Abstract

Abstract : The micro‐fined collagenous buffing dust is one of the most airborne pollutants, which contains chromium, tanning agents, synthetic oil, and dyestuffs. Discarding without proper management could cause environmental pollution and ultimately affect human health. In this study, an approach was made to fabricate composite sheet from the buffing dust incorporating various chemicals. The fabrication process was optimized investigating various parameters. The fabricated composite sheet was finished and inspected for physical properties. Composite finished surface was smooth, light in weight, flexible, and elastic in nature. The tensile strength and elongation at break of the finished composite were 6.03 MPa and 23.3%, respectively. The scanning electron microscope analysis shows that buffing dust was uniformly dispersed in the binding material matrix without structural deterioration. The results indicate that the fabricated composite sheet could be used in the footwear and leather products making. © 2018 American Institute of Chemical Engineers Environ Prog, 37: 1722–1726, 2018
