Yas
Yas yog tsim los ntawm roj, uas yog ib qho chaw uas tsis yog-tauj dua tshiab. Qhov no muaj ib cuab kev dejnum ntxim rau lub cheeb tsam. Yas kuj yuav tsum tau ib tug poj deal ntawm lub zog los ua.TreeHuggerqhia tias coob zog tawm tswv yim rau hauv lub hnab manufacturing txheej txheem yog hluav taws xob. Hauv lub tebchaws United States, ib nrab ntawm no lub zog los ntawm thee ntawd muaj fais fab tuaj cov zaub. Qhov no, dua, muaj ib feem tsis zoo rau lub chaw.
Uas yuav tau siv. Recycling kev txhais tau hais tias uas yeej down-cycled, uas txhais tau hais tias lawv ua kev ib cov khoom lesser-zoo tom qab txhua ub.
Kev kub ceev Polyethylene (HDPE)
Yog ib qhov tshaj uas siv thoob qab ntuj, HDPE ntseg ntau qualities, uas ua rau nws ib qho khoom rau manufacturing hnab yas yav tom ntej. Nws khaub-ncaws nyias, kuj pob tshab, dej thiab resistant kub, thiab muaj siab muaj zog tensile.
Apart from, HDPE hnab ntsib FDA USDA thiab cov zaub mov uas tuav cai, li no uas ua rau lawv xaiv nrov rau cov storing thiab muab rau neeg noj take-out thiab cov khw muag khoom.
HDPE hnab yas muaj nyob rau hauv cov khw, nhoo, khw, delis thiab tseem nyob hauv ob lub tsev storing thiab ntim cov laj thawj. HDPE tseem siv hnab khib nyiab, ib lub hnab dej/fais fab, T-shirt hnab thiab khaub ncaws hnab, thiab lwm.
Tsis ceev Polyethylene (LDPE)
Yas li no yog siv rau ib lub hnab dej/fais fab, ntim cov khoom noj khoom haus, ntim cov mov ci raws li lub hnab uas ua tau mob loj tsawv thiab stretch zog. Tab sis yog LDPE yuav tsis khov li HDPE hnab, lawv muaj peev xwm sawv storing tej yam khoom, hais mov thiab nqaij khoom.
Ntxiv thiab, cov ntshiab yas ua kom yooj yim qhia hais tias tus txheem, tas restaurateurs kom tau nyob hauv lub chaw fast-paced ntawm chav chaw.
Uas hais tias, LDPE hnab yas muaj ntau yam heev thiab yuav nrov siv nrog heat-sealing vim lawv tsis tshua muaj melting point. LDPE tau raws li lub USDA thiab FDA khoom tuav raws li kev cai thiab no tej zaum yuav siv los ua npuas qhwv.
