and recycled to extraction system because most of solvent is expensive.
2. 3. Compounding
PHB obtained in the extraction process as shape of powder. This powder is transformed into pellets in an extruder to make final product. At the same time, nucleating agents and plasticizers are added to improve processability or mechanical properties.

Silent and endless. The stars shine like the love of God... cold and remote. Against them drifts a tiny chip of technology.
CLOSER SHOT
It is the NARCISSUS, lifeboat of the ill-fated star-freighter Nostromo. Without interior or running lights it seems devoid of life. The PING of a RANGING RADAR grows louder, closer. A shadow engulfs the Narcissus. Searchlights flash on, playing over the tiny ship
