Thaum Lub Peb Hlis 2022, Lub Rooj Sib Tham Thib Tsib ntawm UN Ib puag ncig txuas ntxiv mus dhau "Plastic Pollution Resolution (Draft)" ntawm Nairobi, Kenya lub peev. Nyob rau ntawm lub rooj sib tham, tus thawj coj ntawm lub xeev, ib puag ncig Minister thiab lwm tus neeg sawv cev ntawm 175 lub teb chaws tau kos npe rau qhov keeb kwm no. Qhov kev daws teeb meem yog txhawm rau txhawb kev tswj hwm thoob ntiaj teb ntawm kev txo qis cov pa phem thiab cia siab tias yuav xaus cov pa phem yas los ntawm 2024.
Kev saib xyuas ntawm cov khoom degradable
Raws li tsab ntawv ceeb toom ib puag ncig yav dhau los tso tawm los ntawm OECD (Lub Koom Haum rau Kev Sib Koom Tes Kev Lag Luam thiab Kev Tsim Kho), xyoo 2019, txhua xyoo cov khoom tsim tawm thoob ntiaj teb yog kwv yees li 460 lab tons, thiab txhua xyoo cov khib nyiab yas tau mus txog 353 lab tons. Kev tsim khoom, suav nrog cov ntim yas (40%), cov khoom siv yas (12), textiles (11%), thiab lwm yam.
Nrog rau kev txhim kho cov cai, cov ntaub ntawv biodegradable yuav nce ntxiv.
Kev sib tw rau lub peev xwm ntawm kev tsim khoom
Tam sim no, cov yas degradable ntawm kev ua lag luam tuaj yeem muab faib ua ob hom: "petroleum base" thiab "biological base". Qhov sib txawv ntawm ob feem ntau yog muab faib ua cov khoom siv raw. Petroleum-raws li degradable yas yog tsim los ntawm fossil zog, feem ntau muaj xws li PBS (polynoxylxylxylxyl glycol), PBAT (alcoholic glycolic glycolin thiab phenyl -dysteenol (hom polymer), PCL (polycopide), thiab lwm yam . ntawm pob kws, straw thiab lwm yam khoom siv lom neeg, feem ntau suav nrog PLA (polylactic acid) thiab PHA (polyxide alkyl).
Ntawm cov ntaub ntawv hais txog biodegradable saum toj no, piv nrog lwm cov khoom siv hauv lub cev-degradable, PLA (polyal acid) thiab PBAT cov nqi kuj tsawg, thiab cov txheej txheem tsim khoom kuj paub tab. Lwm qhov tseem ceeb ntawm cov yas yas.
Cov khoom siv raw ntawm PLA feem ntau yog pob kws thiab straw. Tom qab siv, nws tuaj yeem decomposed sai sai rau hauv carbon dioxide, dej thiab inorganic ntsev nyob rau hauv compost (kev lag luam compost) tej yam kev mob. (PLA) ntau lawm tsim ib lub voj voog carbon.
Peb yuav tsum tsim kom muaj kev paub txog kev tiv thaiv ib puag ncig thiab txo cov pa phem yas. Peblag luam wholesale thermoforming tshuab tuaj yeem tsim PLA lub rooj zaum ib zaug, kev ua haujlwm yooj yim thiab yooj yim, cov kev pabcuam ntse, uas tuaj yeem ua tau raws li koj cov kev xav tau ntau lawm.
