E loaʻa iā UK ke kūlana mua loa no ka plastic biodegradable ma hope o ka huikau ma luna o ka terminology

Pono e hoʻokaʻawale ʻia ʻo Plasic i loko o nā mea organik a me carbon dioxide ma ka lewa ākea i loko o ʻelua mau makahiki e helu ʻia he biodegradable ma lalo o kahi kūlana UK hou i hoʻolauna ʻia e ka British Standards Institute.
He kanaiwa pākēneka o ke kalapona organik i loko o ka plastic e pono e hoʻololi i carbon dioxide i loko o 730 mau lā no ka hoʻokō ʻana i ka maʻamau BSI hou, i hoʻokomo ʻia ma hope o ka huikau i ke ʻano o ka biodegradability.
Hoʻopili ʻia ka maʻamau PAS 9017 i nā polyolefins, kahi ʻohana thermoplastics e komo pū ana me ka polyethylene a me ka polypropylene, nona ke kuleana no ka hapalua o nā haumia plastik āpau i ke kaiapuni.
Hoʻohana nui ʻia nā polyolefins e hana i nā ʻeke lawe, nā huaʻai a me nā mea ʻai meaʻai a me nā hue inu.
"ʻO ka hoʻopaʻapaʻa ʻana i ka paʻakikī honua o ka ʻōpala plastik e pono ai ka noʻonoʻo a me ka hana hou," wahi a Scott Steedman, ka luna o nā kūlana ma BSI.
"Pono nā manaʻo hou e ʻae ʻia, loaʻa i ka lehulehu, nā kūlana kūʻokoʻa e hiki ai i ka hāʻawi ʻana i nā hopena hilinaʻi e ka ʻoihana," i hoʻohui ai ʻo ia, e wehewehe ana i ka maʻamau hou ʻo "ka manaʻo mua o ka poʻe kuleana e pili ana i ke ana ʻana i ka biodegradability o polyolefins e wikiwiki ai ka hōʻoia ʻana o nā ʻenehana. no ka biodegradation plastic.
E pili wale nō ke kūlana i ka pollution plastic ma ka ʻāina
ʻO PAS 9017, i kapa ʻia ʻo Biodegradation of polyolefins i loko o kahi kaiapuni honua ākea, pili i ka hoʻāʻo ʻana i ka plastic e hōʻoia i hiki ke wāwahi i loko o kahi wax pōʻino ʻole i ka lewa.
Hoʻopili wale ka maʻamau i ka pollution plastic ma ka ʻāina, e like me ka BSI, e hana i ʻekolu hapaha o ka plastik mahuka.
ʻAʻole ia e uhi i ka plastik i loko o ke kai, kahi i ʻike ai nā mea noiʻi e hoʻohana mau ʻia nā ʻeke plastik biodegradable ma hope o ʻekolu makahiki.
"E manaʻo ʻia ka hōʻike hoʻāʻo inā he 90 pākēneka a ʻoi aku paha o ke kalapona organik i loko o ka wax e hoʻololi ʻia i carbon dioxide ma ka hopena o ka manawa hoʻāʻo ke hoʻohālikelike ʻia i ka mana maikaʻi a i ʻole ma ka ʻoiaʻiʻo," wahi a ka BSI.
"ʻO ka nui o ka manawa no ka manawa hoʻāʻo he 730 mau lā."
Hana ʻia ka maʻamau e kāpae i nā mea hana e alakaʻi hewa i ka lehulehu
I ka makahiki i hala aku nei, ma waena o nā hopohopo e alakaʻi hewa ana nā mea hana i ka lehulehu i ka wā e hoʻohana ai i nā huaʻōlelo e like me "biodegradable", "bioplastic" a me "compostable", ua kāhea ke aupuni UK i nā poʻe loea e kōkua iā ia e hoʻomohala i nā kūlana no nā plastics.
ʻO ka huaʻōlelo "biodegradable" e hōʻike ana e wāwahi ʻole kahi mea i loko o ke kaiapuni, ʻoiai hiki ke lawe i nā haneli mau makahiki no kekahi mau plastics e hana pēlā.

Ke neʻe nei ke aupuni o UK e hoʻopau i ka huaʻōlelo bioplastic "ʻāhewa a hoʻopunipuni".

ʻO Bioplastic, ʻo ia ka plastic i hana ʻia mai nā mea i loaʻa mai nā mea kanu ola a i ʻole nā ​​​​holoholona, ​​ʻaʻole hiki ke biodegradable. E wāwahi wale ʻia ka plastic compostable inā hoʻokomo ʻia i loko o kahi puʻupuʻu kūikawā.
Hoʻokumu ʻia ʻo PAS 9017 me kahi hui hoʻokele o nā loea plastics a kākoʻo ʻia e Polymateria, kahi hui Pelekane i hoʻomohala i kahi mea hoʻohui e hiki ai i nā plastics fossil-fuel ke biodegrade.
ʻO ke kaʻina hana hou i hoʻolālā ʻia e ʻae i nā plastics e biodegrade
Hiki i ka mea hoʻohui ke hiki i nā thermoplastics, ka mea kūpaʻa loa i ka hoʻohaʻahaʻa ʻana, e wāwahi ma hope o kahi papa i hāʻawi ʻia i ka wā e ʻike ʻia ai i ka ea, ka māmā a me ka wai me ka ʻole o ka hana ʻana i nā microplastics hiki ke pōʻino.
ʻO ke kaʻina hana naʻe e hoʻololi i ka hapa nui o ka plastic i carbon dioxide, ʻo ia ke kinoea ʻōmaʻomaʻo.
"Ua hoʻolālā ʻia kā mākou ʻenehana e loaʻa i nā mea hoʻoulu he nui e hōʻoia i ka hoʻōla ʻana ma mua o hoʻokahi wale nō," wahi a Polymateria.
"Pēlā manawa, ʻo ke kukui UV, ka mahana, ka haʻahaʻa a me ka ea e pāʻani i nā ʻano like ʻole e komo me ka ʻenehana e hoʻololi i ka plastic i kahi mea biocompatible."
"Ua hōʻike ʻia nā hoʻokolohua kūʻokoʻa kūʻokoʻa ʻekolu ʻaoʻao e loaʻa iā mākou ka 100 pākēneka biodegradation ma kahi pahu plastik paʻa i nā lā 336 a me nā mea kiʻiʻoniʻoni ma 226 mau lā i nā kūlana honua maoli, e waiho ana i nā microplastics ʻole ma hope a i ʻole e hoʻopilikia i ke kaiapuni i ke kaʻina hana," Polymateria Ua haʻi aku ʻo CEO Niall Dunne iā Dezeen.

"ʻAʻole e hana pū ka ʻoihana pōʻai me nā mea i loaʻa iā mākou" wahi a Cyrill Gutsch o Parley no ka Moana.

Me ka hana ʻana i ka plastic i manaʻo ʻia e pālua ʻia e 2050, nui nā mea hoʻolālā e ʻimi nei i nā mea ʻē aʻe i nā plastics-based fossil.
Ua hana hou ʻo Priestman Goode i ka ʻeke meaʻai wikiwiki hiki ke hoʻohana hou ʻia mai nā pūpū koko, ʻoiai ʻo Bottega Veneta i hana i kahi kāmaʻa biodegradable i hana ʻia mai ke kō a me ke kofe.
Ua lanakila ʻo James Dyson Award i kēia makahiki ma UK e kahi hoʻolālā e hopu ana i nā microplastic emissions mai nā huila kaʻa, ʻo ia kekahi o nā kumu nui o ka pollution plastic.
