Ko ngā takai kirihou whakapaipai noa ko te PP, PE, PET, PETG, PMMA (kiririka) me ērā atu. Mai i te āhua o te hua me te tukanga whakapūtanga, ka taea e tātou te mārama ngāwari ki ngā pounamu kirihou whakapaipai.
Tirohia te āhua.
He matotoru ake, he mārō ake te rauemi o te pounamu kiriaku (PMMA), ā, he rite tōna āhua ki te karāhe, he ngāwari te uru ki roto pērā i te karāhe, ā, kāore e pakarukaru. Heoi, kāore e taea te pa tika atu o te kiriaku ki te tinana o te rauemi, me ārai e te pūkahukahu o roto.
(Pikitia:Ipu Kirīmi Kore-hau PJ10(He mea hanga te ipu o waho me te taupoki ki te rauemi kiriaku)
Mā te putanga mai o te rauemi PETG ka ea tēnei raruraru. He rite te PETG ki te kiriaku. He matotoru ake, he mārō ake te rauemi. He rite tōna kakano ki te karāhe, ā, he mārama te pounamu. He pai ōna āhuatanga ārai, ā, ka taea te pā tika ki te rauemi o roto.
Tirohia te mārama/te maeneene.
He huarahi pai hoki ki te wehewehe mēnā he mārama te pounamu (tirohia ngā ihirangi, kāore rānei) ā, he maeneene hoki. Hei tauira, he mārama te nuinga o ngā pounamu PET, ā, he tino mārama. Ka taea te hanga hei mata matte, kanapa hoki i muri i te whakakōhua. Koinei ngā rauemi e whakamahia whānuitia ana i roto i te umanga inu. Ko ā mātou pounamu wai kohuke noa he rauemi PET. Waihoki, he whānuitia te whakamahinga i roto i te umanga whakapaipai. Hei tauira, ka taea te tākai i ngā mea whakamakuku, ngā mea pahuka, ngā hopi horoi ringa, me ētahi atu mea ki roto i ngā ipu PET.
(Pikitia: Pounamu whakamakuku hukapapa 200ml, ka taea te taurite ki te taupoki, te pūwero kohu)
He mārama, he ngawari ake hoki ngā pounamu PP i te PET. He maha ngā wā ka whakamahia hei takai i ngā pounamu hopi horoi (he ngāwari ki te pēhi), ā, ka taea te maeneene, te mātotoru rānei.
He mātotoru te āhua o te pounamu PE, ā, kāore te tinana o te pounamu i te maeneene, e whakaatu ana i te kanapa matte.

Māeneene: PET (mata maeneene/mata onepu)>PP (mata maeneene/mata onepu)>PE (mata onepu)
Tirohia te raro o te pounamu.
Heoi anō, he ara māmā ake, he ara whanoke hoki hei wehewehe: tirohia te raro o te pounamu! He rerekē ngā tukanga whakahāngai ka hua ake he rerekē ngā āhuatanga o te raro o te pounamu.
Hei tauira, ka whakamahia te pounamu PET hei pupuhi totoro werohanga, ā, he pūwāhi rauemi porowhita nui kei raro. Ka whakamahia te pounamu PETG hei hanga pupuhi whakaputa, ā, he pūwāhi raina kei raro o te pounamu. Ka whakamahia te PP hei hanga werohanga, ā, he iti te pūwāhi rauemi porowhita kei raro.
I te nuinga o te wā, he raruraru kei te PETG pērā i te utu nui, te tere para nui, ngā rauemi kāore e taea te hangarua, me te tere whakamahinga iti. Ko ngā rauemi kiriaku e whakamahia ana i roto i ngā mea whakapaipai utu nui nā te mea he nui te utu. He rerekē, ko te PET, PP, me te PE te mea e whakamahia whānuitia ana.
Ko te pikitia i raro nei ko te raro o ngā pounamu pahuka e toru. Ko te mea kikorangi-kakariki he pounamu PE, ka kitea he rārangi tika i raro, ā, he mata matte tūturu te pounamu. Ko ngā mea mā me ngā mea mangu he pounamu PET, me te ira kei waenganui o raro, he kanapa tūturu.
