Effect of Cellulosic Waste Derived Filler on the Biodegradation and Thermal Properties of HDPE and PLA Composites

Résumé

Composites with high density polyethylene (HDPE) and poly(lactic) acid (PLA) matrixhave been tested to analyze the eect of natural fillers (wood flour, recycled wastepaper and a mix ofboth fillers) and temperature on polymer degradation. Composting tests have been performed in bothmesophilic (35°) and thermophilic (58°C) conditions. Degradation development has been evaluatedthrough mass variation, thermogravimetric analysis and dierential scanning calorimetry. HDPE,as expected, did not display any relevant variation, confirming its stability under our compostingconditions. PLA is sensibly influenced by temperature and humidity, with higher reduction of Mwwhen composting is performed at 58°C. Natural fillers seem to influence degradation process ofcomposites, already at 35°C. In fact, degradation of fillers at 35°C allows a mass reduction duringcomposting of composites, while neat PLA do not display any variation.
