Polylactic acid (PLA), inozivikanwawo sepolylactide, is aliphatic polyester yakagadzirwa nedehydration polymerization yelactic acid inogadzirwa nemicrobial fermentation semonomer. Inoshandisa biomass inogona kudzokororwa sechibage, nzimbe, uye mufarinya sezviyo, uye ine zvakawanda zvakasiyana-siyana uye inogona kuvandudzwa. Iyo nzira yekugadzira ye polylactic asidhi yakaderera-kabhoni, inoshamwaridzana nenharaunda, uye kushoma kusvibisa. Mushure mekushandiswa, zvigadzirwa zvayo zvinogona kuumbwa uye kuderedzwa kuti zvione kutenderera mune zvakasikwa. Pamusoro pezvo, inoshandiswa zvakanyanya uye ine mutengo wakaderera pane mamwe akajairika mapurasitiki anoparara akadai sePBAT, PBS, uye PHA. Naizvozvo, yave yakanyanya kushanda uye inokurumidza kukura biodegradable zvinhu mumakore achangopfuura.

Kugadzirwa kwepolylactic acid kunokosheswa pasi rose. Muna 2019, iyo yepasi rose PLA's main applications mukurongedza uye tableware, kurapwa uye kuchengetwa kwemunhu, zvigadzirwa zvemufirimu, uye mimwe misika yekupedzisira yakaverengera 66%, 28%, 2%, uye 3% zvichiteerana.

Iko kushandiswa kwemusika kwepolylactic acid kuchiri kutungamirwa nekuraswa tafuraware uye chikafu chekurongedza nehupenyu hupfupi hwesherufu, ichiteverwa nehafu-yakasimba kana yakawanda-kushandisa tableware. Zvigadzirwa zvemafirimu zvinoputika semabhegi ekutenga uye mulch zvinotsigirwa zvakanyanya nehurumende, uye saizi yemusika inogona kunge iine kusvetuka kukuru munguva pfupi. Musika wezvigadzirwa zvinoraswa zvefiber zvakaita semanapukeni uye napkins dzehutsanana zvinogona zvakare kusimuka zvakanyanya pasi pezvinodiwa nemirairo, asi tekinoroji yayo yemubatanidzwa ichiri kuda budiriro. Zvigadzirwa zvakakosha, senge 3D kudhinda mune diki asi yakakwira kukosha, uye zvigadzirwa zvinoda kushandiswa kwenguva refu kana kwepamusoro-tembiricha, semagetsi nemidziyo yemotokari.

Zvinofungidzirwa kuti gore negore kugadzirwa kwe polylactic acid pasi rose (kunze kweChina) inenge 150,000 matani uye gore negore rinobuda rinenge 120,000 matani asati asvika 2015. Maererano nemusika, kubva ku2015 kusvika ku2020, misika yepasi rose yepolylactic acid ichakura nokukurumidza. pamwero wepagore wekukura ungangoita 20%, uye tarisiro yemusika yakanaka.
Maererano nematunhu, United States ndiyo yakakura yekugadzirwa kwepolylactic acid, inoteverwa neChina, ine mugove wemusika wekugadzira we14% muna 2018. Maererano nekushandiswa kwenharaunda, United States ichiri kuchengetedza nzvimbo yayo inotungamira. Panguva imwe cheteyo, ndiro zvakare guru rekutengesa kunze kwenyika. Muna 2018, musika wepasi rose wepolylactic acid (PLA) waikosheswa paUS$659 miriyoni. Sepurasitiki inoshatisa ine kuita kwakanakisa. Market insiders vane tarisiro pamusoro pemusika weramangwana
