The aim of this study is to develop eco-biocomposites using waste leather buff (WLB) as filler in Polylactic acid (PLA) matrix to reduce the environmental issues and provide sustainable solution. WLB/PLA composites were prepared by twins-screw micro extruder varying the WLB content from 2% to 30 wt%. These composite were extensively characterise by several techniques. Tensile properties of the composites showed addition of WLB resulted in improvement of tensile property of composite and reduction in percentage crystallinity of PLA matrix observed with increase in WLB content. The effect of WLB on properties of interfacial adhesion and dispersion in WLB/PLA composites were studied by SEM. Wettability of composites was tested by contact angle and water absorption studies. WLB/PLA composite showed increase in water absorption with WLB loading. These WLB/PLA composite could be used to develop low cost eco-friendly product material.1 aAmbone, Tushar1 aJoseph, Seena1 aDeenadayalan, E.1 aMishra, Satyendra1 aJaisankar, S.1 aSaravanan, P.  uhttps://library.ncl.res.in/content/polylactic-acid-pla-biocomposites-filled-waste-leather-buff-wlb01653nas a2200193   4500008004100000245009100041210006900132260000800201300001400209490000700223520097900230100001801209700002301227700002601250700002201276700001801298700002101316856012201337       2017                        eng d00a Processing and characterization of waste leather based polycaprolactone biocomposites0 aProcessing and characterization of waste leather based polycapro  cDEC  a2889-28970 v383 aWaste leather buff (WLB) filled polycaprolactone (PCL) composites were prepared by twin-screw extrusion varying the WLB content from 2% to 40%. These composites were extensively characterized by several techniques in order to establish micro and macroscopic properties. Addition of WLB resulted in improvement of tensile modulus of neat PCL and reduction in percentage crystallinity of PCL matrix was observed with increase in WLB content. Interfacial adhesion and dispersion of WLB on PCL matrix was investigated using Scanning Electron Microscope. Percentage of water uptake increased with increase in concentration of WLB in the composite. These biodegradable composites could be used to develop low cost materials suitable for applications in footwear industry, for making bags, suitcases, etc., eliminating the environmental issues arising from WLB generated from tanneries in leather industry.
