(1) Kev txwv yas
Hauv Suav teb,
Los ntawm 2022, kev noj cov khoom siv yas pov tseg yuav raug txo kom tsawg, lwm yam khoom yuav raug txhawb, thiab feem ntau ntawm cov pov tseg yas siv los ua cov peev txheej thiab lub zog yuav nce ntxiv.
Los ntawm 2025, ib qho kev tswj hwm rau kev tsim khoom, kev ncig, kev noj, kev rov ua dua thiab pov tseg cov khoom yas yuav tau tsim, cov khoom pov tseg yas hauv cov chaw pov tseg hauv cov nroog tseem ceeb yuav txo qis, thiab cov pa phem yuav raug tswj tau zoo.
Hauv Suav teb-Lub Plaub Hlis 10, 2020, Heilongjiang xeev tau pib tawm tswv yim txog kev faib cov qauv ntawm cov khib nyiab hauv nroog.
Ntawm A
1. Kev degradation
Kev cuam tshuam los ntawm ib puag ncig ib puag ncig, tom qab qee lub sijhawm thiab koom nrog ib lossis ntau cov kauj ruam, cov qauv tau txais kev hloov pauv tseem ceeb thiab kev ua haujlwm tsis zoo (xws li kev ncaj ncees, txheeb ze molecular loj, qauv lossis lub zog txhua yam).
2. Biodegradation
Kev puas tsuaj tshwm sim los ntawm kev ua haujlwm lom neeg, tshwj xeeb tshaj yog kev ua ntawm enzymes, ua rau muaj kev hloov pauv tseem ceeb hauv cov qauv tshuaj ntawm cov khoom.
Raws li cov khoom yog maj mam decomposed los ntawm cov kab mob los yog tej yam kab mob raws li ib tug nutrient qhov chaw, nws ua rau tsis zoo, kev ua tau zoo, xws li lub cev kev ua tau zoo poob, thiab nws thiaj li ua rau cov ntaub ntawv decomposed mus rau hauv yooj yim compounds los yog cov khoom, xws li carbon dioxide (CO2). ) los yog methane (CH4), dej (H2O) thiab mineralized inorganic ntsev ntawm cov khoom muaj nyob rau hauv, thiab tshiab biomass.
3. Qhov kawg aerobic biodegradation
Nyob rau hauv aerobic tej yam kev mob, cov khoom yog thaum kawg decomposed los ntawm cov kab mob mus rau hauv carbon dioxide (CO2), dej (H2O) thiab mineralized inorganic ntsev ntawm lub ntsiab muaj nyob rau hauv, thiab tshiab biomass.
4.Qhov kawg anaerobic biodegradation
Nyob rau hauv cov xwm txheej anoxic, cov khoom yog thaum kawg decomposed los ntawm cov kab mob mus rau carbon dioxide (CO2), methane (CH4), dej (H2O) thiab mineralized inorganic ntsev ntawm cov ntsiab lus muaj nyob rau hauv thiab tshiab biomass.
5.Biological treatment peev-biological treatability (biological treatability)
Lub peev xwm ntawm cov khoom yuav tsum tau composted nyob rau hauv aerobic tej yam kev mob los yog biologically digested nyob rau hauv anaerobic tej yam kev mob.
6. Deterioration-deterioration (deterioration)
Ib qho kev hloov pauv mus tas li hauv kev poob ntawm cov khoom siv lub cev uas pom los ntawm cov yas vim kev puas tsuaj rau qee cov qauv.
7. Kev tsis sib haum xeeb
Cov khoom siv lub cev tawg mus rau hauv cov khoom zoo heev.
8. Compost (zeeg)
Organic av txias tau los ntawm kev lom decomposition ntawm cov sib tov. Qhov sib tov yog tsim los ntawm cov nroj tsuag residues, thiab qee zaum kuj muaj qee cov khoom siv organic thiab qee yam tshuaj inorganic.
9. Composting
Ib txoj kev kho aerobic los tsim compost.
10.Compostability-compostability
Lub peev xwm ntawm cov ntaub ntawv yuav biodegraded thaum lub sij hawm composting txheej txheem.
Yog hais tias lub peev xwm compost tau tshaj tawm, nws yuav tsum tau hais tias cov khoom yog biodegradable thiab disintegraable nyob rau hauv lub composting system (raws li qhia nyob rau hauv tus qauv xeem txoj kev), thiab yog kiag li biodegradable nyob rau hauv lub kawg siv ntawm compost. Compost yuav tsum ua kom tau raws li cov qauv zoo, xws li cov ntsiab lus ntawm cov hlau hnyav, tsis muaj tshuaj lom lom neeg, thiab tsis muaj qhov sib txawv ntawm qhov seem.
11.Degradable yas (degradable yas)
Raws li cov xwm txheej ib puag ncig, tom qab lub sijhawm thiab muaj ib lossis ntau cov kauj ruam, cov qauv tshuaj ntawm cov khoom raug hloov pauv thiab qee yam khoom (xws li kev ncaj ncees, molecular mass, qauv lossis lub zog txhua yam) ploj thiab / lossis cov yas. tawg. Cov txheej txheem xeem uas tuaj yeem cuam tshuam txog kev hloov pauv ntawm kev ua haujlwm yuav tsum tau siv rau kev sim, thiab cov qeb yuav tsum tau txiav txim siab raws li hom degradation thiab siv lub voj voog.
Saib cov yas biodegradable; compostable plastics; thermo-degradable plastics; lub teeb-degradable plastics.
12. Biodegradable yas (biodegradable yas)
Nyob rau hauv tej yam kev mob xws li av thiab/los yog xuab zeb av, thiab/los yog tej yam kev mob xws li composting tej yam kev mob los yog anaerobic digestion tej yam kev mob los yog nyob rau hauv aqueous kab lis kev cai kua, degradation yog tshwm sim los ntawm kev ua ntawm microorganisms nyob rau hauv cov xwm, thiab thaum kawg degraded tag nrho rau hauv carbon dioxide ( CO2) lossis / thiab methane (CH4), dej (H2O) thiab mineralized inorganic ntsev ntawm cov khoom muaj nyob rau hauv, nrog rau cov yas tshiab biomass.
Saib: Cov Plastics Degradable.
13.Heat- thiab/los yog oxide- degradable yas (heat- thiab/los yog oxide- degradable yas)
Cov yas uas degrade vim cua sov thiab/los yog oxidation.
Saib: Cov Plastics Degradable.
14. Diam duab-degradable yas ntawv (yees duab-degradable yas ntawv)
Cov yas uas degraded los ntawm kev ua ntawm ntuj tshav ntuj.
Saib: Cov Plastics Degradable.
15.compostable yas
Cov yas uas tuaj yeem degraded thiab disintegrated nyob rau hauv composting tej yam kev mob vim cov tshuaj lom neeg cov txheej txheem, thiab thaum kawg decomposed tag nrho rau hauv carbon dioxide (CO2), dej (H2O) thiab mineralized inorganic ntsev ntawm lub ntsiab muaj nyob rau hauv, nrog rau tshiab Biomass, thiab cov ntsiab lus ntawm cov hlau hnyav, kev kuaj tshuaj toxicity, cov khib nyiab seem, thiab lwm yam ntawm cov compost zaum kawg yuav tsum ua raws li cov qauv tsim nyog.
