I tēnei wā e piki haere ana te mōhiotanga ki te taiao, kei te piki haere te awhi a te umanga whakapaipai i ngā mahi tauwhiro, tae atu ki te whakamahi i ngā otinga takai hoa-taiao. I roto i ēnei, ko te Polypropylene Hangarua-muri-Kaihoko (PCR PP) te mea e tū ana hei rauemi whai hua mō ngā takai whakapaipai. Me ruku tātou ki te mārama he aha te PCR PP he kōwhiringa mohio, me pēhea hoki tōna rerekētanga mai i ētahi atu momo takai matomato.
He aha te take e whakamahia ai te PCR PP mōTākai Whakapaipai?
1. Te Kawenga Taiao
I ahu mai te PCR PP i ngā kirihou kua makahia kua whakamahia kētia e ngā kaihoko. Mā te whakamahi anō i ēnei rauemi para, ka whakaitihia te hiahia mō te kirihou hou e te takai PCR PP, e ahu mai ana i ngā wahie pūmua kāore e taea te whakahou pērā i te hinu. Ehara i te mea ka tiakina noa ngā rauemi taiao engari ka whakaitihia hoki te pānga ki te taiao e pā ana ki te hanga kirihou, tae atu ki ngā tukunga hau kati kōtuhi me te kai wai.
2. Te Whakaiti i te Tapuwae Waro
Ki te whakaritea ki te hanga kirihou hou, he iti ake ngā tukunga waro i roto i te tukanga hanga o te PCR PP. E whakaatu ana ngā rangahau ka taea e te whakamahi i te PCR PP te whakaiti i ngā tukunga waro tae atu ki te 85% ki te whakaritea ki ngā tikanga tuku iho. Nā tēnei ka waiho hei kōwhiringa ātaahua mō ngā waitohu e hiahia ana ki te whakaiti i ō rātou tapuwae waro me te whai wāhi atu ki tētahi heke mai pumau ake.
3. Te Whakatutuki i ngā Ture
He maha ngā whenua, inā koa i Ūropi me Amerika Te Raki, kua whakatinana i ngā ture e whakatairanga ana i te whakamahinga o ngā rauemi hangarua i roto i ngā takai. Hei tauira, mā te Paerewa Hangarua Ao (GRS) me te paerewa Ūropi EN15343:2008 ka whakarite kia tutuki i ngā hua hangarua ngā paearu taiao me te pāpori pakari. Mā te whakamahi i ngā takai PCR PP, ka taea e ngā waitohu whakapaipai te whakaatu i tā rātou tutuki i ēnei ture, me te karo i ngā whiu, i ngā taake rānei e pā ana ki te kore tutuki.
4. Rongonui o te Waitohu
Kei te piki haere te mōhio o ngā kaihoko ki ngā pānga taiao o ngā hua e hokona ana e rātou. Mā te whiriwhiri i ngā takai PCR PP, ka taea e ngā waitohu whakapaipai te whakaatu i tā rātou whakapau kaha ki te oranga tonutanga me te kawenga taiao. Ka taea e tēnei te whakarei ake i te ingoa o te waitohu, te kukume i ngā kaihoko e aro nui ana ki te taiao, me te whakatipu i te pono i waenga i ngā kaihoko o nāianei.
He aha ngā rerekētanga o te PCR PP i ētahi atu momo takai matomato?
1. Pūtake Rauemi
He ahurei te PCR PP nā te mea i ahu mai i ngā para o muri i te kaihoko. Mā tēnei ka wehe ke atu i ētahi atu rauemi takai matomato, pērā i ngā kirihou pirau-koiora, i ngā mea rānei i hangaia mai i ngā rauemi taiao, kāore pea e tika kia waiho hei para kaihoko hangarua. Ko te motuhaketanga o tōna pūtake e whakaatu ana i te huarahi ōhanga porowhita a te PCR PP, e hurihia ai ngā para hei rauemi whai hua.
2. Ngā Ihirangi Kua Hangarua
Ahakoa he maha ngā momo takai matomato kei roto, he mea motuhake ngā takai PCR PP nā te nui o ngā rauemi hangarua. I runga i te kaihanga me te tukanga whakaputa, ka taea e te PCR PP te whakauru i te 30% ki te 100% rauemi hangarua. Ehara i te mea ka whakaitihia te taumahatanga taiao e tēnei nui o ngā rauemi hangarua, engari ka whakarite hoki kia ahu mai te nuinga o ngā takai i ngā para e kore e mutu ki ngā whenua ururua, ki ngā moana rānei.
3. Te Mahi me te Pumau
He rerekē ki ētahi whakaaro hē, kāore te takai PCR PP e whakaiti i te mahi, i te roa rānei. Nā ngā whanaketanga o te hangarau hangarua kua taea te hanga i te PCR PP he rite ki te kirihou tauhou i runga i te kaha, te mārama, me ngā āhuatanga ārai. Ko te tikanga o tēnei ka taea e ngā waitohu whakapaipai te whai hua o te takai hoa-taiao me te kore e whakararu i te tiaki hua, te wheako kaihoko rānei.
4. Ngā Tiwhikete me ngā Paerewa
He maha ngā wā ka whakamanahia ngā takai PCR PP e ngā whakahaere rongonui pēnei i a GRS me EN15343:2008. Mā ēnei tiwhikete ka tika te ine i ngā ihirangi hangarua, ā, ka piri te tukanga whakaputa ki ngā paerewa taiao me te pāpori tino pakari. Mā tēnei taumata o te māramatanga me te kawenga e wehewehe ai te PCR PP i ētahi atu rauemi takai matomato kāore pea i tirotirohia pērā.
Whakamutunga
Hei whakamutunga, ko te PCR PP mō ngā takai whakapaipai he kōwhiringa mohio, he kōwhiringa kawenga hoki mō ngā waitohu e hiahia ana ki te whakaiti i ō rātou pānga ki te taiao, me te pupuri tonu i te kounga o te hua me te makona o ngā kaihoko. Ko tōna huinga ahurei o ngā painga taiao, te nui o te ihirangi hangarua, me ngā āheinga mahi e wehewehe ana i a ia i ētahi atu momo takai matomato. I te whanaketanga tonu o te umanga whakapaipai ki te oranga tonutanga, kua rite te takai PCR PP ki te whai wāhi nui ki te hanga i tētahi heke mai e pai ake ana ki te taiao.
