1. Kev tshawb fawb tob ntxiv raws li kev siv sib txawv thiab ib puag ncig, thiab txhim kho cov qauv tsim los ntawm kev tshawb fawb molecular, tsim kom muaj sij hawm thiab tswj tau ib puag ncig ntawm cov yas degradable, tau dhau los ua cov ntsiab lus tseem ceeb hauv ntau lub teb chaws.
2. Ua haujlwm tshawb fawb thiab tsim kom muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo ntawm photosensitizers, oxidants, bio inducers, degradation promoters, stabilizers, thiab lwm yam., txhawm rau txhim kho kev tswj kom raws sijhawm, kev degradation sai tom qab siv, thiab ua tiav degradation.
3. Ceev nrooj ntawm biodegradable plastics los yog cov yas zoo tib yam sib xyaw nrog cov hmoov txhuv nplej siab, cellulose, los yog cov khoom siv inorganic rau filling, blending, los yog alloying thev naus laus zis, nrog rau tag nrho biodegradable plastics coated nrog cov ntaub ntawv ntuj, yog cov ntsiab lus kub hauv lub tshav pob.
4. Hydrolyzable plastics thiab edible plastics tau nyiam thoob ntiaj teb kev saib xyuas vim lawv cov haujlwm tshwj xeeb thiab kev siv, ua rau lawv yog lwm lub ntsiab lus kub rau cov ntaub ntawv ib puag ncig.
5. Txhawm rau txhawm rau txhim kho cov yas degradable, lub teb chaws tau cog lus kom nrawm rau kev tshawb fawb thiab tsim kom muaj kev sib koom ua ke, cov txheej txheem degradation, kev soj ntsuam, thiab cov qauv rau cov yas degradable.
6. Tshawb nrhiav thiab cog cov kab mob uas tuaj yeem degrade cov yas zoo tib yam, ua rau cov yas siv dav siv yooj yim kom degrade tom qab siv kom tau raws li ib puag ncig. Nyob rau tib lub sijhawm, qhov tseem ceeb yog txuas nrog rau kev cog qoob loo biodegradable nroj tsuag uas tuaj yeem tsim polyester, txhawm rau txo tus nqi ntawm biodegradable plastics thiab txhawb nqa lawv daim ntawv thov.
