Izikhwama zephepha ezenziwe ngokhuni, uhlobo lokupakisha olusetshenziswa kabanzi ezitolo zokuthengisa nezitolo zokudla, seluyinto ethandwayo phakathi kwabathengi abaqaphela imvelo. Kodwa kungani benjaloizikhwama zephepha ze-kraftenobungani nemvelo?
Okokuqala, ake siqale ngencazelo ye-iphepha lokwakha. Iphepha lobucikouhlobo lwephepha elenziwe nge-pulp yamakhemikhali ekhiqizwa yinqubo ye-kraft. Inqubo ye-kraft isebenzisa ama-chips okhuni namakhemikhali ukuphula imicu ekhunini, okuholela ephepheni eliqinile, elihlala isikhathi eside, nelinombala onsundu. Umbala onsundu weiphepha lokwakhakungenxa yokuthi ayishintshiwe, ngokungafani nezinye izinhlobo eziningi zephepha.
Ngakho-ke, kunganiizikhwama zephepha ze-kraftinobungani nemvelo? Nazi izizathu eziningana:
1. Ukubola kwezinto eziphilayo –Izikhwama zephepha ezenziwe ngokhuniziyabola, okusho ukuthi zingabola ngokwemvelo bese zibuyela emhlabeni ngaphandle kokulimaza imvelo. Ngokungafani nezikhwama zepulasitiki, ezingathatha amakhulu eminyaka ukubola,izikhwama zephepha ze-kraft ingaphuka phakathi namasonto ambalwa. Lokhu kunciphisa inani lemfucuza egcina itholakala ezindaweni zokulahla udoti.
2. Imithombo evuselelekayo -Iphepha lobucikoyenziwe ngemicu yokhuni, okuwumthombo ovuselelekayo. Lokhu kusho ukuthi izihlahla zazisetshenziselwa ukwenzaiphepha lokwakhaingatshalwa kabusha, okusiza ekulondolozeni imvelo. Lokhu futhi kwenzaiphepha lokwakha inketho eqhubekayo kakhulu kunezikhwama zepulasitiki, ezenziwe ngamalahle angavuseleleki.
3. Ukusebenziseka Kabusha –Izikhwama zephepha ezenziwe ngokhuninazo zingaphinde zisetshenziswe. Zingahlelwa ngeminye imikhiqizo yephepha bese ziphinde zisetshenziswe zibe imikhiqizo emisha yephepha, njengephephandaba namabhokisi ekhadibhodi. Lokhu kunciphisa inani lemfucuza egcina itholakala ezindaweni zokulahla udoti futhi kusiza ukonga imithombo yemvelo.
4. Ukusetshenziswa kahle kwamandla – Ukukhiqizwaizikhwama zephepha ze-kraft kudinga amandla amancane kunokukhiqizwa kwezikhwama zepulasitiki. Lokhu kungenxa yokuthi inqubo yokukhiqiza izikhwama zepulasitiki ihilela ukusetshenziswa kwamafutha emvelo, adinga amandla amaningi ukukhipha nokucubungula. Izikhwama zephepha ezenziwe ngokhuniNgakolunye uhlangothi, zenziwe ngezinsiza ezivuselelekayo futhi zidinga amandla amancane ukuze zikhiqizwe.
5. Ukwehla kokukhishwa kwamagesi okushisa angaphansi komhlaba – Ukukhiqizwa kweizikhwama zephepha ze-kraftkuholela ekukhiqizweni okuphansi kwegesi ebamba ukushisa kunezikhwama zepulasitiki. Lokhu kungenxa yokuthi inqubo yokukhiqiza izikhwama zepulasitiki ikhipha inani elikhulu lamagesi abamba ukushisa emkhathini, okubangela ushintsho lwesimo sezulu. Ngakolunye uhlangothi, ukukhiqizwa kwezikhwama zephepha ezenziwe ngobuciko kukhiqiza amagesi ambalwa abamba ukushisa, okwenza kube inketho enobungani nemvelo.
Ekuphetheni, izikhwama zephepha ezenziwe nge-kraft zinobungani nemvelo ngezizathu eziningana. Zibola kalula, zenziwe ngezinsiza ezivuselelekayo, ziphinde zisetshenziswe, zisebenza kahle, futhi zikhiqiza ukukhishwa okuncane kwegesi ebamba ukushisa uma kuqhathaniswa nezikhwama zepulasitiki. Lezi zici zenzaizikhwama zephepha ze-kraftukukhetha okuhle kwabathengi abaqaphela imvelo abafuna ukunciphisa umthelela wabo emvelweni. Ngakho-ke, ngesikhathi esizayo lapho usesitolo sokudla, khetha i-isikhwama sephepha le-kraftesikhundleni sesikhwama sepulasitiki futhi uzizwe kahle ngokwenza umthelela omuhle emvelweni.
