Emigqeni yokukhiqiza ezenzakalelayo esheshayo yama-napkin nama-napkin ahlanzekile, umzuzwana ngamunye wokungasebenzi usho ukulahlekelwa yimali etholakale kanzima. Ukuqinisekisa ukuthi umkhiqizo awubi yingozi, inqubo yokubulala amagciwane e-corona iqhubeka unyaka wonke ezindaweni zokukhiqiza; ngenkathi lokhu kubulala amagciwane, kukhipha nenani elikhulu le-ozone. Ezinhlelweni zokushayela, i-ozone “iwubuthi obusebenza kancane” obufihliwe.

Izimboni eziningi ziye zabhekana nezinkinga ezifanayo: amabhande avamile ahambisanayo, uma esebenza endaweni ecebile nge-ozone, ngokushesha aqala ukuba yimpuphu ebusweni, ukuqhekeka okujulile, noma ngisho nokuqhekeka ngaphandle kwesixwayiso. Ukushintsha njalo akugcini nje ngokukhuphula izindleko zokusebenza nokugcinwa kodwa futhi kuphazamisa nesimiso sokukhiqiza esiqinile. Kwinkampani enkulu yemikhiqizo yokuhlanzeka yaseMelika eyasungulwa ngo-1872, noma iyiphi ingozi engaba khona ethinta umthamo wokukhiqiza kanye nezindinganiso zokuhlanzeka kumele isuswe. Ngakho baphendukela kithi—umkhiqizi wamabhande ahambisanayo amelana ne-ozone agxile ezixazululweni ezikhethekile zokudlulisa—benethemba lokuqeda leli phupho elibi “lokwehluleka kwebhande ngaphambi kwesikhathi.”

I. Ubuhlungu Obufihliwe Ngemuva Kwenkampani Eneminyaka Eyikhulu

Njengoba zingena endaweni yokukhiqizwa kwalesi sikhulu semikhiqizo yokuhlanzeka saseMelika esineminyaka eyikhulu, amashumi ezinkulungwane zemikhiqizo yokuhlanzeka aqala ukuhlangana njalo ngeminithi. Kodwa-ke, ukuchayeka isikhathi eside ku-ozone enokugcwala okuphezulu kuye kwaba nomthelela omkhulu kumabhande ajwayelekile ahambisanayo emigqeni yokukhiqiza. Njengoba ayeguquguquka ekuqaleni, la mabhande ahambisanayo alahlekelwa ukunwebeka kwawo ezinyangeni ezimbalwa nje ngaphansi kokuhlaselwa njalo yi-ozone, ubuso bawo bumbozwa imifantu emincane futhi ngisho nasengcupheni yokuchitheka kwezinhlayiya.

 

Enkampanini eneminyaka eyikhulu ubudala ephatha ikhwalithi njengegazi layo lokuphila, lokhu bekungabekezeleleki. Ababekudinga ngokushesha kwakungeyona nje ibhande elihambisanayo elingamelana ne-ozone, kodwa uhlelo lokushayela oluphelele olukwazi ukusebenza kahle isikhathi eside ezimweni "ezinzima" ezinjalo. Lokhu akuyona nje indaba yokushintsha izingxenye; kuyimpi yokuvikela ukusebenza kahle kokukhiqiza kanye nedumela lomkhiqizo.

II. Ukwandisa Isikhathi Sokuphila Kwebhande Lesikhathi Ezingeni Lama-Molecular

 

Njengomkhiqizi ochwepheshe wamabhande okugcina isikhathi amelana ne-ozone, siyaqonda ukuthi ukubhekana nembangela kubaluleke kakhulu kunokwelapha izimpawu nje kuphela. Lapho sithola isicelo, ithimba lethu le-R&D laya ngokushesha endaweni ukuze lenze uphenyo olunzulu ngokugcwala kwe-ozone, ukucindezeleka kokusebenza, kanye namazinga okuhlanzeka.

 

Umsuka wenkinga wawusebuthakathakeni besakhiwo samakhemikhali bezinto ezivamile—ubuthaka obungasetshenziswa kalula yi-ozone. Ukuze sibhekane nalokhu, sakha indlela yokwenza ngokwezifiso eyenzelwe ngqo le nkampani enkulu: ngokushintsha ngokuphelele uhlelo lwezinto eziyisisekelo nokufaka izingxenye zokuvikela ezingasebenzi kahle ezakhiwe ngokukhethekile, sakha ukuzivikela kwamakhemikhali okuqinile ezingeni elincane kakhulu. Leli bhande elihambisanayo elimelana ne-ozone elenziwe ngokwezifiso linikeze ukusebenza okuvelele ekuhlolweni kokuguga okusheshayo okuqinile—ngisho nangemva kokuchayeka isikhathi eside ku-ozone, lagcina ukuguquguquka namandla amahle kakhulu, alizange likhiqize udoti ngesikhathi sokusebenza, futhi lahlangabezana ngokugcwele nezidingo zokukhiqiza ukuhlanzeka okuphezulu.

 

Lapho amabhande amasha esikhathi esebenza kahle emgqeni wokukhiqiza izinyanga eziningi futhi ehlala emuhle njengentsha, ibunzi lekhasimende eligobile ekugcineni lakhululeka. Lokhu akugcini nje ngokwandisa impilo yesevisi kodwa futhi kwanikeza nokuvikelwa okuqinile kokuqhubeka kokukhiqiza.

 

III. Ukuphendula Kuyo Yonke Impahla Ephathiswe Amakhono Aqinile

 

Ukuthola ukwethenjwa kwalesi sikhulu semikhiqizo yokuhlanzeka saseMelika esineminyaka eyikhulu, esasungulwa ngo-1872, kwakungeyona neze impumelelo eyenzeka ngobusuku obubodwa. Singumkhiqizi wamabhande ahambisanayo amelana ne-ozone ahlanganisa i-R&D, ukukhiqizwa, kanye nokuthengisa, nethimba lonjiniyela abangu-35 eligxile kakhulu embonini kanye nelabhorethri yezinto ezihlonyiswe ngokugcwele. Kungakhathaliseki ukuthi kuhilela izimo zokusebenza ezikhethekile njengokumelana ne-ozone, ukumelana nokushisa okuphezulu, noma ukumelana ne-asidi ne-alkali, singasabela ngokushesha ukuhlinzeka ngezinsizakalo zokwenza ngokwezifiso zobungcweti zamabhande ahambisanayo amelana ne-ozone.

 

Siyaqonda ubuchwepheshe, futhi siyaqonda izidingo zamakhasimende ethu kangcono nakakhulu. Kusukela ekuhlolweni kokuqala kwezimo zokusebenza kanye nokukhethwa kwezinto kuya ekuhlolweni kwamasampula, ukukhiqizwa ngobuningi, kanye nokulandelwa kokuthengiswa ngemuva kokuthengiswa, sinikeza ukwesekwa kobuchwepheshe komuntu ngamunye kuyo yonke inqubo. Siyaqonda ukuthi amakhasimende ethu awakhethi nje kuphela ibhande elihambisanayo elingamelana ne-ozone—asiphathisa ukuthula kwengqondo okuza nokukhiqiza okuzinzile. Yilo kanye lo muzwa womthwalo wemfanelo osenze saqashelwa inani elikhulayo lamakhasimende emhlabeni jikelele.

 

Uma umugqa wakho wokukhiqiza nawo uhlushwa ukugqwala kwe-ozone, futhi ukushintshwa njalo kwamabhande esikhathi ajwayelekile kukushiya ukhungathekile, kungani ungaxhumani nathi? Sisebenzisa ubuchwepheshe bethu obuqinisekisiwe bokwenza ngokwezifiso amabhande esikhathi amelana ne-ozone, sizoklama ikhambi lokushayela elifanelana kahle nezimo zakho zokusebenza—ukuqinisekisa ukusebenza kahle kwemishini kanye nenqubo yokukhiqiza engenamthungo.
