Cov ntaub ntawv ntawm tu cov ntsiav tshuaj tsuas yog suav nrog cov enzymes biodegradable, surfactants thiab tshuaj tua kab mob tua kab mob.
Biodegradable enzymes yog ib puag ncig kev phooj ywg tu tej yam uas tuaj yeem zoo huv thiab tiv thaiv pem teb. Surfactants muaj kev cuam tshuam lub cev xws li ntub dej, tiv thaiv, ntxuav, thiab kev tawm tsam zoo li qub, uas txhim kho cov nyhuv tu. Cov neeg sawv cev tua kabmob tau siv rau kev tshem tawm thiab kom tsis muaj menyuam kom paub meej tias hauv pem teb muaj kev nyab xeeb dua thiab ntau dua kev huv si tom qab tu.
Tsis tas li ntawd, qee cov ntsiav tshuaj tu, xws li cov khawv koob nqus tu cov ntsiav tshuaj, yog ua los ntawm cov ntoo pulp paj rwb, uas muaj cov adsorption thiab ruaj khov. Ntoo pulp pulp paj rwb yog ua los ntawm cov ntoo nkauj xwb ntoo thiab compressed los ntawm cov txheej txheem tshwj xeeb. Nws muaj cov adsorption zoo thiab ntxuav lub zog, thiab yog ib puag ncig zoo thiab yooj yim rau degrade.
