| Sumario: | Recently, Biorefinery is highly focused as a predominant developer in Forest product industry. Pulping black liquor as a rich residual in biopolymers from plant biomasses, has a great potential in bioenergy and biomaterials. In this study, the effects of surface coating of black liquor from bagasse soda pulping (BLBSP) in raw and filtrated form (as 2.5 g. O.D) with different concentration (30, 37, 44 & repeated 44%) on recycled based paper and its properties were investigated. Totally, the BLBSP filtration improved the paper properties more than the raw type, due to its impurity and coarse materials extraction. Higher concentration and content of the applied coatings enhanced grammage (up to 44%) and reduced water absorption (to 200%) and compressive crush resistance (up to >150%). In this regard, film formation, thickening the paper and also the effective role of lignin could be noted beside the bonding enhancement. Repeatedly application of the BLBSP no significantly improved the almost properties, but also decreased them. |
