Njira 4 zatsopano zopangira zinthu zopangidwa ndi pulasitiki: chikopa cha nsomba, zipolopolo zambewu ya vwende, maenje a azitona, shuga wamasamba.
Padziko lonse, mabotolo apulasitiki okwana 1.3 biliyoni amagulitsidwa tsiku lililonse, ndipo ichi ndi nsonga chabe ya mapulasitiki opangidwa ndi mafuta.Komabe, mafuta ndi gwero lachimaliziro, chosasinthika.Chodetsa nkhawa kwambiri, kugwiritsa ntchito zinthu za petrochemical kudzathandizira kutentha kwa dziko.
Chochititsa chidwi n'chakuti mbadwo watsopano wa mapulasitiki opangidwa ndi bio, opangidwa kuchokera ku zomera komanso ngakhale mamba a nsomba, akuyamba kulowa m'miyoyo yathu ndikugwira ntchito.Kusintha zinthu zamafuta a petrochemical ndi zida zotengera zachilengedwe sikungochepetsa kudalira chuma chochepa cha petrochemical, komanso kuchedwetsanso kuthamanga kwa kutentha kwa dziko.
Mapulasitiki opangidwa ndi zamoyo akutipulumutsa pang'onopang'ono kuchokera kumatope apulasitiki opangidwa ndi mafuta!
bwenzi, ukudziwa chiyani?Maenje a azitona, zigoba zambewu ya vwende, zikopa za nsomba, ndi shuga wa m’mbewu zingagwiritsidwe ntchito kupanga pulasitiki!
01 dzenje la azitona (mafuta a azitona)
Kampani yaku Turkey yotchedwa Biolive yayamba kupanga ma pellets angapo opangidwa kuchokera ku maenje a azitona, omwe amadziwikanso kuti mapulasitiki opangidwa ndi bio.
Oleuropein, chomwe chimapezeka mu njere za azitona, ndi antioxidant yomwe imatalikitsa moyo wa bioplastics ndikufulumizitsa kupanga kompositi kukhala feteleza pakatha chaka.
Chifukwa ma pellets a Biolive amagwira ntchito ngati mapulasitiki opangidwa ndi petroleum, amatha kugwiritsidwa ntchito m'malo mwa mapulasitiki wamba popanda kusokoneza kapangidwe kazinthu zamafakitale komanso kulongedza zakudya.
02 Zipolopolo za Mbeu za Mavwende
Kampani yaku Germany ya Golden Compound yapanga pulasitiki yapadera yopangidwa kuchokera ku zipolopolo zambewu ya vwende, yotchedwa S²PC, ndipo imati imatha kubwezeredwanso 100%.Zipolopolo zambewu za mavwende zosaphika, monga zotuluka pochotsa mafuta, zitha kufotokozedwa ngati mtsinje wokhazikika.
Ma S²PC bioplastics amagwiritsidwa ntchito m'magawo osiyanasiyana, kuchokera pamipando yamaofesi mpaka kunyamula zinthu zomwe zingagwiritsidwenso ntchito, mabokosi osungira ndi mabokosi.
Zogulitsa za "green Compound" za "green" bioplastic zikuphatikiza makapisozi a khofi omwe apambana kwambiri padziko lonse lapansi, mapoto amaluwa ndi makapu a khofi.
03 Chikopa cha nsomba ndi mamba
Ntchito yochokera ku UK yotchedwa MarinaTex ikugwiritsa ntchito zikopa za nsomba ndi mamba ophatikizana ndi algae ofiira kuti apange mapulasitiki opangidwa ndi bio omwe angalowe m'malo mwa mapulasitiki ogwiritsidwa ntchito kamodzi monga matumba a mkate ndi masangweji opaka masangweji ndipo akuyembekezeka kuthana ndi matani theka la miliyoni a nsomba zopangidwa. ku UK chaka chilichonse Khungu ndi mamba.
04 Bzalani shuga
Avantium yochokera ku Amsterdam yapanga ukadaulo wa "YXY" wosinthira mbewu kupita ku pulasitiki womwe umasintha mashuga opangidwa kuchokera ku mbewu kukhala chinthu chatsopano chophatikizika cha biodegradable - ethylene furandicarboxylate (PEF).
Zinthuzi zakhala zikugwiritsidwa ntchito popanga nsalu, mafilimu, ndipo zimatha kukhala zida zazikulu zopangira zakumwa zozizilitsa kukhosi, madzi, zakumwa zoledzeretsa ndi timadziti, ndipo adagwirizana ndi makampani monga Carlsberg kuti apange "100% bio-based. ” mabotolo amowa.
Kugwiritsa ntchito mapulasitiki opangidwa ndi bio ndikofunikira
Kafukufuku wawonetsa kuti zida zachilengedwe zimangotenga 1% yokha ya pulasitiki yonse, pomwe zida zamapulasitiki azikhalidwe zonse zimachokera kuzinthu zamafuta.Pofuna kuchepetsa kuwonongeka kwa chilengedwe pogwiritsa ntchito petrochemical resources, m'pofunika kugwiritsa ntchito mapulasitiki opangidwa kuchokera kuzinthu zowonjezera (zinyama ndi zomera).
Ndi kukhazikitsidwa motsatizana kwa malamulo ndi malamulo okhudza mapulasitiki opangidwa ndi bio-based m'maiko aku Europe ndi America, komanso kulengeza ziletso zapulasitiki m'magawo osiyanasiyana adzikolo.Kugwiritsiridwa ntchito kwa mapulasitiki opangidwa ndi eco-friendly bio-based kudzakhalanso kolamulirika komanso kufalikira.
Chitsimikizo chapadziko lonse lapansi chazinthu zopangidwa ndi bio
Mapulasitiki opangidwa ndi bio ndi mtundu umodzi wazinthu zopangidwa ndi bio, kotero zolemba zotsimikizira zomwe zimagwiritsidwa ntchito pazinthu zopangidwa ndi bio zimagwiranso ntchito pamapulasitiki opangidwa ndi bio.
USDA Bio-Priority Label ya USDA, UL 9798 Bio-based Content Verification Mark, OK Biobased of Belgian TÜV AUSTRIA Group, Germany DIN-Geprüft Biobased ndi Brazil Braskem Company's I'm Green, zilembo zinayizi zimayesedwa kuti zitsimikizire zamoyo.Mu ulalo woyamba, akuti njira ya kaboni 14 imagwiritsidwa ntchito pozindikira zamoyo.
USDA Bio-Priority Label ndi UL 9798 Bio-based Content Verification Mark aziwonetsa mwachindunji kuchuluka kwazomwe zili patsambalo;pomwe zolemba za OK Bio-based ndi DIN-Geprüft Bio-based zikuwonetsa pafupifupi kuchuluka kwazinthu zomwe zimapangidwa;Zolemba za I'm Green ndizogwiritsidwa ntchito ndi makasitomala a Braskem Corporation okha.
Poyerekeza ndi mapulasitiki achikhalidwe, mapulasitiki opangidwa ndi bio amangoganizira gawo lazopangira, ndikusankha zida zotengedwa ndi biologically kuti zilowe m'malo mwa petrochemicals zomwe zikukumana ndi kusowa.Ngati mukufunabe kukwaniritsa zofunikira za dongosolo lachiletso la pulasitiki, muyenera kuyambira pamapangidwe azinthu kuti mukwaniritse zomwe zingawonongeke.
