Development of Electrospun Films from Wastewater Treatment Plant Sludge

Electrospinning is a versatile method for producing continuous polymer nanofibers, including from wastewater treatment plant sludge (WTPS). In this context, purified WTPS was successfully used to produce electrospun fibers. The main objective of our research new, local, circular, renewable and environmentally friendly packaging material. aim the purify treat make it suitable electrospinning process, thus new material chemically characterizing in first step. One major advantages process that could be carried out with water ethylenediaminetetraacetic acid. optimal viscosity determined 20,000 mPas order sufficient nanofibers. Analyses such as Fourier-Transform Infrared Spectroscopy (FTIR) 1H-NMR (proton nuclear magnetic resonance) were determine substances unpurified WTPS. tensile properties, contact angle, surface properties differential scanning calorimetry final used. analysis confirmed presence small quantity polyhydroxyalkanoates samples. Based on brittle less stretchable compared films available market.
