Pamene kayendetsedwe kadziko kakukhazikika kokulirakulira, ogula ambiri ndi mabizinesi akutembenukira ku mayankho ophatikizika a biodegradable. Pakati pawo, mafilimu omwe amatha kuwonongeka ndi chilengedwe amalimbikitsidwa kwambiri ngati njira zokomera zachilengedwe m'malo mwa mapulasitiki wamba. Koma vuto ndi ili: si makanema onse owonongeka omwe amatha kupangidwanso - ndipo kusiyana kwake ndi kopitilira semantics. Kumvetsetsa zomwe zimapanga filimukwenikweni kompositindizofunikira ngati mumasamala za dziko lapansi komanso kutsata.
Ndiye, mungadziwe bwanji ngati filimu yanu yonyamula katundu idzabwereranso ku chilengedwe kapena kukhala m'malo otayirako? Yankho lagona pa certification.
Biodegradable vs. Compostable: Kodi Kusiyana Kweniyeni Ndi Chiyani?
Filimu Yowonongeka Kwambiri
Kanema wa biodegradables, ndiChithunzi cha PLA, amapangidwa kuchokera ku zinthu zomwe zingathe kuphwanyidwa ndi tizilombo toyambitsa matenda monga mabakiteriya kapena bowa. Komabe, izi zingatenge zaka zambiri ndipo zingafune malo enaake monga kutentha, chinyezi, kapena mpweya. Choipa kwambiri, mafilimu ena otchedwa biodegradable films amasanduka ma microplastics - osati kwenikweni zachilengedwe.
Compostable Film
Mafilimu opangidwa ndi kompositi amapita patsogolo. Sikuti zimangowonongeka koma ziyenera kutero pansi pamikhalidwe ya kompositi mkati mwa nthawi yeniyeni, nthawi zambiri masiku 90 mpaka 180. Chofunika kwambiri, ayenera kuchokapalibe poizoni zotsalirandi kupanga madzi okha, carbon dioxide, ndi biomass.
Pali mitundu iwiri ikuluikulu:
-
Mafilimu opangidwa ndi kompositi: Amafuna kutentha kwambiri, malo olamulidwa.
-
Mafilimu opangidwa ndi kompositi kunyumba: Gwirani m'mabini a kompositi kuseri kwa malo otentha, mongafilimu ya celllophane.
Chifukwa Chiyani Ma Certification Ndi Ofunika?
Aliyense akhoza kumenya "eco-friendly" kapena "biodegradable" pa chizindikiro cha mankhwala. Ndi chifukwa chachitatuzizindikiro za compostabilityndizofunika kwambiri - zimatsimikizira kuti chinthucho chikukwaniritsa miyezo yolimba yachitetezo cha chilengedwe ndi magwiridwe antchito.
Popanda chiphaso, palibe chitsimikizo kuti filimu ipanga kompositi monga momwe analonjezera. Choyipa chachikulu, zinthu zosatsimikizika zimatha kuyipitsa malo opangira manyowa kapena kusokeretsa ogula omwe amasamala zachilengedwe.
Satifiketi Yodalirika ya Compostability Padziko Lonse Lapansi
-
✅ASTM D6400/D6868 (USA)
Bungwe Lolamulira:American Society for Testing and Equipment (ASTM)
Ikukhudza:Zopangira ndi zokutira zopangidwirakompositi ya mafakitale(malo otentha kwambiri)
Zida Zovomerezeka:
-
Mafilimu a PLAs (Polylactic Acid)
-
PBS (Polybutylene Succinate)
-
Zosakaniza zochokera ku starch
Zofunika Zoyeserera:
-
Kupatukana:90% ya zinthuzo ziyenera kugawikana kukhala tinthu ting'onoting'ono <2mm mkati mwa milungu 12 mu kompositi yamakampani (≥58°C).
-
Biodegradation:90% kutembenuka kukhala CO₂ mkati mwa masiku 180.
-
Eco-toxicity:Kompositi sayenera kulepheretsa kukula kwa mbewu kapena nthaka yabwino.
-
Heavy Metal Test:Milingo ya lead, cadmium, ndi zitsulo zina ziyenera kukhalabe m'malire otetezeka.
-
✅EN 13432 (Europe)
Bungwe Lolamulira:European Committee for Standardization (CEN)
Ikukhudza:Zopangira zopangira kompositi zamakampani
Zida Zovomerezeka:
- Mafilimu a PLA
- Cellophane (ndi zokutira zachilengedwe)
- PHA (Polyhydroxyalkanoates)
Zofunika Zoyeserera:
-
Chemical Makhalidwe:Imayezera zolimba zosakhazikika, zitsulo zolemera, zomwe zili ndi fluorine.
-
Kupatukana:Zotsalira zosakwana 10% pakadutsa milungu 12 pamalo opangira manyowa.
-
Biodegradation:Kuwonongeka kwa 90% kukhala CO₂ mkati mwa miyezi 6.
-
Ecotoxicity:Imayesa kompositi pa kameredwe ka mbeu ndi kumera kwa mbeu.
- ✅Kompositi OK / OK Kompositi HOME (TÜV Austria)
Ma certification awa amawonedwa kwambiri ku EU ndi kupitirira apo.
OK Kompositi: Imagwira ntchito pa kompositi ya mafakitale.
OK Kompositi HOME: Imagwira ntchito yotsika kutentha, kompositi yapakhomo - kusiyana kosowa komanso kofunikira kwambiri.
- ✅BPI Certification (Biodegradable Products Institute, USA)
Chimodzi mwazinthu zodziwika bwino ku North America. Imamanga pamiyezo ya ASTM ndipo imaphatikizanso njira yowunikiranso kuti zitsimikizire kuti zili bwino.
Lingaliro Lomaliza: Chitsimikizo Sichosankha - Ndikofunikira
Ziribe kanthu momwe filimuyo imadzinenera kukhala yosasinthika, popandasatifiketi yoyenera, ndi malonda chabe. Ngati ndinu mtundu wopangira ma compostable - makamaka chakudya, zopanga, kapena zogulitsa - kusankha mafilimuzotsimikiziridwa ndi malo omwe akufuna(kompositi yamakampani kapena yakunyumba) imatsimikizira kutsata malamulo, kukhulupirira kwamakasitomala, komanso kukhudzidwa kwenikweni kwa chilengedwe.
Mukufuna thandizo lozindikira ogulitsa mafilimu ovomerezeka a PLA kapena cellophane? Nditha kukuthandizani pakufufuza kapena kufananitsa ndiukadaulo - ingondidziwitsani!
