Cov hnab yas uas tsis yog{0}} puas tuaj yeem rov ua dua tshiab?

Qhov nyuaj ntawm kev rov ua dua tshiab yog vim muaj txiaj ntsig kev lag luam thiab lwm yam.Plastic raws li nws cov khoom sib txawv tuaj yeem muab faib ua cov yas thermoplastic thiab thermosetting yas ob pawg.Thermosetting thiab thermoplastic plastics zoo li qhov sib txawv ntawm ceramic thiab iav, tom qab cua sov tsis tuaj yeem yaj, tom qab lwm qhov cua sov kuj tuaj yeem yaj, qhov no ua rau cov thermoplastics tuaj yeem rov qab siv tau yooj yim, xws li thermoplastics, ua ntej, ua ntej. PMMA, PS, PA, PE, PP, ABS, POM, PC, PPO, PPS, thiab lwm yam.Degradable plastics muab faib ua: photodegradable plastics (sib xyaw nrog photosensitizer hauv yas, yas maj decomposed nyob rau hauv tshav ntuj); Biodegradable plastics (uas tuaj yeem tawg tag mus rau hauv qis-} cov kab mob hauv cov kab mob molecular); Cov yas degradable (ntxiv cov khoom nqus dej hauv cov yas, muab pov tseg hauv dej tom qab siv tuaj yeem yaj, feem ntau yog siv rau cov khoom siv kho mob thiab kev noj qab haus huv los pab txhim kho kev puas tsuaj thiab tshuaj tua kab mob) feem ntau ntawm cov hnab yas uas tuaj yeem pom hauv khw tsis yog - cov yas thermoplastic degradable (degradable yuav tsis rov qab siv dua!), tuaj yeem rov ua dua tshiab. Txawm li cas los xij, cov khoom siv hauv tsev tsis paub meej. recyclable, non-recyclable classification is far from txaus), low recycling efficiency (cov hnab yas yog pheej yig thiab yooj yim kom tau raw cov ntaub ntawv, tus nqi siab ntawm recycling) thiab lwm yam ua rau recycling thiab recycling nyuaj, feem ntau yog tov nrog tsev neeg khib nyiab pov tseg los yog incineration kev kho mob.Tip: Txo koj siv cov hnab yas ntau npaum li cas. kev taw qhia, ua kom cov khib nyiab cais tawm, txo cov nqi ntawm cov khoom siv rov ua dua.Raise cov nqi ntawm cov hnab yas, qhia thiab txhawb kev txhim kho kev lag luam rov ua dua tshiab.

Peb tau tsom mus rau eco-cov khoom ntim cov khoom siv tau zoo rau ze li 20 xyoo. Muab PE & Biodegradable cov khoom thoob plaws ntiaj teb, xws li los ntawm ntau lub koom haum loj rau cov tuam txhab me me.
