Raws li tsab ntawv ceeb toom los ntawm Circular, kev hloov pauv cov kev lag luam yas tawm mus rau hauv kev lag luam thoob ntiaj teb ntsib ntau yam teeb meem. Raws li tsab ntawv ceeb toom "Plastic Discovery: Optimizing the Recycling Plastic Value Chain", daim ntawv tshaj tawm qhia txog rau lub ntsiab lus tseem ceeb ntawm kev rov ua dua tshiab, suav nrog rau 6 lub ntsiab lus tseem ceeb hauv qab no:
1.Plastics yog ib qho kev lag luam loj thiab tsim nyog, nyob ntawm ib puag ncig kev sib tshuam.
2.Sustainable txoj kev loj hlob muab ib tug undervalued economic lub sij hawm.
3.Kev hloov pauv ntawm kev ua lag luam tuaj yeem cuam tshuam ntev - lub sijhawm peev.
4.Qhov nqes hav tau tsav txoj kev loj hlob ntawm cov khoom siv rov ua dua tshiab.
5.Cov cua tsis zoo tau ua rau qeeb tus nqi ntawm cov khoom siv rov ua dua tshiab.
6.Qhov kev lag luam xav tau kev siv thev naus laus zis raws li kev daws teeb meem los ua kom tus nqi ntsuab zoo li xoom.
Daim ntawv tshaj tawm hais tias muaj ob qho tib si ib puag ncig thiab kev txhawb nqa nyiaj txiag los txhawb kev txav mus rau kev lag luam ncig. Los ntawm ib puag ncig kev xav, txo qhov kev thov rau cov yas hauv dej hiav txwv yog pom tseeb. Txawm li cas los xij, raws li tsab ntawv ceeb toom, yog tias tsis tau tsim los ntawm tus qauv kev lag luam ntau dua, cov khoom siv yas yuav tsim ntau dua 2 billion tons ntawm carbon dioxide sib npaug los ntawm 2040, sib npaug li 5% ntawm lub ntiaj teb cov pa roj carbon monoxide emissions, thiab 86% ntawm cov khoom yas yuav raug faus, hlawv lossis xau. Tsis tas li ntawd, tej zaum qhov tseem ceeb tshaj plaws yog tias Microplastics tam sim no muaj nyob hauv tib neeg lub cev. Lub Ntiaj Teb Wildlife Fund tau tshaj tawm tias tus neeg nruab nrab noj 5 grams ntawm cov yas hauv ib lub lis piam.
Tsis tas li ntawd, raws li tsab ntawv ceeb toom, muaj ntau qhov laj thawj kev lag luam vim li cas tig mus rau kev lag luam ncig tuaj yeem tseem muaj txiaj ntsig zoo rau tib neeg hauv kev lag luam yas. Kev lag luam tseem tab tom loj hlob, nrog rau kev lag luam yas thoob ntiaj teb ntawm $ 600 nphom thiab xav tias yuav loj hlob mus rau ntau dua $ 800 nphom los ntawm 2030. Tib lub sijhawm, lub ntiaj teb rov ua dua tus nqi tsawg dua 9%, thiab kev lag luam loj yog $ 50 billion. Qhov no qhia tau hais tias lub voj voog kev lag luam tsis tau tsim tag nrho rau qee qhov thiab tseem muaj qee qhov chaw rau kev loj hlob. Raws li paub zoo, kev ua lag luam rau cov khoom siv rov ua dua tshiab yog qhov tsis muaj zog heev. Raws li cov lus ceeb toom, tus nqi nruab nrab tau nce ob npaug ntawm 2020 txog 2021, thiab tom qab ntawd ib nrab ntawm 2021 txog 2022.
Raws li tsab ntawv ceeb toom thiab kev pom zoo dav dav, ntau yam ua rau qeeb qeeb ntawm kev nce qib mus rau kev lag luam tag nrho. Firstly, muaj usability. Raws li tsab ntawv ceeb toom no, cov tuam txhab nrhiav kom hloov cov yas qub nrog cov yas siv dua tshiab PCR thaum lub sijhawm tsim khoom tsis tuaj yeem nrhiav cov khoom uas lawv xav tau. Kev ua lag luam opaque thiab kev simulation tsis zoo ua rau loj - kev yuav khoom ntawm PCR nyuaj. Tsis tas li ntawd, muaj ntau qhov siab - zoo (tsawg muaj kuab paug) pov tseg yas cais, uas yog vim muaj teeb meem xav tau.
Tam sim no, tus nqi ntawm cov yas rov ua dua yog ob npaug ntawm cov yas qub, uas yog tshwm sim los ntawm kev faib tawm, kev thauj mus los, thiab cov nqi ua haujlwm, hu ua "tus nqi ntsuab". Qhov no ua rau cov lag luam loj tsis kam nqis peev hauv PCR.
Daim ntawv tshaj tawm kuj tseem hais ntxiv tias cov tuam txhab muaj kev txhawj xeeb txog kev ntseeg siab ntawm cov khoom siv rov ua dua tshiab, vim tias muaj cov impurities lossis cov kab mob sib kis hauv cov resins tom qab noj tuaj yeem cuam tshuam rau xim, lub cev, thiab tsw ntawm cov ntaub ntawv.
Nrog rau cov thev naus laus zis, WalthMac zoo heev pab cov tuam txhab txuag cov ntaub ntawv raw thiab tswj cov nqi tsim khoom hauv cov txheej txheem ntawm cov khoom xyaw thiab kev sib xyaw.https://www.walthmac.net/gravimetric-blender/gravimetric-blenders/six-types-ntawm-raw{8}}khoom siv{9}.
