Dab tsicompostable ntawv khobtsis yog lub khob ntawv yas?Qhov txawv ntawm nws thiab atus kheej daim ntawv khob?
Ntau tus neeg siv khoom yuav tsis paub tias lawv cov khob ntawv pov tseg ib txwm zoo li ib puag ncig tus phooj ywg, tab sis lawv nyob rau hauv cov khoom siv tsis siv neeg hauv kev faib cov khib nyiab.
"Cov khob ntawv yog txwv los ntawm cov khoom siv ntawv tsis yog cov yam ntxwv dej tsis zoo, txhawm rau tiv thaiv cov dej tsis zoo, cov yas polyethylene (PE) coated zaj duab xis yuav muab ntxiv rau cov khob ntawv." Raws li lub tuam txhab ntim yas hauv Haikou, Hainan, qhov kub. lub khob haus yuav coated nyob rau hauv lub khob, thiab cov dej txias yuav coated nyob rau hauv thiab sab nraum lub khob.Nws tsis yooj yim rau kev cais tawm ntawm daim ntawv hauv cov txheej txheem rov ua dua tshiab, yog li nws tau muab faib ua cov khib nyiab uas tsis yog rov ua dua tshiab.
Nws tau nkag siab tias txij li lub Kaum Ob Hlis 1, Hainan kev "txiav yas yas", tau suav nrog hauv Hainan xeev txwv kev tsim khoom thiab muag khoom siv cov khoom siv yas pov tseg uas tsis yog biodegradable (thawj batch) ntawm cov khoom yas yuav txwv tsis pub ntau lawm thiab muag, lub tuam txhab kev tshawb fawb thiab kev tsim kho uas tsim los ntawm cov txheej txheem dej es tsis txhob siv cov ntawv khob tshuaj polyethylene txheej tsis muaj lub khob yas, paub txog tag nrho biodegradation.
Seb lub khob ntawv yas ua los ntawm lub tuam txhab tsim nyog yog tus qauv.Cov qauv ntawm tsis muaj lub khob ntawv yas (xws li tsis muaj cov ntawv khob yas) hais tias ”cov ntawv khob hauv paus yuav tsum ua tau raws li QB / T 4032.
