- Abstract
The leather sector is currently under heavy threat to reduce environmental pollution problems associated with the generation of leather waste, especially in terms of public acceptance issues related to environmental welfare requirements. Leather waste must be disposed of in landfills, which has a significant environmental impact. The development of natural polymer/paper mill sludge-based leather replacements for the production of leather goods and footwear products is an alternative solution supported by the recycled leather industry. In this work, a study is carried out to prepare natural polymer leather sheet (NPLS) from leather waste (chrome shavings and buffing dust), paper mill sludge, and natural polymer [natural rubber latex (NRL)] by vacuum-pressure method, for their potential application in leather products industries. The NPLS was characterized by its physicochemical and mechanical properties. Various types of NPLS were produced by comprising different ratios of the NRL. Results portrayed that 300 mL w/v NRL significantly improved the physicochemical and mechanical properties of NPLS. Hence, the research has revealed a revolutionary idea of NPLS developed which is cost-effective, eco-friendly, and energy efficient.
