I-Polylactic acid (PLA), eyaziwa nangokuthi i-polylactide, i-aliphatic polyester eyenziwe nge-dehydration dengwane ye-polymerization ye-lactic acid ekhiqizwa ukuvutshelwa kwe-microbial njenge-monomer. Isebenzisa i-biomass evuselelekayo efana nommbila, umoba, kanye nomdumbula njengezinto zokwakha, futhi inezinhlobonhlobo zemithombo futhi ingavuselelwa. Inqubo yokukhiqiza ye-polylactic acid iphansi-ikhabhoni, imvelo inobungane, futhi nokungcoliswa okuncane. Ngemuva kokusebenzisa, imikhiqizo yayo ingahlanganiswa futhi iyonakaliswa ukuze ibone umjikelezo wemvelo. Ngaphezu kwalokho, isetshenziswa kabanzi futhi inezindleko eziphansi kunamanye amapulasitiki ajwayelekile ancipha njenge-Pbat, PBS, ne-PA. Ngakho-ke, sekuyinto ekhule kakhulu futhi ekhula ngokushesha kakhulu endabeni ye-bioderiodegradable endabeni yamuva.

Ukuthuthukiswa kwe-polylactic acid kubaluleke kakhulu emhlabeni jikelele. Ngo-2019, izinhlelo zokusebenza eziphambili ze-Pla zomhlaba wonke ekuphangethweni kanye ne-Tableware, ukunakekelwa kwezokwelapha kanye nokunakekelwa komuntu siqu, imikhiqizo yefilimu, nezinye izimakethe zokuphela ezibalwa ngo-66%, 28%, 2% ngokulandelana.

Ukusetshenziswa kwemakethe kwe-polylactic acid kusabuswa i-Tableware elahlekile nokupakisha kokudla ngempilo emfushane yeshalofu, kulandelwe yi-Semi-Retable Imikhiqizo yefilimu eshaywayo efana nezikhwama zokuthenga kanye ne-mulch zisekelwa kakhulu nguhulumeni, futhi usayizi wemakethe ungahle ube nokugxuma okukhulu esikhathini esifushane. Imakethe yemikhiqizo ye-fiber elahlekile efana nama-diapers kanye nama-napkin ahlanzekile nawo angavuka kakhulu ngaphansi kwezidingo zemithethonqubo, kepha ubuchwepheshe bayo obuhlanganisiwe busadinga ukuphumelela. Imikhiqizo ekhethekile, njengokuphrinta kwe-3D ngenani elincane kodwa inani eliphakeme elingeziwe, nemikhiqizo edinga ukusetshenziswa okuphezulu noma okushisa okuphezulu, njengezesekeli ze-elekthronikhi nezesekeli zemoto.

Kulinganiselwa ukuthi umthamo wokukhiqiza waminyaka yonke we-polylactic acid emhlabeni wonke (ngaphandle kweChina) cishe amathani angama-150,000 futhi okuphumayo konyaka kungama-20,000 emakethe ka-200,000 ngaphambi kuka-20%, futhi amathemba emakethe alungile.
Ngokuya kwezifunda, i-United States iyisisekelo esikhulu kunazo zonke sokukhiqiza se-polylactic acid, elandelwa yiChina, ngesabelo semakethe yokukhiqiza esingu-14% ngonyaka we-14%. Ngasikhathi sinye, futhi i-Free Prest Free. Ngo-2018, imakethe ye-Global Polylactic acid (PLA) yabhekwa e-US $ 659 million. Njengopulasitiki olulahlekile ngokusebenza okuhle kakhulu. Ama-Market Inshiders anethemba ngemakethe yesikhathi esizayo
