Ma paketi ambiri a khofi achikhalidwe amagwiritsa ntchito zigawo zingapo za pulasitiki ndi aluminiyamu, zomwe zimakhala zovuta kuzibwezeretsanso. Zipangizozi nthawi zambiri zimathera m'malo otayira zinyalala kapena kuwotcha, zomwe zimatulutsa zinthu zovulaza m'chilengedwe. Pamene ogula akuyamba kuganizira kwambiri za chilengedwe, makampani akukakamizidwa kuti agwiritse ntchito njira zosungira zinthu zokhazikika.

Tongshang ndi munthu wotsogoleraKampani yopanga khofi yomwe ili ku Hangzhou, China, ikuyang'ana kwambiri pakupanga khofi watsopano komanso wosawononga chilengedwe. Pokhala ndi zaka zoposa khumi akugwira ntchito, Tongshang imadziwika bwino popanga zosefera za khofi zomwe zimawola, zophikidwa ndi kubwezeretsedwanso, matumba a khofi wothira madzi, matumba a nyemba za khofi ndi matumba akunja opakitsira. Kampaniyo imagwira ntchito ndi makampani apadziko lonse lapansi a khofi kuti apereke ma pakeji omwe samangotsimikizira kuti zinthu zili bwino komanso amachepetsa kuipitsa chilengedwe.

Yankho lofunika kwambiri ndikugwiritsa ntchito zinthu zochokera ku zomera, monga pepala la kraft lopakidwa PLA (polylactic acid). Zinthuzi zimatha kupangidwa ndi manyowa mokwanira ndipo zimatha kuchepetsa kudalira mafuta opangidwa ndi zinthu zakale. Tonchant imaperekanso mafilimu obwezerezedwanso omwe ndi osavuta kugwiritsa ntchito ndikubwezeretsanso popanda njira yovuta yopangira lamination yamitundu yambiri.

Kuwonjezera pa zipangizo, Tonchant imayang'ananso pa kapangidwe kosamalira chilengedwe. Zojambula zochepa, kusindikiza kotsika kwa inki, ndi kapangidwe kotsekanso zimathandiza kukulitsa nthawi ya zinthu ndikuchepetsa kutayika. Zolemba zoyera za chilengedwe zimadziwitsa ogula momwe angatayire phukusi mosamala.

Tonchant imathandiza makampani a khofi kuti agwirizane ndi zomwe ogula amasamala za chilengedwe mwa kuphatikiza kukhazikika kwa zinthu mu gawo lililonse la chitukuko. Kuyambira matumba opangidwa ndi manyowa mpaka matumba a khofi obwezerezedwanso, Tonchant ikutsogolera njira yatsopano yopangira maphukusi a khofi moyenera.

Kodi mwakonzeka kupanga maphukusi anu a khofi kukhala okhazikika? Gwirizanani ndi Tonchant kuti mupange njira zosamalira chilengedwe zomwe zimathandiza mtundu wanu komanso kuteteza dziko lapansi.
