Whakarāpopototia te tuhinga:  Kua whakarewahia he wharepaku tauira e whakaputa ana i te hiko 'kaore e mutu' mai i te urine i te taha o te paari o te whare wananga. E tūmanako ana ngā kaipūtaiao i muri i te wharepaku 'pī-mana' ka taea te whakamahi e ngā whakahaere āwhina i ngā rohe parekura ki te tuku hiko e hiahiatia ana ki ngā puni rerenga. E whakamahi ana te hangarau i ngā pūkaha pūngao moroiti i roto i ngā wharepaku, e kai ana i te urine, e waihanga ana i te pūngao koiora ka taea te huri hei hiko. Panuku ki raro mō te ataata. Kua whakarewahia he wharepaku tauira e whakaputa ana i te hiko'mau tonu' mai i te urine i te taha tata o te whare wananga (whakaahua o te taonga). E tūmanako ana ngā kaipūtaiao i muri i te wharepaku'pee-power'ka taea te whakamahi e ngā whakahaere āwhina i ngā rohe parekura ki te tuku hiko e tino hiahiatia ana ki ngā puni rerenga. Ko te urinal te hua o te hononga i waenga i nga kairangahau i te Whare Waananga o te Hauauru o Ingarangi i Bristol me Oxfam. Kei roto i ngā waeine he huakita e whakaheke ana i ngā matū i roto i te urine, i te tukanga e tuku ana i te pūngao i roto i te āhua o te hiko e penapenahia ana ki runga i tētahi pūngao i roto i te pūhiko wahie. "Ko ngā pūhiko wahie moroiti (MFC) e mahi ana mā te whakamahi i ngā moroiti ora e kai ana i te urine mō tō rātou ake tupu me te tiaki", te whakamārama a Pōrofesora Ioannis Ieropoulos. "Ko te MFC, i roto i te tikanga, he punaha e tango ana i tetahi waahanga o taua kaha koiora. 'He āhua matomato tēnei hangarau, nā te mea kāore e hiahiatia ana e tātou te whakamahi i ngā pūngao kōhuri, ā, kei te whakamahi mātou i tētahi hua ururua ka nui te tuku.' Kei te taha o te uniana o ngā ākonga i te whare wānanga o Frenchay o te whare wānanga, ā, e tūmanako ana ngā kairangahau kia pai te mahi i te wā kati. E tonoa ana ngā ākonga me ngā kaimahi kia whakamahi i te urinal ki te tuku i te pī hei pūngao mō ngā pūhiko pūngao microbial e whakaputa ana i te hiko hei whakaoho i ngā rama o roto. Ko te rōpū rangahau e ārahihia ana e te Ahorangi Ioannis Ieropoulos, o te Bristol Robotics Laboratory i UWE Bristol, he tohunga ia ki te whakamahi i te mana mai i nga puna rereke ma te whakamahi i nga pūhiko wahie moroiti. 'Kua whakaaturia e mātou e mahi ana tēnei huarahi whakaputa hiko,' i mea te pouako. 'Ka mahi i te Bristol...
E ai ki ngā kaipūtaiao ka taea te whakamahi i te wharepaku hei tuku hiko ki ngā rohe parekura. Ka whakamahia e te pūnaha Bristol ngā pūngao moroiti i roto i ngā wharepaku e kai ana i te urine. Ka waihanga tēnei i te pūngao koiora ka taea te huri hei hiko. E ai ki ōna kaihanga, he iti iho te utu o te pūnaha i te £600 ($900) hei whakarite.
