Moulded Pulp Sustainability FAQ: Compostable, Biodegradable, thiab Recyclable
Puas yog molded pulp compostable?
Yog, uncoated molded pulp yog ntawv pov thawj compostable. Nws ua tau raws li cov qauv xws li: -TS EN 13432(European standard for compostable ntim) -ASTM D 6400 3(US tus qauv rau compostable plastics) -BPI(Biodegradable Products Institute ntawv pov thawj) -TÜV Austria OK Compost(Industrial and Home Compost)
Nyob rau hauv cov chaw muaj composting (55-70 degree, tswj cov dej noo), molded pulp tawg tsis pub dhau 30-90 hnub. Hauv tsev compost, nws feem ntau siv 3-6 lub hlis.
Puas yog molded pulp biodegradable?
Yog lawm. Moulded pulp yog tsim los ntawm cellulose fibers, uas yog ib txwm biodegradable. Cov kab mob (cov kab mob, cov kab mob fungi) rhuav tshem cellulose rau hauv carbon dioxide, dej, thiab biomass. Tsis zoo li "biodegradable plastics" uas yuav tawg mus rau hauv microplastics, molded pulp decomposes tag nrho ntawm molecular qib.
Biodegradation ncua sij hawm: -Industrial compost: 30-90 hnub -Lub tsev compost: 3 -6 lub hlis -Av faus: 2-6 lub hlis -Marine ib puag ncig: 6-18 lub hlis (hloov vim qhov ua haujlwm ntawm microbial qis)
Puas yog moulded pulp recyclable?
Yog lawm. Moulded pulp yog recyclable nyob rau hauv cov qauv ntawv recycling kwj. Nws tuaj yeem rov ua dua mus txog 5-7 zaug ua ntej fibers yuav luv dhau. Feem ntau curbside recycling cov kev pab cuam txais molded pulp khoom. Tshawb xyuas cov lus qhia hauv zos, vim qee qhov chaw yuav tsis txais cov khoom noj uas muaj av.
Dab tsi yog carbon footprint ntawm molded pulp?
Moulded pulp muaj cov pa roj carbon tsawg dua li cov ntim yas: -Cog -raws li fibersnqus CO2 thaum loj hlob (biogenic carbon) -Cov ntsiab lus rov siv duazam emissions los ntawm cov khoom siv nkauj xwb -Tsawg zogmanufacturing piv rau yas extrusion/injection -Tsis muaj fossil carbontso tawm thaum decomposition
Cov kev tshawb fawb pom tias molded pulp tuaj yeem txo cov ntim cov pa roj carbon emissions los ntawm 40-70% piv rau cov khoom ntim yas sib npaug los yog ua npuas ncauj.
Puas molded pulp muaj PFAS?
Ib txwm molded pulp rau kev pabcuam zaub mov qee zaum siv PFAS (ib - thiab polyfluoroalkyl tshuaj) rau roj thiab dej tsis kam. Txawm li cas los xij, niaj hnub manufacturers muajPFAS{0}}dawblwm txoj kev siv: -Chitosan(shellfish- muab tau biopolymer) -Shellac(natural resin) -Cog waxes(soy, xibtes, carnauba) -Cov hmoov txhuv nplej siab-raws li txheej - AKD/ASA(alkyl ketene dimer, alkenyl succinic anhydride)
Ib txwm nug cov neeg xa khoom rau PFAS- ntawv pov thawj pub dawb, raws li cov cai (US EPA, EU REACH) tau txwv ntau ntxiv rau PFAS.
Puas yog molded pulp ntim zaub mov- nyab xeeb?
Yog lawm, thaum tsim khoom nrog zaub mov - cov ntaub ntawv qib thiab ua kom raug. Cov ntawv pov thawj tseem ceeb: -FDA 21 CFR(US Food and Drug Administration) -LFGB(German Food and Feed Code) -BfR(German Federal Institute for Risk Assessment) -EFSA(European Food Safety Authority)
Khoom noj khoom haus-kev nyab xeeb molded pulp siv: - nkauj xwb los yog huv si siv fibers (tsis muaj post-cov neeg siv khoom pov tseg rau cov khoom noj muaj roj ncaj qha) - Khoom noj khoom haus- qib additives thiab pigments - PFAS-dawb barrier coatings - Clean manufacturing puag ncig
Puas tuaj yeem molded pulp siv rau cov khoom noj ntub lossis roj?
Yog, nrog cov txheej txheem tsim nyog: -Dej tsis kam: AKD, ASA, lossis wax coatings -Roj kuj: Chitosan, shellac, los yog starch -raws li txheej txheej -Ob leeg: Multi- txheej bio-raws li txheej txheej
Coated molded pulp tuaj yeem ua tau: - Cov dej kub thiab txias - Cov khoom noj roj (fries, burgers) - Cov khoom ntub dej - Cov kua zaub thiab kua ntses (nrog lub hau tsim nyog)
Yuav ua li cas molded pulp piv rau yas nyob rau hauv sustainability?
| Yam | Moulded Pulp | Yas (PET / PS / EPS) |
|---|---|---|
| Cov khoom nyoos | Recycled/renewable | Petroleum (zeeg) |
| Rov ua dua | Yog (paper kwj) | Txwv (nyob ntawm hom) |
| Compostable | Yog lawm | Tsis muaj |
| Biodegradable | Yog lawm | Tsis yog (persists centuries) |
| Cov pa roj carbon footprint | Tsawg | Siab |
| Microplastic kev pheej hmoo | Tsis muaj | Siab |
| Zog tsim | Nruab nrab | Siab |
| Xaus - ntawm - txoj kev ua neej | Recycle, compost, pov tseg | Rov ua dua (tsis tshua muaj), pov tseg, hlawv |
Kuv yuav nrhiav tau ntawv pov thawj dab tsi?
Compostability: - BPI (Biodegradable Products Institute) - TÜV Austria OK Compost (Industrial/Home) - DIN CERTCO (European compostability)
Kev Nyab Xeeb Khoom Noj: - FDA (US) - LFGB (Lub Tebchaws Yelemees/EU) - BfR (Lub Tebchaws Yelemees)
Sustainable Sourcing: - FSC (Forest Stewardship Council) - PEFC (Programme for the Endorsement of Forest Certification)
Kev Tswj Xyuas Zoo: - ISO 9001 (Quality) - ISO 14001 (Environmental) - BRCGS (Cov khoom ntim thiab ntim khoom)
Puas yog bagasse molded pulp muaj kev ruaj ntseg dua li cov ntawv siv dua tshiab?
Ob leeg muaj kev ruaj ntseg, tab sis muaj qhov zoo sib txawv:
Bagasse (sugarcane fiber): - Ua los ntawm kev ua liaj ua teb pov tseg (qab zib residue) - Tsis sib tw nrog cov khoom noj khoom haus - Rov ua dua txhua xyoo - Cov xim sib dua (tsawg dua yuav tsum tau tshuaj dawb) - Cov npoo du rau daim ntawv thov hwm - Tej zaum yuav raug xa tuaj (khoom noj mov mais kev txiav txim siab)
Cov ntawv siv dua: - Tshem tawm cov khib nyiab los ntawm qhov chaw pov tseg - Tus nqi qis dua - Muaj dav dav - Tej zaum yuav muaj cov inks thiab cov khoom tsis huv (yuav tsum tau ntxuav) - rougher nto me ntsis
Rau ntau daim ntawv thov, ob qho tib si yog cov kev xaiv zoo tshaj plaws. Bagasse muaj kev zoo nkauj zoo nkauj, thaum cov ntawv siv dua tshiab muab cov nqi thiab cov txiaj ntsig kev lag luam ncig.
Puas tuaj yeem moulded pulp ntim rov qab siv tau?
Thaum tsim feem ntau rau ib zaug -siv, molded pulp tuaj yeem rov qab siv tau hauv qee yam kev siv: -Sturdy tuab-cov khoom siv phab ntsa: tuaj yeem rov siv tau ntau zaus yog tias khaws cia qhuav -Rov qab ntim tshuab: Qee daim ntawv thov kev lag luam siv cov khoom siv rov qab tuaj yeem molded pulp tais -Cov neeg siv khoom rov siv dua: Qe cartons feem ntau rov qab siv rau khoom siv tes ua, cia, ua teb
Txawm li cas los xij, molded pulp tsis yog tsim los rau rov ntxuav dua los yog hnyav- rov siv dua li cov ntim yas.
Yuav ua li cas rau molded pulp nyob rau hauv qhov chaw pov tseg?
Nyob rau hauv anaerobic (oxygen{0}}dawb) cov khoom pov tseg, pwm cov ntaub ntawv biodegrades qeeb dua thiab tuaj yeem tsim cov methane (cov pa roj hauv tsev cog khoom). Txawm li cas los xij, nws tseem tawg sai dua li cov yas (uas nyob rau ntau pua xyoo). Txhawm rau kom muaj txiaj ntsig zoo tshaj plaws rau ib puag ncig, ua qhov tseem ceeb ntawm kev rov ua dua lossis kev ua kom zoo dua pov tseg pov tseg.
Yuav ua li cas pov tseg ntawm molded pulp ntim?
- Rov ua dua(nyiam dua): Muab tso rau hauv daim ntawv rov ua dua tshiab (yog tias huv si thiab qhuav)
- Compost: Industrial lossis hauv tsev compost (yog tias muaj ntawv pov thawj compostable)
- Muab pov tseg: Qhov chaw kawg (tseem biodegradable, tab sis qeeb dua)
Tsis txhob: - Flush (tuaj yeem ua rau muaj teeb meem ntawm cov kav dej) - Cov khoom pov tseg (tuaj yeem tiv thaiv kev rov ua dua tshiab) - Hlawv hauv qhov tsis raug cai (tuaj yeem tso cov khoom seem)
Hesheng Innovation Development Ltd. tsim cov ntawv pov thawj compostable thiab recyclable molded pulp ntim nrog PFAS-kev xaiv pub dawb, FDA / LFGB zaub mov kev nyab xeeb ua raws, thiab FSC- tau ntawv pov thawj fiber ntau.
