  • direct use of natural antioxidant rich agro wastes as thermal Stabilizer for Polymer processing and recycling
    ACS Sustainable Chemistry & Engineering, 2016
    Co-Authors: Krishnan A Iyer, Lanhe Zhang, John M Torkelson
    Abstract:

    Antioxidant-rich agro-wastes such as grape pomace waste (GW), turmeric shavings and waste, coffee grounds, and orange peel waste are used as-received for the first time as thermo-oxidative Stabilizers for Polymer. Relative to neat low density polyethylene (LDPE), a well-dispersed hybrid made by solid-state shear pulverization with 4 wt % GW results in 62 and 44 °C increases in temperatures corresponding to 10 and 20% mass loss in air (T10% and T20%), respectively. Such enhancements are superior to those obtained by adding 1 wt % synthetic antioxidant Irganox I1010 to LDPE by melt mixing. Relative to neat LDPE, hybrids with well-dispersed agro-waste exhibit enhanced Young’s modulus, equal or enhanced tensile strength, and relatively small reduction in elongation at break. Reprocessing or recycling sometimes leads to enhanced antioxidant activity: relative to a hybrid before melt extrusion, 92/8 wt% LDPE/TW exhibits major increases in T10% and T20% after two and six melt extrusion passes, which is consisten...
