Bio-based polymer additive, a process for preparing the bio-based polymer additive and a biodegradable polymer composition comprising said bio-based polymer additive
The present invention disclosed a bio-based polymer additive, its preparation process and a biodegradable polymer composition comprising the said bio-based polymer additive for use in manufacturing of biodegradable plastic. The said additive is prepared from the biomass of broken microorganism cell such as microalgae, yeast or other microorganisms. In particular, the bio-based polymer additive is for enhancing rheological properties and/or biodegradability of a polymer. In particular, the additive is for use as a pigment.
