Ngā Rauemi PVA Wairewa-Wai
Ka whakarerekētia ngā rauemi PVA wairewa-wai mā te whakaranu i te waipiro polyvinyl (PVA), te māngaro me ētahi atu tāpiringa wairewa-wai. He rauemi pai mō te taiao ēnei rauemi, he wairewa-wai, he pirau-koiora hoki, ā, ka taea te wairewa katoa ki te wai. I roto i te taiao tūturu, ka pakaruhia e ngā moroiti ngā hua hei hauhā waro me te wai. I muri i te hokinga ki te taiao tūturu, kāore e paitini ki ngā tipu me ngā kararehe.
