ʻO ke kiʻekiʻe o ka mana a me ka hiki ke hana hou ʻia o PVC e hōʻike ana e hoʻomaka nā haukapila me PVC no nā papahana hana hou ʻana i nā mea lapaʻau plastik. Hana ʻia ʻo PVC ma kahi o 30% o nā mea lapaʻau plastik, ʻo ia ka mea e hoʻolilo ai i kēia mea i polymer i hoʻohana pinepine ʻia no ka hana ʻana i nā ʻeke, nā paipu, nā pale maka a me nā mea lapaʻau hoʻolei ʻē aʻe.
Ua māhele ʻia ke koena ma waena o 10 mau polymers like ʻole. ʻO kēia kekahi o nā ʻike nui o kahi noiʻi mākeke hou i mālama ʻia e kahi hui noiʻi mākeke honua a me ka ʻoihana kūkākūkā hoʻokele. Ua wānana pū ka noiʻi e mālama ʻo PVC i kona kūlana helu ʻekahi a hiki i ka liʻiliʻi o 2027.
He maʻalahi ka hana hou ʻana o ka PVC a he nui nā ʻano hoʻohana. Hiki ke hana ʻia nā lako e pono ai nā ʻāpana palupalu a paʻa i hoʻokahi polymer - ʻo ia ke kī i ka holomua o ka hana hou ʻana o ka plastik. ʻO ke kiʻekiʻe o ka mana a me ka hana hou ʻana o PVC e hōʻike ana e hoʻomaka nā haukapila me kēia mea plastik i ka wā e noʻonoʻo ai i nā hoʻolālā hana hou no nā ʻōpala plastik lapaʻau.
Ua ʻōlelo nā limahana pili i nā ʻike hou: "Ua hōʻike ka maʻi ahulau i ke kuleana koʻikoʻi o nā mea lapaʻau plastik hoʻolei ʻia i ka pale ʻana a me ka kaohi ʻana i nā maʻi haukapila. ʻO ka hopena maikaʻi ʻole o kēia holomua ka hoʻonui ʻia ʻana o ka nui o nā ʻōpala plastik haukapila. Manaʻo mākou he ʻāpana o ka hopena ka hana hou ʻana. ʻO ka mea pōmaikaʻi, ʻo ka plastik i hoʻohana nui ʻia i ka mālama ola kino ʻo ia hoʻi ka plastik hiki ke hana hou ʻia, no laila ke koi aku nei mākou i nā haukapila e hoʻomaka e hoʻohana i ka PVC no nā hana hana hou."
A hiki i kēia manawa, ʻo ke ola ʻana o nā mea CMR (carcinogenic, mutagenic, reproductive toxicity) i loko o kekahi mau lako PVC ua lilo ia i mea keakea i ka hana hou ʻana o ka PVC lapaʻau. Ua ʻōlelo ʻia ua hoʻoholo ʻia kēia pilikia i kēia manawa: "No ka aneane o nā noi āpau, loaʻa a hoʻohana ʻia nā plasticizers ʻē aʻe no ka PVC. ʻEhā o lākou i helu ʻia i kēia manawa ma ka European Pharmacopoeia, he huahana lapaʻau ia ma ʻEulopa a me nā wahi ʻē aʻe. Ua hoʻomohala ʻia nā alakaʻi palekana a me ka maikaʻi."
