Penapenahia te pāhare pākawa waro ki roto i ngā ipu kua hiritia, ātete ki te waikura (he pai ake te HDPE, te karāhe rānei) ki roto i te rokiroki hauhautanga, maroke, me te hauhautanga pai. Tāpirihia ngā tapanga ki ngā ipu katoa kia tika. Puritia kia matara atu i te rā, i ngā pūtake wera, me ngā poke pea. He mea nui te wehewehe ā-tinana: kaua rawa e penapena ki ngā waikawa, ki ngā rauemi mura, ki ngā matū whakaiti rānei.
Āraihia te tukunga ki te wai, ki te oneone, ki ngā waikeri rānei. Mā te pupuri i ngā mea tuarua, pērā i ngā paepae ātete matū i raro i ngā oko rokiroki, ka āwhina i te aukati i ngā turuturu tūpono kei tae atu ki te taiao. Mō te whakakorenga, me whakakore ngā otinga pāhare pākawa waro—i raro i ngā tikanga whakahaere me te whakamahi i tētahi matū whakaiti tika—i mua i te whakahaerenga hei para kino. Makahia ngā rauemi horoi katoa me ngā horoi kia rite ki ngā ture ā-rohe hei tiaki i te kounga o te wai me ngā rauropi.
Ki te puta he turuturu, wehea tonutia te wāhi, ka tangohia ngā pūtake mura. Whakamahia noa ngā mea mimiti kore e mura, kore e mura, hei horoi. Kaua e tahia, e tangohia rānei ngā matū maroke ki te mīhini horoi – he pai ake te horoi mākū me ngā PPE. Ka whakahaerea ngā toenga turuturu katoa hei para morearea, ā, me tuhi kia rite ki ngā ture taiao.
