Ukusetshenziswa kweipayipi lensimbiakuphephile nje kuphela kubantu, kodwa futhi kuphephile nakwezemvelo. Kodwa kungani sisho kanjalo?
Insimbi Ingasetshenziswa Kabusha Kakhulu
Kuyiqiniso elaziwayo elincane ukuthi insimbi iyinto ephinde isetshenziswe kakhulu emhlabeni. Ngo-2014,86%insimbi yaphinde yasetshenziswa, okwadlula inani lephepha, i-aluminium, ipulasitiki kanye nengilazi. Lokhu kungase kuzwakale kungakholeki, kodwa uma ucabanga ngezinto ezithile ngensimbi ngesikhathi sangempela, kunengqondo ngempela:
Ngokwezibalo ze-Ellen MacArthur Foundation, yi-14% kuphela yepulasitiki emhlabeni ephinde isetshenziswe. Ngokuphambene nalokho, izinga lokubuyiselwa kwephepha emhlabeni wonke lingu-58%, kanti izinga lokubuyiselwa kwensimbi lingu-70% kuya ku-90%. Ngokusobala, izinga lokubuyiselwa kwensimbi liphezulu kakhulu.
Kungani insimbi iba yinto enesilinganiso esiphezulu sokubuyisa? Kunezizathu eziningana eziyinhloko:
1. Uzibuthe wensimbi
Insimbi iyinto esetshenziswa kabusha kalula kakhulu emhlabeni, ikakhulukazi ngenxa yamandla ayo okuzibutha. Amandla okuzibutha enza kube lula ukuthi umshini wokuchoboza uhlukanise insimbi elahliwe, ukuze amabhizinisi okuqaqa izimoto athole inzuzo, ngoba imakethe yokujikeleziswa kwensimbi elahliwe isivuthiwe kakhulu.
2. Insimbi inezakhiwo ezimangalisayo zensimbi
Enye yezinzuzo ezinkulu zensimbi njengento ukuthi ngeke yonakale uma isetshenziswa kabusha. Lokhu kusho ukuthi insimbi esetshenziswa kunoma iyiphi indawo ingancibilikiswa futhi isetshenziswe kusuka komunye umkhiqizo iye komunye ngaphandle kokulahlekelwa ukusebenza kwayo.
3. Izinsizakusebenza eziningi ezilahliwe
Kunemithombo eminingi yensimbi elahliwe, ehlukaniswe ngezigaba ezintathu yimboni:
Imfucuza yasekhaya - Lena yinsimbi etholakale enkambisweni eyenzeka ngaphakathi efektri. Lena inqubo eyamukelwa yizo zonke izimboni zensimbi, ngoba zonke izinto ezilahliwe zisetshenziswa kabusha ngandlela thile.
Izinsalela zasefektri - izinto ezisele ezikhishwe ngama-oda ensimbi enkulu bese zibuyiselwa efektri ukuze ziphinde zisetshenziswe. Imfucuza esheshayo engasetshenziswanga iyancibilika ngokushesha bese yenziwa imikhiqizo emisha.
Imfucuza ephelelwe yisikhathi - lokhu kungavela emikhiqizweni emidala, ezindaweni zokulahla udoti, noma ngisho nasekusetshenzisweni kabusha kwemishini yezempi esiphelelwe yisikhathi. Izigxobo ezine zensimbi zingakhiqizwa ngezinto zemoto elahliwe.
4. Insimbi ephinde yasetshenziswa inezinzuzo zemvelo
Insimbi ephinde yasetshenziswa inezinzuzo zemvelo. Ithani ngalinye lensimbi eqoshiwe esetshenziselwa ukwenza insimbi linganciphisa amathani ayi-1.5 e-carbon dioxide, amathani ayi-14 e-iron ore kanye nama-740 kg amalahle. Njengamanje, sithola amathani angaba yizigidi ezingu-630 ensimbi eqoshiwe minyaka yonke, futhi singanciphisa cishe amathani ayizigidi ezingu-945 e-carbon dioxide minyaka yonke, okungaphezu kuka-85%. Uma kuqhathaniswa nenqubo yendabuko esebenzisa i-iron ore namalahle njengezinto zokusetshenziswa, ukukhiqizwa kwemikhiqizo yensimbi eqoshiwe kudla cishe ingxenye yesithathu yamandla kuphela. I-Scrap nayo iyinto eluhlaza ebalulekile enqubweni yendabuko yokuguqula i-blast furnace. Ukwengeza i-scrap kungamunca amandla amaningi enqubweni yokwenza insimbi yokuguqula futhi kulawule izinga lokushisa lokusabela esithandweni.
Insimbi ingenye yezinto zokuqala zezimboni ezisetshenziswe kabusha
Inqubo ejwayelekile yanoma yisiphi isitshalo sensimbi ukuthola izinsalela ekukhiqizweni kwezingxenye zensimbi. Abakhiqizi sebefunde isikhathi eside ukuthi insimbi ngeke ilahlekelwe amandla uma incibilikiswa futhi isetshenziselwa ezinye izinjongo. Ngisho nokungcola okufana nopende nokugqwala ngeke kuthinte amandla angokwemvelo ensimbi. Ngo-2020, imboni yensimbi izolanda insimbi eyanele ezimotweni ezisetshenzisiwe zodwa ukukhiqiza izimoto ezintsha eziyizigidi ezingu-16. Nakuba amathani amabili kwamathathu ensimbi entsha ekhiqizwa ngezinto ezisetshenziswe kabusha, kusadingeka ukwengeza izinsimbi eziyinhloko kule nqubo. Isizathu ukuthi izimoto eziningi zensimbi nezakhiwo zivame ukuqina kakhulu futhi zinempilo ende yenkonzo, kuyilapho isidingo somhlaba wonke sensimbi siqhubeka nokukhula.
Esikhathini esizayo, sidinga ukuthuthukisa ukusebenza kahle kokusetshenziswa kwezinto ngokuthuthukisa ukwakheka komkhiqizo, inqubo yokukhiqiza, ukuthuthukisa ukusetshenziswa okusimeme kanye nokusetshenziswa kabusha kwemikhiqizo ngabathengi, kanye nokwandisa impilo yesevisi yezinto zokwakha. Ngokuthatha lezi zinyathelo, singakhuthaza intuthuko esimeme yomphakathi.
I-Yuantai Derun Ipayipi LensimbiIthimba liyaziqhenya ngokuthi senza ingxenye yethu yokwenza umhlaba wethu uhlanzeke. Sibeka phambili izinto ezilula ukuzisebenzisa kabusha. Uma siqashwe kuphrojekthi, sibeka phambili izinto ezisetshenziswa kabusha nezingasetshenziswa kabusha.
