Waste derived biochar as an alternative filler in biocomposites - Mechanical, thermal and morphological properties of biochar added biocomposites

This study investigated the potential of using waste derived biochar as an alternative filler to manufacture biodegradable non fossil biocomposites. Two types biochars, i.e. (1) wood and (2) sewage sludge biochars were used fillers in Polylactic acid (PLA) BIOPLAST GS2189 biocomposites with loading rate up 20% (by weight). The laboratory manufactured testing samples these subject following tests: water adsorption, tensile strength, impact differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA) optical SEM microscopy. results showed that addition had effect on all parameters, including mechanical, thermal properties. Biochar added higher absorption rigidity. Sewage a for polymers resulted better properties can be successfully produce agricultural accessories such clips supports growing plants, e.g. tomatoes. After harvesting plants disposed plant residues treated through composting. Thus, preventing from generation plastics agriculture are difficult managed.
