Tshawb nrhiav kev sib koom ua ke ntawm kev lag luam nkauj xwb thiab rov ua dua tshiab

Nyob rau hauv lub xyoo tom ntej, recycled PET thiab polyolefins yuav tau mus txuas ntxiv kev sib tw nrog pheej yig nkauj xwb yas.Tab sis cov khoom seem yuav raug cuam tshuam los ntawm tsoomfwv cov cai tsis meej thiab cov tswv lag luam txiav txim siab.

Cov no yog ob peb ntawm kev coj mus los ntawm kev lag luam txhua xyoo ntawm 2019 Plastics Recycling Conference thiab Trade Show, muaj nyob rau hauv Lub Peb Hlis hauv National Harbor, Md. Thaum lub sij hawm plenary, Joel Morales thiab Tison Keel, ob qho tib si ntawm kev sib koom ua lag luam IHS Markit, sib tham. kev lag luam dynamics rau cov yas yas thiab piav qhia tias cov yam tseem ceeb no yuav ua rau cov khoom siv tau zoo li cas.

Hauv kev sib tham txog PET kev lag luam, Keel siv cov duab ntawm ntau yam sib koom ua ke los tsim kom muaj cua daj cua dub zoo meej.

"Nws yog tus neeg muag khoom lag luam hauv 2018 rau ntau qhov laj thawj uas peb tuaj yeem sib tham, tab sis peb rov qab mus rau hauv lub khw muag khoom dua," Keel hais rau cov neeg coob coob."Tab sis lo lus nug kuv tab tom nug kuv tus kheej thiab peb txhua tus yuav tsum nug peb tus kheej yog, 'Yuav ua li cas rov ua dua lub luag haujlwm yuav ua rau qhov ntawd?Yog tias muaj cua daj cua dub, kev rov ua dua tshiab puas yuav pab ua kom dej txias, lossis nws puas yuav ua rau cov dej ... muaj feem cuam tshuam ntau dua?'

Morales thiab Keel kuj tau lees paub ntau yam uas nyuaj rau kwv yees, suav nrog tsoomfwv txoj cai tswjfwm kev ruaj ntseg, tus tswv lag luam kev txiav txim siab, tshuaj siv tshuaj siv thev naus laus zis thiab ntau dua.

Ob peb lub ntsiab lus tseem ceeb tau sib tham thaum lub sijhawm nthuav qhia xyoo no tau hais txog cov neeg tshawb nrhiav hauv lub vaj huam sib luag ntawm qhov kev tshwm sim 2018.

Cais, lig lub hli dhau los, Plastics Recycling Update tau sau txog ib qho kev nthuav qhia ntawm lub vaj huam sib luag los ntawm Chris Cui, tus thawj coj ntawm Tuam Tshoj Cov Kev Pabcuam rau Cov Neeg Koom Tes kaw.Nws tham txog kev lag luam kev lag luam thiab kev sib koom ua lag luam ntawm Tuam Tshoj thiab Asmeskas

Polyethylene: Morales piav qhia yuav ua li cas kev txhim kho thev naus laus zis hauv fossil fuels extraction hauv 2008 lub sijhawm ua rau muaj kev txhawb nqa ntau lawm thiab poob nqi rau cov roj ntuj.Yog li ntawd, cov tuam txhab petrochemicals tau nqis peev hauv cov nroj tsuag rau kev tsim PE.

Morales, tus thawj coj loj ntawm polyolefins rau North America tau hais tias "Muaj kev nqis peev tseem ceeb hauv cov saw hlau polyethylene raws li kev cia siab pheej yig ntawm ethane, uas yog cov kua roj ntsha ntuj," said Morales, tus thawj coj loj ntawm polyolefins rau North America.Lub tswv yim tom qab cov kev nqis peev no yog xa tawm PE nkauj xwb los ntawm Asmeskas

Tus nqi kom zoo dua ntawm cov roj ntuj tshaj cov roj tau nqaim txij li thaum, tab sis IHS Markit tseem kwv yees qhov zoo dua mus tom ntej, nws hais.

Hauv 2017 thiab 2018, kev thov thoob ntiaj teb rau PE, tshwj xeeb tshaj yog los ntawm Tuam Tshoj, tau nce ntxiv.Nws tau raug tsav los ntawm Tuam Tshoj txoj kev txwv rau kev xa rov qab PE ntshuam, nws hais tias, thiab lub teb chaws txoj cai siv cov pa roj huv huv ntau dua rau cua sov (qhov kawg xa cov kev thov rau HDPE kav los ntawm lub ru tsev).Morales tau hais tias qhov kev loj hlob ntawm kev thov tau qis dua, tab sis tau kwv yees tias yuav nyob twj ywm zoo nkauj.

Nws tau kov rau US-Tuam Tshoj kev lag luam ua tsov ua rog, hu Tuam Tshoj tus nqi se rau US prime plastics "kev puas tsuaj rau US polyethylene producers."IHS Markit kwv yees tias txij li Lub Yim Hli 23, thaum lub luag haujlwm tau pib siv, cov neeg tsim khoom tau poob 3-5 xees ib phaus ntawm txhua phaus lawv tsim, txiav rau hauv cov nyiaj tau los.Lub tuam txhab tau kwv yees hauv nws cov kev kwv yees tias cov nqi se yuav raug tshem tawm los ntawm 2020.

Xyoo tas los, kev thov rau PE yog qhov loj heev hauv Teb Chaws Asmeskas, tau tsav los ntawm tus nqi qis ntawm cov yas, muaj zog tag nrho GDP kev loj hlob, Ua nyob rau hauv America cov phiaj xwm thiab tariffs txhawb kev hloov pauv hauv tsev, cov yeeb nkab ua lag luam muaj zog vim kev nqis peev roj, nag xob nag cua Harvey tsav xav tau cov kav dej. , txhim kho PE kev sib tw piv rau PET thiab PP thiab tsoomfwv txoj cai lij choj them se txhawb nqa kev nqis peev hauv tshuab, Morales tau hais.

Saib rau pem hauv ntej ntawm kev tsim khoom tseem ceeb, 2019 yuav yog ib xyoo ntawm kev thov kom tau txais cov khoom, nws hais tias, uas txhais tau hais tias tus nqi yuav poob qis.Tab sis lawv kuj tsis xav tias yuav nce siab.Hauv 2020, lwm nthwv dej ntawm cov nroj tsuag muaj peev xwm los ntawm online, thawb cov khoom zoo tshaj qhov xav tau.

"Qhov no txhais li cas?"Morales nug."Los ntawm qhov kev xav ntawm resin-muag muag, nws txhais tau hais tias koj lub peev xwm los nce nqi thiab cov paj laum yog qhov nyuaj.[Rau] tus neeg yuav khoom tseem ceeb, nws yog lub sijhawm zoo los yuav. "

Kev lag luam yas rov ua dua tshiab yog hom daig hauv nruab nrab, nws hais.Nws tau hais nrog cov neeg siv khoom rov qab uas nws cov khoom yuav tsum tau sib tw nrog cov pheej yig heev, tsis muaj qib dav-spec PE.Nws cia siab tias kev muag khoom yuav nyob twj ywm raws li lawv niaj hnub no, nws hais.

"Muaj kev nqis peev tseem ceeb hauv cov saw hlau polyethylene raws li kev cia siab pheej yig ntawm ethane, uas yog cov kua roj ntsha ntuj," - Joel Morales, IHS Markit

Qhov hnyav dua los kwv yees yog qhov cuam tshuam ntawm tsoomfwv cov cai, xws li kev txwv thoob ntiaj teb rau lub hnab, cov quav cab thiab lwm yam khoom siv ib zaug.Lub zog ruaj khov tuaj yeem txo cov kev xav tau ntawm cov resin, tab sis nws kuj tseem tuaj yeem txhawb qee qhov kev thov rau cov tshuaj nrog rau kev rov ua dua tshiab, nws hais.

Piv txwv li, California txoj cai lij choj txwv lub hnab nyias nyias tau ua rau cov txheej txheem ua kom cov khoom tuab dua.Cov lus IHS Markit tau txais yog cov neeg siv khoom, es tsis txhob ntxuav thiab rov siv lub hnab tuab dua kaum ob zaug, tab tom ua haujlwm rau lawv li cov khib nyiab tuaj yeem, txawm li cas los xij."Yog li, nyob rau hauv cov ntaub ntawv ntawd, rov ua dua tau nce polyethylene xav tau," nws hais.

Lwm qhov, xws li hauv Argentina, lub hnab txwv tau txwv kev lag luam rau cov neeg tsim khoom nkauj nkauj xwb PE tab sis tau txhawb nqa nws rau cov tuam txhab PP, uas muag cov yas rau cov hnab PP nonwoven, nws hais.

Polypropylene: PP tau ua lag luam nruj rau lub sijhawm ntev tab sis tab tom pib sib npaug, Morales tau hais.Hauv North America xyoo tas los, cov neeg tsim khoom tsis tuaj yeem tsim cov khoom txaus kom txaus siab rau qhov kev thov, tab sis kev lag luam tseem loj hlob ntawm 3 feem pua.Qhov ntawd yog vim tias kev xa khoom tuaj puv qhov sib txawv ntawm li 10 feem pua ​​​​ntawm kev thov, nws hais.

Tab sis qhov tsis txaus ntseeg yuav tsum yooj yim nrog cov khoom lag luam nce ntxiv hauv 2019. Rau ib qho, tsis muaj "freakish freeze" thaum Lub Ib Hlis Ntuj hauv Gulf ntug dej hiav txwv zoo li xyoo 2018, nws tau sau tseg, thiab cov khoom noj khoom haus propylene tau nce.Tsis tas li ntawd, PP cov neeg tsim khoom tau nrhiav txoj hauv kev los de-bottleneck thiab ua kom muaj peev xwm ntau lawm.IHS Markit ua haujlwm txog 1 billion phaus ntawm kev tsim khoom kom tuaj online hauv North America.Yog li ntawd, lawv cia siab tias yuav pom qhov nqaim ntawm tus nqi sib txawv ntawm pheej yig dua Suav PP thiab PP hauv tsev.

"Kuv paub tias yog ib qho teeb meem rau qee tus neeg hauv kev rov ua dua tshiab vim tias, tam sim no, dav-spec PP thiab cov khoom lag luam zoo tshaj PP tau tshwm sim ntawm tus nqi thiab ntawm qhov chaw [qhov twg] koj yuav tau ua lag luam," Morales tau hais."Qhov ntawd tej zaum yuav yog ib puag ncig koj yuav ntsib feem ntau ntawm 2019."

Keel, tus thawj coj laus ntawm PET, PTA thiab EO derivatives hais tias Virgin PET thiab cov tshuaj uas nkag mus rau hauv nws yog oversuplied ntau npaum li PE.

Raws li qhov tshwm sim, "nws tsis paub meej tias leej twg yuav yog tus yeej thiab poob hauv kev lag luam PET rov ua dua," nws hais rau cov neeg tuaj saib.

Thoob ntiaj teb, kev thov PET nkauj xwb yog 78 feem pua ​​​​ntawm cov peev txheej tsim khoom.Hauv cov khoom lag luam polymers kev lag luam, yog tias qhov kev thov tsawg dua 85 feem pua, kev ua lag luam tej zaum yuav muaj ntau dhau, ua rau nws nyuaj kom tau txais txiaj ntsig, Keel tau hais.

"Qhov xwm txheej zoo tshaj plaws yog tus nqi tsim khoom RPET yuav tiaj tus, tuaj yeem siab dua.Txawm li cas los xij, nws yog siab dua tus nqi rau PET nkauj xwb.Puas yog cov neeg siv khoom ntawm RPET, uas tau tso tawm qee lub hom phiaj zoo nkauj ntawm cov khoom siv rov ua dua tshiab hauv lawv cov thawv, lawv puas kam them cov nqi siab dua no?- Tison Keel, IHS Markit

Kev thov hauv tsev yog qhov tiaj tus.Kev lag luam carbonated dej qab zib tau txo qis tab sis kev loj hlob hauv lub raj mis tsuas yog txaus los cuam tshuam qhov ntawd, Keel tau hais.

Qhov kev xav tau-kev tsis txaus siab yuav tsum tau ua phem dua nrog cov peev txheej ntau lawm los ntawm online.Nws tau hais tias "Qhov peb tau los hauv ob peb xyoos tom ntej no yog kev tsim kho loj heev," nws hais.

Keel tau hais tias cov tuam txhab lag luam ua yeeb yam tsis txaus ntseeg thiab nws tau hais tias lawv yuav tsum kaw lub peev xwm tsim khoom los nqa cov khoom siv thiab kev xav tau rau hauv kev sib npaug zoo dua;txawm li cas los xij, tsis muaj leej twg tau tshaj tawm cov phiaj xwm ua li ntawd.Lub tuam txhab Italian tshuaj Mossi Ghisolfi (M&G) tau sim tsim nws txoj hauv kev tawm ntawm cov xwm txheej los ntawm kev txhim kho tus tsiaj loj loj thiab PTA cog hauv Corpus Christi, Texas, tab sis qis qis thiab qhov project nqi overruns poob rau lub tuam txhab thaum xyoo 2017. Ib qho kev sib koom tes hu ua Corpus Christi Polymers pom zoo yuav qhov project thiab coj nws hauv online.

Keel tau sau tseg tias kev ntshuam tau ua rau tus nqi qis dua.Teb Chaws Asmeskas tau tsis tu ncua import ntau thiab ntau tus thawj PET.Cov neeg tsim khoom hauv tsev tau sim ua kom tsis txhob muaj kev sib tw txawv teb chaws nrog kev tsis txaus siab tiv thaiv kev tsis txaus siab rau tsoomfwv.Anti-dumping lub luag hauj lwm tau hloov lub hauv paus ntawm tus PET thawj - nws txo qhov ntim los ntawm Tuam Tshoj, piv txwv li - tab sis tsis tuaj yeem ua rau qeeb tag nrho qhov hnyav tuaj txog ntawm US cov chaw nres nkoj, nws hais.

Daim duab tag nrho cov khoom-xav tau yuav txhais tau tias pheej yig tus nqi PET tsis tu ncua nyob rau xyoo tom ntej, Keel tau hais.Qhov ntawd yog qhov kev sib tw ntsib PET reclaimers.

Cov neeg tsim khoom ntawm lub raj mis-qib RPET yuav tsum muaj cov nqi kho kom zoo los ua lawv cov khoom, nws hais.

Keel tau hais tias "Qhov xwm txheej zoo tshaj plaws yog tus nqi tsim khoom RPET yuav tsum tiaj tus, tuaj yeem siab dua," Keel hais.“Txawm li cas los xij, nws siab dua tus nqi rau tus tsiaj PET.Puas yog cov neeg siv khoom ntawm RPET, uas tau tso tawm qee lub hom phiaj zoo nkauj ntawm cov khoom siv rov ua dua tshiab hauv lawv cov thawv, lawv puas kam them cov nqi siab dua?Kuv tsis yog hais tias lawv yuav tsis.Keeb kwm, hauv North America, lawv tsis muaj.Hauv Tebchaws Europe, tam sim no lawv muaj ntau qhov laj thawj - qhov txawv txav ntau dua li cov neeg tsav tsheb hauv Asmeskas Tab sis qhov no yog lo lus nug loj uas tseem yuav tau teb. "

Hais txog kev rov ua dua lub raj mis-rau-lub raj mis, lwm qhov kev sib tw rau cov hom dej haus yog qhov "tsis muaj qab hau" los ntawm kev lag luam fiber ntau rau RPET, Keel tau hais.Qhov kev lag luam ntawd siv ntau tshaj peb-plaub ntawm RPET uas tsim txhua xyoo.Tus neeg tsav tsheb tsuas yog tus nqi: Nws yog qhov pheej yig dua los tsim cov khoom siv fiber ntau los ntawm PET zoo dua li cov ntaub ntawv nkauj xwb, nws hais.

Kev tsim kho tshiab los saib yog qhov tseem ceeb PET kev lag luam aggressively integrating mechanical recycling peev.Raws li cov piv txwv, xyoo no DAK Americas tau yuav Perpetual Recycling Solutions PET recycling plant hauv Indiana, thiab Indorama Ventures tau txais Custom Polymers PET cog hauv Alabama.Keel tau hais tias "Kuv yuav xav tsis thoob yog tias peb tsis pom ntau qhov haujlwm no," Keel hais.

Keel tau hais tias cov tswv tshiab yuav xav tias yuav pub cov kua dej huv rau hauv lawv cov khoom siv yaj-theem resin kom lawv tuaj yeem muab cov tswv lag luam rau cov khoom siv rov ua dua tshiab.Qhov ntawd yuav, nyob rau lub sijhawm luv luv, txo tus nqi ntawm lub raj mis-qib RPET ntawm lub khw muag khoom, nws hais.

Petrochemical tuam txhab uas muag tseem tab tom nqis peev hauv depolymerization technologies rau cov khoom siv PET.Indorama, piv txwv li, tau koom tes nrog PET tshuaj rov ua dua tshiab hauv Europe thiab North America.Cov txheej txheem rov ua dua tshiab, yog tias muaj peev xwm ua tau zoo thiab kev lag luam, tuaj yeem cuam tshuam kev lag luam loj hauv 8 mus rau 10-xyoo qab ntug, Keel tau kwv yees.

Tab sis ib qho teeb meem nyob ib puag ncig yog qis qis PET sau tus nqi hauv North America, tshwj xeeb yog Asmeskas, Keel tau hais.Hauv xyoo 2017, kwv yees li 29.2 feem pua ​​​​ntawm PET lub raj mis muag hauv Teb Chaws Asmeskas tau sau rau kev rov ua dua tshiab, raws li daim ntawv tshaj tawm txhua xyoo los ntawm National Association for PET Container Resources (NAPCOR) thiab Association of Plastic Recyclers (APR).Txhawm rau sib piv, tus nqi kwv yees li ntawm 58 feem pua ​​​​hauv 2017.

"Yuav ua li cas peb thiaj li ua tau raws li qhov xav tau los ntawm cov tswv lag luam thaum cov nqi sau qis qis, thiab peb yuav ua li cas thiaj li nce tau?"nws nug."Kuv tsis muaj lus teb rau qhov ntawd."

Thaum nug txog txoj cai tso nyiaj, Keel tau hais tias nws xav tias lawv ua haujlwm zoo los tiv thaiv cov khib nyiab, txhawb kev sau thiab tsim cov bales zoo dua.Yav dhau los, cov tswv lag luam haus dej haus cawv tau tawm tsam lawv, txawm li cas los xij, vim tias cov nyiaj xees ntxiv them los ntawm cov neeg siv khoom ntawm kev sau npe txo tag nrho kev muag khoom.

"Kuv tsuas yog tsis paub meej nyob rau lub sijhawm uas cov tswv lag luam loj yog los ntawm txoj cai pom ntawm txoj cai tso nyiaj.Keeb kwm, lawv tau tawm tsam txoj cai tso nyiaj, "nws hais."Txawm hais tias lawv tseem yuav tawm tsam qhov ntawd, kuv tsis tuaj yeem hais."

Daim ntawv luam tawm peb lub hlis twg ntawm Plastics Recycling Update muab cov xov xwm tshwj xeeb thiab kev tshuaj xyuas uas yuav pab txhawb nqa cov khoom siv rov ua dua tshiab.Sau npe hnub no kom paub tseeb tias koj tau txais nws ntawm koj lub tsev lossis chaw ua haujlwm.

Tus thawj coj ntawm ib lub lag luam thoob ntiaj teb lub raj mis dej loj tshaj plaws tsis ntev los no tau piav qhia txog lub tuam txhab cov tswv yim rov ua dua tshiab, ceeb toom tias nws txhawb nqa txoj cai tso nyiaj thiab lwm cov kauj ruam los txhawb cov khoom siv.

Lub tuam txhab tshuaj ntiaj teb Eastman tau nthuav tawm cov txheej txheem rov ua dua tshiab uas rhuav tshem cov polymers rau hauv cov pa roj siv rau hauv kev tsim tshuaj.Tam sim no tab tom nrhiav rau cov neeg xa khoom.

Ib txoj kab rov ua dua tshiab yuav pab tsim cov khoom noj-hu rau RPET los ntawm tsuas yog hais txog qhov qias neeg nyob ib puag ncig: lub raj mis khaws los ntawm qhov chaw pov tseg.

Cov neeg thim rov qab ntawm qhov project plastics-rau-roj nyob rau hauv Indiana tshaj tawm tias lawv tab tom npaj tawg hauv av ntawm $ 260 lab kev lag luam-scale chaw.

Tus nqi ntawm ntuj HDPE tau txuas ntxiv poob thiab tam sim no zaum zoo hauv qab nws txoj haujlwm ib xyoos dhau los, tab sis cov txiaj ntsig zoo ntawm PET tau nyob tas li.

Lub tuam txhab khaub ncaws thoob ntiaj teb H&M tau siv qhov sib npaug ntawm 325 lab PET lub raj mis hauv nws cov khoom siv polyester xyoo tas los, nce ntau ntawm xyoo ua ntej.
