1. Tirohanga whānui o te mekameka ahumahi:
Ko te ingoa katoa o te waikawa polylactic ko te waikawa polylactic, te waikawa polylactic rānei. He rauemi polyester ngota teitei i whiwhihia mā te whakakotahitanga me te waikawa lactic, te waikawa lactic rānei hei monomer. Nō tētahi rauemi ngota teitei hangai, ā, he āhuatanga o te pūtake koiora me te pirau. I tēnei wā, he kirihou pirau te waikawa polylactic, ā, kua tino pakari te ahumahi, te putanga nui rawa atu, ā, ko te mea tino whānui te whakamahinga i te ao. Ko te tihi o te ahumahi waikawa polylactic ko ngā momo rauemi mata taketake katoa, pērā i te kānga, te tō, te pīti huka, me ētahi atu, ko ngā pito waenga ko te whakarite i te waikawa polylactic, ā, ko te pito iho ko te tono o te waikawa polylactic, tae atu ki ngā rihi tiaki taiao, ngā takai tiaki taiao, me ētahi atu.
2. Ahumahi o runga
I tēnei wā, ko te waikawa miraka te rauemi mata o te umanga waikawa polylactic o te kāinga, ā, ko te waikawa miraka te nuinga o te wā e hangaia ana mai i te kānga, te tō, te pīti huka me ētahi atu hua ahuwhenua. Nō reira, ko te umanga whakato hua e whakahaerehia ana e te kānga ko te umanga whakarunga o te mekameka ahumahi waikawa polylactic. Mai i te tirohanga o te putanga kānga me te rohe whakato o Haina, ka eke te putanga whakato kānga o Haina ki te 272.55 miriona tana i te tau 2021, me te tauine nui, ā, kua pumau te rohe whakato ki te 40-45 miriona heketea mō ngā tau maha. Mai i te tuku kānga mō te wā roa ki Haina, e tika ana kia noho pumau te tuku kānga a muri ake nei.
Mō ētahi atu rauemi mata ka taea te whakamahi hei whakaputa waikawa miraka, pērā i te tō me te pīti huka, ko te tapeke o te whakaputanga a Haina i te tau 2021 he 15.662 miriona tana, he iti iho i tērā i ngā tau o mua, engari kei te taumata noa tonu. Ā, kei te kaha hoki ngā umanga huri noa i te ao ki te tūhura i ngā huarahi hou hei whakarite waikawa miraka, pērā i te whakamahi i te pūtake huka i roto i ngā muka rakau pērā i te kakau witi me te wahie hei whakarite waikawa miraka, te tūhura rānei i te tikanga whakamahi i te methane hei whakaputa waikawa miraka. I te nuinga o te wā, ka pumau te tuku o te ahumahi whakarunga o te waikawa polylactic i te heke mai.
3. Ahumahi waenga-awa
Hei rauemi pirau-kore, ka taea e te waikawa polylactic te kawe i te rauemi mata ki te pūnaha whakaora me te hangarua rauemi, he painga kāore i te rite ki ngā rauemi hinu. Nō reira, kei te piki haere te whakamahinga o te waikawa polylactic i te mākete o te motu. Ko te whakamahinga o te waikawa o te motu i te tau 2021 ko te 48071.9 tana, he pikinga 40% i ia tau.
Nā te iti o te kaha whakaputa o te waikawa polylactic i Haina, he nui ake te nui o te waikawa polylactic kawemai i Haina i te nui o te kaweake. I ngā tau tata nei, kua tere te pikinga o te nui o te waikawa polylactic kawemai nā te hiahia ā-rohe. I te tau 2021, i eke te kawemai o te waikawa polylactic ki te 25294.9 tana. I tino ahu whakamua hoki te kaweake o te waikawa polylactic i te tau 2021, tae atu ki te 6205.5 tana, he pikinga tau-ki-te-tau o te 117%.
Pūrongo e pā ana: pūrongo mō te tātaritanga ia whanaketanga me te matapae tirohanga whanaketanga o te umanga hua waikawa polylactic o Haina mai i te tau 2022 ki te 2028 i whakaputaina e Zhiyan consulting
4. Ahumahi o raro
I roto i ngā mahi whakararo, kua whakamahia te waikawa polylactic ki ngā mara maha me tōna hototahitanga koiora ahurei me tōna pirau. I tēnei wā, kua whānuitia te whakamahinga i roto i ngā takai taumata pā kai, ngā taputapu kai, ngā takai putea kiriata me ētahi atu hua me ngā mara. Hei tauira, ka taea te pirau katoa me te ngaro i muri i te kotinga o ngā hua te kiriata kirihou ahuwhenua i hangaia mai i te waikawa polylactic, e kore e whakaiti i te nui o te wai me te momona o te oneone, engari ka karohia hoki ngā utu mahi me ngā utu whakahaere tāpiri e hiahiatia ana mō te whakaora i te kiriata kirihou, koinei te ia whānui o te whanaketanga o te kiriata kirihou i Haina a meake nei. Ko te rohe e kapi ana i te kiriata kirihou i Haina e tata ana ki te 18000 heketea, ā, ko te whakamahinga o te kiriata kirihou i te tau 2020 e 1357000 tana. Kia taea te rongonui o te kiriata kirihou pirau, he nui te wāhi o te umanga waikawa polylactic mō te whanaketanga a meake nei.
