Cov khoom tseem ceeb ntawm cov ntawv khob yog ntawv, thaum cov khoom qub ntawm cov ntawv yog ntoo thiab xyoob.Ntau tus neeg tuaj yeem pab tsis tau tab sis sib cav tias yog tias qhov kev loj hlob loj ntawm kev tsim cov ntawv khob yuav ua rau muaj kev siv ntoo ntau, thiab yuav ua rau muaj kev cuam tshuam ntawm cov khoom siv pov tseg, nws tseem yuav rhuav tshem cov ecological ib puag ncig mus rau qhov zoo. .Cov kev xav no yog nkag siab, tej zaum yuav tawm ntawm qhov kev xav ntawm qee qhov xwm txheej xav tau kev puas tsuaj ntawm hav zoov, ua rau muaj kev xav phem heev, txawm li cas los xij, niaj hnub no kev rhuav tshem hav zoov tau raug tswj tau zoo raws li txoj cai nruj thiab kev tswj hwm ntawm lub xeev.Tam sim no, tag nrho cov ntoo raw cov ntaub ntawv uas peb siv yog tsim nyog npaj regenerated forests uas yuav tsum tau felled, cov nqi hluav taws xob qauv yog ib tug economic hav zoov ntoo uas yuav tsum tau siv.Yog li ntawd, daim ntawv khob tsim kev lag luam tsuas yog tsav txoj kev loj hlob ntawm cov lag luam uas muaj feem xyuam, tsuav yog kev tswj kom tsim nyog, yuav tsis muaj qhov tshwm sim ntawm kev puas tsuaj ntawm ecological ib puag ncig uas tib neeg txhawj xeeb txog.Paper Cups coj thawj kev txhim kho kev lag luam yog kev lag luam ntawv, vim tias cov khoom tseem ceeb ntawm cov khob ntawv yog ntawv.Txawm hais tias tam sim no siv cov ntoo hauv cov phiaj xwm theem, tab sis txhawm rau txhim kho kev siv cov ntoo siab hauv papermaking thiab nrhiav lwm txoj hauv kev rau daim ntawv kuj yog qhov kev tshawb fawb txuas ntxiv.Tib neeg txoj kev mloog rau lub ecological ib puag ncig, tab sis kuj txhawb tib neeg cov ntaub ntawv rooj tog rov ua dua kev tshawb fawb.
Lwm cov khoom siv raw ntawm lub khob ntawv yog cov ntawv coated hauv tsev, cov ntawv PLA coated tuaj txawv teb chaws, PE coated ntawv.PE txheej yog txheej txheej tshuab (laminating tshuab) rau ntawm daim ntawv nrog ib txheej ntawm PE (polyethylene) zaj duab xis Polylactic acid fiber yog ib tug kiag li biodegradable hluavtaws fiber uas yuav tau los ntawm cov nplej.Cov khoom pov tseg tuaj yeem decomposed rau hauv carbon dioxide thiab dej los ntawm cov kab mob hauv av lossis dej hiav txwv.Thaum nws kub hnyiab, nws yuav tsis muab cov pa lom thiab ua rau lwm yam pa phem.Muaj ib pawg hydroxyl thiab ib pawg carboxyl nyob rau hauv ib qho lactic acid molecule, ntau lactic acid molecules ua ke, -OH nrog lwm cov molecules-COOH lub cev qhuav dej condensation,-COOH nrog rau lwm cov molecules-OH lub cev qhuav dej condensation, cov polymer lawv tsim yog hu ua polylactic acid.Polylactic acid tseem hu ua polylactide belongs rau tsev neeg polyester.Polylactic acid (PLA) yog ib yam khoom siv polymer uas tuaj yeem tau txais los ntawm polymerization ntawm lactic acid.Raws li qhov tshwj xeeb uas yuav tsum tau muaj kev tiv thaiv ib puag ncig siab thiab kev nyiam huv ntawm daim ntawv khob, nws yuav tsum tau txuas ntxiv txhawb txoj kev loj hlob ntawm PLA thiab PE thev naus laus zis mus rau kev coj ua siab dua.Qhov zoo ntawm cov zaub mov nws tus kheej xav tau kev saib xyuas, tab sis qhov zoo ntawm cov tais diav siv rau zaub mov thiab dej haus.
