Ko te ingoa katoa o PCR ko te Post-Consumer Recycled material, arā, ko ngā rauemi hangarua, e pā ana ki ngā rauemi hangarua pērā i te PET, PP, HDPE, me ētahi atu, kātahi ka tukatukahia ngā rauemi mata kirihou e whakamahia ana hei hanga rauemi tākai hou. Ki te kī, ka whakahokia mai he ora tuarua ki ngā tākai kua makahia.
He aha i whakamahia ai te PCR i roto i ngā takai?
Nā te mea he āwhina tēnei ki te tiaki i te taiao. He maha ngā wā ka tukatukahia ngā kirihou tauhou mai i ngā rauemi mata matū, ā, he nui ngā painga o te tukatuka anō mō te taiao.
Whakaarohia, ka nui ake te hiahia mō te PCR, ka nui ake te tono. Nā tēnei ka nui ake te hangarua o ngā takai kirihou kua whakamahia, ā, ka whakatairanga ake i te tukanga arumoni o te hangarua para, ko te tikanga he iti ake te kirihou e mutu ana ki ngā whenua ururua, ki ngā awa, ki ngā moana.
He maha ngā whenua o te ao e whakatinana ana i ngā ture e whakahau ana i te whakamahinga o ngā kirihou PCR.
Mā te whakamahi i te kirihou PCR ka tāpirihia he whakaaro kawenga mō tō waitohu ki te taiao, ā, ka waiho hoki tēnei hei wāhanga nui o tō waitohu.
He tokomaha hoki ngā kaihoko e hiahia ana ki te utu mō ngā hua kua tākaihia ki te PCR, ā, ka nui ake te uara arumoni o āu hua.
He aha ngā ngoikoretanga o te whakamahi i te PCR?
He mārama noa iho, kāore e tika kia whakamahia te PCR, hei rauemi hangarua, mō te tākai i ētahi hua he tino teitei ngā paerewa akuaku, pērā i ngā rongoā me ngā taputapu hauora.
Tuarua, he rerekē pea te tae o te kirihou PCR i te kirihou tauhou, ā, tera pea he iraira, he tae poke rānei kei roto. Waihoki, he iti ake te matotoru o te rauemi kirihou PCR i te kirihou tauhou, ā, he uaua ake te whakakirikiri, te tukatuka rānei.
Engari ina whakaaetia tēnei rauemi, ka taea te whakakore i ngā uauatanga katoa, ā, ka taea te whakamahi pai ake i ngā kirihou PCR i roto i ngā hua e tika ana. Heoi anō, kāore koe e hiahia ki te whakamahi i te 100% PCR hei rauemi tākai i te tīmatanga, he tīmatanga pai te 10%.
He aha te rerekētanga i waenga i te kirihou PCR me ētahi atu kirihou "kakariki"?
Ko te PCR e pā ana ki te takai o ngā taonga kua hokona i ngā wā noa, kātahi ka pā ki ngā rauemi mata o te takai i hangaia i muri i te hangarua. He maha anō hoki ngā kirihou kei te mākete kāore i te hangarua rawatia ki te whakataurite ki ngā kirihou noa, engari he nui tonu ngā painga ki te taiao.
hei tauira:
-> PIR, e whakamahia ana e ētahi hei wehewehe i te Resin Muri i te Kaihoko me te Resin Muri i te Ahumahi. Ko te pūtake o te PIR ko ngā pouaka me ngā papa kawe i roto i te mekameka tohatoha, tae atu ki ngā pūwero, ngā waitohu iti, ngā hua hapa, me ētahi atu mea i puta mai i te wā e tangohia tika ana ngā hua werohanga wheketere, me ētahi atu mea, mai i te wheketere me te whakamahi anō. He pai hoki mō te taiao, ā, he pai ake i te PCR mō ngā monolith.
-> Ko ngā kirihou koiora, inā koa ko ngā biopolymer, e pā ana ki ngā kirihou i hangaia mai i ngā rauemi mata i tangohia mai i ngā mea ora pēnei i ngā tipu, kaua ki ngā kirihou i hangaia mai i te hanganga matū. Ehara i te mea ko te tikanga o tēnei kupu he pirau te kirihou, ā, ka taea te hē te whakamārama.
-> Ko ngā kirihou pirau-koiora me ngā kirihou wairākau e pā ana ki ngā hua kirihou e tere ake ana te pirau i ngā hua kirihou noa. He nui te tautohetohe i waenga i ngā tohunga ahumahi mō te pai o ēnei rauemi mō te taiao, nā te mea ka whakararuraru i ngā tukanga pirau koiora noa, ā, ki te kore e tino pai ngā āhuatanga, kāore e pakaru hei matū kino. Heoi anō, kāore anō kia mārama te tere o te pirau.
Hei whakamutunga, ko te whakamahi i tētahi ōrau o ngā pūmua hangarua ki roto i ngā takai e whakaatu ana i tō kawenga hei kaihanga mō te tiaki taiao, ā, he tino takoha nui tēnei ki te kaupapa tiaki taiao. Me mahi i ngā mea maha, he aha ai e kore ai.
