Uphononongo lufumene iibhegi bezisakwazi ukuthwala ivenkile nangona kukho amabango okusingqongileyo
Iingxowa zeplastiki ezibanga ukuba ziyakwazi ukubola bezingekaguquguquki kwaye zikwazi ukuthwala iivenkile kwiminyaka emithathu emva kokuvezwa kwendalo, uphando luye lwafumanisa.
Uphando okokuqala ngqa luvavanye iingxowa ezivundisiweyo, iindlela ezimbini zengxowa enokubola kunye neengxowa eziqhelekileyo zokuthwala emva kokuvezwa ixesha elide elwandle, emoyeni nasemhlabeni.Akukho nanye ingxowa ebole ngokupheleleyo kuyo yonke indawo.
Ibhegi evundisiweyo ibonakala ihamba ngcono kunento ebizwa ngokuba yi-biodegradable bag.Isampulu yengxowa evundisiweyo yanyamalala ngokupheleleyo emva kweenyanga ezintathu kwindawo yaselwandle kodwa abaphandi bathi umsebenzi omninzi uyafuneka ukuze kubonwe ukuba zithini na iimveliso zokonakala kunye nokuqwalasela nayiphi na imiphumo enokubakho kokusingqongileyo.
Emva kweminyaka emithathu iingxowa “ezinokonakala” ezazingcwatywe emhlabeni naselwandle zakwazi ukuthwala iivenkile.Isikhwama somquba sasikhona emhlabeni kwiinyanga ezingama-27 emva kokungcwatywa, kodwa xa ivavanywa ngokuthenga ayikwazanga ukubamba ubunzima ngaphandle kokukrazula.
Abaphandi abavela kwiYunithi yoPhando lweLitha yaseLwandle yeDyunivesithi yasePlymouth bathi olu phononongo - olupapashwe kwijenali yeSayensi yezeNdalo kunye neTekhnoloji - luphakamisa umbuzo wokuba ingaba imixube ye-biodegradable inokuthenjwa na ukuze ibonelele ngesantya esiphezulu ngokwaneleyo sokuthotywa kwaye ke isisombululo esinokwenyani ingxaki yenkunkuma yeplastiki.
U-Imogen Napper, owayekhokela isifundo, wathi:“Emva kweminyaka emithathu, ndamangaliswa ngokwenene ukuba naziphi na iibhegi zisakwazi ukugcina umthwalo wokuthenga.Kuba iingxowa biodegradable ukuba bakwazi ukwenza oko kwakumangalisa kakhulu.Xa ubona into ebhalwe ngolo hlobo, ndicinga ukuba ngokuzenzekelayo ucinga ukuba iya kuthotywa ngokukhawuleza kuneengxowa eziqhelekileyo.Kodwa, emva kweminyaka emithathu ubuncinci, uphando lwethu lubonisa ukuba ayinakuba njalo. ”
Malunga nesiqingatha seeplastiki ziyalahlwa emva kokuba zisetyenziswe kanye kwaye ubuninzi bazo buphela buyinkunkuma.
Ngaphandle kokwaziswa kweentlawulo zeengxowa zeplastiki e-UK, iivenkile ezinkulu zisavelisa iibhiliyoni ngonyaka.Auphando lwezona venkile zininzi zili-10IGreenpeace ibonise ukuba bavelisa iingxowa zeplastiki ezi-1.1bn ezisetyenziswa kanye, i-1.2bn yeplastiki ivelisa iingxowa zeziqhamo kunye nemifuno kunye ne-958m ezisetyenziselwa "iingxowa zobomi" ngonyaka.
Uphononongo lwe-Plymouth luthi kwi-2010 kuqikelelwa ukuba i-98.6bn izikhwama zeplastiki zeplastiki zifakwe kwimarike ye-EU kwaye malunga ne-100bn eyongezelelweyo izikhwama zeplastiki zibekwe minyaka yonke ukususela.
Ukuqonda ingxaki yongcoliseko lweplastiki kunye neempembelelo zokusingqongileyo kukhokelele ekukhuleni koko kubizwa ngokuba yi-biodegradable and compostable options.
Uphando luthi ezinye zezi mveliso zithengiswa ecaleni kweengxelo ezibonisa ukuba "zinokuphinda zisetyenziswe kwindalo ngokukhawuleza ngakumbi kuneplastiki eqhelekileyo" okanye "iindlela ezizezinye ezisekwe kwisityalo kwiplastiki".
Kodwa uNapper uthe iziphumo zibonise ukuba akukho nanye yeengxowa ekunokuthenjwa kuzo ukubonisa nakuphi na ukuwohloka okukhulu kwisithuba seminyaka emithathu kuzo zonke iimeko."Ngoko ke akucaci ukuba i-oxo-biodegradable okanye i-biodegradable formulations ibonelela ngamazinga aphezulu ngokwaneleyo okonakala ukuba ibe luncedo kwimeko yokunciphisa inkunkuma yaselwandle, xa kuthelekiswa neengxowa eziqhelekileyo," uphando lufumene.
Uphando lubonise ukuba indlela ekulahlwa ngayo iingxowa ezivundisiweyo ibalulekile.Kufuneka kuthomalaliswe i-biodegrade kwinkqubo elawulwayo yokwenziwa komgquba ngesenzo sezinto eziphilayo ezincinci ezenzeka ngokwendalo.Kodwa ingxelo yathi oku kufuna umjelo wenkunkuma onikezelwe kwinkunkuma enokuvundiswa - i-UK ayinayo.
I-Vegware, eyavelisa isikhwama somquba esisetyenzisiweyo kuphando, yathi isifundo sisikhumbuzo esifike ngexesha lokuba akukho nto yayiyimilingo, kwaye inokuphinda isetyenziswe kwakhona kwindawo yayo echanekileyo.
“Kubalulekile ukuqonda umahluko phakathi kwamagama afana ne-compostable, biodegradable and (oxo)-degradable,” satsho isithethi.“Ukulahla imveliso kwindawo esingqongileyo kuseyinkunkuma, kuyavundisa okanye ngenye indlela.Ukungcwaba akuvundisi.Izinto ezivundisiweyo zinokuvundisa ngeemeko ezintlanu eziphambili - iintsholongwane, ioksijini, ukufuma, ubushushu kunye nexesha.
Iindidi ezintlanu ezahlukeneyo zengxowa yokuthwala iplastiki ziye zathelekiswa.Ezi zibandakanya iintlobo ezimbini zengxowa ye-oxo-biodegradable, enye i-biodegradable bag, enye i-compostable bag, kunye ne-high-density polyethylene bag-iplastiki eqhelekileyo.
Uphononongo lufumene ukunqongophala kobungqina obucacileyo bokuba i-biodegradable, i-oxo-biodegradable kunye ne-compostable materials inika inzuzo yokusingqongileyo ngaphezu kweeplastiki eziqhelekileyo, kunye nokubanakho ukuhlukana kwi-microplastics kubangele inkxalabo eyongezelelweyo.
UProf Richard Thompson, intloko yeli candelo, uthe uphando luphakamisa imibuzo malunga nokuba uluntu luyalahlekiswa na.
“Sibonisa apha ukuba izinto ezivavanyiweyo azizange zibonise naliphi na ithuba elingaguqukiyo, elithembekileyo nelifanelekileyo kumxholo wenkunkuma yaselwandle,” utshilo.“Iyandixhalabisa into yokuba ezi ncwadi zintsha zikwanika imiceli mngeni ekusetyenzisweni ngokutsha.Uphononongo lwethu lugxininisa imfuneko yemigangatho enxulumene nezinto ezinokonakala, ichaza ngokucacileyo indlela yokulahla efanelekileyo kunye namazinga okuthotywa anokulindeleka.
