Puas tuaj yeem muab ob npaug -phab ntsa ntawv kub khob rov qab siv tau?

1. Vim li cas lawv thiaj li tsim los ua 'ib zaug-siv'

PE / PLA txheej txheej sab hauvob -phab ntsa ntawv kub khobsoftens me ntsis thaum raug tshav kub los yog kua. Tom qab siv thawj zaug, cov txheej txheem dej tsis zoo thiab cov nplaum nplaum ploj zuj zus, thiab rov siv dua tuaj yeem ua rau cov txheej txheem sib cais hauv lub khob phab ntsa lossis cov kab nrib pleb hauv qab. Ib yam li cov duab los qhia ntau zaus ua nkig, cov khoom thauj - cov kabmob muaj peev xwm ntawm ob - cov ntawv phab ntsa kub khob ua rau tsis muaj zog nrog kev siv dua. Tuav lub khob ntim nrog dej kub tuaj yeem ua rau kub hnyiab vim lub khob lub cev tawg. Qhov kev txhawj xeeb tseem ceeb tshaj plaws yog kev noj qab haus huv- ntsig txog: cov ntawv fibers hauv lub khob tsim qhov khoob tom qab siv. Yog hais tias lub khob muaj cov dej haus xws li mis nyuj tshuaj yej, qab zib residues yuav nyob twj ywm rau saum npoo thiab yuav nyuaj rau ntxuav.

2. Kev pheej hmoo ntawm kev yuam rov siv dua

Thaum muaj cov dej kub kub, qhov kub thiab txias ua kom lub zog tawg ntawm cov txheej txheej sab hauvob -phab ntsa ntawv kub khob, thiab pluag- khob zoo yuav tso microplastics. Thaum ntim cov dej txias, cov dej sib xyaw rau sab nraud ntawm lub khob tuaj yeem ua rau nws mos, ua rau nws tsis ruaj khov rau ntawm qhov chaw, zoo li 'dunkard uas tsis tuaj yeem sawv ntsug,' yooj yim tipping. Cov kev sim tau pom tias tom qab rov siv lub khob rau ob teev, hauv qab lub load -cov kabmob muaj peev xwm txo qis los ntawm 40%, thiab nws tuaj yeem 'xws' nrog lub teeb kov xwb. Yog tias koj ua lej, koj yuav pom tias ib khob nqi tsuas yog ob peb xees xwb, thiab cov nyiaj khaws tseg yuav tsis ua rau koj nplua nuj, tab sis nws tuaj yeem rhuav koj cov khaub ncaws lossis ua rau koj lub plab. Qhov no yog tiag tiag 'saib daim duab loj rau cov ntsiab lus me.'

Tus tsim ntawmmuab ob npaug rau-phab ntsa ntawv kub khobyog txhais tau tias yog 'siv thiab muab pov tseg.' Kev hais kom rov siv lawv dua yog zoo li kev twv txiaj nrog koj kev noj qab haus huv. Hloov mus rau lub khob ruaj khov yog qhov ua tau zoo dua. Tom qab tag nrho, tsis muaj leej twg xav txaus siab rau 'pob xwm txheej' tsuas yog txuag ob peb xees, txoj cai?
