Kev lag luam ncig ua si lub luag haujlwm tseem ceeb, hloov pauv hauv kev siv cov khoom siv rov ua dua tshiab, tig ib txoj kab "coj- ua- pov tseg" qauv raucov khoom siv ntawvrau hauv qhov kaw - lub voj voog uas txo cov peev txheej, pov tseg, thiab kev puas tsuaj ib puag ncig. Hauv qab no yog cov ncauj lus kom ntxaws txog nws cov haujlwm tseem ceeb thiab qhov cuam tshuam, nrog rau kev tsom mus rau cov ntawv thov xws li cov ntawv cement sacks, ntim khoom noj, thiab ntawv thermal:
Kaw cov khoom siv: Los ntawm khib nyiab mus rau raw khoom
Lub hauv paus ntsiab lus tseem ceeb ntawm kev lag luam ncig yog khaws cov nqi ntawm cov ntaub ntawv kom ntev li ntev tau. Cov ntaub ntawv rov ua dua tshiab ua rau qhov no los ntawm kev hloov cov ntawv pov tseg (xws li, siv cov ntaub ntawv kraft cement sacks, pov tseg ntim, lossis xa ntawv -cov khoom siv ntawv) los ntawm cov chaw pov tseg thiab cov chaw tsim hluav taws xob, thiab hloov nws rov qab rau hauv cov khoom siv raw rau cov ntawv tshiab.
- Rau kev lag luam xws li ntim cov cement: Siv cov hnab ntawv kraft (tom qab ntxuav kom tshem tawm cov cement seem) yog pulped thiab rov siv dua rau hauv cov hnab tshiab lossis qis dua - cov khoom ntawv qib. Qhov no tshem tawm qhov yuav tsum tau rho tawm nkauj xwb ntoo pulp rau txhua lub voj voog ntau lawm, txo qis deforestation siab.
- Tsis zoo li cov qauv linear- qhov twg cov khoom siv ntawv pov tseg tom qab siv ib zaug- kev lag luam ncig ua kom ntseeg tau tias cov fiber ntau hauv cov khoom siv rov ua dua tshiab khaws nws cov txiaj ntsig, tsim kom muaj lub voj voog txuas ntxiv ntawm kev tsim khoom, noj, rov ua dua, thiab rov ua dua - ntau lawm.
01
Txo kev siv cov peev txheej thiab cov pa roj carbon hneev taw
Cov khoom siv rov ua dua tshiab yog qhov muaj peev txheej tsawg dua - siv ntau dua li kev tsim cov paj ntoo, thiab kev lag luam ncig ua kom zoo dua qhov kev ua tau zoo los ntawm kev saib xyuas cov khoom siv rov ua dua tshiab dua cov ntaub ntawv nkauj xwb:
- Kev txuag hluav taws xob: Kev tsim cov khoom siv rov ua dua tshiab siv 60-70% lub zog tsawg dua li cov paj ntoo kraft (uas xav tau lub zog- cov txheej txheem hnyav xws li ntoo chipping, tshuaj pulping, thiab tshuaj dawb). Qhov no txiav cov pa roj tsev cog khoom (GHG) emissions loj, raws li cov pob zeb nkauj xwb feem ntau cia siab rau cov fossil fuels los yog tsis muaj txiaj ntsig biomass.
- Kev txuag dej: Kev ua cov khoom siv rov ua dua tshiab yuav tsum muaj txog li 90% dej tsawg dua li cov khoom siv nkauj xwb, txo cov dej khib nyiab thiab txo kev ntxhov siab ntawm cov dej tshiab.
- Kev txuag cov ntaub ntawv raw: Los ntawm kev hloov cov khoom siv rov ua dua tshiab rau cov ntaub ntoo nkauj xwb, kev lag luam ncig khaws cia cov peev txheej hav zoov, tiv thaiv biodiversity thiab carbon sequestration peev ntawm hav zoov.
02
Tsav Systemic Innovation thiab kev lag luam kev sib koom tes
Kev lag luam ncig tsis nres ntawm kev rov ua dua tshiab - nws thawb rau kev hloov pauv thoob plaws tag nrho cov khoom siv los txhim kho kev siv cov khoom siv rov ua dua tshiab:
- Tsim kom muaj kev rov ua dua tshiab: Cov neeg tsim khoom muaj kev txhawb siab los tsim cov khoom lag luam (xws li cov hnab cement, ntim khoom noj) nrog cov khoom siv rov ua dua tshiab hauv siab. Qhov no txhais tau tias txo qis cov txheej txheem uas tsis yog- rov ua dua tshiab, siv cov ntaub ntawv tsim nyog, thiab tsis txhob muaj kev sib kis (xws li, txo cov cement seem ntawm cov hnab los ntawm kev txhim kho lub hnab).
- Extended Producer Responsibility (EPR): Cov cai hauv paus hauv kev lag luam ncig (xws li, EPR schemes) xav kom cov tuam txhab cement thiab ntawv ua lub luag haujlwm rau lawv cov khoom kawg - ntawm - kev tswj hwm lub neej. Qhov no suav nrog kev sau nyiaj txiag thiab kev rov ua dua tshiab rau cov hnab ntim khoom siv, ua kom muaj kev ruaj khov ntawm cov khoom siv rov ua dua tshiab.
- Hla - kev koom tes hauv kev lag luam: Piv txwv li, cov neeg tsim khoom cement tuaj yeem koom tes nrog cov ntawv zeb thiab cov tuam txhab tswj xyuas khib nyiab los tsim cov kaw- lub voj voog - sau cov hnab ntim khoom siv ncaj qha los ntawm cov chaw tsim kho, ntxuav lawv, thiab rub lawv rau kev tsim cov hnab tshiab.
03
Txo cov khib nyiab thiab cov pa phem
Kev lag luam ncig hais txog ob qho kev pov tseg tseem ceeb- cuam tshuam txog cov teeb meem cuam tshuam nrog cov khoom lag luam:
- Kev faib cov khib nyiab pov tseg: Cov ntawv pov tseg (tshwj xeeb yog cov khoom siv coated xws li PE- cov hnab yas laminated) tuaj yeem siv sij hawm ntau xyoo los decompose nyob rau hauv qhov chaw pov tseg thiab tej zaum yuav tso tawm methane (ib lub zog GHG) yog anaerobically decomposed. Lub voj voog kev lag luam tso cov pov tseg no mus rau hauv cov kwj deg rov ua dua tshiab rau cov khoom siv pulp, tshem tawm cov emissions thiab txo cov khoom pov tseg.
- Txo cov pa phem: Kev tsim cov paj ntoo nkauj xwb tsim cov khoom muaj kuab lom (xws li lignin, cawv dub, thiab tshuaj dawb xws li tshuaj chlorine). Recycled pulp processing hla ntau ntawm cov kauj ruam no, txo qhov kev pheej hmoo ntawm dej thiab huab cua paug los ntawm cov ntawv zeb. Rau cov khoom siv coated ntawv, kev lag luam ncig kuj tseem ua rau muaj kev hloov pauv tshiab hauv cov txheej txheem sib cais yooj yim (xws li, cov hmoov txhuv nplej siab uas tsis yog PE) los txhim kho cov dej khib nyiab rov qab.
04
Txhim kho Economic Resilience
Kev lag luam ncig hloov pauv cov khoom siv rov ua dua tshiab rau hauv kev lag luam, tsis yog kev lav phib xaub:
- Kev txuag nqi: Rau cov ntawv thiab cov chaw tsim khoom cement, cov khoom siv rov ua dua tshiab feem ntau pheej yig dua cov ntaub ntawv nkauj xwb, txo cov nqi raw khoom.
- Cov nyiaj tau los tshiab: Cov tuam txhab tswj cov khib nyiab thiab cov chaw rov ua dua tshiab tuaj yeem tsim cov nyiaj tau los ntawm kev ua cov ntaub ntawv pov tseg rau hauv siab -cov khoom siv rov ua dua tshiab rau cov neeg yuav khoom lag luam.
- Kev ua raws cai: Raws li tsoomfwv nruj nruj rau ib puag ncig cov cai (piv txwv li, cov se carbon, kev txwv tsis pub pov tseg), cov tuam txhab siv cov khoom siv rov ua dua tshiab raws li kev lag luam thoob ntiaj teb zam kev nplua thiab tau txais kev sib tw hauv kev lag luam ruaj khov.
