Polylactic acid (PLA) ndi chikwama chatsopano cha pulasitiki chosawonongeka chopangidwa kuchokera ku wowuma wotengedwa kuzinthu zongowonjezwdwanso za mbewu monga chimanga.Ili ndi biodegradability yabwino ndipo imatha kuonongeka kwathunthu ndi tizilombo tating'onoting'ono tachilengedwe ikagwiritsidwa ntchito, kenako imatulutsa mpweya woipa ndi madzi.Siyiyipitsa chilengedwe, imapindulitsa kwambiri kuteteza chilengedwe, imadziwika kuti ndi zinthu zoteteza chilengedwe
M'thumba la pulasitiki losawonongeka, polylactic acid (PLA) imadziwika kuti ndi imodzi mwa mitundu yomwe ili ndi kuthekera kotukuka kwambiri, yokhala ndi mphamvu zofananira ndi biocompatibility, biodegradability ndi kuthekera kopanganso zinthu.M'chilengedwe, zinyalala za PLA zitha kusinthidwa kukhala CO2 ndi H2O kudzera m'njira zingapo zama metabolic achilengedwe monga hydrolysis (miyezi 6-12).CO2 ndi H2O izi zingagwiritsidwe ntchito ndi zomera kupanga wowuma panthawi ya photosynthesis, yomwe ingagwiritsidwe ntchito kupanga polylactic acid kachiwiri.Chifukwa chake, asidi a polylactic sizinthu zosatha, komanso zimatha kuchepetsa kuipitsidwa koyera, kupulumutsa mafuta, komanso zinthu zomwe zimatha kusunga "carbon cycle balance" m'chilengedwe.
Nthawi yeniyeni yomwe imatengera kuti chikwama chobwezerezedwanso chiwole zimadalira zinthu zosiyanasiyana, monga kutentha ndi kuchuluka kwa chinyezi.Matumba opangidwa ndi kompositi amatha kuwonongeka mkati mwa masiku 30 m'malo ogulitsa manyowa komanso mkati mwa masiku 90 m'makina a kompositi kunyumba.
Pakalipano timapanga: matumba a khofi omwe amatha kuwonongeka, matumba a tiyi omwe amatha kuwonongeka.Matumba owonongeka okhala ndi lathyathyathya, chikwama chosindikizira cham'mbali chosawonongeka, matumba oyikamo zakudya, osawonongeka ndi zipi, thumba la 3-mbali ndi zina, katundu wathu akugulitsa mayiko opitilira 20 padziko lonse lapansi, pali milandu ndi zitsanzo zambiri, ngati muli nazo. Kufunika kwa matumba owonongeka, chonde titumizireni, tidzakupatsani mayankho abwino kwambiri, Lolani kuti malonda anu azigulitsa bwino.Ndipo gwirani ntchito nafe kuteteza dziko lapansi.
