BIODEGRADABLE MOULDINGS

A process is described for the production of mouldings based on biological material, wherein potato skins, optionally in the presence of a plasticiser such as glycerol or urea and lecithin and of a water- resistant biodegradable polymer such as polylactic acid, is subjected to a thermomechanical tre...

Beschreibung
Zusammenfassung:	A process is described for the production of mouldings based on biological material, wherein potato skins, optionally in the presence of a plasticiser such as glycerol or urea and lecithin and of a water- resistant biodegradable polymer such as polylactic acid, is subjected to a thermomechanical treatment such as extrusion and then shaped. The mouldings have good mechanical properties and a good biodegradability.
