Biodegradable a me ka compostable

Wehewehe a me ka hoohana hewa

Hoʻohana pinepine ʻia ka biodegradable a me ka compostable e wehewehe i ka haki ʻana o nā mea kūlohelohe i nā kūlana kikoʻī. Eia naʻe, ʻo ka hoʻohana hewa ʻana i ka "biodegradable" i ke kūʻai aku ua alakaʻi i ka huikau i waena o nā mea kūʻai. No ka hoʻoponopono ʻana i kēia, hoʻohana nui ʻo BioBag i ka huaʻōlelo "compostable" no kā mākou huahana i hōʻoia ʻia.

Hiki i ka biodegradability

ʻO ka biodegradability e pili ana i ka hiki o kahi mea ke hana i ka hoʻohaʻahaʻa olaola, e hana ana i CO₂, H₂ʻO, methane, biomass, a me nā paʻakai mineral. ʻO nā microorganisms, hānai nui ʻia e ka ʻōpala organik, hoʻokele i kēia kaʻina hana. Eia nō naʻe, ʻaʻohe kikoʻī o ka huaʻōlelo, no ka mea, e hoʻoheheʻe ʻia nā mea a pau, e hōʻike ana i ka pono e wehewehe i ke kaiapuni i manaʻo ʻia no ka biodegradation.

Hoʻopuehu

Hoʻopili ka compost i ka hoʻoheheʻe ʻana i ka microbial e wāwahi i ka ʻōpala organik i loko o ka compost, pono no ka hoʻonui ʻana i ka lepo a me ka fertilization. Pono ka pae wela, ka wai, a me ka oxygen no kēia kaʻina hana. I loko o nā puʻu o nā ʻōpala organik, ʻai nā microbes he nui i nā mea, hoʻololi iā lākou i compost. Pono ka compostability piha i ka pili ʻana i nā kūlana koʻikoʻi e like me European Norm EN 13432 a me US Standard ASTM D6400, e hōʻoiaʻiʻo ana i ka decomposition piha me nā koena pōʻino.

Nā Kūlana Kūikawā

Ma waho aʻe o ka European Standard EN 13432, loaʻa i nā ʻāina like ʻole kā lākou mau maʻamau, me ka US Standard ASTM D6400 a me Australian norm AS4736. ʻO kēia mau maʻamau ka mea i hōʻike ʻia no nā mea hana, nā kino hoʻoponopono, nā mea hana compost, nā ʻoihana hōʻoia, a me nā mea kūʻai aku.

Nā Koina no nā Mea Pahu

Wahi a ka European Standard EN 13432, pono e hōʻike nā mea compostable:

• ʻO ka biodegradability o ka liʻiliʻi he 90%, e hoʻololi ana i CO₂i loko o ʻeono mahina.
• Hoʻokaʻawale ʻia, ka hopena ma lalo o 10% koena.
• Ka launa pū me ke kaʻina hana compost.
• Haʻahaʻa haʻahaʻa o nā metala koʻikoʻi, me ka ʻole e hōʻemi i ka maikaʻi o ka compost.

Ka hopena

ʻAʻole hiki i ka biodegradability wale nō ke hōʻoia i ka compostability; pono hoʻi e hoʻoheheʻe ʻia nā mea waiwai i loko o hoʻokahi pōʻaiapili compost. ʻO ka mea ʻē aʻe, ʻaʻole manaʻo ʻia nā mea i ʻāpana i nā ʻāpana micro-biodegradable i hoʻokahi pōʻai. Hōʻike ʻo EN 13432 i kahi maʻamau ʻenehana i hoʻohālikelike ʻia me ka European Directive 94/62/EC e pili ana i ka ʻōpala a me nā ʻōpala.
