Biodegradable thiab compstable

Cov lus txhais thiab tsis siv

Biodegradable thiab compstable yog feem ntau siv sib txuas lus los piav qhov kev sib tawg ntawm cov organic cov ntaub ntawv hauv cov ncauj lus tshwj xeeb. Txawm li cas los xij, kev siv ntawm "biodegradable" hauv kev ua lag luam tau coj mus tsis meej pem cov neeg siv khoom. Txhawm rau hais txog qhov no, biobag presominantly lub sij hawm "compotable" rau peb cov khoom muaj pov thawj.

Biodegradity

Biodegradity yog hais txog cov khoom siv muaj peev xwm los yauv ua kom tsawg tsawg, tsim co₂, H₂O, methane, thiab cov ntsev ntxhia. Cov kab mob me, feem ntau pub los ntawm cov organic pov tseg, tsav tus txheej txheem no. Txawm li cas los xij, lub sijhawm tsis muaj feem ntau, raws li txhua cov ntaub ntawv nws kawg, hais txog qhov xav tau los qhia kom meej ib puag ncig rau bookegradation.

Qhov teb

Composting koom nrog microbial kev zom kom tawg cov organic pov tseg rau cov organic pov tseg rau hauv nplooj lwg, muaj txiaj ntsig rau av txhim kho thiab kev ua qoob loo. Kev kub tshaj plaws, dej, thiab qib oxygen yog qhov tsim nyog rau cov txheej txheem no. Hauv cov phaes ntawm cov organic pov tseg, myriad microbes noj cov ntaub ntawv, hloov lawv mus rau hauv nplooj lwg. Tag nrho cov compostility yuav tsum muaj kev ua raws li cov qauv nruj xws li European or

Cov Qauv Thoob Ntiaj Teb

Sib nrug los ntawm European Cov Qauv Kawm Endance en 13432, ntau lub tebchaws muaj lawv cov qauv, suav nrog peb tus qauv ATM D6400 thiab Australian Acch As4736. Cov qauv no ua haujlwm raws li cov qauv tsim khoom, lub cev muaj cai, cov chaw ua haujlwm suav nrog, thiab cov neeg siv khoom.

Cov Qauv Rau Cov Ntaub Ntawv Compostable

Raws li European cov qauv en 13432, cov ntaub ntawv txuas ntxiv yuav tsum muaj ntawv pov thawj:

• Biodegradity ntawm tsawg kawg 90%, hloov mus rau hauv co₂nyob rau hauv rau lub hlis.
• Ua kom tsis sib xws, ua rau muaj tsawg dua 10% cov seem.
• Sib xyaw nrog cov txheej txheem composting.
• Cov qib hnyav ntawm cov hlau hnyav, tsis muaj kev sib cuam tshuam zoo.

Biodegradability tsis tau lees tias compostability; Cov ntaub ntawv yuav tsum tau tawg ua ntu zus ib zaug. Conversely, cov ntaub ntawv uas tawg rau hauv cov me-biodegradable micro-daim rau ib lub voj voog tsis tau xav txog compostable. Rau 13432 sawv cev rau kev sib haum xeeb cov qauv kev ua haujlwm, ua raws li European Cov Ntawv Qhia 94/62 / EC ntawm Ntim pov tseg.
