Kwiminyaka yakutshanje, ukuzinza kuye kwaba yingqwalasela ebalulekileyo kubathengi nakumashishini ngokufanayo. Ngokukhula kwenkxalabo malunga nongcoliseko lweplastiki, iingxowa ze-polyethylene (PE) ziye zahlolwa. Kweli nqaku, siza kuphonononga ukusebenzelana kwendalo kweengxowa ze-PE, ifuthe lazo lokusingqongileyo, kunye nokuba zinokuthathwa njengokhetho oluzinzileyo.
Yintoni i-PE Bag?
Iingxowa ze-PE zenziwe nge-polyethylene, eyona plastiki isetyenziswa kakhulu kwihlabathi jikelele. Ziyaziwa ngokuqina kwazo, ukuguquguquka, kunye nokuxhathisa ukufuma, nto leyo eyenza ukuba zidume ekupakisheni, ekuthengeni nasekugcineni. Iingxowa ze-PE ziza ngeendlela ezahlukeneyo, kubandakanya iibhegi ze-ziplock, iibhegi zegrosari, kunye nemathiriyeli yokupakisha, kwaye zithandwa ngenxa yeendleko zazo kunye nokulula kwazo.
Impembelelo yokusiNgqongileyo yeengxowa zePE
Impembelelo yokusingqongileyo yeengxowa ze-PE iqala ngemveliso yazo. I-Polyethylene ivela kumafutha e-fossil angahlaziyekiyo, ngokukodwa ioli ekrwada okanye igesi yendalo. Inkqubo yokuvelisa isebenzisa amandla abalulekileyo kwaye ibangele ukukhutshwa kwekhabhoni, igalelo ekufudumeni kwehlabathi. Nangona kunjalo, iingxowa ze-PE zikhaphukhaphu kwaye zifuna imathiriyeli encinci kunezinye iindlela ezininzi, ukunciphisa ukusetyenziswa kwamandla xa kuthelekiswa nokuqina, iimveliso ezinzima njengeengxowa zephepha okanye iingxowa zelaphu eziphinda zisetyenziswe.
Inqanaba lokubola kunye neMpembelelo ye-Ecosystem
Enye yezona zinto ziphambili ezixhalabisayo ngeengxowa ze-PE kukuphila ixesha elide kokusingqongileyo. Iingxowa ze-PE aziboli ngokukhawuleza; kwiindawo zokulahla inkunkuma, zinokuthatha amakhulu eminyaka ukuba ziqhekeke ngenxa yokungabikho kokukhanya kwelanga kunye neoksijini. Kwiindawo zendalo, ezinje ngeelwandle namahlathi, zinokuqhekeka zibe yi<em>microplastics, zibeka isongelo kwizilwanyana zasendle ezinokuginya okanye zibhijelwe zizinto. Oku kuthotywa kancinci komgangatho kunegalelo kungcoliseko lweplastiki, nto leyo engumba omkhulu wokusingqongileyo.
Ukurisayiklishwa kwakhona kweengxowa zePE
Iingxowa ze-PE ziyakwazi ukuphinda zisetyenziswe, kodwa izinga lokuphinda lisetyenziswe lisezantsi xa lithelekiswa nezinye izinto. Uninzi lweenkqubo zokurisayikilishwa ezisecaleni kwendlela azamkeli iingxowa zePE ngenxa yokuthanda ukuvala oomatshini bokuhlela. Nangona kunjalo, iivenkile ezininzi kunye namaziko okurisayikilisha akhethekileyo ayazamkela ezi ngxowa ukuze zisetyenziswe kwakhona, apho zinokuphinda zisetyenziswe kwiimveliso zeplastiki ezintsha ezifana namaplanga adibeneyo okanye iingxowa ezintsha. Ukwandiswa kolwazi kunye nophuculo kwiziseko ezingundoqo zokurisayikilisha kunokunciphisa kakhulu umthwalo wokusingqongileyo weengxowa zePE.
Iingxowa zePE zithelekiseka njani nezinye iibhegi?
Xa kuthelekiswa impembelelo yokusingqongileyo yeengxowa ze-PE kwezinye iindlela ezifana nephepha okanye ezinye iintlobo zeplastiki, iziphumo zixutywe. Iingxowa zephepha, ngelixa zibola, zifuna amandla amaninzi kunye namanzi ukuvelisa. Uphononongo lubonisa ukuba iingxowa zephepha zinendawo ephezulu yekhabhoni ngenxa yemithombo efunekayo yokulima imithi, ukuvelisa, kunye nokuthutha. Kwelinye icala, iingxowa zeplastiki ezityebileyo ezinokusetyenziswa kwakhona (ezihlala zenziwe ngepolypropylene) kunye neengxowa zelaphu zifuna ukusetyenziswa okuninzi ukuphelisa iimpembelelo zazo eziphezulu zemveliso. Iingxowa ze-PE, ngaphandle kokuhla kwazo, zinendawo encinci yokuqala kodwa azikho njenge-eco-friendly ukuba ziphelela kwindawo endaweni yokuba ziphinde zisetyenziswe.
Uphando kunye neeNkcukacha-manani
Uphononongo luka-2018 olwenziwa yi-Danish Ministry of Environment and Food luqhathanise uvavanyo lomjikelo wobomi beentlobo ezahlukeneyo zeengxowa zokuthenga. Ifumanise ukuba iingxowa ze-PE zineempembelelo zokusingqongileyo ezisezantsi ngokwemiqathango yokusetyenziswa kwamanzi, ukusetyenziswa kwamandla, kunye nokukhutshwa kwegesi ye-greenhouse xa ziphinda zisetyenziswa ngamaxesha amaninzi okanye ziphinda zisetyenziswe. Nangona kunjalo, uphando luye lwabonisa ukubaluleka kokulahlwa okufanelekileyo ukunciphisa umngcipheko wongcoliseko. Le datha iphakamisa ukuba ngelixa iingxowa ze-PE zingekho ngokupheleleyo ngaphandle kweendleko zokusingqongileyo, zinokuba lukhetho oluzinzileyo kunezinye iimeko kwiimeko ezithile, ngakumbi xa ziphinda zisetyenziswe.
Ukuqukumbela
Iingxowa ze-PE, njengayo nayiphi na imveliso yeplastiki, zineenzuzo kunye neengxaki zokusingqongileyo. Iindleko zabo eziphantsi zemveliso, ukusetyenzwa kwakhona, kunye nokuguquguquka kwezinto ezininzi kubenza babe luncedo, kodwa ixesha labo elide lokubola kunye negalelo elinokubakho kungcoliseko lweplastiki yinkxalabo ebalulekileyo. Ngokunyusa amaxabiso okurisayikilishwa, ukukhuthaza ukulahlwa okunoxanduva, kunye nokukhetha ezinye iindlela ezilungele i-eco-friendly apho kunokwenzeka, abathengi banokunceda ukunciphisa impembelelo yokusingqongileyo yeengxowa ze-PE. Njengayo nayiphi na imathiriyeli, isitshixo sozinzo silele ekuqondeni umjikelo wobomi obupheleleyo kunye nokwenza izigqibo ezizizo.
Ukufumana ulwazi oluthe kratya malunga neempembelelo zokusingqongileyo zeplastiki kunye nendlela yokunciphisa inkunkuma yeplastiki, qwalasela izibonelelo zokufunda ezivela kwiI-Arhente yoKhuseleko lweNdalo.
