Polylactic acid (PLA), tseem hu ua kev sib txuas, yog ib qho alphatic polyester ua los ntawm lub cev qhuav dej polymerization ntawm lactic fermentation raws li monomer. Nws siv cov biomass txuas ntxiv xws li pob kws, kab tsib, qab zib yog cov khoom nyoos, thiab muaj ntau qhov chaw thiab tuaj yeem txuas ntxiv mus txuas ntxiv. Cov txheej txheem ntau lawm ntawm polylactic acid yog cov roj carbon tsawg, ib puag ncig phooj ywg, thiab tsis txhob muaj kuab lom. Tom qab siv tas, nws cov khoom tuaj yeem ua kom tiav thiab ua kom pom tseeb kom paub lub voj voog hauv xwm. Ib qho ntxiv, nws tau siv dav siv thiab muaj tus nqi qis dua li lwm cov huab cua uas muaj teeb meem xws li PBAT, PBS, thiab PS. Yog li ntawd, nws tau dhau los ua qhov kev nquag tshaj plaws thiab loj hlob-loj hlob biodegradable cov khoom nyob rau xyoo tsis ntev los no.

Kev txhim kho polylactic acid yog muaj nuj nqis heev rau ntiaj teb. Hauv 2019, lub ntiaj teb Pla cov ntawv thov tseem ceeb hauv kev ntim khoom thiab tableware, thiab lwm yam kev ua yeeb yam ntawm tus kheej thiab lwm yam kev ua yeeb yaj kiab rau 66%, 28%, thiab 3% feem.

Kev ua lag luam daim ntawv thov polylactic acid tseem muaj cov ntaub ntawv txheej thiab cov zaub mov ntim nrog lub neej luv, ua raws li kev siv sijhawm ntev lossis siv cov khoom siv. Blown zaj duab xis khoom xws li lub hnab kav khw thiab mulch muaj kev txhawb nqa loj, thiab cov lag luam loj yuav muaj lub sijhawm loj loj hauv lub sijhawm luv luv. Kev ua lag luam rau cov khoom siv fiber ntau xws li cov pawm thiab huv si kuj tseem tuaj yeem nce raws li cov kev cai ntawm cov kev cai tseem xav tau kev sib tawg. Cov khoom lag luam tshwj xeeb, xws li 3D luam tawm me me tab sis cov khoom lag luam uas xav tau siv ntev lossis siv hluav taws xob ntev li hluav taws xob thiab cov tsheb txuas ntxiv.

Nws yog kwv yees tias txhua xyoo ntau dua cov muaj peev xwm loj hlob thoob ntiaj teb yog li ntawm 20% rau xyoo 2015. Nyob rau xyoo 2015.
Nyob rau hauv cov nqe lus ntawm thaj chaw, Tebchaws Asmeskas yog cov loj tshaj plaws tsim ntawm cov phooj ywg hauv cheeb tsam xyoo 2018. Nyob rau tib lub sijhawm, nws kuj yog lub ntiaj teb exporter. Nyob rau hauv 2018, lub ntiaj teb polylactic acid (PLA) kev lag luam tau muaj txiaj ntsig ntawm Asmeskas $ 659 lab. Raws li ib qho degradable yas nrog kev ua tau zoo. Cov neeg ua lag luam cov neeg ua lag luam tau zoo txog kev ua lag luam yav tom ntej
