Nigute ushobora kumenya niba ibikoresho ari biodegradable?Ibipimo bitatu bigomba kurebwa: igipimo cyo gutesha agaciro ugereranije, ibicuruzwa byanyuma nibirimo ibyuma biremereye.Imwe murimwe ntabwo yujuje ubuziranenge, ntabwo rero ari tekiniki ya biodegradable.
Kugeza ubu, hari ubwoko bubiri bwingenzi bwa plastike yangiritse: gusimbuza ibitekerezo nibisigara nyuma yo kubora.Impamvu nyamukuru yo gukora umubare munini wibikoresho bya plastiki byangirika ni uko politiki yo kugabanya plastike yatumye ubwiyongere bukabije bw’imbere mu gihugu bukenera plastiki zangirika.Kugeza ubu, "kubuza plastike" birabujijwe rwose ku byatsi bya pulasitike, kandi ubushobozi bwangirika mu gihugu bushobora gutwikirwa.Mu bihe biri imbere, ibikoresho byangirika bizagenda byuzuzwa buhoro buhoro kandi bikoreshwe ku bikoresho byose byokurya, kandi isano iri hagati yo gutanga nibisabwa igomba guhuzwa buhoro buhoro, ariko ibipimo nubugenzuzi birabura.Ufatanije nigiciro kinini cyibikoresho byangirika, ubucuruzi butwarwa ninyungu, ubushobozi bwo kumenyekanisha abaguzi ni ntege, bikaviramo guteshwa agaciro.
1. Igitekerezo cya plastiki idashobora kwangirika cyahinduwe
Plastiki gakondo hamwe ninyongeramusaruro zinyuranye cyangwa plastike ya biobase ivangwa hamwe, kandi igitekerezo cy "ibikoresho byo mu rwego rwibiryo" n "ibicuruzwa byo kurengera ibidukikije" bisimburwa.Igipimo nyacyo cyo kwangirika kiri hasi mumpera, itujuje ibyangombwa byibicuruzwa byangirika nubuziranenge bwibinyabuzima.
Wu Yufeng, umwarimu mu kigo cy’ubukungu bw’umuzingi muri kaminuza y’ikoranabuhanga ya Beijing, mu kiganiro yagiranye na Consumption Daily yavuze ko “urwego rw’ibiribwa” ari igipimo cy’igihugu gusa ku mutekano w’ibikoresho fatizo, atari icyemezo cy’ibidukikije.Ati: “Iyo tuvuze kuri 'plastiki y’ibinyabuzima,' tuba dushaka kuvuga plastiki, mu bihe bimwe na bimwe, amaherezo igacika burundu muri dioxyde de carbone cyangwa metani, amazi n’ibindi binyabuzima.Mubyukuri, ariko, byinshi bita 'biodegradable plastique' nibikoresho bivangavanga bihuza plastiki zisanzwe hamwe ninyongeramusaruro zitandukanye cyangwa plastike ya biobase.Byongeye kandi, ibicuruzwa bimwe na bimwe bya pulasitiki ndetse bikoresha ibikoresho fatizo bya pulasitiki bitangirika nka polyethylene, byongeramo imiti igabanya ubukana bwa okiside, umukozi w’amafoto, avuga ko 'byangiritse', bivuze ko isoko, bihungabanya isoko. ”
2. Ibisigisigi nyuma yo kubora
Ongeraho igipimo runaka cya krahisi, binyuze mumiterere yumubiri wibikoresho byangirika bisenyuka, PE, PP, PVC, nibindi byangirika ntibishobora kwinjizwa nibidukikije gusa, ariko kuberako bitagaragara kumaso bizahora biguma mubidukikije , ntabwo bifasha gusa gutunganya plastike no kuyisukura, gucamo ibice bya plastike bizangiza byinshi kubidukikije.
Kurugero, D2W na D2W1 ninyongera ya okiside ya biodegradation.Umufuka wa plastiki wakozwe na PE-D2W na (PE-HD) -D2W1 ni imifuka ya pulasitike ya biodegraside ya okiside ya okiside, nk'uko byatangajwe na Liu Jun, umuyobozi w'ikigo cya Shanghai Institute of Quality Supervision and Inspection Technology akaba na injeniyeri mukuru ku rwego rwa mwarimu, mu kiganiro na Beijing. Amakuru.Harimo mubyiciro bya GB / T 20197-2006 byashyizwe mubikorwa bya plastiki yangirika.Ariko inzira yo gutesha agaciro plastike nkiyi nini nini iba nto hanyuma ntoya igacika, ikabihindura microplastique itagaragara.
