Kev lag luam ncig tshem tawm cov kab "tsim- siv- pov tseg" qauv rauntawv cement hnabkev tsim khoom thiab tsim qhov kaw- lub voj kaw uas lub hom phiaj txo cov pov tseg ntawm txhua theem- los ntawm kev tsim cov khoom siv raw thiab kev tsim khoom mus rau kev siv cov khoom, kawg - ntawm - kev tswj lub neej, thiab cov khoom siv rov qab. Nws txoj kev koom tes yog kev sib koom ua ke, hais txog ob qho tib si ua ntej - siv cov khoom pov tseg thiab xa tawm - siv cov khib nyiab pov tseg (qhov dej khib nyiab loj tshaj plaws rau cov khoom no), nrog rau cov kev daws teeb meem tshwj xeeb rau cov pob zeb cement (xws li, cement contamination, PE lamination). Hauv qab no yog cov ncauj lus kom ntxaws txog yuav ua li cas nws txo qis pov tseg thoob plaws tag nrho lub neej:
Minimizes Virgin Raw Khoom khib nyiab los ntawm kev ua ntej siv dua tshiab
Lub hauv paus ntsiab lus ntawm kev lag luam hloov pauv kev tsim tawm kom deb ntawm kev cia siab ib leeg ntawm cov paj ntoo kraft (ib qho tseem ceeb ntawm cov ntaub ntawv pov tseg) rau cov ntaub ntawv siv los ua cov ntaub ntawv tseem ceeb rau cov ntawv cement sack ntau lawm, tsuas yog ib qho me me ntawm cov ntaub so ntswg los them rau cov fiber ntau degradation (paper fibers tuaj yeem rov ua dua 4-6 zaug).
- Cov khoom siv rov ua dua tshiab hla lub zog thiab cov peev txheej - cov kauj ruam tseem ceeb ntawm kev tsim cov paj ntoo (ntoo chipping, tshuaj pulping, bleaching) uas tsim cov txheej txheem pov tseg (xws li ntoo scraps, lignin byproducts, bleaching chemical sludge).
- Los ntawm kev hloov cov ntaub so ntswg rau nkauj xwb (feem ntau 30-70% rau cov cement sacks, nyob ntawm seb lub zog xav tau), cov tuam txhab txo cov khib nyiab los ntawm cov khoom siv raw thiab kev ua, thaum hloov cov ntawv pov tseg los ntawm qhov chaw pov tseg los ua khoom noj muaj txiaj ntsig.
- Rau cov neeg tsim cov hnab ntim cement, qhov no tseem txiav cov khoom pov tseg los ntawm ntau tshaj -cov ntaub ntawv nkauj xwb, raws li cov ntaub ntawv siv dua tshiab tsim kom muaj kev kwv yees, cov khoom siv raw hauv zos (vs. virgin pulp mov chains nrog ntau dua kev thauj mus los thiab cov khoom pov tseg).
01
Tsav tsim tsim kom rov ua dua tshiab kom tshem tawm cov khib nyiab uas tsis tsim nyog hauv hnab ntim khoom
Kev lag luam vaj tse incentivizes re-engineering daim ntawv cement sack tsim kom txo qis tsis yog- cov khoom siv rov ua dua tshiab thiab muaj kev pheej hmoo kis kab mob - ob qhov kev cuam tshuam loj tshaj plaws rau kev tshaj tawm - siv cov hnab ntim rov qab, uas txwv tsis pub ua rau 80% + ntawm cov cement sacks raug pov tseg.
- Txo / eco-coatings tus phooj ywg: Hloov cov tuab, tsis yog - cais PE laminations (ib txwm siv rau cov dej / dej tsis zoo), cov tuam txhab siv cov txheej txheem PE tsawg, cov lamination yooj yim sib cais, lossis cov khoom siv biocoatings (cov hmoov txhuv nplej siab, cov nroj tsuag -raws li waxes). Cov qauv tsim no tswj cov hnab ntim kev ua tau zoo tab sis tshem tawm cov pov tseg ntawm cov yas uas tsis tuaj yeem siv dua tshiab-paper composites, thiab ua kom pulping/recycling ua tau.
- Kev tsis sib haum xeeb-tsim qauv: Cov hnab ntim tau tsim kho nrog cov hlua khi los yog lub valve kaw uas txo cov cement hmoov leakage thaum lub sij hawm sau / tuav -qhov no txo qis ntawm kev tshaj tawm - siv cov cement paug (ib qho laj thawj tseem ceeb ntawm cov chaw rov ua dua tshiab tsis kam siv cov hnab ntim khoom), tig dab tsi ib zaug pov tseg rau hauv cov khoom siv pulp.
- Txoj cai-sizing: Lub voj voog tsim kuj ua kom zoo dua cov hnab ntim qhov ntev / qhov hnyav kom haum rau cov cement load, tshem tawm tshaj -kev tsim khoom (xws li, cov ntawv fiber ntau, txheej txheej tsis tsim nyog) uas tsim cov khoom pov tseg kom tsis txhob muaj.
02
Tshem tawm Post-Siv cov khib nyiab los ntawm kaw-Loop Collection thiab Recycling Systems
Qhov loj tshaj plaws pov tseg ntawm cov hnab ntawv cement yog tom qab- siv pov tseg (siv cov hnab ntim nrog cov cement feem ntau muab pov tseg raws li kev tsim kho / kev lag luam pov tseg). Txoj kev lag luam ncig daws qhov no los ntawm kev tsim kev lag luam- coj kaw- lub voj voog sau thiab ua cov tshuab uas tig cov hnab siv rov qab rau hauv cov ntaub so ntswg rau cov hnab cement tshiab- tshem tawm cov khib nyiab pov tseg thiab tsim cov khoom siv ncig.
- Tus tsim tawm- coj coj- cov kev pabcuam rov qab: Cov tuam txhab cement thiab cov hnab ntim khoom lag luam (raws li Extended Producer Responsibility/EPR cov cai, cov cuab yeej tseem ceeb hauv kev lag luam) pab nyiaj thiab ua haujlwm sau cov ntsiab lus ntawm cov chaw tsim kho, cov chaw tsim khoom cement, thiab cov chaw xa khoom siv rau cov ntawv cement sacks. Qhov no tshem tawm cov hnab ntim khoom pov tseg los ntawm kev tsim kho cov khib nyiab thiab xyuas kom lawv raug xa mus rau kev rov ua dua tshiab, tsis yog qhov chaw pov tseg.
- Kev tu tshwj xeeb: Lub voj voog kev lag luam tau nqis peev hauv qis- khib nyiab, dej- siv thev naus laus zis kom tshem tawm cov cement seem ntawm cov hnab ntim khoom siv (xws li, txhuam kom qhuav, qis- cov dej siab ntxuav nrog dej siv dua). Cov kauj ruam no hloov cov kab mob "khoom pov tseg" rau hauv cov khoom noj khoom haus huv huv - qhov txuas tseem ceeb uas kaw lub voj voog, vim cov ntaub ntawv huv huv tuaj yeem muab rov qab thiab siv los ua cov hnab ntawv cement tshiab.
- Kev siv Cascading: Rau cov hnab ntim khoom hnyav heev uas yuav tsum tau rov ua dua tshiab rau hauv cov hnab cement tshiab (feem pua me me), kev lag luam ncig tsis txhob muab pov tseg los ntawm kev siv cascading (downcycling) rau hauv qis dua - cov khoom siv qib ntawv (xws li, duab los qhia, ntim ntim, lub tsev rwb thaiv tsev). Qhov no ua kom tsis muaj khoom siv pov tseg, txawm tias nws tsis tuaj yeem ua haujlwm rau nws lub hom phiaj qub.

Txo kev tsim khoom thiab kev xa khoom pov tseg los ntawm kev ua haujlwm ua haujlwm
Dhau ntawm cov khoom siv, kev lag luam ncig ua kom zoo tshaj plaws hauv cov ntawv cement sack ntau lawm thiab kev faib tawm - tshem tawm cov khib nyiab los ntawm kev ua tsis tau zoo hauv kev tsim khoom, kev thauj mus los, thiab kev tswj cov khoom muag.
- Zero-kev tsim cov khib nyiab: Cov ntawv mills txais cov kev coj ua ncig (piv txwv li, ntawm-kev siv cov ntaub so ntswg, cov ntaub ntawv pov tseg los ntawm kev txiav / tsim cov hnab, txheej txheem dej rov ua dua tshiab) kom tshem tawm hauv - cov nroj tsuag pov tseg. Piv txwv li, daim ntawv trimmings los ntawm lub hnab txiav yog tam sim ntawd repulped thiab reintroduced rau hauv ntau lawm, es tsis txhob muab pov tseg raws li raug pov tseg.
- Localized supply chains: Circular economy prioritizes local recycled pulp production and sack manufacturing, txo kev thauj mus los rau raw cov ntaub ntawv (recycled pulp) thiab sacks tiav. Qhov no txo qis ntawm kev xa khoom pov tseg (xws li, cov hnab ntim khoom puas thaum lub sijhawm thauj mus los ntev-, ntim ntau dhau rau kev thauj khoom) thiab ua kom cov khoom pov tseg los ntawm kev thauj mus los tsawg.
- Tsuas yog -hauv- lub sijhawm tsim khoom: Kev sib xyaw cov hnab ntim khoom nrog cov chaw tsim khoom cement tshem tawm cov khoom muag ntau dhau- cov hnab ntim tsis tau muag / hnub nyoog (uas tuaj yeem degrade thiab ua pov tseg) raug zam, thiab kev tsim khoom raug ntsuas raws li qhov xav tau tiag tiag.

Mitigates "Downstream" khib nyiab los ntawm Extending Sack Lifespan
Kev lag luam ncig ua haujlwm tseem ceeb rau kev nthuav dav kev ua haujlwm ntawm cov ntawv cement sacks, raws li cov hnab ntim tsawg dua=cov khoom siv raw khoom pov tseg tsawg dua thiab qis dua - siv pov tseg tag nrho.
- Durability engineering: Cov hnab ntim khoom yog tsim los nrog ntau dua -cov khoom siv rov ua dua tshiab / cov ntaub ntawv nkauj nkauj zoo nkauj thiab kev tsim kho kom tiv thaiv kev tawg thaum tuav / thauj -qhov no txo cov hnab ntim puas (uas ua pov tseg) thaum siv, thiab tseem tso cai rau rov siv dua cov khoom tsis raug puas ntsoog, cov hnab ntim me me (piv txwv li, rau qhov chaw tsis muaj ntawv pov tseg) {4}.
- Kev kho kom zoo: Cov qauv tsim yooj yim (xws li, re- kaw lub valve kaw, patchable seams) pab rau - qhov chaw kho cov hnab ntim me me, ncua kev siv thiab tshem tawm qhov yuav tsum tau muab cov hnab ntim khoom pov tseg.
