TOF hu rau National Academies los Tshawb Nrhiav Kev Tsim Kho Plastics

Raws li ib feem ntawm Ocean Foundation's Redesigning Plastics Initiative, thaum Lub Xya Hli 15, 2019, peb tau thov kom muaj lub rooj sib tham los ntawm cov thawj coj tseem ceeb ntawm National Academies of Sciences, Engineering thiab Medicine suav nrog: Pawg Saib Xyuas Dej Hiav Txwv Studies, Pawg Neeg Saib Xyuas Kev Tshawb Fawb Kev Tshawb Fawb thiab Tshuab thiab. Board on Environmental Studies thiab Toxicology. TOF Thawj Tswj Hwm Mark J. Spalding, ib tug tswv cuab ntawm Pawg Saib Xyuas Kev Tshawb Fawb Dej Hiav Txwv, tau hu rau lub rooj sib tham scopeing los nug cov lus nug ntawm yuav ua li cas cov Academies tuaj yeem tawm tswv yim txog kev tshawb fawb ntawm kev tsim cov yas tshiab thiab lub peev xwm rau kev tsim khoom raws li txoj hauv kev los daws cov kev sib koom. ntiaj teb no plastic pollution challenge. 

Peb pib los ntawm kev nkag siab tias "yas tsis yog yas," thiab hais tias lub sij hawm yog ib kab lus ntawm lub kaus rau ib tug xov tooj ntawm cov khoom ua los ntawm ntau yam polymers, additives, thiab cov khoom sib xyaw. Nyob rau tib lub sijhawm peb teev, pab pawg tau sib tham txog ntau qhov kev sib tw dav los daws cov teeb meem yas, los ntawm kev rov qab los thiab rov ua dua tshiab rau cov kev tswj cov khib nyiab pov tseg thiab qhov tsis paub tseeb hauv kev tshuaj xyuas ib puag ncig txoj hmoo thiab cuam tshuam ntawm cov yas rau thaj chaw, tsiaj qus thiab tib neeg kev noj qab haus huv. . Muab TOF qhov tshwj xeeb hu rau kev nqis tes ua rau kev tshawb fawb txog kev tsim kho tshiab, txhawm rau tsav kev tsim khoom raws li txoj hauv kev, qee cov neeg koom tau sib cav tias txoj hauv kev no yuav zoo dua rau kev sib tham los ntawm txoj cai (tsis yog kev tshawb fawb txog kev tshawb fawb) los tswj kev tsim kho tshiab kom tshem tawm cov ntaub ntawv thiab cov khoom tsim complexity, txo cov kab mob, thiab txwv tsis pub muaj ntau yam ntawm polymers nyob rau hauv kev ua lag luam. Txawm hais tias kev tshawb fawb tsis paub tseeb tseem nyob hauv yuav ua li cas rov qab tau, rov siv dua, lossis rov ua dua cov yas uas twb muaj lawm ntawm qhov ntsuas, ntau tus kws tshawb fawb hauv lub rooj sib tham tau hais tias cov kws tsim khoom siv tshuaj thiab cov ntaub ntawv kws tshawb fawb tuaj yeem ua kom yooj yim thiab tsim cov qauv yas los ntawm kev sib xyaw ntawm bio-based, mechanical thiab chemical method, yog tias muaj kev txhawb siab thiab hu kom ua li ntawd.  

Tsis yog hais kom cov ntaub ntawv tshwj xeeb yuav tsum muaj nyob rau hauv plastics, lwm tus neeg koom tau qhia tias txoj hauv kev ua tau zoo yuav cuam tshuam rau kev tshawb fawb thiab kev lag luam ntiag tug kom dhau los ua tshiab thiab zam cov kev cai uas tuaj yeem tsis lees paub raws li kev sau ntawv dhau los. Qhov no tseem tuaj yeem ua rau lub qhov rooj qhib rau qhov kev tsim kho tshiab ntau dua hauv txoj kev. Thaum kawg ntawm lub hnub, cov khoom siv yooj yim thiab cov khoom siv tshiab tsuas yog ua tau zoo raws li lawv cov kev xav tau ntawm kev lag luam, yog li kev tshuaj xyuas cov nqi tsim khoom thiab ua kom cov khoom lag luam pheej yig rau cov neeg siv khoom nruab nrab yog qhov tseem ceeb sib npaug rau kev tshawb nrhiav. Cov kev sib tham hauv lub rooj sib tham tau txhawb nqa tus nqi ntawm kev koom nrog cov neeg siv khoom hauv cov khoom siv yas los pab txheeb xyuas cov kev daws teeb meem uas txhawb nqa kev txhawb nqa tsim nyog los txhawb kev siv.
