ʻO ka mana kiʻekiʻe a me ka hana hou ʻana o PVC e hōʻike ana e hoʻomaka nā halemai me ka PVC no nā papahana hoʻomaʻamaʻa lāʻau lapaʻau. Ma kahi o 30% o nā lāʻau lapaʻau plastik i hana ʻia me ka PVC, ka mea i hana i kēia mea i ka polymer maʻamau i hoʻohana ʻia no ka hana ʻana i nā ʻeke, nā paipu, nā masks a me nā mea lapaʻau ʻē aʻe.
Hoʻokaʻawale ʻia ka ʻāpana i koe ma waena o 10 polymers like ʻole. ʻO kēia kekahi o nā ʻike nui o kahi noiʻi mākeke hou i mālama ʻia e kahi ʻoihana noiʻi mākeke honua a me ka hui kūkākūkā hoʻokele. Wahi a ka haʻawina e mālama ʻo PVC i kāna kūlana helu ʻekahi a hiki i ka liʻiliʻi o 2027.
He maʻalahi ka PVC a he nui nā mea hoʻohana. Hiki ke hana ʻia nā ʻāpana palupalu a ʻoʻoleʻa i hoʻokahi polymer-ʻo ia ke kī i ka kūleʻa o ka hana hou ʻana i ka plastic. Hōʻike ka mana kiʻekiʻe a me ka recyclability kūʻokoʻa o ka PVC e hoʻomaka nā halemai me kēia mea palaka i ka wā e noʻonoʻo ai i nā hoʻolālā hana hou no ka ʻōpala plastik olakino.
Ua ʻōlelo nā limahana pili i nā ʻike hou: "Ua hōʻike ka maʻi maʻi i ke kuleana nui i hoʻokani ʻia e nā mea lapaʻau plastic disposable i ka pale ʻana a me ka hoʻopaʻa ʻana i nā maʻi o ka haukapila. ʻO ka hopena maikaʻi ʻole o kēia kūleʻa ʻo ia ka piʻi ʻana o ka nui o nā ʻōpala palaka halemai. Manaʻo mākou ʻo ka hana hou ʻana he ʻāpana o ka hopena.
I kēia manawa, ʻo ka loaʻa ʻana o nā mea CMR (carcinogenic, mutagenic, reproductive toxicity) i loko o kekahi mau lako PVC he mea keakea ia i ka hana hou PVC olakino. Ua ʻōlelo ʻia ua hoʻoholo ʻia kēia pilikia: "No ka mea kokoke i nā noi āpau, loaʻa a hoʻohana ʻia nā plasticizers ʻē aʻe no PVC. ʻEhā o lākou i kēia manawa i helu ʻia i ka European Pharmacopoeia, kahi huahana lapaʻau ma ʻEulopa a me nā wahi ʻē aʻe.
