Ukusetshenziswa kweithubhu yensimbiakuphephile nje kuphela kubantu, kodwa futhi kuphephile endaweni ezungezile.Kodwa kungani sisho kanjalo?
Insimbi Isebenza Kabusha Kakhulu
Kuyiqiniso elaziwa kancane ukuthi insimbi iyinto egaywa kabusha kakhulu emhlabeni. Ngo-2014,86%yensimbi yaphinde yasetshenziswa, eyeqa isamba sephepha, i-aluminium, ipulasitiki nengilazi. Lokhu kungase kuzwakale kungakholeki, kodwa uma ucabangela ezinye izinto ngensimbi ngesikhathi sangempela, kunengqondo ngempela:
Ngokwezibalo ze-Ellen MacArthur Foundation, i-14% kuphela yepulasitiki emhlabeni esetshenziswa kabusha. Ngokuphambene, izinga lokutholwa kwamaphepha emhlabeni wonke lingama-58%, kanti izinga lokutholwa kwensimbi lingama-70% kuya ku-90%. Ngokusobala, izinga lokutholwa kwensimbi liphezulu kakhulu.
Kungani insimbi iba into enezinga eliphezulu lokululama? Kunezizathu ezimbalwa eziyinhloko:
1. Uzibuthe wensimbi
Insimbi iyinto egaywa kabusha kalula kakhulu emhlabeni, ikakhulukazi ngenxa yemagnetism yayo. I-Magnetism yenza kube lula ukuthi i-crusher ihlukanise izinsimbi ezilahliwe, ukuze amabhizinisi okuhlakazwa kwezimoto athole inzuzo, ngoba imakethe ye-scrap steel circulation ivuthwe kakhulu.
2. Insimbi inezinto ezimangalisayo ze-metallurgical
Enye yezinzuzo ezinkulu zensimbi njengezinto ezibonakalayo ukuthi ngeke zilulaze uma ziphinda zisetshenziswa. Lokhu kusho ukuthi insimbi esetshenziswa kunoma yimuphi umthamo ingancibilika futhi isetshenziswe kusuka komunye umkhiqizo kuya komunye ngaphandle kokulahlekelwa ukusebenza.
3. Izinsiza eziningi ezilahliwe
Kunemithombo eminingi yensimbi eyizinsimbi, ehlukaniswe izigaba ezintathu yimboni:
Imfucuza yasendlini - Lena insimbi etholwe ohlelweni olwenzeka ngaphakathi efektri. Lena inqubo eyamukelwa yizo zonke izitshalo zensimbi, ngoba zonke izinto ezilahlwayo ziphinde zisetshenziswe ngandlela thize.
Izinsalela zasefekthri - impahla eyeqile ekhishwe kuma-oda ensimbi eyinqwaba futhi yabuyiselwa efekthri ukuze igaywe kabusha. Udoti osheshayo ongasetshenzisiwe uyancibilika ngokushesha futhi wenziwa imikhiqizo emisha.
Udoti ophelelwe yisikhathi - lokhu kungase kuvele emikhiqizweni emidala, izindawo zokulahla udoti, noma ngisho nasekusetshenzisweni kabusha kwemishini yezempi engasasebenzi. Izigxobo ezine zensimbi zingakhiqizwa ezintweni zemoto eshiyiwe.
4. Insimbi egaywe kabusha inezinzuzo zemvelo
Insimbi egaywe kabusha inezinzuzo zemvelo. Ithani ngalinye lezinsimbi ezilahliwe ezisetshenziselwa ukwenza insimbi linganciphisa amathani angu-1.5 e-carbon dioxide, amathani angu-14 ensimbi yensimbi kanye nama-740 kg amalahle. Njengamanje, sithola amathani acishe abe yizigidi ezingu-630 ezinsimbi ezilahliwe minyaka yonke, futhi singanciphisa cishe amathani ayizigidi ezingu-945 e-carbon dioxide minyaka yonke, ngaphezu kwama-85%. Uma kuqhathaniswa nenqubo yendabuko kusetshenziswa insimbi yensimbi namalahle njengezinto zokusetshenziswa, ukukhiqizwa kwemikhiqizo yensimbi ephuma emvuleni kudla kuphela ingxenye eyodwa kwezintathu yamandla. I-Scrap iphinde ibe yimpahla ebalulekile enqubweni yokuguqula isithando somlilo esishisayo. Ukwengeza izinsalela kungamunca amandla engeziwe kunqubo yokwenza insimbi yesiguquli futhi kulawule izinga lokushisa lokusabela esithandweni somlilo.
Insimbi ingenye yezinto zasembonini ezigaywe kabusha
Inqubo evamile yanoma yisiphi isitshalo sensimbi ukubuyisela izinsalela ekukhiqizeni izingxenye zensimbi. Sekuyisikhathi eside abakhiqizi befunda ukuthi insimbi ngeke ilahlekelwe amandla lapho isincibilika futhi isetshenziselwa ezinye izinjongo. Ngisho nezinto ezingcolisayo ezinjengopende nokugqwala ngeke kuthinte amandla ensimbi emvelo. Ngo-2020, imboni yensimbi izobuyisa insimbi eyanele ezimotweni ezisetshenzisiwe zizodwa ukukhiqiza izimoto ezintsha eziyizigidi eziyi-16. Nakuba amathani amabili kwamathathu ensimbi entsha ekhiqizwa ezintweni ezigaywe kabusha, kusadingeka ukwengeza izinsimbi eziyinhloko kule nqubo. Isizathu siwukuthi izimoto eziningi zensimbi nezakhiwo ngokuvamile zihlala isikhathi eside futhi zinesevisi ende, kuyilapho isidingo somhlaba wonke sensimbi siqhubeka sikhula.
Ngokuzayo, sidinga ukuthuthukisa ukusetshenziswa kahle kwezinto ngokuthuthukisa ukwakheka komkhiqizo, inqubo yokukhiqiza, ukuthuthukisa ukusetshenziswa okuzinzile nokusetshenziswa kabusha kwemikhiqizo ngabathengi, nokwelula impilo yesevisi yezinto. Ngokuthatha lezi zinyathelo, singakhuthaza intuthuko esimeme yomphakathi.
I-Yuantai Derun Ipayipi LensimbiIthimba liyaziqhenya ngokuthi senza ingxenye yethu ukwenza umhlaba wethu uhlanzeke. Sibeka kuqala izinto ezisetshenziswa kalula. Uma siqashwe kuphrojekthi, sibeka kuqala izinto ezigaywe kabusha nezigaywa kabusha.
