Ndi kusintha kosalekeza kwa chidziwitso cha chilengedwe, makampani odzola zodzoladzola ayambitsanso kusintha kobiriwira pakuyika. Zopaka zamapulasitiki zokhala ndi mafuta achikhalidwe sizingogwiritsa ntchito zinthu zambiri panthawi yopanga, komanso zimayambitsa kuipitsidwa kwakukulu kwa chilengedwe panthawi ya chithandizo chamankhwala. Chifukwa chake, kuyang'ana zida zonyamula zokhazikika kwakhala nkhani yofunika kwambiri pamakampani azodzikongoletsera.
Mapulasitiki opangidwa ndi mafuta
Mapulasitiki opangidwa ndi mafuta ndi mtundu wa pulasitiki wopangidwa kuchokera kumafuta amafuta monga mafuta. Lili ndi mapulasitiki abwino komanso makina, choncho amagwiritsidwa ntchito kwambiri m'madera osiyanasiyana. Makamaka, mapulasitiki opangidwa ndi petroleum amaphatikizapo mitundu yodziwika bwino iyi:
Polyethylene (PE)
Polypropylene (PP)
Polyvinyl chloride (PVC)
Polystyrene (PS)
Polycarbonate (PC)
Mapulasitiki opangidwa ndi petroleum amawongolera zodzikongoletsera chifukwa cha kupepuka kwawo, kulimba komanso kutsika mtengo. Mapulasitiki opangidwa ndi petroleum ali ndi mphamvu zambiri komanso kuuma, kukana kwamankhwala kwabwinoko komanso kusinthika bwino kuposa mapulasitiki achikhalidwe. Komabe, kupanga zinthu zimenezi kumafuna mafuta ambiri a petroleum, zomwe zikuwonjezera kutha kwa zinthu zapadziko lapansi. Kutulutsa kwa CO2 komwe kumapangidwa panthawi yopanga kwake kumakhala kwakukulu ndipo kumakhudza kwambiri chilengedwe. Panthawi imodzimodziyo, mapepala apulasitiki nthawi zambiri amatayidwa mwachisawawa pambuyo pogwiritsidwa ntchito ndipo zimakhala zovuta kuti awonongeke atalowa m'malo achilengedwe, zomwe zimawononga kwambiri nthaka, magwero a madzi ndi nyama zakutchire.
Njira zatsopano zopangira ma CD okhazikika
Mapulasitiki obwezerezedwanso
Pulasitiki yobwezerezedwanso ndi mtundu watsopano wazinthu zopangidwa kuchokera ku zinyalala zamapulasitiki kudzera munjira monga kuphwanya, kuyeretsa, ndi kusungunula. Ili ndi zinthu zofanana ndi pulasitiki ya namwali, koma imagwiritsa ntchito zinthu zochepa kwambiri popanga. Kugwiritsa ntchito mapulasitiki obwezerezedwanso ngati zopangira zodzikongoletsera sikungangochepetsa kudalira mafuta amafuta, komanso kumachepetsa kutulutsa mpweya wa kaboni panthawi yopanga.
Bioplastics
Bioplastic ndi zinthu zapulasitiki zomwe zimapangidwa kuchokera kuzinthu zachilengedwe (monga wowuma, mapadi, ndi zina) kudzera muzowitsa, kaphatikizidwe ndi njira zina. Zili ndi zinthu zofanana ndi mapulasitiki achikhalidwe, koma zimatha kuwononga msanga m'chilengedwe komanso ndizogwirizana ndi chilengedwe. Zopangira za bioplastics zimachokera kuzinthu zosiyanasiyana, kuphatikizapo udzu wa mbewu, zinyalala zamatabwa, ndi zina zotero, ndipo ndizongowonjezedwanso kwambiri.
Zopangira zopangira zina
Kuphatikiza pa mapulasitiki obwezerezedwanso ndi ma bioplastics, palinso zida zina zambiri zokhazikika zomwe zilipo. Mwachitsanzo, zida zopangira mapepala zimakhala ndi zabwino kukhala zopepuka, zobwezerezedwanso komanso zowonongeka, ndipo ndizoyenera kugwiritsidwa ntchito muzopaka zamkati za zodzoladzola. Ngakhale zida zopangira magalasi ndizolemera, zimakhala zolimba kwambiri komanso zimatha kugwiritsidwanso ntchito popanga zodzoladzola zapamwamba. Kuphatikiza apo, pali zinthu zina zatsopano zopangira bio-based composite, zitsulo zopangidwa ndi zitsulo, ndi zina zambiri, zomwe zimaperekanso zosankha zambiri zopangira zodzikongoletsera.
Ma Brand ndi ogula amapeza chitukuko chokhazikika
Kukwaniritsa chitukuko chokhazikika cha zodzoladzola zopakapaka kumafuna kuyesetsa kwamitundu ndi ogula. Pankhani ya mtundu, zida zoyikapo zokhazikika ndi matekinoloje ziyenera kufufuzidwa mwachangu ndikugwiritsidwa ntchito kuti muchepetse zovuta zomwe zimatengera chilengedwe. Nthawi yomweyo, ma brand akuyenera kulimbikitsanso maphunziro a zachilengedwe kwa ogula ndikuwongolera ogula kuti akhazikitse malingaliro okhudzana ndi kadyedwe kobiriwira. Makasitomala akuyenera kulabadira zinthu zopakira zinthu ndikuyika patsogolo zinthu zomwe zili ndi phukusi lokhazikika. Pogwiritsa ntchito, kuchuluka kwa zotengera zomwe zimagwiritsidwa ntchito kuyenera kuchepetsedwa momwe kungathekere, ndipo zotayira zinyalala ziyenera kusankhidwa bwino ndikutayidwa.
Mwachidule, kusintha kobiriwira kwa zodzoladzola zodzoladzola ndi njira yofunikira kuti makampani opanga zodzoladzola akwaniritse chitukuko chokhazikika. Potengera zida zomangira zokhazikika ndi matekinoloje ndikulimbikitsa maphunziro azachilengedwe, ma brand ndi ogula atha kuthandizira tsogolo la dziko lapansi.
