Iglasi okanye iplastiki: Yeyiphi eNgcono kuBume beNdawo?

Iglasi okanye iplastiki, yeyiphi eyona nto ingcono kwindawo esihlala kuyo?Ewe, siza kuchaza iglasi vs iplastiki ukuze wenze isigqibo esinolwazi malunga nokuba yeyiphi na oza kuyisebenzisa.

Ayiyomfihlo into yokuba zininzi iifektri ezenza iibhotile zeglasi ezintsha, iingqayi, nokunye okuninzi yonke imihla.Ukongeza, kukho iifektri ezininzi ezenza iplastiki nazo.Siza kukucalula kwaye siphendule imibuzo yakho njengokuba iglasi ingaphinda isetyenziswe, iglasi iyabolisa, kwaye iplastiki bubutyebi bendalo.

Iglasi vs iPlastiki

Xa ujonga inkunkuma eyizero, kuya kufuneka ubone iitoni kunye neetoni zemifanekiso yeengqayi zeglasi kuyo yonke indawo.Ukusuka kwingqayi yenkunkuma ukuya kwiingqayi ezinxibe iipantries zethu, iglasi ithandwa kakhulu kwindawo yenkunkuma eyi-zero.

Kodwa yintoni ukuthanda kwethu iglasi?Ngaba ngokwenene ingcono kakhulu kokusingqongileyo kuneplastiki?Ngaba iglasi iyabola okanye i-eco-friendly?

Iplastiki ithande ukufumana impendulo embi kakhulu kwiingcali zokusingqongileyo - loo nto inento eninzi yokwenza nenyani kuphela i-9 pesenti yayo ephinda isetyenziswe.Oko kuthethiweyo, kuninzi kakhulu onokucinga ngako malunga nento engena kwimveliso kunye nokuhlaziya zombini iglasi kunye neplastiki, singasathethi ke emva kokufa.

Loluphi olona khetho lolona lulungele imeko-bume xa ufika ezantsi kuyo, iglasi okanye iplastiki?Ewe, mhlawumbi impendulo ayicacanga njengoko unokucinga.Ngaba iglasi okanye iplastiki ihambelana nokusingqongileyo?

Iglasi:

Masiqale ngokuhlalutya zonke izinto ezithandekayo ze-zero waster: Iglasi.Okokuqala, kubalulekile ukuba uqaphele ukuba iglasiiyarisayikilishwa ngokungenasiphelo, ibuyele kusetyenziso lwayo lokuqala.

Ayisoze iphulukane nobulunga kunye nokusulungeka kwayo, nokuba ihlaziywa kangaphi kwakhona….kodwa ngaba ngokwenene iyarisayikilishwa?

Inyaniso ngeglasi

Okokuqala, ukwenza iglasi entsha kufuna isanti.Ngelixa sinesanti eninzi elunxwemeni, kwintlango, naphantsi kolwandle, siyisebenzisa ngokukhawuleza kunokuba iplanethi inokuphinda iyizalise.

Sisebenzisa isanti ngaphezu kokuba sisebenzisa i-oyile, kwaye luhlobo oluthile lwesanti kuphela olunokusetyenziswa ukwenza umsebenzi wenziwe (hayi, intlabathi yasentlango ayinakusetyenziswa).Nantsi eminye malunga nemiba:

• Ubukhulu becala, isanti ivunwa emilanjeni naselwandle.
• Ukukhupha isanti kwindawo yendalo kwakhona kuphazamisa i-ecosystem, kuthathelwa ingqalelo ii-microorganisms ezihlala kuyo ezondla isiseko sekhonkco lokutya.
• Ukususa intlabathi emazantsi olwandle kushiya uluntu oluselunxwemeni luvuleleke kwizikhukula kunye nokhukuliseko.

Kuba sifuna isanti ukwenza iglasi entsha, unokubona apho inokuba ngumba.

Iingxaki ezininzi ngeglasi

Enye ingxaki ngeglasi?Iglasi inzima kuneplastiki, kwaye yophuka lula kakhulu ngexesha lokuhamba.

Oku kuthetha ukuba ivelisa izinto ezikhutshwayo ezininzi kwezothutho kuneplastiki kwaye ibiza imali eninzi ukuyithutha.

Ngaba iglasi inokuphinda isetyenziswe?

Enye into ekufuneka uyiqwalaseleiglasi eninzi ayiphinda isetyenziswe.Enyanisweni, yi-33 ekhulwini kuphela yeglasi yenkunkuma ephinda isetyenziswe eMelika.

Xa ucinga nge-10 lezigidi zeetoni zeglasi ezilahlwayo minyaka le eMelika, ayilozinga eliphezulu kakhulu lokurisayikilisha.Kodwa kutheni ukurisayikilisha kuphantsi kangaka?Nazi izizathu ezimbalwa:

• Zininzi izizathu zokuba ukurisayikilisha kweglasi kuphantsi kakhulu: Iglasi efakwa kumgqomo wokurisayikilisha isetyenziswa njengendawo yokuvala inkunkuma ephantsi ukugcina iindleko ziphantsi.
• Abathengi abathatha inxaxheba “kwibhayisekile enqwenelekayo” apho baphosa izinto ezingaphinde zisetyenziswe kumgqomo wokurisayikilisha kwaye bangcolise umgqomo wonke.
• Iglasi enemibala inokuphinda isetyenziswe kwaye inyibilikiswe ngemibala efana neyo.
• IiWindows kunye nePyrex bakeware azikwazi ukuphinda zisetyenziswe ngenxa yendlela eyenziwe ngayo ukumelana nobushushu obuphezulu.

Ngaba iglasi iyabola?

Okokugqibela, iglasi ithatha iminyaka esisigidi ukubola kwimekobume, mhlawumbi nangakumbi kwindawo yokulahla inkunkuma.

Lilonke, loo nto imalunga neengxaki ezine ezinkulu zeglasi ezichaphazela okusingqongileyo.

Ngoku, makhe sihlalutye umjikelo wobomi beglasi ngokusondeleyo.

Yenziwa njani iglasi:

Iglasi yenziwe ngazo zonke izinto zendalo, ezifana nesanti, uthuthu lwesoda, ilimestone kunye neglasi esetyenzisiweyo.

Nangona kunjalo, kubalulekile ukuqaphela ukuba siphelelwa yintlabathi esetyenziselwa ukwenza iglasi kwasekuqaleni.

Ehlabathini lonke, siyadlula5I-0 yeebhiliyoni zeetoni zesanti minyaka le.Eso sisixa esiphindwe kabini kunomlinganiselo oveliswa yiyo yonke imilambo esehlabathini.

Nje ukuba zivuniwe ezi zinto zikrwada, zithuthwa zisiwe kwindlu yebhetshi apho ziye kuhlolwa khona emva koko zithunyelwe kwiziko ukuze zinyibilike, apho zifudunyezwa kwi-2600 ukuya kwi-2800 degrees Fahrenheit.

Emva koko, bahamba ngokulungelelanisa, ukubumba, kunye nenkqubo yokugqiba ngaphambi kokuba babe yimveliso yokugqibela.

Nje ukuba imveliso yokugqibela yenziwe, iyathuthwa ukuze ihlanjwe kwaye ivalwe, emva koko ithuthwe kwakhona ezivenkileni ukuze ithengiswe okanye isetyenziswe.

Nje ukuba ifikelele esiphelweni sayo sobomi, (ngethemba) iyaqokelelwa kwaye isetyenziswe kwakhona.

Ngelishwa, nyaka ngamnye kuphela isinye esithathwini se-10 yezigidi zeetoni zeglasi ezilahlwa ngabantu baseMelika zihlaziywa.

Intsalela iya kwindawo yokulahla inkunkuma.

Xa iglasi iqokelelwa kwaye ihlaziywa, kufuneka iqalise le nkqubo yokuhanjiswa, ukuhamba ngokulungiswa kwebhetshi, nayo yonke enye into elandelayo kwakhona.

Izinto ezikhutshwayo + amandla:

Njengoko unokucinga, yonke le nkqubo yokwenza iglasi, ngakumbi ukusebenzisa izinto ezinyulu, ithatha ixesha elininzi, amandla kunye nezibonelelo.

Kwakhona, isixa sokuthutha iglasi kufuneka sihambe sidibanisa, kwakhona, ukudala ukukhutshwa okungaphezulu kwexesha elide.

Uninzi lweziko ezisetyenziselwa ukwenza iglasi zikwasebenza kumafutha efosili, ngaloo ndlela kudala ungcoliseko oluninzi.

Amandla efosili ewonke asetyenziselwe ukwenza iglasi eMntla Melika, imfuno yamandla engundoqo (PED), eqikelelwa kwi-16.6 megajoule(MJ) ngekhilogram e-1 (kg) yeglasi eveliswayo.

Amandla okufudumala kwehlabathi (GWP), inguqu yemozulu, i-avareji ukuya kwi-1.25 MJ nge-1 kg yeglasi yeglasi eveliswayo.

La manani aquka onke amanqanaba omjikelezo wobomi bokupakishwa kweglasi.

Ukuba uyazibuza, i-megajoule (MJ) yiyunithi yamandla elingana nesigidi seejoules.

Ukusetyenziswa kwegesi yendawo kulinganiswa ngeemegajoules kwaye irekhodwa kusetyenziswa imitha yegesi.

Ukubeka imilinganiselo yekhabhoni yonyawo endiyinike imbono ngcono kancinci, ilitha enye yepetroli ilingana ne 34.8 megajoules, Ixabiso lokufudumeza okuPhezulu (HHV).

Ngamanye amazwi, kuthatha ngaphantsi kwe ilitha yepetroli ukwenza i-1 kg yeglasi.

Amaxabiso okurisayikilisha:

Ukuba indawo yokuvelisa iglasi isebenzise i-50 yepesenti ehlaziyiweyo umxholo ukwenza iglasi entsha, kuya kubakho ukuhla kwe-10 ekhulwini kwi-GWP.

Ngamanye amazwi, i-50 yepesenti yezinga lokuphinda isetyenziswe iyakususa i-2.2 yezigidi zeetoni ze-CO2 kwindalo.

Oko kufana nokususa ukukhutshwa kweCO2 kwiimoto eziphantse zibe ngama-400,000 ngonyaka.

Nangona kunjalo, oku kuya kwenzeka kuphela kucingelwa ukuba ubuncinci be-50 yepesenti yeglasi yahlaziywa ngokufanelekileyo kwaye isetyenziselwa ukwenza iglasi entsha.

Okwangoku, yi-40 yepesenti kuphela yeglasi ephoswe kwingqokelela yohlobo olunye lokurisayikilishwa eneneni ephinda isetyenziswe.

Ngelixa iglasi iphinda isetyenziswe ngokupheleleyo, ngelishwa, kukho izibonelelo ezithile ezikhetha ukutyumza iglasi kwaye ziyisebenzise njengendawo yokugubungela itiphu endaweni yoko.

Oku kunexabiso eliphantsi kunokuhlaziya iglasi, okanye ukufumana enye imathiriyeli yokugquma yokulahla inkunkuma.Izinto ezigqunyiweyo zeendawo zokulahla inkunkuma zingumxube wezinto eziphilayo, ezingaphiliyo nezingasebenziyo (ezifana neglasi).

Iglasi njengokhuselo lwetiphu?

Izigqubuthelo zokulahla inkunkuma zisetyenziselwa ukulawula amavumba akhubekisayo ezitiphu, ukunqanda izitshabalalisi, ukunqanda imililo yenkunkuma, ukunqanda ukugqogqa, kunye nokunciphisa ukubaleka kwamanzi emvula.

Ngelishwa, ukusebenzisa iglasi ukugquma iindawo zokulahla inkunkuma akuncedi okusingqongileyo okanye kuncitshiswe ukukhutshwa kwezinto ezikhutshwayo kuba oko kuthoba iglasi yebhayisekile kwaye iyayinqanda ukuba ingaphinda isetyenziswe.

Qinisekisa ukuba ujonga kwimithetho yendawo yakho yokurisayikilisha phambi kokuba uphinde uyisebenzise iglasi, ukuyijonga nje kabini ukuba iyakuphinda isetyenziswe.

Ukurisayikilisha kweglasi yinkqubo evaliweyo, ngoko ayenzi nayiphi na inkunkuma eyongezelelweyo okanye imveliso.

Isiphelo sobomi:

Ungcono ukuba ubambelele kwiglasi kwaye uyibuyisele kwakhona ngaphambi kokuba uyiphose kumgqomo wokurisayikilisha.Nazi izizathu ezimbalwa zokuba:

• Iglasi ithatha ixesha elide kakhulu ukudilika.Ngapha koko, kungathatha ibhotile yeglasi iminyaka esisigidi ukubola kokusingqongileyo, nangakumbi ukuba ikwindawo yokulahla inkunkuma.
• Kuba umjikelo wobomi bayo mde kakhulu, kwaye ngenxa yokuba iglasi ayivuzi naziphi na iikhemikhali, kungcono ukuphinda uyisebenzise kwaye uyisebenzise ngokuphindaphindiweyo phambi kokuba isetyenziswe kwakhona.
• Ngenxa yokuba iglasi ingenaziphene kwaye ayinamanzi, akukho nxibelelwano phakathi kokupakishwa kweglasi kunye neemveliso ngaphakathi, okukhokelela ekubeni kungabikho mbi emva kwencasa.
• Ngaphezu koko, iglasi inomlinganiselo ophantse ube ngu-zero wokudityaniswa kweekhemikhali, oqinisekisa ukuba iimveliso ezingaphakathi kwibhotile yeglasi zigcina incasa yazo, amandla kunye nevumba.

Ndicinga ukuba yiyo loo nto uninzi lwenkunkuma eyi-zero ikhuthaza abantu ukuba bagcine zonke iingqayi zabo ezingenanto ukuze ziphinde zisetyenziswe.

Kukulungele ukugcina ukutya okufumana kwivenkile yokutya okuninzi, okushiyekileyo, kunye neemveliso zokucoca ezenziwe ekhaya.
