Kev loj hlob thiab cov ntawv thov ntawm biodegradable plastics

Lub ntsiab txhais ntawm biodegradable plastics, nws yog los taw rau xwm, ib puag ncig dej, ib puag ncig dej, kev ua txhaum los ntawm kev ua kom microbial ntawm xwm txheej, thiab thaum kawg Decomposed rau hauv cov pa roj carbon dioxide (CO2) thiab / lossis methane (ch4), dej (xws li cov roj ntsha tshiab (xws li cov microorganisms, thiab lwm yam) ntawm cov yas.

Kev tsim khoom thiab faib ntawm biodegradable plastics

Raws li cov ntaub ntawv kawg tso tawm los ntawm European Bioplastics Association Nyob rau lub Cuaj Hli 2019, txij li lub Cuaj Hli 2019, lub ntiaj teb ntau lawm muaj peev xwm ntau lawm ntawm biodegradable plastics yog2144,000 tons;

Pla (polylactic acid) yog628,000 Tons, Accounting rau29.3%;

PBAT (Polyadipic Acid / Butylene Terephthalate) yog606,800 tons, Accounting rau28.3%;

Cov hmoov txhuv nplej siab raws li cov khoom siv hluav taws xob96.27 Tons, Accounting rau44.9%ntawm lub ntiaj teb biodegradable muaj peev xwm.

Cov av tsis txaus ntseeg

PBAT, PHA, PCCL thiab PBS yuav ua kom tiav tsis taus tom qab 5 lub hlis.

Qhov nqi ntawm cov ntaub ntawv Pla yog qhov qeeb, tsuas yog 0.23% ib xyoos.

PLA thiab PKAT tuaj yeem ua kom tiav raws li ib nrab ib xyoos tom qab kev sib xyaw.

Cov dej ua raws

Pha thiab PKAT tuaj yeem ua kom tiav hauv kev ua tiav hauv 30 ~ 60 hnub nyob rau hauv cov dej hiav txwv simulated ntawm 25 ± 3 ℃.
