An ruwaito cewa Kamfanin Hydro na Norway ya koma amfani da fasahar busasshen bututun bauxite don maye gurbin madatsar ruwan da ta gabata, ta haka ne ya inganta aminci da kare muhalli na hakar ma'adinai.
A lokacin gwajin wannan sabon mafita, Hydro ta zuba jari kimanin dala miliyan 5.5 a fannin kawar da wutsiyoyin da ke yankin hakar ma'adinai kuma ta sami takardar izinin aiki da takardar shaidar Sakatariyar Muhalli da Dorewa ta Jihar Para (SEMAS) ta bayar.
John Thuestad, Mataimakin Shugaban Zartarwa na Kasuwancin Bauxite da Alumina na Hydro, ya ce: "Hydro ta daɗe tana himma wajen haɓaka ci gaban masana'antar aluminum mai ɗorewa, don haka mun yi ƙoƙari don aiwatar da wannan yunƙurin guje wa haƙar ma'adinan bauxite.
