NgoDisemba 7, 2022, imibutho emi-6 yokhuselo lokusingqongileyo, ngokudibeneyo yakhupha "Isiphakamiso sokuvala ukuveliswa kunye nokusetyenziswa kweeplastiki ezinokonakalisa i-oxo", icela iinkampani ukuba ziyeke ukuvelisa nokuthenga iimveliso ezineeplastiki ezinokonakala nge-oxidative, kwaye zingabi sazikhuthaza ngempazamo njengoko. iimveliso eziluhlaza nezilungele ukusingqongileyo, kwaye acebise ukuba amasebe afanelekileyo karhulumente akhuphe imigaqo-nkqubo yokuthintela ukuveliswa, ukuthengiswa nokusetyenziswa kweemveliso zeplastiki ezinokonakala ngeoksijini.
Kweli xesha lezinto eziluncedo neziluncedo, iiplastiki ziye zaba yinxalenye yobomi babantu abaninzi.Iibhokisi zesidlo sasemini, iipakethi ezikhawulezayo, iingxowa zeplastiki zokuthenga... Ezi mveliso zeplastiki ezilahlwayo azizisi nje lula ebantwini, kodwa zibangela umthwalo omkhulu kokusingqongileyo.Yakuba ingalahlwanga kakuhle, inkunkuma yeplastiki iya kuvuza kwimo engqongileyo kwaye ibe “lungcoliseko olumhlophe”.
Njengomlinganiselo obalulekileyo wophuhliso lohlaza lwelizwe lam, uthintelo nolawulo longcoliseko lunikwe ingqwalasela.Ukuphendula ingxaki yongcoliseko lweplastiki, ngoJanuwari ka-2020, iKomishoni yoPhuhliso kunye noHlaziyo lweSizwe kunye neSebe lezendalo kunye nokusiNgqongileyo ngokudibeneyo bakhuphe "Iimbono malunga nokomeleza uLawulo lokuNgcoliseka kwePlastiki", eyaziwa njengowona myalelo ungqongqo wothintelo lweplastiki. " kwimbali.Nangona kunjalo, iimveliso zeplastiki ziye zangena kuzo zonke iinkalo zobomi babantu.Njengenxalenye yeendlela ezizezinye kwiimveliso zeplastiki ezingonakali, igama elithi "iplastiki eyonakaliswayo" livela "Iimbono malunga nokomeleza ngakumbi uLawulo loNgcoliseko lwePlastiki", "iPlastiki yePlastiki yeminyaka emihlanu ye-14 "kwiSicwangciso sokuSebenza sokuLawula ukuNgcoliseka" kunye namanye amaxwebhu, amashishini kunye namashishini nawo sele eqalisile ukutshintsha ukusetyenziswa kweeplastiki ezinokonakala.
Ukuthotywa kwe-oxidative yeeplastiki kubhekiselele ekongezweni kwe-photosensitizers okanye i-oxidation catalysts kwiiplastiki ezingenakonakala (ezifana ne-polyethylene PE) ukukhawulezisa inkqubo yabo yokuthotywa kwiindawo ezikhanyayo okanye ezine-oksijini.Nangona kunjalo, iimveliso eziwohlokayo ziquka iimveliso zendalo ezifana nekharbon diokside kunye namanzi, kunye nezongezo ezifana ne-microplastics kunye ne-plasticizers.Izongezo zingcolisa indawo yendalo, kwaye izifundo ziye zafumanisa ukuba ii-microplastics zinokubakho kwindawo ixesha elide.Ayisiyiyo loo nto kuphela, i-microplastics inokufunxa izinto ezingcolisa indalo, kwaye kunye nokuqokelelana kwexesha elide kunye nokufuduka kwe-runoff kumhlaba ongaphezulu, ekugqibeleni ziya kuthotywa zibe yi-microplastics okanye i-nanoplastics enobukhulu obuncinci, ifudukele kumanzi aphantsi komhlaba, kwaye inokungena emntwini. umzimba.
Kwiminyaka yakutshanje, amazwe amaninzi kunye nemimandla ikuyekile ukujikeleziswa kunye nokusetyenziswa kweeplastiki ezinokonakala nge-oxo.IKhomishini yaseYurophu yapasisa "i-Directive (EU) 2019/904" ngoJuni 2019, evimbela ngokucacileyo zonke iimveliso zeplastiki zokuchithwa kwe-oxidative, kubandakanywa neemveliso zeplastiki ezisetyenziselwa enye, kwaye iphunyezwe ngoJulayi 2021. Umthetho owamkelwe yi-Iceland ngoJulayi 2020 uvimbela ukubekwa kwimarike yeemveliso ezenziwe ngeeplastiki ezinokuthi zithotywe yi-oxidation okanye ebizwa ngokuba yi-oxygen plastiki, kwaye iya kuphunyezwa ngoJulayi 2021. Imimiselo (FOR-2020-12-18-- 3200) evunywe nguMphathiswa weMozulu kunye nokusiNgqongileyo waseNorway ukuba athintele iimveliso zeplastiki ezinokonakalisa i-oxo kunye neemveliso ezithile zeplastiki ezilahlwayo zakhutshwa ngoJanuwari 2021 kwaye zaqala ukusebenza ngoJulayi waloo nyaka.
NgoDisemba ka-2020, i-Hainan iphumeze ngokusesikweni “iMimiselo yoThintelo lweeMveliso zePlastiki eziLahliweyo ezingaboliyo kwiNdawo yoQoqosho eKhethekileyo yaseHainan”.Iiplastiki kunye neeplastiki ze-thermo-oxo-degradable ziqulethe izinto ezinjalo zeplastiki eziqhelekileyo.Oku kuthetha ukuba iiplastiki ezonakaliswe nge-oxidative azisavunyelwa ukuba zisetyenziswe kwiPhondo laseHainan, kwaye i-Hainan ibe liphondo lokuqala kweli lizwe ukuphumeza ukuvalwa kweplastiki yehlabathi jikelele (kubandakanywa neeplastiki ezichithwa nge-oxidatively).
Inyathelo lokuqala likaHainan lokuthintela ukonakaliswa kwe-oxidative yeeplastiki linike ithuba ii-arhente ezininzi zokhuseleko lokusingqongileyo.Bechatshazelwa koku, ii-arhente ezintandathu zokhuselo lokusingqongileyo uqalise inyathelo "ngokuthintela ukuveliswa kunye nokusetyenziswa iiplastiki oxidatively degradable", ebiza abanye oorhulumente basekhaya e China ukuba babhekisele kuqheliselo Hainan, bajongane phezulu kwaye icacise ingxaki iiplastiki oxidatively degradable, kwaye phelisa impembelelo yeeplastiki ezinokonakala nge-oxidatively kwilizwe lethu ngokukhawuleza.Ubungozi kwindalo kunye nempilo.
No iiplastiki ze-oxo-zonakele, sikhusele isijikelezi-langa sethu.
Yiza kuWorldChamp Enterprises, yakhoUmthengisi weemveliso ze-ECO, Uvulindlela ophakamisa, ukuvelisa, kunye nokusebenzisa iimveliso eziluhlaza ezithatha indawo yeplastiki izinto zemveli, kuqukaiiglavu ezivundisiweyo nezinokubola, ibhegi yokuphuma, ibhegi yokuposa, ibhegi yokuthenga, ingxowa yenkunkuma, ibhegi yenja, ifaskoti, njl.
