dc.description.abstract Chrome shaving waste is one of the highly generated solid wastes. There is no proper utilization of these huge amounts of waste. Preparation of leather board from chrome shaving wastes is economical and helps in reducing environmental pollution. Incorporating plant fibers into leather board preparation enhances its mechanical properties. Fiberized chrome shaving waste mixed with the plant fibers in various proportions (10, 20 and 30%) were used to prepare composite leather board. Plant fibers of sugarcane bagasse fiber and jute fiber were used for the study. Three different types of binders’; natural rubber latex, Fevicol synthetic resin and animal glue in the proportion of 15 and 25% were used for the study and fat liquor were used for preparation of flexible leather board. The prepared leather board were characterized physic chemically using Fourier transform infrared spectroscopy, scanning electron microscopy, Tensile strength, Tear strength, Percentage elongation at break, water adsorption and desorption, chromium trivalent and leachable chromium. Results show that plant fibers improve the physic-chemical property of leather board. Among the composite leather boards, composite board with 30% jute fiber and 20% sugarcane bagasse fiber and 15% fevicol synthetic resin shows better physic chemical property. The leach ability of chrome also decreases when plant fiber is mixed. The composite leather board with 20% sugarcane bagasse fiber has the lowest leachable chromium (0.006%) compared to other composite leather board (0.01%) and control board (0.02%). The thermal stability also doesn’t show sudden degradation. The composite leather boards can be used as raw material for the preparation of leather goods (as a supporting material), mouse pads, false roofing, foot wear (insole), wall partitioning and interior decorations. The study also envisions the production of cost-effective composites, by conversion of wastes into wealth and thereby simultaneously decreasing the environmental pollution. en_US
