Currently, packaging materials constitute a group of the most commonly used products. Natural polymers are widely tested as potential packaging materials to replace traditional plastics. Sodium alginate is eco-friendly and reveals effective film-forming properties whereas tannic acid has been proposed as a sodium alginate cross-linker. Thin films of sodium alginate/tannic acid were obtained by solvent evaporation. Interactions between the components were determined as well as the maximum tensile strength and color change after contact with different solutions. Improvement in the physicochemical properties of the obtained films was noticed. Moreover, such films showed antioxidant properties. It may be assumed that materials based on a sodium alginate/tannic acid mixture are promising alternatives to traditional packaging materials.

“…The stability of copolymer was observed in order to study the influence of external conditions on the solubility of copolymer. 11 Storage stability: The prepared SG-g-P (AA-co-VAc) emulsion was placed in a container with plug and placed at RT for 5, 10, 20, 30 and 60 days. Then the state of the emulsion was observed.…”

A sesbania gum-g-poly (acrylic acid-co-vinyl acetate) (SG-g-P (AA-co-VAc)) emulsion was prepared by free radical polymerization using environmentalfriendly sesbania gum (SG) as raw material and grafted with acrylic acid and vinyl acetate. It was applied to study the performance of preventing water leakage from the soil. The effects of acrylic acid/vinyl acetate (AA/VAc) monomer ratio, neutralization degree of AA, content of ammonium persulfate and polymerization temperature on the properties of emulsion were investigated. Characterization of the emulsion by FTIR, SEM, TGA, and particle size distribution showed that AA and VAc were successfully grafted onto SG. SG-g-P (AA-co-VAc) had good stability under the optimum synthesis condition. Compared to SG, the thermal stability of the product was improved. The consolidation layer was formed after the product was added to the soil, which might reduce the voids between soil particles and reduce the water penetration rate. This greatly expanded its application in the research of anti-leakage performance.

“…Recently, plenty of innovation applications of dechromed collagen or gelatin have been reported. For instance, Dang et al [134] used gelatin extracted from leather solid waste by alkaline hydrolysis as raw material to synthesize copolymer grafted with acrylamide and acrylic acid by free radical copolymerization, which applied in chemical sand-fixation. The as-prepared copolymer with excellent biodegradability can be combined with sand particles, showing good water retention, anti-wind erosion and anti-water erosion.…”

Leather making is the process of converting raw hides into leather. Amounts of solid waste containing hazardous and high value components are generated during this process. Therefore, the elimination of the potential pollution and resource utilization of leather solid waste are the primary research hotspots. Herein, we comprehensively review the recent advances in the resource utilization of leather solid waste generated from chrome tanning including the utilization of tannery hair waste, untanned solid waste, chrome-containing leather solid waste, tannery sludge and finished leather waste, emphasizing on the general and novel utilization approaches. Finally, the remaining challenges and perspectives were summarized, in order to accelerate the development of resource utilization of leather solid waste.
