Summary:Solid waste from all walks have registered their environmental impact by breathing out large amount of greenhouse gases. In this work, not only a waste to wealth strategy for effective utilization of trimmings (Solid waste) from tanning industry to recover gelatin is depicted, but also to use the extracted bio-polymer to develop a product alternative to non-biodegradable plastics. Ability of gelatin to form films is capitalized in the preparation of a composite film system comprising equal percentage ratios of gelatin (Gel) and poly vinyl alcohol (PVA) through solvent casting method. This Gel/PVA composite film is envisaged for producing sustainable packaging film materials. As the existing packaging film materials sourced from petroleum based products cause degradation and disposal concerns, the proposed value addition on the gelatin extracted from waste can be a greener alternative. Through progressive optimizations Gel/PVA film system was incorporated with percentages of glycerol (Gly) and glutaraldehyde (GA) to have performance similar to the low density polyethylene (LDPE) film taken as control. Mechanical, analytical, thermal sealability and printability tests on the developed composite film Gel/PVA/Gly/GA gave optimum results for packaging applications.
