Qalabka biodegradable waa maaddooyin si buuxda u jejebin kara xeryahooda molecular hoose by microorganisms (tusaale, bakteeriyada, fangaska, iyo algae, iwm) hoos xaaladaha deegaanka dabiiciga ah ee ku haboon iyo muddada la arki karo. Hadda, waxay inta badan u qaybsan yihiin afar qaybood oo waaweyn: polylactic acid (PLA), PBS, polylactic acid ester (PHA) iyo polylactic acid ester (PBAT).
PLA waxay leedahay badbaado noole, biodegradability, sifooyin farsamo oo wanaagsan iyo habayn sahlan, waxaana si weyn loogu isticmaalaa baakadaha, dunta, filimada caaga ah ee beeraha iyo warshadaha polymer-ka noole.
PBS waxaa loo isticmaali karaa filimada baakadaha, alaabta miiska, alaabta baakadaha xumbo, dhalooyinka maalinlaha ah la isticmaalo, dhalooyinka daawada, filimada beeraha, bacriminta sunta cayayaanka agabka si tartiib tartiib ah loo sii daayo iyo meelo kale.
PHA waxaa loo isticmaali karaa alaabada la tuuri karo, goonnada qalliinka ee qalabka caafimaadka, bacaha iyo bacaha wax lagu kariyo, tolida caafimaadka, qalabka dayactirka, faashado, irbadaha lafaha, filimada ka hortagga adhesion iyo stent.
PBAT waxay leedahay faa'iidooyinka waxqabadka samaynta filim-samaynta wanaagsan iyo afuufista filim ku habboon, waxaana si ballaaran loo isticmaalaa aflaanta baakadaha la tuuri karo iyo filimada beeraha.
