Raws li ib puag ncig kev paub txog kev loj hlob, kev thov rau lwm txoj hauv kev rau cov khoom siv yas pov tseg ib txwm tau nce ntxiv.PLA (polylactic acid) biodegradable tableware, ua los ntawm cov khoom siv txuas ntxiv dua tshiab xws li pob kws thiab hmoov txhuv nplej siab, tsis ntev los no tau muaj koob meej hauv khw noj mov thiab khoom noj khoom haus, dhau los ua qhov chaw ci ntsa iab tshiab hauv kev lag luam ntsuab.

Cov neeg sau xov xwm tau mus xyuas ntau lub tuam txhab noj mov thiab pom tias cov khw muag khoom lag luam tau ua tiav qhov kev hloov pauv mus rau tag nrhoPLA khoom plig. Nayuki's Tea lub taub hau ntawm kev ruaj ntseg tau qhia tias lub hom lag luam tau hloov pauv mus rau eco-phooj ywg cov ntaub ntawv rau straws, cutlery hnab, thiab lwm yam ntaub ntawv txij li xyoo 2021. Lub hom siv ntau tshaj 30 lab teeb ntawm PLA tableware txhua xyoo, txo kev siv cov yas uas tsis yog degradable los ntawm 350 tons hauv 2021 ib leeg los ntawm kev hloov cov phooj ywg. "Tom qab hloov mus rau PLA tableware, qhov feem pua ​​​​ntawm cov kev tshuaj xyuas zoo muaj feem xyuam rau 'ib puag ncig tus phooj ywg ntim' hauv kev txiav txim nqa tawm tau nce mus rau 22%, qhov nce 15 feem pua."

Nyob rau sab ntau lawm, PLA kev lag luam tableware yog tsav los ntawm ob txoj cai thiab kev lag luam rog. Xyoo no, Guizhou, Beijing, thiab lwm lub nroog tau siv zog txhim kho "kev txwv yas, "hais meej yuav tsum tau txo qis 30% ntawm kev noj cov khoom noj uas tsis yog degradable hauv cov khoom noj thiab cov khoom noj khoom haus hauv cov nroog ntawm lossis siab dua qib prefecture los ntawm qhov kawg ntawm 2025. Tau ntsib cov kev cai zoo, cov tuam txhab xws li Hengxin Txoj Kev Ua Neej tau nthuav dav ntau lawm. Nws Hainan ntau lawm puag tau ntxiv peb PLA tableware ntau lawm kab, nce nws cov peev txheej ntau dua 6 xyoo, kwv yees li 0 tons. 600-800 lab pieces ntawm tableware txhua xyoo Nws lub Hoobkas Thaib tseem ua tiav nws cov khoom xa tuaj thawj zaug hauv lub Plaub Hlis, nws cov khoom tau nkag mus rau Asmeskas cov khoom noj ceev thiab dav hlaukev lag luam khoom noj khoom haus, tsim cov nyiaj tau los tag nrho tshaj li 31%.

Txawm li cas los xij, qee cov neeg siv khoom tseem muaj kev txhawj xeeb txog cov neeg siv kev paub ntawm PLA tableware. R&D Tus Thawj Coj ntawm Biomaterials ntawm Kingfa Technology tau piav qhia, "Peb cov khoom tsim PLA cov khoom siv loj yog cov cua sov-tiv taus txog 120 ° C thiab, raws li kev sim thib peb, tuaj yeem tiv taus cov roj kub kub thiab dej kub npau npau. Cov neeg sab hauv kev lag luam kwv yees tias, tau txais txiaj ntsig los ntawm kev tsim kho thev naus laus zis thiab kev txo nqi, kev lag luam PLA hauv tsev yuav tsum tshaj 1.8 lab tons hauv 2025, sib xws rau kev lag luam loj ze li ntawm 50 billion yuan.
