He aha ka ʻeke biodegradable

1. ʻeke Biodegradation ， ʻO nā ʻeke Biodegradation he mau ʻeke hiki ke hoʻoheheʻe ʻia e ka bacteria a i ʻole nā ​​mea ola ʻē aʻe. Ma kahi o 500 biliona a 1 trillion ʻeke plastik e hoʻohana ʻia i kēlā me kēia makahiki. ʻO nā ʻeke biodegradation nā ʻeke hiki ke hoʻoheheʻe ʻia e ka bacteria a i ʻole nā ​​​​mea ola ʻē aʻe. Ma kahi o 500 biliona a 1 trillion ʻeke plastik i hoʻohana ʻia i kēlā me kēia makahiki.
2. Hoʻokaʻawale ma waena o "biodegradable" a me "compostable"
Ma nā huaʻōlelo maʻamau, ʻokoʻa ke ʻano o ka huaʻōlelo biodegradable ma mua o ka compost. Biodegradable ʻo ia ka mea hiki ke decomposed nā mea e ka bacteria a i ʻole nā ​​mea ola ʻē aʻe, a ʻo ka "compost" i loko o ka ʻoihana plastik ua wehewehe ʻia ʻo ia ka hiki ke decompose i loko o kahi ʻano aerobic i mālama ʻia ma kahi kikoʻī. ʻO nā kūlana o ka mahana a me ka haʻahaʻa.

ʻO ka hoʻokomo ʻia ʻana o nā "mea inorganic" i kāpae ʻia i ka huahana hope mai ka manaʻo ʻia he compost a humus paha, ʻo ia ka mea maʻemaʻe maoli. e helu ʻia ma ke ʻano he mea ʻē aʻe i ʻike mua ʻia i ka compost ma lalo o ka wehewehe kuʻuna. Hiki ke hana ʻia nā ʻeke plastik mai kahi polymer plastik maʻamau (ʻo ia hoʻi, polyethylene) a i ʻole polypropylene a hui pū ʻia me kahi mea hoʻohui e hōʻemi ai i ka polymer (polyethylene) a laila biodegradable ma muli o.
3.Material no ka ʻeke biodegradable
ikaika e like me ka paʻa a me ka hilinaʻi e like me nā ʻeke kahiko (ka nui polyethylene). "Ua ʻike ka lehulehu i ka biodegradable he mea kupua," ʻoiai ua hoʻohana nui ʻia ka huaʻōlelo, e like me ka ʻōlelo a RamaniNarayan, he ʻenekinia kemika ma East Lansing Michigan State University a he loea ʻepekema ma ka Institute for Biodegradable Plastics." a hoʻohana hewa ʻia ka huaʻōlelo ma kā mākou puke wehewehe ʻōlelo. Ma ka Greater Pacific Waste Area, wāwahi ʻia ka plastic biodegradable i mau ʻāpana liʻiliʻi i hiki ke maʻalahi ke komo i ke kaulahao meaʻai ma ka ʻai ʻana.
4. Ka hana hou ʻana i nā ʻeke biodegradable.
Hiki ke hana hou i ka ʻōpala i loko o ka mea kanu, akā paʻakikī ke ʻano a hana hou ʻia ma hope o ka ʻai ʻana. Hiki i nā polymers kumu bio ke hoʻohaumia i ka hana hou ʻana o nā polymers maʻamau. ʻAʻole e ʻae nā mea hana hou iā lākou no ka mea ʻaʻohe aʻo lōʻihi e pili ana i ka hiki o nā huahana recyclable i loaʻa i kēia mau mea hoʻohui. i ke kaʻina hana hou.
