PLA (pollactic acid) waa shey noole ah oo loo yaqaan 'biodegraderalable iyo waxyaabaha la isku karo ee laga soo qaatay ilaha dib loo cusbooneysiin karo sida istaarijka galley, sonkorta, ama ilaha kale ee dhirta. PLA waxaa loo arkaa inay amaan u tahay in loo isticmaalo codsiyada kala duwan, oo ay ku jiraan baakadaha cuntada iyo maacuunta. Si kastaba ha noqotee, waxaa muhiim ah in la ogaado in PLA lafteedu aysan ahayn isha nafaqada ama cuntada. Waxaa ugu horrayn loo isticmaalaa sidii shey loogu talagalay baakadaha iyo waxyaabaha la tuuri karo.
Marka pla loo isticmaalo bacaha shaaha, tusaale ahaan, looma jeedin in la cuno. Boorsada shaaha ee 'PLA' waxay u adeegtaa sidii weel loogu talagalay caleemaha shaaha, oo u oggolaanaya inay ku haraan biyo kulul. Mar haddii shaaha la diyaariyo, bacda shaah ee fiberka cagta ayaa caadi ahaan la tuuraa.
Marka laga eego aragtida caafimaadka, PLA guud ahaan waxaa loo arkaa mid aamin ah oo aan ahayn - sunta. Ma sii deynayso kiimikada waxyeelada leh markii loo isticmaalo sida loogu talagalay. Si kastaba ha noqotee, haddii pla lagu dhexmaro tiro badan, waxay sababi kartaa in arimo dheef-shiidka oo la mid ah cunista cunno kasta oo aan ahayn
Haddii aad ka walwalsan tahay nabadgelyada ku saabsan nabadgelyada pla ama wax soo saar gaar ah, had iyo jeer waa fikrad fiican inaad fiiriso baakadaha iyo sumadaha wixii ka mid ah shahaadooyinka ama oggolaanshaha ansixinta sharci-darrada ah, iyo sidoo kale la tashiga mas'uuliyiinta caafimaadka ee ku habboon ama xirfadlayaasha.
