Cov yam ntxwv no yog ib qho tseem ceeb tshwj xeeb rau lub tsev noj mov togo thawv uas yuav tsum tau siv ntau zaus thiab yog ib qho ntawm cov laj thawj tseem ceeb vim li cas PP lub tsev noj mov togo ntim tau nyiam hauv khw.

2.3 Transparency and Appearance: PS's Traditional Advantage yog qaug zog

Nyob rau hauv cov nqe lus ntawm pob tshab, PS yog ib txwm suav hais tias muaj txiaj ntsig zoo, tab sis nrog kev nce qib thev naus laus zis, qhov sib txawv no yog nqaim.

PS qhov zoo dua qhov pom tseeb yog ib qho ntawm nws cov khoom muag. PS yog cov yas tawv, feem ntau tsis muaj xim thiab pob tshab, zoo ib yam li iav. Polystyrene (PS) molecules muaj ntau lub nplhaib benzene, ua rau lawv tiv taus crystallization. Lawv feem ntau tsis muaj xim, pob tshab, thiab iav -zoo li, thiab tsis yog - tshuaj lom thiab tsw ntxhiab. Qhov siab pob tshab no tso cai rau PS noj su kom pom tseeb cov zaub mov sab hauv, ua rau cov neeg siv khoom txaus siab rau qhov xav tau ntawm cov khoom noj.

3.1 Tsoom Fwv Teb Chaws Txoj Cai Lij Choj

Hauv Tebchaws Meskas, txawm hais tias tsoomfwv txwv tsis pub siv polystyrene tseem tsis tau tshaj tawm, cov txheej txheem tseem ceeb ntawm txoj cai tau maj mam txhim kho, tsim kom muaj ib puag ncig zoo rau kev txhawb nqa PP lub tsev noj mov togo ntim.

FDA cov qauv kev nyab xeeb khoom noj muaj cov cai nruj rau ob qho tib si PP thiab PS lub tsev noj mov togo ntim. US FDA CFR 21 Tshooj 177 yog ib txoj cai tseem ceeb rau cov ntim khoom noj ceev uas siv tau, npog cov khoom siv kev nyab xeeb thiab ua raws. Cov qauv no suav nrog ntau yam ntaub ntawv yas, xws li polystyrene (PS), polypropylene (PP), thiab polyethylene (PE). Raws li FDA CFR 21 Tshooj 177, PS cov ntaub ntawv xav tau ntau yam kev sim, xws li styrene monomer migration theem yuav tsum tau tswj qis dua 0.05 mg / dL.

Nws yog tsim nyog sau cia tias FDA muaj qib siab dua ntawm kev pom zoo rau cov ntaub ntawv PP. PP cov ntaub ntawv tau ntawv pov thawj thoob ntiaj teb raws li kev nyab xeeb rau kev sib cuag cov zaub mov ncaj qha xws li cov tsev noj mov togo cov thawv pov tseg, ua kom cov neeg siv khoom muaj kev nyab xeeb. US FDA 21 CFR §177.1520 pom zoo PP rau kev sib cuag cov zaub mov ncaj qha thiab rau cov thawv cua sov microwave. Qhov kev pom zoo no muab kev tso cai rov qab rau kev lag luam nce qib ntawm PP ntim khoom noj.

Hais txog ib puag ncig txoj cai, US Environmental Protection Agency (EPA) tau tshaj tawm "National Strategy to Prevent Plastic Pollution," tsom rau kev tshem tawm cov pa phem hauv ib puag ncig. Thaum lub tswv yim no tsis ncaj qha rau PP lossis PS cov thawv ntim khoom noj, nws muab txoj hauv kev rau cov xeev los tsim cov cai nruj dua.

3.2 Lub Xeev- Qib txwv: Qhov Chaw Ciaj sia nyob rau PS zaub mov ntim qis

Lub xeev - theem txwv ntawm polystyrene tau nthuav dav sai, dhau los ua txoj cai tseem ceeb tshaj plaws uas ua rau hloov PS zaub ntim ntim nrog PP.

Raws li lub Tsib Hlis 2025, tsawg kawg 12 lub xeev tau siv cov tshuaj tiv thaiv polystyrene. California yog qhov tseem ceeb, nrog rau California Lub Tsev Haujlwm Saib Xyuas Kev Siv Khoom Siv thiab Rov Siv Rov Qab (CalRecycle) tshaj tawm kev txwv tsis pub muag, kev faib tawm, lossis kev ntshuam cov khoom noj khoom haus nthuav dav polystyrene (EPS) cov khoom siv, xws li cov thawv ntim khoom pov tseg thiab khob, hauv California. Xyoo 2022, Kalifonias tau dhau Txoj Cai Tiv Thaiv Plastic Pollution and Packaging Producer Responsibility Act (SB 54), xav kom cov tuam txhab tsim khoom siv khoom noj khoom haus nthuav dav polystyrene (EPS) rau tub yees, faib, lossis xa lawv mus rau hauv lub xeev tshwj tsis yog lawv tau lees paub rau lub xeev tias tag nrho EPS ua tau raws li cov kev xav tau tshwj xeeb.

Lub xeev Washington tau siv EPS lub rooj zaum rooj txiav npluav nyob rau lub Rau Hli 2023, xav kom ntim khoom ua lag luam compostable lossis recyclable. Thaum Lub Tsib Hlis 8, 2025, Oregon tus tswv xeev tau kos npe rau kev txwv tsis pub cov thawv ntim polystyrene ua npuas ncauj, ua rau lub xeev thib cuaj hauv Asmeskas txwv tsis pub siv, muag, thiab faib cov thawv polystyrene ua npuas ncauj.

New York State qhov kev txwv, pib txij Lub Ib Hlis 1, 2026, txwv tsis pub siv cov thawv ntim polystyrene nthuav dav (xws li, tab sis tsis txwv rau, cov thawv txias thiab cov dej khov nab kuab) uas tsis nyob hauv cov thawv ntim ntau dua lossis tsim los yog npaj rau cov tub yees.

Lwm lub xeev kuj maj mam siv cov kev txwv. Delaware yuav txwv tsis pub cov khw noj mov thiab kev lag luam los ntawm kev siv cov thawv polystyrene ua npuas ncauj (Foam Plastic) los npaj ua ntej-- noj zaub mov lossis dej haus. Virginia txoj kev txwv rau ib leeg - siv cov thawv ntim polystyrene (EPS) nthuav dav yuav raug siv nyob rau hauv ob theem: cov neeg muag khoom noj nrog 20 lossis ntau lub khw hauv Virginia yuav tsum ua raws li Lub Xya Hli 1, 2025, thaum tag nrho lwm cov neeg muab khoom noj yuav tsum ua raws li Lub Xya Hli 1, 2026.
