Polylactic acid (plu), omwe amadziwikanso kuti Polylactide, ndi a Aliphacter polyerter opangidwa ndi vuto la lactic a acid opangidwa ndi tizilombo toyambitsa matenda ngati monomer. Imagwiritsa ntchitonsonso zipatso monga chimanga, nzimbe za shuga, ndi chinangwa monga zopangira, ndipo zimakhala ndi mitundu yosiyanasiyana ndipo imatha kukhala yosinthika. Kupanga kwa polylactic acid ndi otsika-kaboni, kopenyerera kwachilengedwe, komanso kupukuta pang'ono. Mukatha kugwiritsa ntchito, malonda ake amatha kuphatikizidwa ndikuwonongeka kuti azindikire kuzungulira kwachilengedwe. Kuphatikiza apo, imagwiritsidwa ntchito kwambiri ndipo ili ndi mtengo wotsika kuposa pulasitiki wina wopanda pake monga pbat, mass, ndi pang'ono. Chifukwa chake, zakhala zogwira kwambiri komanso zochulukirapo zomwe zimachitika kwambiri m'zaka zaposachedwa.

Kukula kwa polylactic acid kumakhala kofunika kwambiri padziko lonse lapansi. Mu 2019, ntchito yayikulu kwambiri ya Pulogalamu yapadziko lonse yomwe ikugwiritsidwa ntchito ndi matebulo, chithandizo chamankhwala komanso zinthu zina zomaliza, ndi 3%, 2%, ndi 3% motsatana.

Kugwiritsa ntchito kwa msika wa polylactic acid kumalamulidwabe ndi matayala otayika ndi kunyamula kwa chakudya ndi moyo wa alumali kapena kugwiritsidwa ntchito kochepa. Mafuta owombera mafilimu monga matumba ogulitsira ndi mulch amathandizidwa kwambiri ndi boma, ndipo kukula kwa msika kumatha kukhala ndi kudumpha kwakukulu munthawi yochepa. Msika wotaya zinthu zotayini monga ma diapeki ndi napkins ukhondo ungakwezenso mothandizidwa ndi malamulo, koma tekinoloje yake yopanga imafunikirabe kugwada. Zogulitsa zapadera, monga kusindikiza 3D pamtengo wochepa koma mtengo wowonjezereka, ndi zinthu zomwe zimafunikira kutentha kwapamwamba kapena zamagetsi, monga zamagetsi komanso zamagalimoto.

Akuyerekeza kuti mphamvu ya a acid yapachaka padziko lonse lapansi (kupatula China) ndi matani pafupifupi 120,000.
Potengera madera, United States ndi gawo lalikulu kwambiri lopanga polylactic acid, lotsatiridwa ndi China, ndi gawo la msika wa 14% mu 2018. Potengera maulendo achigawo, United States imasungabe udindo wake. Nthawi yomweyo, ndinso kugonja kwa dziko lalikulu padziko lonse lapansi. Mu 2018, msika wa polylactic acid (prog) pamsika unayandikana ku US $ 659 miliyoni. Ngati pulasitiki yopanda kanthu ndikuchita bwino. Misika Yamsika ali ndi chiyembekezo chokhudza mtsogolo
