Txo cov nqi bio-based resin yog qhov tseem ceeb rau kev lag luam
Ntsuab thiab cov pa roj carbon tsawg yog cov laj thawj tseem ceeb uas ua rau cov khoom siv sib xyaw ua los ntawm xyoob tau hloov cov hlau thiab cov cement los ntes kev lag luam kav dej. Xam tsuas yog raws li cov khoom tsim tawm txhua xyoo ntawm 10 lab tons ntawm cov kav dej siab sib xyaw ua los ntawm xyoob, piv nrog cov kav dej sib txuas, 19.6 lab tons ntawm cov thee txheem tau txuag thiab cov pa phem tau txo los ntawm 49 lab tons. tons, uas yog sib npaug rau kev tsim xya lub chaw ua haujlwm thee loj dua nrog cov khoom tsim tawm txhua xyoo ntawm 3 lab tons.
Kev siv tshuab ua los ntawm xyoob yog qhov tseem ceeb heev rau kev txhawb nqa "hloov yas nrog xyoob", tab sis cov thev naus laus zis no tseem nyob rau theem pib ntawm kev txhim kho. Tshwj xeeb, kev siv cov nplaum resin ib txwm yuav ua rau cov tshuaj lom neeg xws li formaldehyde yaj thaum lub sijhawm tsim khoom thiab siv, uas coj kev tsis yooj yim rau kev txhawb nqa thiab kev siv cov thev naus laus zis no. Cov teeb meem me me. Qee cov kws tshawb fawb tab tom tsim cov bio-based resins los hloov cov kua nplaum resin ib txwm muaj. Txawm li cas los xij, yuav ua li cas kom txo tus nqi ntawm cov bio-based resins thiab yuav ua li cas kom ua tiav kev lag luam tseem yog qhov kev sib tw loj heev uas xav tau kev siv zog los ntawm kev kawm thiab kev lag luam.
