Popis: | 103 With a rising environmental conscious, wastes reutilization schemes have become the mainstream of sustainable application of resources. This study investigates the feasibility of paper and paperboard products made by autoclaved treated municipal solid waste-derived fiber (MSWF), rice straw cellulosic ethanol fermentation waste (CEFW) and Tea waste (TW). MSW were steamed under 155oC for 60 minutes. CEFW were mixed with steamed MSW and old newspaper (ONP) with ratios of 100:0, 90:10, 80:20 and 50:50, various size of TW with ratios of 80:20 and 50:50. Feasibility of paper (60 g/m2) and paperboard (200 g/m2) production were investigated by analysing their tensile strengths, bursting strengths and tearing strengths. An environmental friendly from kraft black liquor derived binder (BLDB) was used to improve the physical properties of the paper and paperboard products. The values of these properties enhanced linearly with increasing average fiber lengths, regardless of the type of fiber used in the products. BLDB enhanced the physical properties by 50% for papers and 85% for paperboards, and compared with a commercial urea formaldehyde resin. Thermal pressing, however, did not improve the physical properties of the binder enhanced paper products. With the addition of the adhesive binder, CEFW and MSWF showed reasonable substitution potential for ONP fiber by providing suitable tensile and bursting strength in the paper and paperboard. |
