Biodegradable ndi Compostable

Tanthauzo ndi Kugwiritsa Ntchito Molakwika

Biodegradable ndi compostable nthawi zambiri amagwiritsidwa ntchito mosinthana kufotokoza kuwonongeka kwa zinthu organic mu mikhalidwe yeniyeni.Komabe, kugwiritsidwa ntchito molakwika kwa "biodegradable" pakutsatsa kwadzetsa chisokonezo pakati pa ogula.Pofuna kuthana ndi izi, BioBag nthawi zambiri amagwiritsa ntchito mawu oti "compostable" pazinthu zathu zovomerezeka.

Biodegradability

Biodegradability imatanthawuza kuthekera kwa chinthu kuti chiwonongeke, kupanga CO₂, H₂O, methane, biomass, ndi mchere wamchere.Tizilombo tating'onoting'ono, timene timadyetsedwa ndi zinyalala, timayendetsa izi.Komabe, mawuwa alibe tsatanetsatane, popeza zinthu zonse pamapeto pake zimawonongeka, kugogomezera kufunikira kofotokozera malo omwe akufuna kuti biodegradation iwonongeke.

Compostability

Kompositi imaphatikizapo kugayidwa kwa tizilombo toyambitsa matenda kuti tiphwanye zinyalala za organic kukhala kompositi, zopindulitsa kulimbikitsa nthaka ndi umuna.Kutentha koyenera, madzi, ndi mpweya ndizofunikira kuti izi zitheke.Mu milu ya zinyalala zachilengedwe, tizilombo tambirimbiri timadya zinthu, kuzisintha kukhala kompositi.Kompositi yathunthu imafuna kutsata miyezo yokhwima monga European Norm EN 13432 ndi US Standard ASTM D6400, kuwonetsetsa kuwola kwathunthu popanda zotsalira zovulaza.

Miyezo Yadziko Lonse

Kupatula European Standard EN 13432, mayiko osiyanasiyana ali ndi zikhalidwe zawo, kuphatikiza US Standard ASTM D6400 ndi Australian AS4736.Miyezo iyi imakhala ngati benchmark kwa opanga, mabungwe owongolera, malo opangira kompositi, mabungwe opereka ziphaso, ndi ogula.

Zofunikira Zopangira Compostable

Malinga ndi European Standard EN 13432, zinthu zopangidwa ndi kompositi ziyenera kuwonetsa:

• Biodegradability osachepera 90%, kusintha kukhala CO₂mkati mwa miyezi isanu ndi umodzi.
• Kuwonongeka, zomwe zimapangitsa kuti pakhale zotsalira zosakwana 10%.
• Kugwirizana ndi ndondomeko ya composting.
• Miyezo yochepa yazitsulo zolemera, popanda kusokoneza khalidwe la kompositi.

Mapeto

Biodegradability palokha sikutanthauza compostability;zinthu ziyeneranso kusweka pakangopita kompositi imodzi.Mosiyana ndi izi, zida zomwe zimagawika kukhala tizidutswa tating'ono tating'ono tomwe titha kuwononga nthawi imodzi sizimaganiziridwa kuti ndi compost.TS EN 13432 imayimira mulingo wogwirizana waukadaulo, wogwirizana ndi European Directive 94/62/EC pakupakira ndi zinyalala.
