Jakunkunan marufi masu lalacewa, abin da ake nufi yana da lalacewa, amma jakunkunan marufi masu lalacewa sun kasu zuwa "lalata" da "cikakken lalacewa" biyu. Deradable marufi jakar tana nufin samar da tsari don ƙara wani adadin Additives (kamar sitaci, modified sitaci ko sauran cellulose, photosensitizer, biodegradative wakili, da dai sauransu), sabõda haka, da kwanciyar hankali na filastik marufi jakar, sa'an nan kwatanta sauki zuwa ga. ƙasƙanci a cikin yanayin yanayi. Jakar marufi mai cike da lalacewa tana nufin jakar marufi na filastik gaba ɗaya ta lalace zuwa ruwa da carbon dioxide. Babban tushen wannan abu mai lalacewa ana sarrafa shi zuwa lactic acid, wato PLA, daga masara da rogo.

Polylactic acid (PLA) wani sabon nau'in nau'in halitta ne na halitta da abin da za'a iya sabuntawa. Ana samun glucose daga albarkatun sitaci ta hanyar saccharification, sa'an nan kuma lactic acid tare da tsafta mai girma yana haifuwa daga glucose da wasu nau'ikan nau'ikan, sannan polylactic acid tare da wani nau'in nau'in kwayar halitta yana haɓaka ta hanyar haɗin sinadarai.
