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 plastic i wehewehe ʻia e like me ka hiki ke decompose i loko o kahi ʻano aerobic i mālama ʻia i nā kūlana hoʻomalu a me ka haʻahaʻa. ka wai, nā mea hoʻohuihui inorganic a me ka biomass ma ke ʻano like me

ʻO ka hoʻokomo ʻia ʻana o nā "mea inorganic" i kāpae ʻia ka huahana hope mai ka manaʻo ʻia he compost a humus paha, ʻo ia ka mea kūlohelohe maoli. 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). "Ke ʻike nei 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."
4. Ka hana hou ʻana i nā ʻeke biodegradable.
Hiki ke hana hou i ka ʻōpala i loko o ka mea kanu, akā paʻakikī ka hoʻokaʻawale ʻana a me ka hana hou ʻana ma hope o ka ʻai ʻana. Ua ʻōlelo ʻo Plastics (BPI) he ʻano like ʻole ka hana ʻana o nā mea hoʻohui i nā kiʻiʻoniʻoni oxidized, kahi e hoʻolauna ai i nā ʻano like ʻole i ke kaʻina hana hou.
