V. I-biodegradability egaywa kabusha yezinkomishi zephepha lika-ayisikhilimu
Iphepha le-wood pulp lingagaywa kabusha futhi linokonakala. Lokhu kuthuthukisa kakhulu ukugaywa kabusha kanye nokubola kwe-biodegradability yeizinkomishi zika-ayisikhilimu.
Ngemva kwesikhathi eside sokuthuthukiswa, indlela evamile yokubola izinkomishi zephepha le-ayisikhilimu kanje. Phakathi nezinyanga ezi-2, i-lignin, i-Hemicellulose ne-cellulose yaqala ukuwohloka futhi kancane kancane yaba mancane. Kusukela ezinsukwini ezingama-45 kuye kwezingama-90, inkomishi icishe ibole ibe yizinhlayiya ezincane. Ngemuva kwezinsuku ezingama-90, zonke izinto ziyafakwa nge-oxidized bese ziguqulwa zibe umhlabathi nezakhi zezitshalo.
Okokuqala,izinto eziyinhloko zezinkomishi zephepha lika-ayisikhilimu yi-pulp nefilimu ye-PE. Zombili izinto ezisetshenziswayo zingagaywa kabusha. I-Pulp ingaphinda isetshenziswe ephepheni. Ifilimu ye-PE ingacutshungulwa futhi yenziwe eminye imikhiqizo yepulasitiki. Ukugaywa kabusha nokusebenzisa kabusha lezi zinto kunganciphisa ukusetshenziswa kwensiza, ukusetshenziswa kwamandla, nokungcoliswa kwemvelo.
Okwesibili,izinkomishi zephepha lika-ayisikhilimu zine-biodegradability. I-Pulp ngokwayo iyinto ephilayo ebola kalula ngama-microorganisms. Futhi amafilimu e-PE awonakaliswa nawo angonakaliswa ama-microorganisms. Lokhu kusho ukuthi izinkomishi zika-ayisikhilimu ngokwemvelo zingakwazi ukuwohloka zibe amanzi, i-carbon dioxide, kanye ne-organic matter ngemva kwesikhathi esithile. Ngakho, empeleni akubangeli ukungcoliswa kwemvelo.
Ukucekeleka phansi kwezinto eziphilayo kusemqoka kakhulu ekuvikelweni kwemvelo. Ngokukhula kwezinkinga zemvelo ezikhulayo emhlabeni wonke, intuthuko esimeme isiphenduke isihloko esikhathazayo kuzo zonke izinhlaka zomphakathi.
Emkhakheni wokupakisha ukudla, izinto ezigaywa kabusha nezibolayo ziyindlela yentuthuko yesikhathi esizayo. Ngakho-ke, ukukhuthaza izinto zokupakisha ezigaywa kabusha nezibolayo zemvelo kubaluleke kakhulu ekuthuthukisweni kwemboni kanye nemboni yokuvikela imvelo.
