Zusammenfassung:	The present invention is to provide a method for efficiently manufacturing plant-derived glycolic acid from sorghum useful as a C4 plant, and a method for manufacturing polyglycolic acid, a biodegradable plastic, from said plant-derived glycolic acid. The method for manufacturing glycolic acid comprises: a first process for saccharifying sorghum juice with an enzyme to obtain a sugar solution; a second process for fermenting the sugar solution with alcohol to obtain a fermentation solution comprising ethanol; a third process for fermenting the fermentation solution with acetic acid to obtain acetic acid; and a fourth process for introducing a hydroxy group to the α-carbon of the acetic acid to obtain glycolic acid. (과제) C4 식물로서 유용한 수수로부터 효율적으로 식물 유래의 글리콜산을 제조하는 방법 및 당해 식물 유래의 글리콜산으로부터 생분해성 플라스틱인 폴리글리콜산을 제조하는 방법을 제공한다. (해결 수단) 수수의 착즙에 효소를 작용시켜, 착즙을 당화하여 당용액을 얻는 제1공정과, 당용액을 알코올 발효시켜 에탄올을 포함하는 발효액을 얻는 제2공정과, 발효액을 아세트산 발효시켜 아세트산을 얻는 제3공정과, 아세트산의 α탄소에 하이드록시기를 도입하여 글리콜산을 얻는 제4공정을 포함하는 글리콜산의 제조 방법.
