Production of bioplastic material from algal biomass [PDF]
Chemical Industry and Chemical Engineering Quarterly, 2021 Bioplastic composite material was developed from polylactic acid used as basic polymer and microalgae. Two types of biomaterials were prepared based on the proportion of microalgae and polylactic acid. The mass ratios were set to 5:95 and 10:90.
