Kei roto i te waro whakahohe he rauemi waro i ahu mai i te waro. Ka puta te waro whakahohe mā te whakakorikori i ngā rauemi rauropi o te tipu. Kei roto i ēnei rauemi ko te waro, te anga kokonati me te rakau,te parāoa tīhi,kiri pīni soyame te nati poto (Dias et al., 2007; Paraskeva et al., 2008). I runga i te tauine iti,paru kararehee whakamahia ana hoki mō te hanga waro whakahohe. He mea noa te whakamahi i te waro whakahohe hei tango i ngā konganuku mai i ngā wai para, engari kāore i te noa tōna whakamahinga mō te pupuri i te konganuku i roto i ngā oneone poke (Gerçel and Gerçel, 2007; Lima and Marshall, 2005b). He tino pai te kaha here o te waro whakahohe i ahu mai i te paru heihei (Lima and Marshall, 2005a). He maha ngā wā ka whakamahia te waro whakahohe hei whakaora i ngā poke i roto i te oneone me te wai nā te hanganga porous, te whānui o te mata me te kaha mimiti teitei (Üçer et al., 2006). Ka tangohia e te waro whakahohe ngā konganuku (Ni, Cu, Fe, Co, Cr) mai i te otinga mā te maturuturu hei waikura konganuku, te mimiti ki runga i te waro whakahohe (Lyubchik et al., 2004). Ka tangohia pai e te kiri aramona AC te Ni mai i ngā wai para me te kore H2SO4te maimoatanga (Hasar, 2003).
Nō nā tata nei, kua whakamahia te waro koiora hei whakatikatika oneone nā te mea he pai ōna pānga ki ngā āhuatanga ā-tinana me te matū o te oneone (Beesley et al., 2010). He tino nui te ihirangi o te waro koiora (tae atu ki te 90%) i runga i te rauemi matua (Chan and Xu, 2009). Mā te tāpiri i te waro koiora ka pai ake te mimiti o te waro waro rewa.pH oneone, ka whakaiti i ngā konganuku i roto i ngā wai rere, ā, ka tāpiri i ngā matūkai nui (Novak et al., 2009; Pietikäinen et al., 2000). Ko te roa o te noho o te waro koiora ki roto i te oneone ka whakaiti i te whakaurunga o ngā konganuku mā te whakamahi anō i ētahi atu whakatikatika (Lehmann and Joseph, 2009). I whakatau a Beesley et al. (2010) i whakaitihia e te waro koiora te Cd wairewa-wai me te Zn i roto i te oneone nā te pikinga o te waro waro me te pH. I whakaitihia e te waro whakahohe te kukū konganuku (Ni, Cu, Mn, Zn) i roto i ngā wana o ngā tipu kānga i whakatipuria i roto i ngā oneone poke, ki te whakataurite ki te oneone kāore i whakatikatikaina (Sabir et al., 2013). I whakaitihia e te waro koiora ngā kukū teitei o te Cd wairewa me te Zn i roto i te oneone poke (Beesley and Marmiroli, 2011). I whakatau rātou ko te mimiti he tikanga nui mō te pupuri i ngā konganuku e ngā oneone. Nā te Biochar i whakaiti te kukū o te Cd me te Zn ki te 300 me te 45 ngā wā i heke ai te kukū o te wai rere (Beesley and Marmiroli, 2011).
