Ngā Tikanga Tukatuka o te Raina Hanga Pepa Kōhatu

Raina pepa kōhatu me ngā tikanga tukatuka, e uru ana ki te pepa hanga me tana hangarau whakaputa. Ko te pepa kōhatu he paparanga pepa turanga me te paparanga paninga, ka pania te paparanga paninga ki runga i te paparanga pepa turanga. Ko te paparanga pepa turanga he mea hanga mai i ngā wāhanga rauropi me ngā wāhanga kore-rauropi. Ko te wāhanga rauropi he waikawa polylactic, ā, ko te taumaha o te wāhanga rauropi he 15 ki te 30. Kei roto i ngā wāhanga kore-rauropi he konupūmā kāponāte māmā me te lithopone, ā, ko te taumaha o ngā wāhanga kore-rauropi he 70 ki te 85. Ko te tikanga tukatuka: whakamaroke-wera me te whakamaroke i te konupūmā kāponāte māmā me te lithopone ka whakaoho kia ōrite, kātahi ka whakaranua ki ngā wāhanga kore-rauropi ka whakaoho kia ōrite, kātahi ka mahi i te pokepoke ā-roto me te whakapūkara i roto i ngā taputapu whakapūkara. Ka tukuna te maramataka kia whiwhi ai i te paparanga pepa turanga, kātahi ka rongoatia ki te korona. Pania te rauemi paparanga paninga ki runga i te mata o te paparanga pepa turanga. He hoa taiao, he ngāwari, ā, he ātete ki te takai me te haehae, he pai mō ngā waituhi noa, ā, ka taea te whakamahi hei pepa ahurea, pepa kai me te hauora, pepa pukatuhi me te pukapuka ako, pepa tā, me ētahi atu.

te Te hanga pepa kōhatu PE He maha ngā momo pepa kōhatu me ngā tikanga tukatuka a te raina, tae atu ki te pepa hangai me tana hangarau whakaputa. He momo pepa kōhatu, kei roto ko te paparanga pepa turanga me te paparanga paninga, ka pania te paparanga paninga ki runga i te paparanga pepa turanga. He mea tito te paparanga pepa turanga i ngā wāhanga rauropi me ngā wāhanga kore-rauropi. Ko te wāhanga waro he polypropylene, ā, ko te taumaha o te wāhanga waro he 20 ki te 30. Kei roto i ngā wāhanga kore-waro ko te konupūmā kāponāte māmā me te lithopone, ā, ko te taumaha o ngā wāhanga kore-waro he 70 ki te 80. Ko te tikanga tukatuka: whakamarokehia te konupūmā kāponāte māmā me te lithopone ka whakaohokia kia ōrite, kātahi ka whakaranua ki ngā wāhanga kore-waro ka whakaohokia kia ōrite, kātahi ka mahia te pokepoke ā-roto me te whakapūkara i roto i ngā taputapu whakapūkara. Ka puta te maramataka hei tiki i te paparanga pepa turanga, kātahi ka rongoatia ki te korona. Pania te rauemi paparanga paninga ki runga i te mata o te paparanga pepa turanga. He pai ki te taiao, he ngāwari, ā, he ātete ki te takai me te haehae, he pai mō ngā waituhi noa, ā, ka taea te whakamahi hei pepa ahurea, pepa kai me te pepa hauora, pepa pukatuhi me te pukapuka ako, pepa tā, me ētahi atu.

He momo rauemi hou te pepa kōhatu PE, he maha ngā painga me ngā whakamahinga.

He mea hanga te nuinga mai i te paura kōhatu me te polyethylene (PE) mā roto i ngā tukanga motuhake. He ātete wai, he ātete hinu, he ātete makuku, ā, he ātete huka. He ātete haehae, he ātete takai, ā, kāore e ngāwari ki te haehae. He pai mō ngā momo tikanga tā, he tino pai mō ngā putea pepa, ngā putea ringaringa, me ētahi atu. Kāore te tukanga whakaputa o tēnei rauemi e kai wai, kāore e whakamahi hinu, rākau rānei, kāore e hiahiatia he keri nui, kāore e tuku para, he ma te taiao whakaputa, kāore he haruru, he iti te utu, he momo rauemi i waenga i te pepa me te kirihou hou.

Kāore e taea e te pepa kōhatu PE te whakakapi i ētahi pepa mahi tuku iho me ngā pepa ngaio anake, engari ka whakakapi hoki i te nuinga o ngā takai kirihou tuku iho, ā, he kaha tōna mōhiotanga ki te taiao. Kāore e hiahiatia he horoi ki te wai i te wā e hangaia ana, ā, kāore e hiahiatia he waikawa kaha, he kawakore kaha me te mā, nō reira kāore he raruraru o te tukunga wai para, ā, kāore e whakapoke i ngā rauemi wai pērā i ngā awa me ngā moana. Ā, he iti ake te kaha e pau ana i te hanga pepa penupenu rakau tuku iho, e āwhina ana ki te whakapai ake i ngā take pērā i te mahana o te ao i puta mai i te hauhā waro (CO2).

Hei whakarāpopototanga, ehara i te mea he rauemi hou e pai ana ki te taiao te pepa kōhatu PE, engari he maha hoki ōna painga pērā i te iti o te utu, te āheinga ki te hangarua me te pirau, ā, e matapaetia ana ka waiho hei hua e pai ana ki te taiao ka whakamahia whānuitia ā muri ake nei.
