Compostable vs. Biodegradable: Kumvetsetsa Kusiyanitsa

M'dziko lamasiku ano lokonda zachilengedwe, ogula akufunafuna njira zodalirika zogulira tsiku ndi tsiku. Mawu ngati "compostable" ndi "biodegradable" nthawi zambiri amagwiritsidwa ntchito mosiyana, koma pali kusiyana kwakukulu pakati pa ziwirizi. Kumvetsetsa kusiyanaku kumakupatsani mphamvu kuti mupange zisankho zomwe zikugwirizana ndi zolinga zanu zokomera chilengedwe.

Zowonongeka Zowonongeka: Tanthauzo Lalikulu

Biodegradability imatanthawuza kuthekera kwa chinthu kusweka kukhala zinthu zachilengedwe, makamaka zamoyo, kudzera mu zochita za tizilombo. Izi zitha kuchitika m'mikhalidwe yosiyanasiyana, kuphatikizapo zotayiramo, nthaka, kapena madzi.

Ngakhale kuti biodegradability ndi chinthu chabwino, sichimatsimikizira kuwonongeka kwachangu kapena kowononga chilengedwe. Mlingo wa biodegradation ukhoza kusiyana kwambiri kutengera zinthu, chilengedwe, komanso kupezeka kwa tizilombo tating'onoting'ono. Zinthu zina zowola zimatha kutenga zaka kapena makumi kuti ziwole bwino.

Compostable: Mulingo Wapadera

Compostability ndi gawo lolimba kwambiri la biodegradability. Zinthu zopangidwa ndi manyowa zimasanduka zinthu zachilengedwe pakanthawi kochepa, nthawi zambiri mkati mwa miyezi 6 mpaka 12, m'malo opangidwa ndi kompositi. Malowa, omwe amadziwika ndi kutentha kwapadera, chinyezi, ndi mpweya wabwino, amachititsa kuti tizilombo toyambitsa matenda tiwonongeke.

Zogulitsa zopangidwa ndi kompositi zimatsata njira zokhazikika zokhazikitsidwa ndi mabungwe monga Biodegradable Products Institute (BPI) ku United States ndi European Compostable Packaging Association (ECPA) ku Europe. Zitsimikizo izi zimawonetsetsa kuti zinthu zopangidwa ndi kompositi zimakwaniritsa miyezo yeniyeni yogwirira ntchito, kuphatikiza kuwonongeka kwachilengedwe, kusaonongeka, komanso kusakhalapo kwa zotsalira zovulaza.

Ubwino wa Compostable Materials

Zopangira kompositi zimapereka maubwino angapo kuposa zinthu zakale:

・Zinyalala Zocheperako Zotayiramo Zinyalala: Zinthu zopangidwa ndi manyowa zimapatutsa zinyalala m'malo otayiramo, kuchepetsa mtolo wa kasamalidwe ka zinyalala komanso kuchepetsa chiwopsezo cha kuipitsidwa kwa nthaka ndi madzi.

・Kupanga Kompositi Wopatsa Chakudya Chakudya: Zinthu zopangidwa ndi manyowa zimaphwanyidwa kukhala kompositi yokhala ndi michere yambiri, yomwe ingagwiritsidwe ntchito kulimbikitsa thanzi la nthaka, kuthandizira kukula kwa mbewu, ndi kuchepetsa kufunika kwa feteleza wamankhwala.

・Kusunga Zinthu Zopangira manyowa: Zinthu zopangidwa ndi manyowa nthawi zambiri zimagwiritsa ntchito zinthu zongowonjezedwanso, monga zopangira mbewu, kuchepetsa kudalira nkhokwe zamafuta ochepa.

Kupanga Zosankha Zodziwa

・Posankha pakati pa compostable ndi biodegradable mankhwala, ganizirani izi:

・ Mapeto Ogwiritsa Ntchito: Ngati mankhwalawa apangidwa kuti apange kompositi, sankhani zinthu zovomerezeka za kompositi. Zinthu zomwe zimatha kuwonongeka ndi biodegradable sizingawonongeke m'malo onse opanga manyowa.

・ Chitsimikizo: Yang'anani malonda omwe ali ndi ziphaso kuchokera kumabungwe odziwika ngati BPI kapena ECPA. Zitsimikizo izi zimatsimikizira kuti zinthuzo zimakwaniritsa miyezo ya compostability.

・ Kukhudza Kwachilengedwe: Ganizirani momwe chilengedwe chimakhudzira chilengedwe, kuphatikiza kupanga, kugwiritsa ntchito, ndi kutaya kwake. Sankhani mankhwala okhala ndi mapazi ochepa a chilengedwe.

Kulandira Moyo Wokhazikika

Kutengera zinthu zomwe zimawonongeka ndi compostable ndi sitepe lopita ku moyo wokhazikika. Komabe, ndikofunikira kukumbukira kuti zinthuzi si chipolopolo chasiliva choteteza chilengedwe. Kuchepetsa kadyedwe, kugwiritsanso ntchito zinthu ngati kuli kotheka, ndi njira zoyenera zobwezeretsanso zinthu zimakhala zofunika kwambiri pa moyo wokhazikika.

Popanga zisankho mozindikira komanso kutsatira machitidwe okonda zachilengedwe, titha kuthandiza pamodzi kuti dziko lapansi likhale lathanzi kwa ife eni ndi mibadwo yamtsogolo.
