Raws li lub ntsiab lus ntawm cov khoom ntim ntawm cov quav, lawv tuaj yeem faib ua peb yam nram qab no:
(1) PLA, PHA biodegradable plastics los ntawm kev siv bio-fermentation siv cov hmoov txhuv nplej siab raws li cov ntaub ntawv raw haus ntau ntau cov khoom noj, yog li qhov chaw loj hlob tsis muaj.
(2) Aliphatic polycarbonate (APC) -ntshav ntim cov plastics uas ua los ntawm carbon dioxide, uas yog siv carbon dioxide, ib qho khoom siv uas yog tam sim no raug screamed los ntawm txhua tus neeg, tsis noj haus thiab txo cov pa roj carbon emissions.
