A comparative study of greener alternatives for nanocellulose production from sugarcane bagasse

PP/Jute Fiber Composites: Effect of Biological Route of Surface Treatment and Content of Jute on Composites

Jute as a fiber has many applications. It is also used in polymers as reinforcement due to its good tensile properties. However, when it is used in polymer matrices, there is a lack of adhesion between the polymer and jute fiber. Surface treatment of fiber using chemicals has been found to improve the properties. However, the use of chemicals causes environmental pollution, when these chemicals are discharged into the environment. In this paper, an attempt has been made to study the effect of the biological route to surface treat the jute fiber. The effect of surface treatment on the morphology of jute was examined. A comparative study was on the crystalline, thermal, and tensile fracture morphology of the composites to understand the effect of the incorporation of untreated and treated jute fibers in polypropylene (PP).

Wetting-consolidation type dust suppressant based on sugarcane bagasse as an environmental material: Preparation, characterization and dust suppression mechanism

Coal mines generate a lot of dust during production and transportation, which not only damages the health of personnel, but also causes environmental pollution. Based on the problems of low extraction efficiency of cellulose matrix and low economy of existing dust suppressants for biomass materials, this paper uses bagasse extracted cellulose from sugar production waste as a matrix and adds polyvinyl alcohol and polyacrylamide as monomers to prepare a wetting-crusting type highly efficient environmental protection dust suppressant for coal mine production and transportation process. The dust suppression effect of the product was analyzed by the performance tests of dust suppression efficiency, consolidation layer strength and permeability. The dust suppression rate of the product prepared in this paper remained above 90% at the simulated wind speed of 10 m/s, the consolidation layer strength of 42.3 KPa was much higher than that of the pure water solution, and the average permeation rate within 30 min was greater than that of the surfactant solution. It is proved that the dust suppressant prepared in this paper has good dust suppression effect, high consolidated layer strength and good permeability, and the product prepared in this paper using environmentally friendly biomass raw materials has good degradability, and the mechanism of the dust suppressant is illustrated by MS simulation. The biomass dust suppressant can meet the requirements of dust suppression in the process of coal mining and transportation and is non-toxic and environmentally friendly.
