I-Polylactic acid (PLA), eyaziwa ngokuba yi-polylactide, yi-aliphatic polyester eyenziwe yi-dehydration polymerization ye-lactic acid eveliswa yi-microbial fermentation njenge-monomer. Isebenzisa i-biomass ehlaziyekayo efana nombona, umoba, kunye necassava njengezinto ezikrwada, kwaye inoluhlu olubanzi lwemithombo kwaye inokuvuselelwa. Inkqubo yokuvelisa i-polylactic acid iphantsi kwekhabhoni, ihambelana nokusingqongileyo, kwaye ayingcolisi. Emva kokusetyenziswa, iimveliso zayo zinokudityaniswa kwaye zithotywe ukuqaphela umjikelo kwindalo. Ukongezelela, isetyenziswa ngokubanzi kwaye inexabiso eliphantsi kunezinye iiplastiki eziqhelekileyo ezinokonakala ezifana ne-PBAT, i-PBS, kunye ne-PHA. Ke ngoko, iye yaba yeyona nto isebenzayo kwaye ikhula ngokukhawuleza i-biodegradable imathiriyeli kwiminyaka yakutshanje.

Ukuphuhliswa kwe-polylactic acid kuxabiswa kakhulu kwihlabathi jikelele. Ngo-2019, ezona zicelo ziphambili ze-PLA yehlabathi jikelele kwipakethe kunye neetafile, ukhathalelo lwezonyango kunye nolomntu, iimveliso zefilimu, kunye nezinye iimakethi zokuphela zibalelwa kwi-66%, 28%, 2%, kunye ne-3% ngokulandelelana.

Ukusetyenziswa kwemarike yepolylactic acid kusalawulwa yitafile elahlayo kunye nokupakishwa kokutya kunye nobomi obufutshane beshelufu, ilandelwa yitafile ehlala ixesha elide okanye esetyenziswa kaninzi. Iimveliso zefilimu ezivuthelweyo ezifana neengxowa zokuthenga kunye ne-mulch zixhaswa ngamandla ngurhulumente, kwaye ubungakanani bemarike bunokuba nokutsiba okukhulu kwixesha elifutshane. Imarike yeemveliso zefiber ezilahlayo ezifana ne-diapers kunye ne-sanitary napkins zinokunyuka ngokukhawuleza phantsi kweemfuno zemimiselo, kodwa iteknoloji edibeneyo isadinga impumelelo. Iimveliso ezikhethekileyo, ezifana noshicilelo lwe-3D ngexabiso elincinci kodwa ixabiso elongezelelweyo eliphezulu, kunye neemveliso ezifuna ukusetyenziswa kwexesha elide okanye ubushushu obuphezulu, ezifana ne-electronics kunye nezixhobo zemoto.

Kuqikelelwa ukuba umthamo wonyaka wemveliso ye-polylactic acid emhlabeni jikelele (ngaphandle kweChina) malunga neetoni ze-150,000 kunye nemveliso yonyaka malunga neetoni ze-120,000 ngaphambi kwe-2015. Ngokwemarike, ukusuka kwi-2015 ukuya kwi-2020, imarike ye-polylactic acid iya kukhula ngokukhawuleza. kwizinga lokukhula konyaka elihlanganisiweyo malunga ne-20%, kwaye amathemba emarike mahle.
Ngokumalunga nemimandla, iUnited States iyona siseko esikhulu sokuvelisa i-polylactic acid, ilandelwa yi-China, kunye nesabelo semarike yemveliso ye-14% kwi-2018. Ngokubhekiselele kusetyenziso lwengingqi, i-United States isagcina indawo yayo ehamba phambili. Kwangaxeshanye, ikwalelona lizwe lithumela ngaphandle. Ngo-2018, imakethi yehlabathi ye-polylactic acid (PLA) yayixabisa i-US $ 659 yezigidi. Njengeplastiki eyonakalisayo kunye nokusebenza okugqwesileyo. Abangaphakathi kwimarike banethemba malunga nemarike yexesha elizayo
