Ma waho aʻe o PVC, hana mākou i nā kāleka i ka polycarbonate (PC) a me ka Polyethylene Terephthalate Glycol (PETG). ʻO kēia mau mea plastic ʻelua e hana i nā kāleka kūʻokoʻa i ka wela.

No laila, he aha ka PETG a no ke aha ʻoe e noʻonoʻo ai no kāu kāleka plastik? ʻO ka mea hoihoi, hana ʻia ʻo PETG mai ka polyester (e pololei, thermoplastic coplyester) ʻaʻole PVC, a he 100 pakeneka hiki ke hana hou ʻia a hiki ke biodegradable. Eia nō naʻe, hana like ia e like me PVC, no laila paʻakikī a pale i ka hopena. He maʻalahi ka paʻi ʻana me PETG a maikaʻi nā hoʻolālā! E nānā i ka nani o nā hoʻolālā ma PETG.

No laila, kūpono nā kāleka PC a me PETG no ka ʻāina wela, no ka laʻana ʻo United Arab Emirates a i ʻole ʻAmelika Hema, kahi e piʻi ai ka mahana i ke kauwela i 40 degere Celsius, a i ʻole 65 degere Celsius i loko o nā kaʻa. Hoʻomaka ka hoʻoheheʻe ʻana o PVC ma 60 degere.

ʻO kā mākou mau kāleka PC a me PETG ka wela a hiki i 120 degere Celsius. ʻO ia hoʻi, i kekahi mau kūlana ʻino loa, hiki ke waiho ʻia kahi kāleka ID kūhelu i loko o ke kaʻa i ka wā hoʻomaha ʻaina awakea me ka hopohopo ʻole no ia mea, a ʻaʻole pono e hoʻokaʻawale ʻia kahi mīkini kāleka ma kahi kaʻa kaʻa ma Toronto a hiki i ka ahiahi. He paʻakikī loa kēia mau kāleka, no laila hiki ke hoʻohana ʻia a hiki i ka ʻumi makahiki.

E hana mākou i ka mea maikaʻi loa e hoʻomau i ka hoʻokō ʻana i nā pono o kā mākou mea kūʻai aku ma o ka hoʻomau ʻana i ka hoʻomohala, hana a hoʻolako i nā huahana hou a kiʻekiʻe.a
