Mu Marichi 2022, Msonkhano Wachisanu wa United Nations Environmental Conference udapitilira kupereka "Plastic Pollution Resolution (Draft)" ku Nairobi, likulu la Kenya. Pamsonkhanowu, mtsogoleri wa dziko, nduna ya chilengedwe ndi oimira ena ochokera m'mayiko 175 adasaina mbiriyi. Lingaliroli likufuna kulimbikitsa ulamuliro wapadziko lonse wochepetsa kuwononga pulasitiki ndipo akuyembekeza kuthetsa kuyipitsa kwa pulasitiki pofika 2024.
Chisamaliro cha zinthu zowonongeka
Malinga ndi lipoti lapitalo lazachilengedwe lomwe linatulutsidwa ndi OECD (Organization for Economic Co-operation andDevelopment), mu 2019, kutulutsa kwapachaka kwazinthu zamapulasitiki padziko lonse lapansi ndi pafupifupi matani 460 miliyoni, ndipo zinyalala zamapulasitiki pachaka zafika matani 353 miliyoni. Zopanga, kuphatikiza ma CD apulasitiki (40 %), zinthu zogula pulasitiki (12), nsalu (11%), ndi zina.
Ndi chitukuko cha ndondomeko, zipangizo zowonongeka zidzapitirira kuwonjezeka.
Mpikisano wa mphamvu zopanga
Pakali pano, pulasitiki yowonongeka pamsika ikhoza kugawidwa m'mitundu iwiri: "petroleum base" ndi "biological base". Kusiyanitsa pakati pa ziwirizi kumagawika makamaka pakupanga zopangira. PBS (polynoxylxylxylxyl glycol), PBAT (alcoholic glycolic glycolin ndi phenyl-dysteenol (polima wamba), PCL (polycopide), ndi zina zotero. chimanga, udzu ndi zinthu zina zamoyo, makamaka PLA (polylactic acid) ndi PHA (polyxide alkyl).
Pakati pa zinthu zomwe zatchulidwa pamwambazi zowonongeka, poyerekeza ndi zinthu zina zowonongeka zamoyo, PLA (polyal acid) ndi mitengo ya PBAT ndi yochepa, ndipo njira yopangira imakhala yokhwima. Waukulu njira mapulasitiki chikhalidwe.
The zopangira za PLA makamaka chimanga ndi udzu. Mukatha kugwiritsa ntchito, imatha kuwola mwachangu kukhala carbon dioxide, madzi ndi mchere wamchere pansi pa kompositi (kompositi yamakampani). (PLA) kupanga kumapanga kuzungulira kwa kaboni.
Tiyenera kudziwitsa anthu za chitetezo cha chilengedwe komanso kuchepetsa kuwonongeka kwa pulasitiki. Zathuyogulitsa thermoforming makina imatha kupanga tableware ya nthawi imodzi ya PLA, ntchito yosavuta komanso yabwino, pulogalamu yanzeru, yomwe ingakwaniritse zosowa zanu zopanga.
