Abstract: A process for manufacturing a biodegradable polymer filament product, the process comprising: a) isolating polyhydroxyalkanoate from a bacterial culture; b) optionally bleaching the polyhydroxyalkanoate; c) dispersing the polyhydroxyalkanoate in a surfactant solution to form a dispersion; d) drying the dispersion to obtain dried polyhydroxyalkanoate particles; e) mixing the polyhydroxyalkanoate with a plurality of components including a toughening agent, a plasticizer, a nucleating agent, an antioxidant and an adhesive; f) extruding the mixture as a filament; and g) winding the filament onto a spool.
