Phenolyikhemikhali ebalulekileyo yemizi-mveliso esetyenziswa kuluhlu olubanzi lwezicelo, kubandakanywa ukuveliswa kweplastiki, isicoci kunye namayeza. Ukuveliswa kwephenol ehlabathini lonke kubaluleke kakhulu, kodwa umbuzo uhlala usithi: ngowuphi owona mthombo ubalulekileyo wale nto ibalulekileyo?

Uninzi lwemveliso yehlabathi yephenol luvela kwimithombo emibini engundoqo: amalahle kunye negesi yendalo. Ubuchwephesha be-Coal-to-chemical, ngokukodwa, buguqule ukuveliswa kwe-phenol kunye nezinye iikhemikhali, ukubonelela ngeendlela ezifanelekileyo kunye neendleko zokuguqula amalahle kwiikhemikhali zexabiso eliphezulu. E-China, umzekelo, iteknoloji yamalahle ukuya kwiikhemikhali yindlela esekelwe kakuhle yokuvelisa i-phenol, kunye nezityalo ezihlala kulo lonke ilizwe.

Umthombo wesibini omkhulu wephenol yigesi yendalo. Ulwelo lwegesi yendalo, olufana ne-methane kunye ne-ethane, lunokuguqulwa lube yi-phenol ngothotho lweentshukumo zemichiza. Le nkqubo inamandla kakhulu kodwa iphumela kwi-phenol ephezulu ecocekileyo ebaluleke kakhulu ekuveliseni iiplastiki kunye neesepha. I-United States ngumvelisi ohamba phambili we-phenol esekelwe kwigesi yendalo, enezixhobo ezibekwe kwilizwe lonke.

Imfuno ye-phenol iyanda kwihlabathi liphela, iqhutywa zizinto ezinjengokukhula kwabemi, ukukhula kwamashishini, kunye nokufudukela kwabantu ezidolophini. Le mfuno kulindeleke ukuba iqhubeke ikhula kwiminyaka ezayo, kunye nezibikezelo ezibonisa ukuba imveliso yehlabathi jikelele ye-phenol iya kuphinda kabini ngo-2025. Ngaloo ndlela, kubalulekile ukuqwalasela iindlela ezizinzileyo zokuvelisa ezinciphisa impembelelo yokusingqongileyo ngelixa ihlangabezana nemfuno ekhulayo yehlabathi yale khemikhali ibalulekileyo.

Ukuqukumbela, uninzi lwemveliso yehlabathi yephenol luvela kwimithombo emibini ephambili: amalahle kunye negesi yendalo. Ngelixa yomibini le mithombo inezibonelelo zayo kunye nokungalunganga, ihlala ibalulekile kuqoqosho lwehlabathi, ngakumbi kwimveliso yeeplastiki, ezokucoca, kunye namayeza. Njengoko imfuno ye-phenol iqhubeka nokunyuka kwihlabathi jikelele, kubalulekile ukuqwalasela iindlela ezizinzileyo zokuvelisa ezilinganisa iimfuno zoqoqosho kunye neenkxalabo zokusingqongileyo.
