Nyob rau hauv xyoo tas los no, nrog rau kev siv dav ntawm bio-raws li tawv, tau muaj kev txuas ntxiv txuas ntxiv ntawm cactus tawv cov khoom, cov khoom siv tawv tawv, cov khoom siv tawv nqaij, cov khoom siv pob kws tawv thiab lwm yam. Peb kuj tau ntsib nrog cov teeb meem rov ua dua ntawm bio-raws li tawv, thiab cov cuab yeej siv thev naus laus zis ntawm bio-raws li tawv tau nyiam ntau yam hauv kev txhim kho kom ruaj khov. Recycling thev naus laus zis feem ntau yog mob siab rau txo cov peev txheej pov tseg, txo cov pa phem ib puag ncig thiab txhim kho cov khoom siv rov qab siv dua. Cov hauv qab no yog qee yam kev cog ntoo tawv rov ua dua tshiab:
1.Cog raws li vegan tawv - mechanical recycling method
Kev siv tshuab ua dua tshiab yog txoj hauv kev zoo tshaj plaws kom rov qab tau cov tawv nqaij bio-raws li, uas feem ntau cuam tshuam nrog lub cev crushing, txiav, thiab sib tsoo cov khib nyiab bio-raws li tawv los hloov nws mus rau hauv cov ntaub ntawv tshiab.
2. Bio-raws li tawv - chemical recycling method
Cov txheej txheem siv tshuaj lom neeg muaj xws li enzymatic hydrolysis, acid-base kev kho mob, thiab lwm yam. Los ntawm degrading cellulose, protein thiab lwm yam khoom hauv tawv, lawv tuaj yeem hloov mus rau hauv cov ntaub ntawv rov siv tau lossis tshuaj. Qhov zoo ntawm txoj kev no yog tias nws tuaj yeem ua tiav cov khoom siv rov ua dua tshiab, tab sis nws yuav ntsib tus nqi siab thiab muaj peev xwm cuam tshuam rau ib puag ncig.
3. Zaub tawv - pyrolysis rov qab txoj kev
Pyrolysis rov qab thev naus laus zis siv qhov kub thiab txias tsis muaj oxygen los ua cov tshuaj tiv thaiv pyrolysis, hloov cov khib nyiab bio-raws li tawv rau hauv cov khoom siv roj, kua lossis khoom. Cov seem tom qab pyrolysis tuaj yeem siv los ua roj lossis lwm yam khoom siv raw.
4. Tawv vegan- Biodegradable txoj kev
Qee cov tawv nqaij bio-based muaj cov khoom ntuj biodegradable thiab tuaj yeem decomposed los ntawm cov kab mob nyob rau hauv cov xwm txheej tsim nyog. Los ntawm kev ua kom zoo dua ntawm cov yam ntxwv no, cov tawv nqaij pov tseg tuaj yeem kho los ntawm kev degradation, hloov mus rau hauv cov khoom tsis zoo.
Yog xav paub ntxiv, nyem rau ntawm qhov txuas thiab tuaj xyuaspeb lub khw!
