Resource addition to leather industry: Adhesive from chrome shaving dust

Abstract

Leather industry produces a prodigious amount of wastewater and solid wastage containing a significant amount of hazardous chromium. Chrome Shaving Dust (CSD) is tanned collagenous micro-fine solid particulate impregnated with chromium synthetic fat and oil, tanning agents and dye chemicals. Contrariwise, the adhesive is a material which is used for bonding two or more materials together. This study will reflect the way of eliminating the CSD as a pollutant in leather industry rather it will show its lucrative function by making adhesive which is used in various footwear industries. In such way, it not only saves the environment but also aids to gain marginal profit. The process includes treating the shaving dust with distilled water, magnesium oxide and trypsin enzyme followed by force filtration, heating, evaporating, copolymerization with acrylic resin, polyvinyl alcohol, compounding with polyvinyl acetate, glycerol, Busan bactericide, and Busan fungicide. After that produced adhesive was applied in various parts of footwear to assess its function. The study not only tells about the ethical manufacturing and waste management process but also emphasizes on resource management. This considerably shows the waste generation process and also shows its alternate application in another field rather than polluting environment deliberately. Decaying ecology may get its balance with all natural species by controlling the wastes as well as its implication in an alternative way.
