He aha ka ʻeke biodegradable

1. ʻEke palaho bio，ʻO nā ʻeke palaho bio nā ʻeke i hiki ke palaho ʻia e ka bacteria a i ʻole nā ​​​​olaola ʻē aʻe. Ma kahi o 500 biliona a 1 trillion mau ʻeke palaki i hoʻohana ʻia i kēlā me kēia makahiki. ʻO nā ʻeke palaho bio nā ʻeke i hiki ke palaho ʻia e ka bacteria a i ʻole nā ​​​​olaola ʻē aʻe. Ma kahi o 500 biliona a 1 trillion mau ʻeke palaki i hoʻohana ʻia i kēlā me kēia makahiki.
2. E hoʻokaʻawale ma waena o ka "biodegradable" a me ka "compostable"
Ma nā huaʻōlelo maʻamau, ʻokoʻa ke ʻano o ka huaʻōlelo biodegradable ma mua o ka compost. ʻO ke ʻano o ka Biodegradable hiki ke hoʻopau ʻia nā mea e nā bacteria a i ʻole nā ​​​​olaola ʻē aʻe, a ʻo ka "compost" i ka ʻoihana plastic ua wehewehe ʻia ʻo ia ka hiki ke decompose i kahi ʻano aerobic i mālama ʻia ma nā kūlana mahana a me ka haʻahaʻa i kāohi ʻia. ʻO ka Compospost ka hiki ke biodecompose i loko o kahi kahua compost, e hana ana i nā mea i ʻike ʻole ʻia a decomposed i loko o ke kalapona dioxide, ka wai, nā hui inorganic a me ka biomass ma ka wikiwiki e kūlike me

ʻO ka hoʻokomo ʻia ʻana o ka "mea inorganic" i kāpae i ka huahana hope loa mai ka manaʻo ʻia he compost a humus paha, ʻo ia hoʻi he mea organik wale nō. ʻO ka ʻoiaʻiʻo, ʻo ke kūlana xxx i koi ʻia no ka plastic e kapa ʻia he compost ma lalo o ka wehewehe ʻana o ASTM ʻo ia ka mea e nalo ai i ka like me kahi mea ʻē aʻe i ʻike mua ʻia e 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 hoʻoulu ai i ka polymer (polyethylene) degradation a laila biodegradable ma muli o.
3. Mea hana no ka ʻeke biodegradable
ikaika a hilinaʻi hoʻi e like me nā ʻeke kuʻuna (ʻo ka polyethylene nui). Hana ʻia nā ʻeke he nui me ka pepa, nā mea organik, a i ʻole polyhexanolactone. "ʻIke ka lehulehu he mea kilokilo ka biodegradable," ʻoiai ua hoʻohana nui ʻia ka huaʻōlelo, e like me RamaniNarayan, he ʻenekinia kemika ma ke Kulanui ʻo East Lansing Michigan State a he kākāʻōlelo ʻepekema ma ka Institute for Biodegradable Plastics." ʻO kēia ka huaʻōlelo i hoʻohana pinepine ʻia a hoʻohana hewa ʻia i loko o kā mākou puke wehewehe ʻōlelo. Ma ka Greater Pacific Waste Area, wāwahi ka plastic biodegradable i nā ʻāpana liʻiliʻi e hiki ke komo maʻalahi i ke kaulahao meaʻai ma o ka ʻai ʻia ʻana.
4. Hana hou ʻana o nā ʻeke biodegradable.
Hiki ke hana hou ʻia nā ʻōpala i loko o nā mea kanu, akā he paʻakikī ke hoʻokaʻawale a hana hou ma hope o ka ʻai ʻana. Hiki i nā polymers bio-based ke hoʻohaumia i ka hana hou ʻana o nā polymers maʻamau ʻē aʻe. ʻOiai ʻo nā mea hana o nā plastics biodegradable aerobic e ʻōlelo nei he hiki ke hana hou ʻia kā lākou mau ʻeke, ʻaʻole e ʻae ka nui o nā mea hana hana kiʻiʻoniʻoni plastik iā lākou no ka mea ʻaʻohe noiʻi lōʻihi e pili ana i ka hiki ke hana hou ʻia nā huahana i loaʻa kēia mau mea hoʻohui. Eia kekahi, ua ʻōlelo ka Institute for Biodegradable Plastics (BPI) ʻokoʻa loa nā ʻano o nā mea hoʻohui i nā kiʻiʻoniʻoni oxidized, kahi e hoʻolauna ai i ka ʻokoʻa hou aʻe i ke kaʻina hana hana hou.
