M'zaka zaposachedwapa, ndi chidziwitso chowonjezereka cha chitetezo cha chilengedwe, anthu akuyang'ana kwambiri kukhazikika kwa zinthu za tsiku ndi tsiku. Zosefera za khofi zitha kuwoneka ngati kufunikira kofala m'miyambo yambiri yam'mawa, koma akupeza chidwi chifukwa cha compostability yawo. Izi zimadzutsa funso: Kodi zosefera za khofi zitha kupangidwa ndi manyowa?
Pali zida ziwiri zazikulu zosefera khofi: mapepala ndi zitsulo. Zosefera zamapepala ndizofala kwambiri ndipo nthawi zambiri zimapangidwa kuchokera ku ulusi wa cellulose kuchokera kumitengo. Komano, zosefera zitsulo, zomwe nthawi zambiri zimapangidwa ndi chitsulo chosapanga dzimbiri, zimapereka njira yogwiritsira ntchito zosefera zamapepala.
Zosefera za khofi zamapepala nthawi zambiri zimakhala zokometsera, koma pali zina zomwe muyenera kuziganizira. Zosefera zapapepala zoyera nthawi zambiri zimapangidwa kuchokera ku pepala loyera, lomwe lingakhale ndi mankhwala monga chlorine. Ngakhale kuti mankhwalawa amathandizira kuti blekning, amalepheretsa kupanga kompositi ndipo amatha kusiya zotsalira zovulaza. Komabe, zosefera za pepala zosakanizidwa, zomwe zimapangidwa kuchokera ku ulusi wachilengedwe ndipo sizigwiritsa ntchito mankhwala, zimaonedwa kuti ndizoyenera kupanga kompositi.
Zosefera zachitsulo ndi njira yabwino kwa iwo omwe akhudzidwa ndi kuchepetsa zinyalala. Zosefera zachitsulo zogwiritsidwanso ntchito sizimangochotsa kufunikira kwa zosefera zamapepala zotayidwa komanso zimapereka yankho lokhazikika kwanthawi yayitali. Mwa kungotsuka ndi kugwiritsanso ntchito, zosefera zitsulo zimachepetsa kwambiri kuwonongeka kwa chilengedwe kwa zosefera zamapepala zomwe zimatha kutaya.
The compostability wa zosefera khofi zimatengeranso njira kutaya. M'kachitidwe ka kompositi ya kuseri kwa nyumba, zosefera za mapepala, makamaka zosefera za pepala zosasungunuka, zimawola mwachilengedwe pakapita nthawi, ndikupereka zinthu zamtengo wapatali kunthaka. Komabe, ngati atatayidwa pamalo otayiramo zinthu momwe zinthu zachilengedwe zimawola movutikira, zosefera za khofi sizingawole bwino ndipo zimatha kutulutsa mpweya wa methane.
Pozindikira kufunikira kwakukula kwa njira zokhazikika zopangira khofi, ambiri opanga zosefera za khofi tsopano akupereka njira zopangira kompositi. Zosefera izi nthawi zambiri zimapangidwa kuchokera kuzinthu zobwezerezedwanso kapena ulusi wazomera monga nsungwi kapena hemp. Posankha njira izi, okonda khofi amatha kusangalala ndi zakumwa zawo za tsiku ndi tsiku ndi mtendere wamaganizo, podziwa kuti zosefera zawo zimabwerera padziko lapansi popanda vuto.
Mwachidule, compostability ya fyuluta ya khofi imadalira zinthu zosiyanasiyana, kuphatikizapo zinthu, bleaching process, ndi kutaya. Ngakhale zosefera zamapepala, makamaka zosapangidwa ndi bleached, nthawi zambiri zimakhala compostable, zosefera zazitsulo zimapereka njira yogwiritsiridwa ntchito komanso yosamalira chilengedwe. Pokhala ndi compostable options zowonjezereka, ogula tsopano ali ndi mwayi wogwirizanitsa zizoloŵezi zawo za khofi ndi zikhalidwe zokhazikika, kuonetsetsa kuti chikho chilichonse cha khofi chimakhala ndi zotsatira zabwino padziko lapansi.
Ttonchant wakhala akudzipereka pachitetezo cha chilengedwe, ndipo zosefera za khofi zomwe amapanga ndizinthu zowonongeka.
