E ai ki ngā tatauranga i te tau 2020, ko te kaha whakaputa PVC katoa o te ao i eke ki te 62 miriona tana, ā, ko te putanga katoa i eke ki te 54 miriona tana. Ko te whakahekenga katoa o te putanga ko te tikanga kāore i eke te kaha whakaputa ki te 100%. Nā ngā āhuatanga taiao, ngā kaupapa here ā-rohe me ētahi atu āhuatanga, me iti iho te putanga i te kaha whakaputa. Nā te nui o te utu whakaputa o te PVC i Ūropi me Hapani, ko te kaha whakaputa PVC o te ao kei te nuinga o te wā kei te taha rawhiti o Āhia, ā, kei Haina te haurua o te kaha whakaputa PVC o te ao.
E ai ki ngā raraunga hau, i te tau 2020, ko Haina, te Hononga o Amerika me Hapani ngā wāhi hanga PVC nui o te ao, me te kaha whakaputa mō te 42%, 12% me te 4%. I te tau 2020, ko ngā umanga matua e toru o te kaha whakaputa PVC ā-tau o te ao ko Westlake, shintech me FPC. I te tau 2020, ko te kaha whakaputa PVC ā-tau he 3.44 miriona tana, 3.24 miriona tana me te 3.299 miriona tana. Tuarua, ko ngā umanga he kaha whakaputa neke atu i te 2 miriona tana kei roto hoki ko inovyn. Ko te kaha whakaputa katoa o Haina he 25 miriona tana anō, me te putanga o te 21 miriona tana i te tau 2020. Neke atu i te 70 ngā kaihanga PVC i Haina, 80% o ēnei he tikanga konupūmā karawiti me te 20% he tikanga etilena.
Ko te nuinga o ngā tikanga konupūmā kāpira e kohikohia ana ki ngā wāhi whai rawa waro pērā i a Mongolia o Roto me Xinjiang. Kei ngā takutai te wāhi e hangaia ai te tukanga ethylene nā te mea me kawemai ngā rauemi mata VCM, ethylene rānei. Tata ki te haurua o te ao te kaha whakaputa o Haina, ā, me te whānui haere tonu o te mekameka ahumahi o Haina, ka piki haere tonu te kaha whakaputa PVC o te tikanga ethylene, ā, ka heke tonu te wāhi o Haina ki te PVC o te ao.
