I ngā tau tata nei, kua haere tonu te whakawhānui ake o te umanga polypropylene i tōna kaha, ā, kua tipu haere hoki tōna turanga whakaputa; Heoi, nā te puhoi o te tipu o te tono i raro iho me ētahi atu āhuatanga, he nui te pēhanga kei te taha tuku o te polypropylene, ā, e kitea ana te whakataetae i roto i te umanga. He maha ngā wā ka whakaitihia e ngā umanga ā-rohe te whakaputa me te kati i ngā mahi, ka hua ake te hekenga o te kawenga whakahaere me te hekenga o te whakamahinga o te kaha whakaputa polypropylene. E matapaetia ana ka pakaru te reiti whakamahinga o te kaha whakaputa polypropylene i te iti rawa o mua i te tau 2027, engari he uaua tonu te whakaiti i te pēhanga tuku.
Mai i te tau 2014 ki te tau 2023, kua tino piki ake te kaha whakaputa polypropylene ā-rohe, ā, koinei te take i piki ake ai te hanga polypropylene ā-tau. I te tau 2023, kua eke te tere tipu matū ki te 10.35%, ā, i te tau 2021, kua eke te tere tipu hanga polypropylene ki tētahi taumata teitei hou i roto i te tata ki te 10 tau. Mai i te tirohanga whanaketanga ahumahi, mai i te tau 2014, nā ngā kaupapa here matū waro i akiaki, kua piki haere tonu te kaha whakaputa waro ki ngā polyolefin, ā, kua piki haere te hanga polypropylene ā-rohe i ia tau. I te tau 2023, kua eke te hanga polypropylene ā-rohe ki te 32.34 miriona tana.
I ngā rā kei te heke mai, ka tukuna tonutia he kaha whakaputa hou mō te polypropylene ā-rohe, ā, ka piki ake anō hoki te whakaputanga. E ai ki te whakatau tata a Jin Lianchuang, ko te tere tipu o te whakaputanga polypropylene ia marama i te tau 2025 he tata ki te 15%. E matapaetia ana i te tau 2027, ka eke te whakaputanga polypropylene ā-rohe ki te tata ki te 46.66 miriona tana. Heoi, mai i te tau 2025 ki te 2027, kua puhoi haere te tere tipu o te whakaputanga polypropylene i ia tau. I tetahi taha, he maha ngā whakaroa i roto i ngā taputapu whakawhānui kaha, ā, i tetahi atu taha, i te mea ka nui haere te pēhanga tuku me te piki haere o te whakataetae whānui i roto i te umanga, ka whakaitihia e ngā umanga ngā mahi kino, ka whakanuia rānei te wāhi waka hei whakaiti i te pēhanga wā poto. I taua wā anō, e whakaata ana hoki tēnei i te āhua o nāianei o te puhoi o te tono mākete me te tere o te tipu kaha.
Mai i te tirohanga o te whakamahinga o te kaha, i roto i te horopaki o te hua pai whānui, he nui te reiti whakamahinga o te kaha o ngā umanga whakaputa mai i te tau 2014 ki te 2021, me te reiti whakamahinga o te kaha taketake neke atu i te 84%, inā koa ka eke ki te tihi o te 87.65% i te tau 2021. Whai muri i te tau 2021, i raro i te pēhanga takirua o te utu me te tono, kua heke te reiti whakamahinga o te kaha whakaputa polypropylene, ā, i te tau 2023, kua heke te reiti whakamahinga o te kaha whakaputa ki te 81%. I te wāhanga whakamutunga, he maha ngā kaupapa polypropylene ā-rohe e whakamaheretia ana kia whakahaerehia, nō reira ka pehia te mākete e te nui o te tuku me ngā utu nui. Hei tāpiri, kei te puta haere ngā uauatanga o te korenga o ngā ota o muri, te kohinga o ngā hua kua oti, me te hekenga o ngā hua o te polypropylene. Nō reira, ka whai wāhi hoki ngā umanga whakaputa ki te whakaiti i te kawenga, ki te whai wāhi rānei ki te kati mō te tiaki. Mai i te tirohanga o te waro ki te polypropylene, i tēnei wā, ko te nuinga o ngā hua waro ki te polypropylene o Haina he rauemi whānui iti te mutunga me ētahi rauemi motuhake waenga-rahi, me ētahi hua utu nui e kawemai ana. Me haere tonu te panoni me te whakapai ake i ngā pakihi, me te neke haere mai i ngā hua iti te utu me ngā hua iti te uara tāpiri ki ngā hua nui te utu, kia pai ai te whakataetae i te mākete.
