III. Chitetezo cha chilengedwe cha Kraft paper ice cream cup
Kraft paper ice cream cup ndi biodegradable and recyclable, zomwe zingachepetse kuwononga chilengedwe. Ndipo ikhoza kuthandizira cholinga cha chitukuko chokhazikika. Monga chisankho chokonda zachilengedwe, makapu a ayisikilimu a Kraft amatha kukwaniritsa zosowa za ogula. Panthawi imodzimodziyo, imatha kuteteza chilengedwe ndikupanga tsogolo lokhazikika.
A. Biodegradation ndi recyclability
Kapu ya ayisikilimu ya Kraft paper imapangidwa ndi ulusi wachilengedwe, motero imatha kuwonongeka komanso kubwezeredwanso
1. Biodegradability. Pepala la Kraft limapangidwa ndi ulusi wa zomera, ndipo chigawo chake chachikulu ndi cellulose. Ma cellulose amatha kuwola ndi tizilombo tating'onoting'ono ndi ma enzymes m'chilengedwe. Pamapeto pake, imasandulika kukhala organic matter. Mosiyana ndi izi, zinthu zosawonongeka monga makapu apulasitiki zimafunikira zaka makumi kapena kupitilira kuti ziwole. Izi zidzachititsa kuti chilengedwe chiwonongeke kwa nthawi yaitali. Kapu ya ayisikilimu ya Kraft paper imatha kuwonongeka mwachilengedwe pakanthawi kochepa. Izi zimapangitsa kuti nthaka isaipitsidwe ndi magwero a madzi.
2. Kubwezeretsanso. Makapu amapepala a Kraft amatha kubwezeretsedwanso ndikugwiritsidwanso ntchito. Kubwezeretsanso moyenera ndi chithandizo kumatha kusintha makapu a ayisikilimu otayidwa a Kraft kukhala zinthu zina zamapepala. Mwachitsanzo, makatoni, mapepala, ndi zina zotero. Izi zimathandiza kuchepetsa kuwononga nkhalango ndi zinyalala za zinthu, ndi kukwaniritsa cholinga chobwezeretsanso.
B. Kuchepetsa kuwononga chilengedwe
Poyerekeza ndi makapu apulasitiki ndi zipangizo zina, makapu a ayisikilimu a Kraft amatha kuchepetsa kuwononga chilengedwe.
1. Chepetsani kuwonongeka kwa Pulasitiki. Makapu a ayisikilimu a pulasitiki nthawi zambiri amapangidwa ndi mapulasitiki opangidwa monga polyethylene (PE) kapena polypropylene (PP). Zidazi siziwonongeka mosavuta ndipo zimangowonongeka mosavuta m'chilengedwe. Mosiyana ndi izi, makapu amapepala a Kraft amapangidwa kuchokera ku ulusi wachilengedwe. Sichidzayambitsa kuwonongeka kwa Pulasitiki ku chilengedwe.
2. Chepetsani kugwiritsa ntchito mphamvu. Kupanga makapu apulasitiki kumafuna mphamvu zambiri. Izi zikuphatikizapo kuchotsa zinthu, kupanga, ndi kayendedwe. Kupanga kapu ya Kraft paper ayisikilimu ndikosavuta. Zitha kuchepetsa kugwiritsa ntchito mphamvu komanso kuchepetsa kufunikira kwa mafuta oyaka.
C. Thandizo lachitukuko chokhazikika
Kugwiritsa ntchito makapu a ayisikilimu a Kraft a pepala kumathandiza kuthandizira cholinga cha chitukuko chokhazikika.
1. Kugwiritsa Ntchito Zongowonjezera. Pepala la Kraft limapangidwa kuchokera ku ulusi wa zomera, monga mapadi amitengo. Ma cellulose a zomera atha kupezeka kudzera mu kasamalidwe kokhazikika ka nkhalango ndi kulima. Izi zitha kulimbikitsa thanzi komanso kugwiritsa ntchito nkhalango mokhazikika. Nthawi yomweyo, kupanga makapu a ayisikilimu a Kraft pamafunika madzi ndi mankhwala ochepa. Izi zitha kuchepetsa kugwiritsiridwa ntchito kwa zinthu zachilengedwe.
2. Maphunziro a zachilengedwe ndi kupititsa patsogolo chidziwitso. Kugwiritsa ntchito Kraftmapepala ayisikilimu makapuakhoza kulimbikitsa kutchuka ndi kupititsa patsogolo chidziwitso cha chilengedwe. Posankha zinthu zokonda zachilengedwe, ogula amatha kumvetsetsa momwe amagulira zinthu zachilengedwe. Izi zitha kukulitsa kuzindikira kwa anthu zachitetezo cha chilengedwe ndikulimbikitsa chitukuko chokhazikika.
