Raws li ob lub siab ntawm lub ntiaj teb cov yas txo qis thiab carbon nruab nrab, Tuam Tshoj txoj kev lag luam ntawv sawv ntawm qhov pib ntawm lub voj voog tshiab. "Daim ntawv hloov cov yas" tsis yog tsuas yog hloov cov khob yas, ntim khoom, thiab ntim khoom noj nrog ntawv. Hloov chaw, nws suav nrog kev tsim kho cov thev naus laus zis thiab kev lag luam ntawm daim ntawv- raws li ntim raws li cov kev txwv nruj ntawm "kev yooj yim ntawm kev rov ua dua tshiab, tus nqi rov qab siab dua, thiab kev txo cov pa roj carbon monoxide."
Nyob rau hauv lub teb chaws, lub "Kev xav ntawm ntxiv dag zog rau kev tswj ntawm cov pa phem" tau qhia meej meej qhov tseem ceeb "recyclable, yooj yim recyclable, thiab biodegradable" raws li ib theem zuj zus rau lwm txoj kev. Thawj-tier nroog tau txhais cov lus qhia no rau hauv kev nqis tes ua los ntawm "kev txwv yas + txhim kho kev txheeb xyuas + xoom- lub nroog khib nyiab" pib. Beijing, Shanghai, Hong Kong, thiab Hainan tau ua tiav cov kev txwv nruj rau ib leeg - siv cov khoom siv yas thiab ntawv- cov qauv yas sib xyaw, thaum tib lub sijhawm hais txog qhov xav tau los txhawb kev rov ua dua tshiab thiab siv cov khoom siv txuas ntxiv dua tshiab. EU's Packaging and Packing Waste Regulation (PPWR) tau teeb tsa lub hom phiaj ntawm "tag nrho cov ntim tau rov qab los ntawm kev lag luam los ntawm 2030," thaum EU Bioeconomy Strategy muab kev txhawb nqa dav dav rau kev hloov pauv no. Hauv Teb Chaws Asmeskas, cov lus qhia ntsuab thiab lub xeev txoj cai lij choj tau txhawb nqa ib puag ncig kev thov xws li 'compostable' thiab "recyclable" rau qhov tseeb ntawm qhov chaw muaj thiab cov ntaub ntawv pov thawj. High-cov nroog loj nyob hauv nroog ntsib ntau yam kev txwv- av tsis txaus, nqi, thiab NIMBY cuam tshuam{14}} ua kom loj - nplai composting infrastructure nyuaj rau xa mus. "Prioritizing uas twb muaj lawm recycling thiab rov qab systems" yog tshwm sim raws li kev pom zoo.
Tawm tsam qhov keeb kwm yav dhau no, cov kev txwv ntawm "Paper-rau-Plastic 1.0" yog qhov pom tseeb ntxiv: cov qauv "paper + PE txheej" tus qauv coj zoo li ntawv thaum siv tab sis zoo li cov yas hauv cov khib nyiab. Cov txheej thiab fibers tau kaw ua ke heev, ua rau pulping nyuaj thiab kim. Cov tuam txhab lag luam rov ua dua tshiab tsis kam lees txais nws, thiab cov ntawv zeb tsis kam siv nws. Yog li -hu ua "compostable plastic cups" thiab "bioplastic food containers" tsis tshua nkag mus rau hauv cov txheej txheem composting tiag tiag yam tsis muaj kev sib xyaw ua ke thoob plaws thiab cov txheej txheem sorting, feem ntau tsuas yog "conceptual composting." Thaum kawg, cov kev txwv tseem ceeb ntawm "Paper-rau-Plastic 1.0" npau taws rau qhov no: Daim ntawv zoo li ntawv, tab sis nws txoj hmoo tsom iav yas- siab- cov ntawv fibers zoo tau raug tshem tawm los ntawm lub voj voog ntawm daim ntawv los ntawm PE yas zaj duab xis qauv tsim.
Cov ntsiab lus tseem ceeb ntawm "Paper-rau-Plastic 2.0" ua kom pom tseeb nyob rau hauv "khoom me me, kev cuam tshuam loj rau ib puag ncig" logic: Puas yog cov qauv tsim thiab txheej txheem tsim ua kom daim ntawv -raws li ntim khoom noj kom tau raws li dej tsis kam, roj tsis kam, kub sealing, thiab kev tiv thaiv kev tiv thaiv thaum ua tau raws li cov ntaub ntawv siab thiab cov ntaub ntawv pov thawj? Qhov no yuav tso cai rau nws rov qab mus rau cov ntawv zeb tiag tiag thiab xa cov txiaj ntsig zoo ntawm cov yas thiab cov pa roj carbon ntau.
Bio-raws li cov txheej txheem dej hauv dej, ua piv txwv los ntawm BASF thiab DuPont's Bioten™ Plus sib npaug thoob ntiaj teb thiab Bioten™ Pro ultra- cov kab ke ua haujlwm tau zoo, sawv cev rau txoj hauv kev thev naus laus zis tsim los daws qhov kev sib tw no. Raws li txoj cai ntawm kev txo cov yas thiab cov pa roj carbon emissions ntawm qhov chaw, cov tshuab no ua ke nrog dej-raws li dispersion technology nrog interfacial engineering tsim. Lawv xa cov dej tsis kam, roj tsis kam, thiab kub sealability xav tau rau cov ntawv khob thiab tais txawm tias qhov hnyav hnyav. Kev koom ua ke ntawm bio-raws li polymers xws li BASF's biomass acrylic thiab Microstructure Factory's PHA txo qhov kev cia siab ntawm cov pob txha-raws li resins thaum pab txhawb rau cov pa roj carbon ntau dua hauv kev ntsuas lub neej. Raws li cov qauv ntawv zeb pulping tej yam kev mob, txheej txheej sai sai cais tawm ntawm fibers, cia fibers nkag mus rau hauv cov txheej txheem repulping thaum txheej txheej khib nyiab yog centrally pov tseg ntawm txoj kev tsim. Piv nrog rau cov ntawv laminated pa, cov qauv no qhia tau hais tias muaj kev ua tau zoo tshaj plaws hauv cov nqi rov qab, cov ntawv tshuab hloov tau, thiab lub peev xwm thauj khoom. Qhov no ua rau nws tau txais kev lees paub ntau dua los ntawm cov chaw lag luam rov ua dua tshiab thiab cov ntawv zeb, thaum tseem muab txoj hauv kev paub tseeb rau cov ntawv ua lag luam xws li APP Sinar Mas Group-uas pheej tsav tsheb ntsuab papermaking innovation-txhim kho cov khoom xws li khob ntawv thiab zaub mov- qib cardboard.
Rau Tuam Tshoj txoj kev lag luam ntawv, qhov no sawv cev tsis yog cov khoom siv tshiab xwb tab sis kev hloov pauv tswv yim los ntawm "muag cov ntawv hauv paus rau kev muag cov kev daws teeb meem." Los ntawm kev tsom mus rau cov xwm txheej tshwj xeeb xws li khob haus dej kub, khob dej txias, cov thawv ntim khoom, thiab cov khoom ntim txias, kev lag luam tab tom tsim cov ntawv ua haujlwm nyob rau ntawm "cov ntawv qib + txheej txheej + txheej txheem qhov rais" nyob rau hauv "me me khob, loj ib puag ncig cuam tshuam" logic. Thaum muab qhov tseem ceeb "kev yooj yim ntawm kev rov ua dua tshiab thiab kev rov ua dua siab dua," Duobai City Bioten's bio-raws li dej- cov txheej txheem kuj tseem muaj cov kev xaiv compostable thiab biodegradable rau cov xwm txheej nrog cov chaw tsim nyog thiab sorting systems. Los ntawm cov kev ntsuas tseem ceeb xws li cov khoom siv raw kev tiv thaiv kev nyab xeeb, cov txheej txheej nyias nyias, txhim kho cov khoom thaiv, cov cua sov zoo dua - sealing thiab kev ua kom yoog raws, cov khoom siv rov ua dua tshiab, thiab cov khoom siv cov pa roj carbon hneev taw, nws txhawb kev sib koom ua lag luam rov ua dua tshiab, cov tuam txhab ua lag luam, thiab tsoomfwv hauv nroog hauv kev tsim cov ntawv hauv cheeb tsam -raws li ntim cov khoom siv rov ua dua tshiab. Txoj hauv kev no ntxiv dag zog rau kev ntseeg siab thiab kev sib txuas lus nrog cov tswv lag luam thiab cov koom haum tswj hwm.
Thaum cov tuam txhab ntawv hloov lawv lub siab los ntawm "peb ntau tons ntawm ntawv tuaj yeem peb muag" mus rau "peb tons ntawm ntawv tuaj yeem siv dua, pes tsawg tons ntawm fiber ntau peb tuaj yeem tsim dua tshiab, thiab pes tsawg tons ntawm cov pa roj carbon emissions peb tuaj yeem txo," "Paper Hloov Plastic 2.0" tsis tas yuav yog ib qho lus hais thiab dhau los ua lub zog txhawb kev loj hlob ntawm kev lag luam. Rov qab mus rau lub ntsiab lus ntawm kev lag luam ncig-ua kom cov ntawv xa rov qab mus rau cov ntawv zeb tiag tiag- sawv cev rau lub sijhawm zoo tshaj plaws rau Tuam Tshoj txoj kev lag luam ntawv hauv lub voj voog no.
