Pansi pa funde lapadziko lonse lachitukuko chokhazikika, acid-grade polylactic acid(PLA) tebuloikukhala gwero lalikulu la kusintha kobiriwira kwa makampani operekera zakudya ndi njira yosaletseka, ndipo chiyembekezo chake pamsika wapadziko lonse lapansi ndi chowala.

Kuteteza zachilengedwe ndiye chinthu chofunikira kwambiri chomwe chimapangitsa kuti zakudya zamtundu wa PLA ziziwoneka bwino pamsika wapadziko lonse lapansi. Ndi kudzutsidwa kosalekeza kwa chidziwitso cha chilengedwe cha ogula padziko lonse lapansi, anthu akuyang'anitsitsa kwambiri kuwonongeka kwa chilengedwe komwe kumachitika chifukwa cha miyambo yakale.pulasitiki tableware. Malinga ndi kafukufuku wa bungwe la United Nations Environment Programme, pafupifupi matani 8 miliyoni a zinyalala zapulasitiki zimathamangira m’nyanja chaka chilichonse. PLA tableware amagwiritsa ntchito zomera zongowonjezwdwa monga chimanga ndi nzimbe ngati zipangizo. M'malo opangira kompositi m'mafakitale, chiwopsezocho chikhoza kufika kupitirira 90% m'miyezi 6 yokha, ndipo pamapeto pake amawola kukhala carbon dioxide ndi madzi, zomwe zimachepetsa kwambiri vuto la kuipitsidwa kwa pulasitiki. Mwachitsanzo, pamasewera a Olimpiki a Zima ku Beijing a 2022, chochitikacho chidatengera pulogalamu ya PLA, kuwonetsa dziko lapansi kuthekera kwakugwiritsa ntchito kwake kwakukulu, komwe kudakopa chidwi ndikutsanzira anthu ambiri.okonza zochitika zazikulupadziko lonse lapansi. pa

Chitetezo ndichitsimikizo chofunikira pazakudya zamagulu a PLA kuti athe kudalira ogula padziko lonse lapansi. Zatsimikiziridwa ndi mabungwe ovomerezeka padziko lonse lapansi monga US Food and Drug Administration (FDA) ndi European Food Safety Authority (EFSA), kuonetsetsa kuti ilibe zinthu zovulaza monga plasticizers ndi bisphenol A. Mosiyana kwambiri, melamine tableware yachikhalidwe ikhoza kutulutsa carcinogens monga formaldehyde pansi pa kutentha kwakukulu kapena malo enaake, pamene PLA ikuwonetseratu zinthu zomwe zimagwira ntchito bwino.chitetezo cha chakudyaapangitsa kuti azigwiritsidwa ntchito kwambiri m'malo omwe ali ndi zofunikira zachitetezo chapamwamba kwambiri monga nyumba, masukulu, ndi zipatala padziko lonse lapansi.

Motsogozedwa ndi luso laukadaulo, magwiridwe antchito a chakudyaPulogalamu ya PLAwakhala akukometsedwa mosalekeza ndipo zochitika zake zogwiritsiridwa ntchito zawonjezedwanso. Kupyolera mu kusinthidwa kwa crystallization, kutentha kwake kwa kutentha kwawonjezeka kwambiri kuchokera ku 56 ° C mpaka 132 ° C; pambuyo kusakanikirana ndi PBAT, kutalika kwake panthawi yopuma kwawonjezeka kufika pa 100%, zomwe zingathe kukwaniritsa zosowa za phukusi lachisanu. Komanso, makhalidwe ake otsika kutentha processing osati kuchepetsa mphamvu ya mphamvu ndi 30%, koma akhoza kusinthidwa kwa zida za pulasitiki alipo kale, kukopa ambiri Catering makampani ndi opanga padziko lonse. Ku Ulaya ndi ku United States, maunyolo owonjezereka a chakudya chachangu ayamba kugwiritsa ntchito mabokosi a PLA; ku Asia, masitolo ogulitsa ku Japan agwiritsanso ntchito filimu ya PLA yodzaza chakudya
Pankhani ya ndondomeko, maiko ambiri padziko lonse lapansi adayambitsa ndondomeko zoyenera kuteteza chitukuko cha msika wa tableware wa PLA. China ikugwiritsa ntchito mfundo yobwezera VAT kwa opanga PLA, ndipo ikufuna kuchepetsedwa ndi 30% pazinthu zosawonongeka.pulasitiki tablewarem'munda wotengerako kudzera mu 2025 "Pulasitiki Ban"; European Union yayika ma euro 300 miliyoni mu dongosolo la Horizon Europe, ladzipereka kukwaniritsa 100% yobwezeretsanso zinyalala za PLA pofika 2030; California ndi madera ena ku United States aperekanso malamulo oletsa pulasitiki motsatizana kulimbikitsa kugwiritsa ntchito zinthu zosawonongeka monga PLA. Kukhazikitsidwa kwa mfundozi kwalimbikitsa kukula kwachangu kwa msika wazinthu zamagulu a PLA. pa

Zambiri zamsika zimawonetsa mwachindunji kuthekera kwakukulu kwazakudya zamtundu wa PLA. Malinga ndi lipoti la China Research and Consulting, kukula kwa msika wapadziko lonse wapadziko lonse lapansi kwafika pa US $ 12.2 biliyoni mu 2024 ndipo akuyembekezeka kukula mpaka US $ 18.6 biliyoni pofika 2034. Hengxin Life, kampani yotsogola pantchitoyi, ipeza ndalama zokwana yuan 1.594 biliyoni mchaka cha 2024, komanso chiwonjezeko choyamba cha 7% pazaka 7. kotala la 2025. Ndalama zake kuchokera kuzinthu zowonongeka zimakhala zoposa 54%, zomwe zakopa chidwi cha ndalama zapadziko lonse ku makampani a PLA tableware. pa
Ngakhale pali chiyembekezo chokulirapo, kutukuka kwa ma tableware a PLA pamsika wapadziko lonse lapansi kumakumanabe ndi zovuta zina, monga kusakwanira kwa kutentha kwa zinthu zosasinthika komanso kuwonongeka kwa chilengedwe komwe kumakhudzidwa ndi kutentha. Komabe, ndi ndalama zopitilira kafukufuku zasayansi padziko lonse lapansi, mavutowa akuwongolera pang'onopang'ono. Zitha kudziwikiratu kuti motsogozedwa ndi zosowa zachitetezo cha chilengedwe, chithandizo cha mfundo ndi kupita patsogolo kwaukadaulo, zida zamagulu a PLA zokhala ndi chakudya zitenga malo ofunikira kwambiri pamsika wapadziko lonse lapansi ndikutsogolera makampani opanga zakudya kukhala nthawi yatsopano yazakudya.chitetezo chachilengedwe chobiriwira.
