal bonding strength and higher bending strength compared to untreated bark boards.…”

Municipal solid waste (MSW) generation increased rapidly due to the change in food habits, increasing urbanization and changed lifestyle of people. The aim of the present study was to analyze the possible use of MSW as filler in fiber-reinforced urea formaldehyde composites. The mechanical properties of the composites were investigated as a function of different volume fractions ( V f ) of filler (MSW and banana fiber) and its chemical modification. The MSW was chemically treated using NaClO/H 2 O (1:1) at 60 ° C and was analyzed using density measurement, X-ray diffraction, Fourier transform infrared spectroscopy, and scanning electron microscopy (SEM). The water absorption and thermal behavior of both raw and treated MSW were also studied. The chemical composition of treated MSW showed decreased cellulose and lignin content compared to that of raw MSW. MSW/banana fiber-reinforced urea formaldehyde composites with different filler ratios were prepared. The composites were analyzed by SEM and tensile, flexural and impact strength tests. The tensile, flexural and impact strength increased up to 40% V f of filler and then decreased, which indicates effective stress transfer between fillers and matrix. The chemically treated composites showed higher tensile and flexural strength compared to untreated composites due to the strong interfacial interaction between the resin and the fiber.
