II. He aha te Kapu Aikurīmi Pirau-ā-Tūroa
A. He kupu whakataki ki te kapu gelato pirau
Ko te kapu gelato pirau-ā-taiao he momo ipu kāore e taea te whakamahi anō, he mea hanga mai i ngā hua ka taea te pakaru i roto i te taiao, engari kāore e whara.

I te āhua, he rerekē ngā kapu inu makariri pirau-ā-taiao i ngā kapu i hangaia ki ngā kirihou hinu. Ka taea e koe te tirotiro i ngā kai o te takai hua māu ake mā te titiro tata ki te raro o tētahi mea kirihou. Ka kitea e koe he tau i roto i tētahi tapatoru i hangaia ki ngā pere. Ka kiia tēnei ko te tohu rauemi, ā, kei waenga i te 1 ki te 7 ngā tau. Ko ia tau e rite ana ki tētahi rauemi rerekē. Mō ngā kapu kirihou noa, ko te waehere ko te 5, e rite ana ki te polypropylene. He polymer thermoplastic totoka te polypropylene e mahi ana hei ārai makuku, ā, he ātete ki te wera. Ahakoa he uaua, he ātete hoki ki te maha o ngā whakarewa, ka taea te whakamahi anō. I tētahi atu taha, ki te mutu ki te whenua ururua, ka roa pea te wā.20 ki te 500 taukia pirau rawatia.
