E whakaatu ana ngā tātaritanga mākete me ngā whanaketanga ahumahi hou i te aro nui ki te sulfolane, he whakarewa aprotic polar mahi-teitei, i te mea e rapu ana ngā rāngai mai i ngā matū hinu ki ngā rongoā i ngā rauemi whai hua ake, e hototahi ana ki te taiao. Me tōna huinga ahurei o te pumau wera, te wairewatanga teitei, me te iti o te paitini, kei te puta ake te sulfolane hei kaiwhakahohe matua mō ngā tukanga e whakatairanga ana i te whai huatanga o te mahi me ngā whāinga pumau.

Ko te Rāngai Matū Kete te Arataki i te Whakamahinga o te Tukatuka Hau Taiao

Ko te umanga matū hinu tonu te kaihoko nui rawa atu o te sulfolane, e whakamahi ana i tōna kaha ki te wehewehe i ngā matū whanariki mai i ngā awa hau māori me ngā awa whakarewa. I te mea ka kaha haere ngā ture ā-ao mō ngā tukunga whanariki—e aro ana ki te whakaiti i te parahanga o te hau me te whakaiti i te pānga o te āhuarangi—kei te tahuri ngā kaiwhakahaere ki ngā pūnaha tango sulfolane hei whakatutuki i ngā herenga kaha o te ihirangi whanariki mō ngā wahie me te hau māori.

He rerekē ki ngā whakarewa tuku iho, ka mau tonu te mahi pumau o te sulfolane i ngā pāmahana teitei (tae atu ki te 285°C) ā, ka ātete ki te pirau, ka whakaiti i te hiahia mō te whakakapinga whakarewa auau me te whakaiti i ngā utu whakahaere whānui. E kī ana ngā pūrongo ahumahi kua tere ake ngā haumitanga ki ngā whare whakapai hinu me ngā tipu tukatuka hau māori i ngā rohe he iti ngā paerewa tukunga i roto i ngā marama 12 kua pahure ake nei, he ia e matapaetia ana ka haere tonu tae noa ki te tau 2026.

Whakawhanui ake te Whakamahinga o ngā Ahumahi Rongoā me ngā Matū Pai

Haunga ngā matū hinu, kei te whakawhānui ake ngā rāngai rongoā me ngā rāngai matū pai i tā rātou whakamahinga o te sulfolane hei reo tauhohenga me te whakarewa tango. Nā tōna kaha ki te whakarewa i ngā matū polar me ngā matū kore-polar, he mea tino pai mō te hanga i ngā kai rongoā hohe (API) me ngā matū motuhake, he mea nui te tika me te parakore.

Kua arohia hoki e ngā whanaketanga hangarau o nāianei ngā āwangawanga o mua mō te whakaora i te whakarewa, me ngā hangarau whakahoro me te purenga hou e āhei ai te hangarua i te sulfolane i ngā tere neke atu i te 95% i roto i te hanga rongoā. Ehara i te mea ka whakaitihia noa te para engari ka hangai anō hoki ki te pana a te umanga ki ngā mahi ōhanga porowhita, e akiaki ana i te whakamahinga.

Arotahi ki te Whakaputa Tauwhiro me te Porowhita

I te pikinga ake o te tono, kei te neke haere te aro ki te hanga sulfolane tonu. Kei te tūhuratia e ngā kaihanga ngā rauemi whāngai koiora me ngā huarahi hanga-pūngao-pai hei whakaiti i te tapuwae waro o te hanga sulfolane, me ngā kaupapa whakamātautau tuatahi e whakaatu ana i te kaha ki te whakaiti i ngā tukunga hau kati kōtuhi ki te 20% ki te whakataurite ki ngā tikanga tuku iho.

Hei tāpiritanga, kei te haere tonu ngā mahi tahi a ngā umanga ki te whakawhanake i ngā aratohu paerewa mō te hangarua sulfolane puta noa i ngā rāngai, me te whai kia kotahi ake te huarahi ki te whakaiti i te para o te whakarewa. E tautokona ana ēnei mahi e ngā rōpū whakahaere e mōhio ana ki te iti o te pānga o te sulfolane ki te taiao ina whakahaeretia tika, e whakanoho ana i a ia hei huarahi kē atu i ngā whakarewa morearea.

Tirohanga: Te Tipu Pūmau e Ārahihia ana e te Ture me te Auahatanga

E ai ki ngā matapae mākete, ka piki ake te hiahia o te ao mō te sulfolane i te tere ā-tau o te 4.5% i roto i ngā tau e rima e whai ake nei, nā ngā ture tukunga tonu, ngā whanaketanga o te hanga rongoā, me te whānui haere o ngā hanganga tukatuka hau māori. E whakanui ana ngā tohunga ko te maha o ngā whakamahinga o te sulfolane—me tōna hototahi ki ngā mahi tauwhiro—ka noho tonu ki mua i ngā whiringa whakarewa ahumahi mō ngā tau e haere ake nei.

"I a ngā umanga e whakatere ana i ngā wero e rua o te whakapai ake i te whai huatanga me te whakaiti i te pānga ki te taiao, kāore ngā whakarewa pēnei i te sulfolane e noho hei taputapu whakahaere noa iho—he rawa rautaki hoki," te kī a tētahi kaikorero mō tētahi whakahaere umanga matua. "Ko te auahatanga tonu ki te āhua o tā tātou whakaputa, whakamahi, me te hangarua i te sulfolane ka whakakaha ake i tōna tūranga ki te hanga pūnaha ahumahi pumau ake."
