Development of composites based on residual microalgae biomass cultivated in wastewater

چکیده

• Microalgae ultrasound pre-treatment induces strengthening of biocomposites. 20% wt. polycaprolactone reinforced residual Desmodesmus materials. Proteins thermal degradation reduced deformability in Tetradesmus Ultrasound and protein extraction sp. obliquus biomass induced microalgae/polycaprolactone (PCL) biocomposites with higher viscoelastic mechanical properties as injection mould temperature increased. This was probably associated to the promotion microalgae proteins-PCL interactions. The PCL content required, strengthen biocomposites, depended on system (20 or 10 wt% for (RD) (RT), respectively). Protein observed RT-based systems at temperatures than 100 °C. On contrary, a greater crosslinking certain cell disruption RD-based systems. These environmentally-friendly are an interesting alternative replacing petroleum plastics.

Utilization of Microalgae for Integrated Biomass Production and Phycoremediation of Wastewater

Increasing population and Industrialization are key pollutant contributors in water bodies. These wastes are highly hazardous for humansand ecosystem and require a comprehensive, effective treatment before discharge into water bodies. Over the years, many up gradations have been introduced in traditional water treatment methods which were expensive and ineffective especially for removal of heav...
