Polylactic acid (PLA) waa polymer polymerized oo leh lactic acid oo ah alaabta ceeriin ee ugu weyn, taas oo si buuxda loo soo saaray oo dib loo soo saari karo.Habka wax soo saarka ee polylactic acid waa wasakh la'aan, badeecaduna waa la baabi'in karaa si loo gaaro wareegga dabiiciga ah, sidaas darteed waa wax ku habboon polymer cagaaran.Polylactic acid ((PLA)) waa nooc cusub oo walxo biodegradable ah oo loogu talagalayalaab caag ah, daabacaadda 3D.Istaarijka laga soo saaro khayraadka dhirta la cusboonaysiin karo (sida galleyda) ayaa laga sameeyaa lactic acid iyada oo halsano ka dibna loo beddelo polylactic acid by polymer synthesis.

Poly (lactic acid) waxay leedahay biodegradability heer sare ah waxaana gebi ahaanba hoos u dhigi kara 100% noolaha yar yar ee ciidda hal sano gudaheed ka dib marka laga tago, taasoo keenta kaarboon laba ogsaydh iyo biyo oo aan wasakhayn deegaanka.Si dhab ah loo gaaro "laga bilaabo dabeecadda, ka tirsan dabeecadda".Sii daynta kaarboon laba ogsaydhyada adduunka sida lagu sheegay warbixinnada wararka, heerkulka adduunku wuxuu kor u kici doonaa ilaa 60 ℃ sanadka 2030. Caagagga caadiga ah ayaa wali la gubayaa, taasoo keenaysa xaddi badan oo gaas aqalka dhirta lagu koriyo ah in lagu sii daayo hawada, halka polylactic acid ay ku duugan tahay ciidda si ay u xaalufiso. .Kaarboon oksijiinta ka dhalata waxay si toos ah u gasho walxaha organic-ga ah ee ciidda ama ay nuugo dhirta, laguma sii dayn doono hawada, ma keeni doonto Saamaynta Greenhouse.

Poly (lactic acid) waxay ku habboon tahay hababka wax-soo-saarka ee kala duwan sida qaabaynta dharbaaxada iyoqaabaynta irbado.Way fududahay in la farsameeyo oo si ballaaran loo isticmaalo.Waxa loo isticmaali karaa in lagu farsameeyo dhammaan noocyada weelasha cuntada, cuntada baakadaysan, sanduuqyada qadada cuntada degdega ah, dharka aan tolmada lahayn, warshadaha iyo kuwa madaniga ah laga bilaabo warshadaha ilaa isticmaalka madaniga ah.Ka dibna lagu farsameeyo dharka beeraha, dharka daryeelka caafimaadka, maryaha, alaabta nadaafadda, dharka ka hortagga ultraviolet ee dibadda, dharka teendhada, joodariga sagxadda iyo wixii la mid ah, rajada suuqa ayaa ah mid rajo leh.Waxaa la arki karaa in qalabkiisa makaanikada iyo jireed ay wanaagsan yihiin.

Astaamaha aasaasiga ah ee jirka ee polylactic acid (PLA) iyo balaastigga synthetic petrochemical waa isku mid, taas oo ah in la yiraahdo, waxaa si ballaaran loo isticmaali karaa in lagu sameeyo noocyo kala duwan oo alaabooyin ah.Polylactic acid sidoo kale waxay leedahay dhalaal wanaagsan iyo hufnaan, taas oo la mid ah filimka laga sameeyay polystyrene oo aan lagu siin karin alaabada kale ee biodegradable.
