Vim tias muaj kev puas tsuaj ntuj tsim, cov cai hauv zos thiab lwm yam, cov khoom tsim tawm yuav tsum tsawg dua qhov muaj peev xwm ntau lawm. Vim tias cov nqi tsim khoom siab ntawm PVC hauv Tebchaws Europe thiab Nyij Pooj, lub ntiaj teb PVC ntau lawm muaj peev xwm yog nyob rau hauv Northeast Asia, uas Tuam Tshoj muaj txog ib nrab ntawm lub ntiaj teb no PVC ntau lawm muaj peev xwm.
Raws li cov ntaub ntawv cua, xyoo 2020, Tuam Tshoj, Tebchaws Asmeskas thiab Nyij Pooj yog cov chaw tsim khoom tseem ceeb PVC hauv ntiaj teb, nrog rau kev tsim khoom muaj peev xwm suav txog 42%, 12% thiab 4% feem.

Cov chaw cog qoob loo ntawm cov txheej txheem ethylene yog nyob rau hauv cov ntug hiav txwv dej vim tias cov khoom siv raw VCM los yog ethylene yuav tsum tau tuaj. Tuam Tshoj lub peev xwm ntau lawm suav nrog yuav luag ib nrab ntawm lub ntiaj teb, thiab nrog rau kev nthuav dav ntawm Tuam Tshoj txoj kev lag luam sab saud, PVC tsim muaj peev xwm ntawm ethylene txoj kev yuav nce ntxiv, thiab Tuam Tshoj yuav txuas ntxiv ua rau lub ntiaj teb PVC sib koom.
