Ndi kupita patsogolo kosalekeza kwa chidziwitso cha chilengedwe, makampani opanga zodzoladzola nawonso ayambitsa kusintha kobiriwira pakuyika zinthu. Mapaketi apulasitiki achikhalidwe ochokera ku mafuta samangogwiritsa ntchito zinthu zambiri panthawi yopanga zinthu, komanso amayambitsa kuipitsa chilengedwe kwambiri panthawi yogwiritsidwa ntchito. Chifukwa chake, kufufuza zinthu zokhazikika pakuyika zinthu kwakhala nkhani yofunika kwambiri mumakampani opanga zodzoladzola.
Mapulasitiki opangidwa ndi mafuta
Mapulasitiki opangidwa ndi mafuta ndi mtundu wa zinthu zopangidwa ndi pulasitiki zopangidwa ndi mafuta monga mafuta. Ali ndi pulasitiki wabwino komanso mphamvu zamakanika, kotero amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana. Makamaka, mapulasitiki opangidwa ndi mafuta amaphatikizapo mitundu yodziwika bwino iyi:
Polyethylene (PE)
Polypropylene (PP)
Polyvinyl chloride (PVC)
Polystyrene (PS)
Polycarbonate (PC)
Mapulasitiki opangidwa ndi mafuta amalamulira ma CD okongoletsera chifukwa cha kupepuka kwawo, kulimba komanso kugwiritsa ntchito bwino ndalama. Mapulasitiki opangidwa ndi mafuta ali ndi mphamvu komanso kuuma kwakukulu, kukana mankhwala komanso kusinthasintha bwino kuposa mapulasitiki achikhalidwe. Komabe, kupanga zinthuzi kumafuna mafuta ambiri, zomwe zimapangitsa kuti zinthu zapadziko lapansi zichepe kwambiri. Mpweya wa CO2 womwe umapangidwa panthawi yopanga zinthu zake ndi wokwera ndipo umakhudza chilengedwe. Nthawi yomweyo, ma CD opangidwa ndi pulasitiki nthawi zambiri amatayidwa mwachisawawa akagwiritsidwa ntchito ndipo zimakhala zovuta kuwonongeka atalowa m'chilengedwe, zomwe zimapangitsa kuti nthaka, madzi ndi nyama zakuthengo ziwonongeke kwambiri.
Mayankho atsopano opangira ma CD okhazikika
Pulasitiki yobwezerezedwanso
Pulasitiki yobwezeretsedwanso ndi mtundu watsopano wa zinthu zopangidwa kuchokera ku pulasitiki yotayidwa kudzera mu njira monga kuphwanya, kuyeretsa, ndi kusungunula. Ili ndi mphamvu zofanana ndi pulasitiki yoyambirira, koma imagwiritsa ntchito zinthu zochepa kwambiri popanga. Kugwiritsa ntchito pulasitiki yobwezeretsedwanso ngati zinthu zodzikongoletsera sikungochepetsa kudalira mafuta okha, komanso kuchepetsa mpweya woipa wa carbon panthawi yopanga.
Zamoyo zopangidwa ndi pulasitiki
Bioplastic ndi zinthu zapulasitiki zomwe zimapangidwa kuchokera ku zinthu zachilengedwe (monga starch, cellulose, ndi zina zotero) kudzera mu kuyatsa kwachilengedwe, kupanga ndi njira zina. Ili ndi mphamvu zofanana ndi za pulasitiki yachikhalidwe, koma imatha kuwonongeka mwachangu m'chilengedwe ndipo ndi yoteteza chilengedwe. Zinthu zopangira za bioplastics zimachokera kuzinthu zosiyanasiyana, kuphatikizapo udzu wa mbewu, zinyalala zamatabwa, ndi zina zotero, ndipo zimatha kubwezeretsedwanso.
Zipangizo zina zopakira
Kuwonjezera pa mapulasitiki obwezerezedwanso ndi mapulasitiki achilengedwe, palinso zinthu zina zambiri zosungiramo zinthu zokhazikika zomwe zilipo. Mwachitsanzo, zinthu zosungiramo mapepala zili ndi ubwino wokhala wopepuka, wobwezerezedwanso komanso wowonongeka, ndipo ndizoyenera kugwiritsidwa ntchito mkati mwa zodzoladzola. Ngakhale kuti zinthu zosungiramo magalasi zimakhala zolemera, zimakhala zolimba komanso zogwiritsidwanso ntchito bwino ndipo zingagwiritsidwe ntchito posungira zodzoladzola zapamwamba. Kuphatikiza apo, pali zinthu zina zatsopano zopangidwa ndi zinthu zachilengedwe, zinthu zopangidwa ndi zitsulo, ndi zina zotero, zomwe zimaperekanso zosankha zambiri zosungira zodzoladzola.
Makampani ndi ogula pamodzi akwaniritsa chitukuko chokhazikika
Kukwaniritsa chitukuko chokhazikika cha ma CD opaka zodzoladzola kumafuna mgwirizano wa makampani ndi ogula. Ponena za makampani, zipangizo zokhazikika zopaka ndi ukadaulo ziyenera kufufuzidwa ndikugwiritsidwa ntchito kuti zichepetse zotsatira zoyipa za ma CD pa chilengedwe. Nthawi yomweyo, makampani ayeneranso kulimbikitsa maphunziro okhudza chilengedwe kwa ogula ndikuwongolera ogula kukhazikitsa mfundo zobiriwira zogwiritsira ntchito. Ogula ayenera kulabadira zinthu zopaka zogulitsa ndikupereka patsogolo zinthu zokhala ndi ma CD okhazikika. Pakugwiritsa ntchito, kuchuluka kwa ma CD ogwiritsidwa ntchito kuyenera kuchepetsedwa momwe kungathekere, ndipo ma CD opaka zinyalala ayenera kugawidwa bwino ndikutayidwa.
Mwachidule, kusintha kobiriwira kwa ma CD a zodzoladzola ndi njira yofunika kwambiri kuti makampani opanga zodzoladzola akwaniritse chitukuko chokhazikika. Mwa kugwiritsa ntchito zipangizo zokhazikika zomangira ndi ukadaulo komanso kulimbitsa maphunziro okhudza chilengedwe, makampani ndi ogula akhoza kuthandizana mtsogolo mwa dziko lapansi.
