E-SINGAPORE: Unokucinga ukuba ukutshintshela kwiiplastiki ezisetyenziselwa enye ukuya kwiiplastiki ze-biodegradable zilungele imo engqongileyo kodwa eSingapore, "akukho mahluko asebenzayo", iingcali zathi.
Bahlala bephela kwindawo enye - i-incinerator, utshilo uNjingalwazi uTong Yen Wah ovela kwiSebe leMichiza kunye ne-Biomolecular Engineering kwiYunivesithi yeSizwe yaseSingapore (NUS).
Inkunkuma yeplastiki enokubola yenza umahluko kwindalo kuphela xa ingcwatywa kwiindawo zokulahla inkunkuma, wongezelela.
“Kwezi meko, ezi ngxowa zeplastiki zinokonakala ngokukhawuleza xa kuthelekiswa nengxowa yeplastiki eqhelekileyo ye-polyethylene kwaye aziyi kuchaphazela indalo kakhulu.Lilonke eSingapore, kunokuba kubiza ngakumbi ukutshisa iiplastiki ezinokonakala, utshilo u-Assoc uNjingalwazi Tong.Wachaza ukuba oku kungenxa yokuba ezinye iinketho ze-biodegradable zithatha izixhobo ezininzi ukuvelisa, ezenza ukuba zibize kakhulu.
Uluvo lubonisa ukuba uGqr Amy Khor, uMphathiswa oMkhulu weSizwe wezeNdalo kunye neMithombo yaManzi wathi ePalamente ngo-Agasti - ukuba uvavanyo lokujikeleza ubomi beengxowa zokuphatha ezisetyenziselwa enye kunye nezinto ezilahlwayo yi-Arhente yeSizwe yeNdalo (NEA) yafumanisa ukuba ukutshintshwa. iiplastiki ezinolunye uhlobo lwezixhobo zokupakisha ezisetyenziselwa enye "ayiyonto ibhetele kwindalo esingqongileyo".
“ESingapore, inkunkuma iyatshiswa kwaye ayishiywa kwindawo yokulahla inkunkuma ukuba ithobeke.Oku kuthetha ukuba iimfuno zezibonelelo zeengxowa ezinokonakala i-oxo ziyafana nezo zeplastiki, kwaye zinefuthe elifanayo lokusingqongileyo xa zitshiswa.
"Ukongezelela, izikhwama ze-oxo-degradable zingaphazamisa inkqubo yokuphinda isetyenziswe xa ixutywe neeplastiki eziqhelekileyo," kusho uphando lwe-NEA.
Iiplastiki ezonakaliswa yi-Oxo zikhawuleza ziqhekeke zibe ziingceba ezincinci nezincinci, ezibizwa ngokuba zii-microplastics, kodwa aziqhekeki kwinqanaba lemolekyuli okanye i-polymer njengeeplastiki ezinokuguquguquka kunye ne-compostable.
I-microplastics ebangelwayo ishiywe kwindawo engapheliyo de ekugqibeleni iphule ngokupheleleyo.
yena I-European Union (EU) eneneni igqibe ngoMatshi ukuba ivale izinto ezenziwe nge-oxo-degradable plastic ecaleni kokuvalwa kokusetyenziswa kweeplastiki enye.
Ekwenzeni isigqibo, i-EU yathi iplastiki ene-oxo-degradable "ayiyiyo i-biodegrade ngokufanelekileyo kwaye ngaloo ndlela igalelo kungcoliseko lwe-microplastic kwindalo".
