A yas raug txiav txim siab biodegradable yog tias nws tuaj yeem degrade rau hauv dej, carbon dioxide, thiab biomass nyob rau hauv ib lub sijhawm teem (nyob ntawm cov qauv sib txawv). Yog li, cov ntsiab lus tsis yog synonymous. Tsis yog txhua yam bioplastics yog biodegradable . Ib qho piv txwv ntawm a uas tsis yog biodegradable bioplastic yog bio-based PET.

Dhau li ntawd, puas yog yas biodegradable lossis nonbiodegradable?

Tsis- biodegradable fossil-based polymers Lub sij hawm uas tsis yog biodegradable piav qhia txog cov polymers uas tsis tawg mus rau ib puag ncig ntuj, kev nyab xeeb ib puag ncig lub sijhawm los ntawm cov txheej txheem lom neeg. Feem ntau yas yog uas tsis yog biodegradable feem ntau vim yas yog dav siv vim nws cov nqi qis, versatility thiab durability.

Ib sab saum toj no, qhov txawv ntawm biodegradable thiab nonbiodegradable pov tseg yog dab tsi? Qhov yooj yim Qhov sib txawv ntawm biodegradable thiab tsis biodegradable yog li biodegradable cov khoom decompose los yog tawg lawm. Tsis yog biodegradable cov khoom tsis muaj. Loj ntim ntawm uas tsis yog biodegradable pov tseg noj ntau dhau pov tseg thiab muaj feem cuam tshuam rau ib puag ncig.

Tom qab ntawd, puas muaj cov yas uas biodegradable?

Biodegradable plastics yog tsim los ntawm tag nrho cov-natural cog cov ntaub ntawv. Cov no muaj xws li pob kws roj, txiv kab ntxwv peels, starch, thiab nroj tsuag. Ib txwm yas yog ua los ntawm cov tshuaj chemical fillers uas tuaj yeem tsim kev puas tsuaj rau ib puag ncig thaum tso tawm thaum lub yas yog melted.

Cov piv txwv ntawm biodegradable pov tseg yog dab tsi?

Piv txwv ntawm Biodegradable cov ntaub ntawv, feem ntau hu ua "bio-kua pov tseg", muaj xws li hauv qab no:

  • Tib neeg thiab tsiaj pov tseg.
  • Cov khoom cog, ntoo, ntawv, zaub mov pov tseg, nplooj, nyom clippings, tej yam ntuj tso khoom.
  • Tseem nyob ntawm kev tuag ntawm cov tsiaj muaj sia.
