Abstract (en)
[origin: WO2005011956A2] Process for production or processing of starch-based thermoplastic materials comprising: feeding of starch, water and any other components, as plasticizers, for example polyhydric alcohols, into a first section of a screw extruder; compression and homogenization of the material with formation of a melted mixture in said first section; compression of the mixture in a second section of a screw extruder and extrusion via an appropriately shaped die; process comprising the passage of said material through a pressure control valve located between said first and second section.
