Polyethylene yotsika kachulukidwe (LDPE) ndiye chida chomwe chimagwiritsidwa ntchito kwambiri popaka mapepala pamapepala.Polylactic acid (PLA) ndi yachiwiri kwa iyo, yowerengera kuposa 5% yamsika pamsika, zomwe zasintha kwambiri poyerekeza ndi zaka 5 zapitazo.Komabe, kafukufuku waposachedwa komanso kafukufuku wa bioplastics wayambitsa kufufuza kwa moyo pakulimbikitsa kwa PLA ndi polybutylene adipate terephthalate (PBAT).Zomwe zapeza zatsopano zakhudzanso kugwiritsa ntchito kwake mu tableware yotayika.
Pa Juni 29, 2023, Environmental Protection Administration (EPA) ku Taiwan, idalengeza zaletsa kugwiritsa ntchito tableware opangidwa kuchokera ku PLA, m'malo odyera, m'masitolo ogulitsa komanso m'mabungwe oyendetsedwa ndi anthu zomwe zidayamba kugwira ntchito pa Oga 1, 2023.
Pakadali pano, kupangidwa kwa zinthu zatsopano zozikidwa pazamoyo kumakula bwino.Tengani chitsanzo cha PHA.Masiku ano, yalimbana ndi njira zake zopanga ngakhale zaka zambiri zamaphunziro amalingaliro ndi mayeso a labotale.Chaka chatha, pulojekiti yoyamba ya Bluepha™️ ku Yancheng ya Jiangsu idayamba kupanga ndikutulutsa matani 5,000 pachaka.Ndizofunikira kudziwa kuti ntchito yake yachiwiri ndi yachitatu yatsala pang'ono kutha ndi kuchuluka kwa matani masauzande a biopolymer owonongeka m'madzi.
Motsogozedwa ndi kufunikira kwa makasitomala a mapepala, kufunikira kopanga zokutira zokhala ndi madzi monga chotchinga chowonongeka chafika patsogolo.Mapepala ndi bolodi amadziwika ngati zinthu zowonongeka.Zotchingira zotchinga zobalalika monga njira zochepetsera kudalira kwake pazigawo zapulasitiki pazinthu zotchinga ndizopikisana kwambiri komanso zimalonjeza.Komabe, tsogolo lokhazikika la unyolo wamtengo wapatali lidzafunika ndalama zambiri komanso kafukufuku wopangidwa ndi makampani kuti apangitse zinthu zatsopano ndikukweza.
