Ukufundisisa iingxowa ezifunyenweyo zazikwazi ukuthwala ukuthenga ngaphandle kwamabango engqongileyo
Iingxowa zeplastiki ezithi zibanga ukuba zenziwa zi-biodegrades zisengqiqweni kwaye zikwazi ukuthwala ukuthenga iminyaka emithathu emva kokuba zivezwe kwindalo esingqongileyo, ufundisiso lufumene.
Uphando okokuqala luvavanywe iingxowa ezinobuchopho, iifom ezimbini zengxowa ye-biodegraphid kunye neengxowa eziqhelekileyo zokuthwala emva kokuvezwa kwexesha elide elwandle, umoya nomhlaba. Akukho nanye yeengxowa ezilahlekelwe ngokupheleleyo kuzo zonke iindawo.
Ibhegi ehlanganisiweyo ibonakala ilunge ngakumbi kunengxowa ebizwa ngokuba yi-biodegrady. Isampulu yengxowa ehlanganisiweyo yayiye yanyamalala ngokupheleleyo emva kweenyanga ezintathu kwindawo yaselwandle kodwa abaphandi bathi umsebenzi omninzi uyafuneka ukumisela ukuba zeziphi iimveliso zobuqhetseba kwaye ziqwalasele nayiphi na imiphumo emiselweyo.
Emva kweminyaka emithathu "ze-biodegradiy" ezingcwatyelwe emhlabeni kwaye ulwandle lwalukwazi ukuthwala theya ivenkile. Ingxowa ehlanganisiweyo yayikho emhlabeni kwiinyanga ezingama-27 emva kokungcwatywa, kodwa xa ivavanywa ngokuthenga ayikwazanga ukubamba nabuphi na ubunzima ngaphandle kokukhulisa.
Abaphandi kwiYunivesithi yeYunithi yeLizwe laseRymouth Erine yeLizwe leLizwe lithi uphononongo lweNzululwazi yezeNdalo kunye neTekhnoloji-iphakamisa umbuzo wokuba i-biodegraphles inobuchule kwaye ke isisombululo esifanelekileyo kwi Ingxaki yenkunkuma yeplastiki.
Imogen Napper, eyakhokelela isifundo, yathi:"Emva kweminyaka emithathu, ndamangaliswa kukuba nayiphi na ibhegi enokubamba umthwalo wokuthenga. Kwiingxowa ezixabisekileyo ukuze ukwazi ukwenza le yeyona nto imangalisayo. Xa ubona into ebhalwe ngaloo ndlela, ndicinga ukuba uyacinga ngokuzenzekelayo uza kuphelisa ngokukhawuleza kwiingxowa eziqhelekileyo. Kodwa, emva kweminyaka emithathu ubuncinci, uphando lwethu lubonisa oko kusenokwenzeka ukuba akunjalo. "
Malunga nesiqingatha seplantiki ilahlekile emva kokusetyenziswa okukodwa kunye nesixa esikhulu siphela njengenkunkuma.
Ngaphandle kokungeniswa kweentlawulo zeengxowa zeplastiki e-UK, iivenkile ezinkulu zisavelisa amawaka ezigidi ngonyaka. AUvavanyo lweevenkile ezinkulu ezili-10I-Greenpepeace ityhilwe ukuba babevelisa i-1.1bn Bagn-Bittle-Iplastiki yeplastiki ivelisa iingxowa zediji kunye nemifuno kunye ne-958m "ngonyaka.
Isifundo sePlymouth ithi ngo-2010 sasiqikelelwa ukuba iingxowa zeplastiki zeplastiki zeplastiki zabekwa kwimarike ye-EU kwaye malunga neengxowa zeplastiki ezingama-100bn zibekwe minyaka le.
Ukwazisa ngengxaki yokungcoliseka kweplastiki kunye nefuthe kwindalo kuye kwakhokelela ekukhuleni kwabo babizwa ngokuba kukukhetha okungafunekiyo kunye nezikhundla.
Olu phando luthetha ezinye zezi mveliso zithengiswa ecaleni kwengxelo ezibonisa ukuba zinokuba "ziphinde zibuyiselwe kwakhona kwindalo ngokukhawuleza kuneplastiki eqhelekileyo" okanye "ezizezinye zeplastiki".
Kodwa i-Napper yatsho iziphumo eziboniswe ngaphandle kweengxowa ezinokuthenjwa ukubonisa naluphi na ukonakala kakhulu kwisithuba seminyaka emithathu kuzo zonke iindawo. "Akucaci ke ke ngoko ukuba iifomu ze-Osoedegraphid okanye ze-biodegrada zibonelela ngamaxabiso aphezulu okubola ukuba ziluncedo kwimeko yokunciphisa inkunkuma yaselwandle," uphando olufunyenweyo.
Uphando lubonise ukuba iingxowa zendlela azilahliwe zibalulekile. Bamele bafanele bade ngenkqubo yokuqokelela i-composting ngokusebenzisa isenzo sezinto ezenzeka ngokwendalo. Kodwa ingxelo yatsho le nto ifuna ukunikezelwa kwenkunkuma kwinkunkuma engqokelela-yeyiphi i-UK engabi nayo.
I-Vegure, evelise ingxowa ethe tyaba esetyenziswa kuphando, yatsho ukuba isifundo sisisikhumbuzo sexesha lokuba akukho nto yayiyimilingo, kwaye inokuphinda isebenze kwakhona kwindawo yayo efanelekileyo.
"Kubalulekile ukuba uqonde umahluko phakathi kweMigaqo-ntle, biodegradable kunye (Oqidi) -Khetha i-sthdrion. "Ukulahla imveliso kwimo engqongileyo kusekukuqhekeza, kuyasebenza okanye ngenye indlela. Ukungcwaba akungqubeni. Izixhobo ezihlanganisiweyo zinokubambisa iimeko ezintlanu eziphambili-microbes, ioksijini, ukufudumala kunye nexesha.
Iindidi ezintlanu ezahlukeneyo zebhegi yeplastiki zithelekiswa. Oku kubandakanya iintlobo ezimbini zengxowa ye-Ogodegraphid, ibhegi enye enokuphinda yenziwe, ibhegi enye, kunye nengxowa yePolithylene Polythylene ibhegi - ibhegi eqhelekileyo yeplastiki.
Isifundo safumana ukungabikho kobungqina obucacileyo bokuba izinto eziphilayo, ze-oxo-biodegrady kunye nezinombo zinika amandla okusingqongileyo ngaphezu kweplastiki eziqhelekileyo, kunye nokwahlulwa kwe-microplastics ebangela inkxalabo eyongezelelweyo.
UProf Richard Thompson, entloko yeyunithi, utshilo uphando ophakanyisiweyo malunga nokuba uluntu lulahlekisiwe.
"Sibonisa apha ukuba izinto ezivavanyiweyo azizange ziveze nakuphi na ukubakho, ukuthembeka kunye nokufumana inzuzo kwimeko yenkunkuma yaselwandle, "utshilo. "Kundikhathaza ukuba ezi zixhobo zenoveli zikwakho imiceli mngeni ekusetyenzisweni kwakhona. Isifundo sethu sigxininisa imfuno yemigangatho enxulumene nezinto ezihlaselweyo, echaza ngokucacileyo indlela efanelekileyo yokulahlwa kwamanani afanelekileyo okuba kulindelwe. "
Ixesha lokuposa: I-35 ukuya kwi-2022
