Beschreibung
Zusammenfassung:	Buluş, polilaktik asidin superkritik karbondioksit ile tek basamakta geri dönüşüm yöntemi ile ilgilidir. A recycling method of polylactic acid in a single step by using supercritical or dense gas carbon dioxide is provided. The recycling method includes the steps of adjusting a temperature of a reactor to at least 120° C., and adjusting a pressure to values above or below a critical pressure of carbon dioxide, wherein the critical pressure is 73.8 bar.
