BIODEGRADABLE THERMOPLASTIC MOULDING AND EXTRUSION COMPOUNDS MADE FROM BIOMASS

摘要

The present invention is directed to a method of making thermoplastic granulates. A comminuted biomass is mixed with a lignin swellant such that the content of substances soluble in diethyl ether is at least 3.0% and ground and processed in a compounding extruder equipped with compaction, heating, cooling venting and grinding zones to form thermoplastic dry blends and granulates.
