He aha tonu ngā rauemi PCR?
1. He aha ngā rauemi PCR?
Ko te rauemi PCR he momo "kirihou hangarua", ko te ingoa katoa ko te rauemi hangarua muri-kaihoko, arā, he rauemi hangarua muri-kaihoko.
He "tino whai hua" ngā rauemi PCR. I te nuinga o te wā, ka taea te huri i ngā kirihou para i puta mai i muri i te tohatoha, te kai me te whakamahinga hei rauemi mata ahumahi tino whai hua mā te hangarua ā-tinana, te hangarua matū rānei, kia tutuki ai te whakaora rauemi me te hangarua.
Hei tauira, ko ngā rauemi hangarua pēnei i te PET, PE, PP, me te HDPE i ahu mai i ngā kirihou para i hangaia mai i ngā pouaka tina e whakamahia whānuitia ana, ngā pounamu hopi horoi makawe, ngā pounamu wai kohuke, ngā oko mīhini horoi, me ētahi atu. I muri i te tukatuka anō, ka taea te whakamahi hei hanga rauemi tākai hou.
I te mea i ahu mai ngā rauemi PCR i ngā rauemi kua oti te hanga, ki te kore e tukatukahia tika, ko rātou tonu te tino pānga tika ki te taiao. Nō reira, ko te PCR tētahi o ngā kirihou hangarua e taunakihia ana e ngā momo waitohu.
2. He aha i tino rongonui ai ngā kirihou PCR?
•(1)Ko te kirihou PCR tētahi o ngā huarahi nui hei whakaiti i te parahanga kirihou, hei tautoko hoki i te "koretake o te waro".
Whai muri i ngā mahi uaua a ngā whakatipuranga maha o ngā tohunga matū me ngā miihini, kua noho ngā kirihou i hangaia mai i te hinu, te waro, me te hau māori hei rauemi tino nui mō te oranga o te tangata nā te mea he mama, he pakari, he ataahua hoki. Heoi, nā te whakamahinga whānui o ngā kirihou kua hua ake te nui o ngā para kirihou. Ko te hangarua-muri-kaihoko (PCR) kirihou kua noho hei huarahi nui ki te whakaiti i te parahanga taiao kirihou me te āwhina i te umanga matū ki te neke ki te "kore waro".
Ka konatunatua ngā pire kirihou hangarua ki te kapia hou hei hanga i ngā momo hua kirihou hou. Ehara i te mea ka whakaitihia noa e tēnei tikanga ngā tukunga hauhā waro, engari ka whakaitihia hoki te whakapaunga pūngao.
•(2)Whakamahia te kirihou PCR hei whakatairanga ake i te hangarua kirihou para.
Ka nui ake te tono mō ngā kamupene e whakamahi ana i ngā kirihou PCR, ka nui ake hoki te hiahia, ā, ka nui ake te hangarua o ngā kirihou para, ā, ka āta whakarerekētia te tauira me ngā mahi pakihi mō te hangarua kirihou para, ko te tikanga ka iti ake ngā kirihou para ka tukuna ki te whenua, ka tahuna, ka rongoatia ki te taiao.
• (3)Te whakatairanga kaupapa here
Kei te tuwhera haere te wāhi kaupapa here mō ngā kirihou PCR.
Hei tauira, me Ūropi te rautaki kirihou a te EU me ngā ture taake kirihou me te tākai i ngā whenua pēnei i a Peretānia me Tiamana. Hei tauira, kua whakaputa te Tari Tāke me te Tari Take Tāke o te UK i tētahi "Taake Tākai Kirihou". Ko te reiti taake mō ngā tākai he iti iho i te 30% te kirihou hangarua he 200 pauna ia tana. Nā te taake me ngā kaupapa here kua whakatuwhera i te wāhi tono mō ngā kirihou PCR.
3. Ko ēhea ngā kamupene nunui o te umanga e whakapiki ana i ā rātou haumitanga ki ngā kirihou PCR i ngā wā tata nei?
I tēnei wā, ko te nuinga o ngā hua kirihou PCR kei te mākete kei te hangarua tonu i runga i te āhua tūturu. Kei te piki haere te maha o ngā ahumahi matū o te ao e whai ana i te whanaketanga me te whakamahinga o ngā hua kirihou PCR hangarua matū. Ko tā rātou e tumanako ana kia rite te mahi a ngā rauemi hangarua ki ngā rauemi mata, ā, ka taea te whakatutuki i te "whakaiti waro".
•(1). BASF'Kua whiwhi te rauemi hangarua Ultramid i te tiwhikete UL
I pānuitia e BASF i tēnei wiki kua whiwhi tiwhikete tana pūhui hangarua Ultramid Ccycled i hangaia i tana wheketere i Freeport, Texas, mai i Underwriters Laboratories (UL).
E ai ki te UL 2809, ka taea e ngā pūmua Ultramid C-cycled te hangarua mai i ngā kirihou hangarua muri-kaihoko (PCR) te whakamahi i tētahi pūnaha taurite papatipu hei whakatutuki i ngā paerewa ihirangi hangarua. He rite tonu ngā āhuatanga o te momo pūmua ki te rauemi mata, ā, kāore e hiahiatia he whakarerekētanga ki ngā tikanga tukatuka tuku iho. Ka taea te whakamahi i roto i ngā tono pēnei i ngā kiriata takai, ngā whāriki me ngā taonga, ā, he huarahi tauwhiro hei whakakapi i ngā rauemi mata.
Kei te rangahau a BASF i ngā tukanga matū hou hei huri tonu i ētahi kirihou para hei rauemi mata hou, whai hua. Mā tēnei huarahi ka whakaitihia ngā tukunga hau kati kōtuhi me ngā whakaurunga rauemi mata pūngāwerewere, me te pupuri tonu i te kounga me te mahi o te hua.
Randall Hulvey, Kaiwhakahaere Pakihi BASF o Amerika Te Raki:
"He rite tonu te kaha ā-mīhini, te pakari me te pumau o te wera o tā mātou momo Ultramid Ccycled hou ki ngā momo tuku iho, ā, ka āwhina anō hoki i ō mātou kiritaki ki te whakatutuki i ā rātou whāinga pumau."
•(2). Whakamahi: Whakamahia te kapia Dow PCR
I te 11 o Hune, i pānuitia ngātahi e Dow rāua ko Mengniu kua angitu rāua ki te hokohoko i te kiriata whakangote wera hangarua a te kaihoko.
E mōhiotia ana koinei te wā tuatahi i roto i te umanga kai o te motu kua whakakotahi a Mengniu i tōna kaha ā-ahuwhenua ahumahi me te hono atu ki ngā kaiwhakarato rauemi mata kirihou, ngā kaihanga takai, ngā kaihanga hangarua me ētahi atu rōpū mekameka ahumahi ki te whakatutuki i te hangarua me te whakamahi anō i ngā takai kirihou, me te whakamahi katoa i ngā kirihou hangarua muri-kaihoko hei kiriata takai Hua.
Ko te paparanga waenga o te kiriata whakangū wera tuarua e whakamahia ana e ngā hua Mengniu i ahu mai i te tauira kapia PCR a Dow. Kei roto i tēnei tauira he 40% o ngā rauemi hangarua i muri i te kaihoko, ā, ka taea te whakapiki i te ihirangi rauemi hangarua i roto i te hanganga kiriata whakangū katoa ki te 13%-24%, ka taea ai te hanga kiriata me te mahi e rite ana ki te kapia wahine. I taua wā anō, ka whakaitihia te nui o ngā para kirihou i roto i te taiao, ā, ka tino whakatinanahia te tono kati o te hangarua takai.
•(3). Unilever: Te huri ki rPET mō āna raupapa mea kakara, ka huri hei UK'te waitohu kai tuatahi 100% PCR
I te marama o Mei, i huri te waitohu mea kakara a Unilever, a Hellmann's, ki te PET hangarua-muri-kaihoko (rPET) 100%, ā, i whakarewahia ki te UK. I kī a Unilever mēnā ka whakakapia katoatia ēnei raupapa ki te rPET, ka penapenahia e ia te 1,480 tana o ngā rauemi mata i ia tau.
I tēnei wā, tata ki te haurua (40%) o ngā hua a Hellmann kua whakamahi kē i te kirihou hangarua, ā, kua tae ki ngā whata i te marama o Mei. Kei te whakamahere te kamupene ki te huri ki te kirihou hangarua mō tēnei raupapa hua i te mutunga o te tau 2022.
I kī a Andre Burger, te tumuaki tuarua o te kai i Unilever UK me Ireland:"Tō mātou Hellmann'Ko ngā pounamu whakakīkī a Unilever tā mātou waitohu kai tuatahi i te UK ki te whakamahi i te kirihou hangarua 100% i muri i te whakamahinga o te kaihoko, ahakoa he maha ngā wero i roto i tēnei nekehanga, engari mā te wheako ka taea e mātou te tere ake te whakamahi i te kirihou hangarua puta noa i Unilever.'ētahi atu waitohu kai."
Kua riro te PCR hei tapanga mōECO-ngā rauemi hoa. He maha ngā whenua o Ūropi kua whakamahi i te PCR ki ngā takai kai hei whakarite kia 100%ECO-hoa
He kaihanga mātou e tohunga ana ki te hanga i ngā putea tākai kawhe mō ngā tau neke atu i te 20. Kua noho mātou hei tētahi o ngā kaihanga putea kawhe nui rawa atu i Haina.
Ka whakamahia e mātou ngā takirere WIPF kounga teitei mai i Huiterangi hei pupuri i te hou o tō kawhe.
Kua whakawhanakehia e mātou ngā putea e pai ana mō te taiao, pērā i ngā putea ka taea te whakawairakau me ngā putea ka taea te hangarua.,me ngā rauemi PCR hou kua whakaurua mai.
Koinei ngā kōwhiringa pai rawa atu hei whakakapi i ngā putea kirihou tuku iho.
Kua tāpirihia mai tā mātou rārangi utu, tēnā tukuna mai te momo putea, te rauemi, te rahi me te rahinga e hiahiatia ana e koe. Kia taea ai e mātou te whakahua i ō utu.
