Iindlela ezi-4 ezintsha zezinto ezisetyenziswa kwiplastiki ezisekelwe kwizinto eziphilayo: ulusu lwentlanzi, amaqokobhe embewu yemelon, imingxunya yeolive, iiswekile zemifuno.
Kwihlabathi liphela, iibhotile zeplastiki eziyi-1.3 yeebhiliyoni zithengiswa yonke imihla, kwaye loo nto yingcosana nje yeplastiki esekwe kwi-petroleum. Nangona kunjalo, ioyile sisixhobo esinomda, esingavuselelekiyo. Okuxhalabisa ngakumbi kukuba, ukusetyenziswa kwezixhobo ze-petrochemical kuya kuba negalelo ekufudumaleni kwehlabathi.
Okuvuyisayo kukuba, isizukulwana esitsha seplastiki ezisekelwe kwi-bio, ezenziwe ngezityalo kwanangamaxolo eentlanzi, siqala ukungena ebomini bethu nasemsebenzini. Ukutshintsha izinto ze-petrochemical ngezinto ezisekelwe kwi-bio akuyi kunciphisa kuphela ukuxhomekeka kwizixhobo ze-petrochemical ezinqongopheleyo, kodwa kuya kunciphisa nesantya sokufudumala kwehlabathi.
Iiplastiki ezisekelwe kwibhayoloji zisisindisa inyathelo ngenyathelo kwingxaki yeeplastiki ezisekelwe kwipetroli!
Sihlobo, uyazi ntoni? Ii-olive pits, amaqokobhe embewu ye-melon, izikhumba zeentlanzi, kunye neswekile yezityalo zingasetyenziselwa ukwenza iplastiki!
01 Umngxuma weolive (imveliso engaphantsi kweoyile yomnquma)
Inkampani entsha yaseTurkey ebizwa ngokuba yiBiolive izimisele ukuphuhlisa uthotho lweepellets ze-bioplastic ezenziwe ngemigqomo yomnquma, ezaziwa ngokuba ziiplastiki ezisekelwe kwi-bio.
I-Oleuropein, isithako esisebenzayo esifumaneka kwimbewu yomnquma, sisixhobo sokulwa ne-antioxidant esandisa ubomi be-bioplastics ngelixa ikwakhawulezisa ukwenziwa komgquba wezinto zibe sisichumiso kungakapheli unyaka.
Ngenxa yokuba iipellets zeBiolive zisebenza njengeeplastiki ezisekelwe kwipetroleum, zinokusetyenziswa nje endaweni yeepellets zeplastiki eziqhelekileyo ngaphandle kokuphazamisa umjikelo wemveliso yeemveliso zoshishino kunye nokupakishwa kokutya.
02 Iigobolondo zeMbewu yeMelon
Inkampani yaseJamani iGolden Compound iphuhlise iplastiki eyahlukileyo eyenziwe ngamaqokobhe embewu yemelon, ebizwa ngokuba yi-S²PC, kwaye ithi inokuphinde isetyenziswe ngokupheleleyo. Amaqokobhe embewu yemelon eluhlaza, njengemveliso ephuma ekutsalweni kweoyile, anokuchazwa njengomlambo oqhubekayo.
Ii-bioplastics ze-S²PC zisetyenziswa kwiinkalo ezahlukeneyo, ukusuka kwifenitshala yeofisi ukuya ekuthuthweni kwezinto ezinokuphinda zisetyenziswe, iibhokisi zokugcina kunye neebhokisi.
Iimveliso ze-bioplastic zeGolden Compound “eziluhlaza” ziquka ii-capsules zekofu ezibolayo, iimbiza zeentyatyambo kunye neekomityi zekofu eziphumelele amabhaso, eziqale ukubola emhlabeni.
03 Ulusu lwentlanzi kunye namaxolo
Iphulo elise-UK elibizwa ngokuba yiMarinaTex lisebenzisa izikhumba zeentlanzi kunye namaxolo adityaniswe ne-algae ebomvu ukwenza iiplastiki ezisekelwe kwi-bio ezinokwenziwa umgquba ezinokutshintsha iiplastiki ezisetyenziswa kanye njee njengeengxowa zesonka kunye neesandwich wraps kwaye kulindeleke ukuba zijongane neetoni ezisisiqingatha sesigidi seentlanzi eziveliswa e-UK minyaka le.
04 Iswekile yezityalo
I-Avantium ese-Amsterdam iphuhlise ubuchwepheshe obutsha be-"YXY" bokutshintsha isityalo sibe yiplastiki obuguqula iswekile esekwe kwizityalo ibe zizinto ezintsha zokupakisha ezinokubola – i-ethylene furandicarboxylate (PEF).
Le nto isetyenzisiwe ekuveliseni amalaphu, iifilimu, kwaye inokuba yeyona nto iphambili ekupakisheni iziselo ezibandayo, amanzi, iziselo ezinxilisayo kunye neejusi, kwaye isebenzisana neenkampani ezifana neCarlsberg ukuphuhlisa iibhotile zebhiya "ezisekelwe kwi-100% kwibhayoloji".
Ukusetyenziswa kweplastiki esekwe kwibhayoloji kubalulekile
Izifundo zibonise ukuba izinto zebhayoloji zithatha i-1% kuphela yemveliso iyonke yeplastiki, ngelixa izinto zeplastiki zemveli zonke zivela kwiincindi ze-petrochemical. Ukuze kuncitshiswe impembelelo embi yokusetyenziswa kwezixhobo ze-petrochemical kwindalo esingqongileyo, kubalulekile ukusebenzisa iiplastiki eziveliswe kwizixhobo ezivuselelekayo (izilwanyana nezityalo).
Ngokusungulwa kwemithetho nemigaqo elandelelanayo malunga neeplastiki ezisekelwe kwibhayoloji kumazwe aseYurophu naseMelika, kunye nokubhengezwa kokuthintelwa kokusetyenziswa kweeplastiki kwiindawo ezahlukeneyo zelizwe. Ukusetyenziswa kweeplastiki ezisekelwe kwibhayoloji ezinobuhlobo nokusingqongileyo kuya kulawulwa ngakumbi kwaye kuxhaphake ngakumbi.
Isatifikethi samazwe ngamazwe seemveliso ezisekelwe kwibhayoloji
Iiplastiki ezisekelwe kwi-bio luhlobo olunye lweemveliso ezisekelwe kwi-bio, ngoko ke iilebheli zesatifikethi ezisetyenziswa kwiimveliso ezisekelwe kwi-bio zikwasebenza nakwiiplastiki ezisekelwe kwi-bio.
Ileyibhile ye-USDA Bio-Priority ye-USDA, UL 9798 Ukuqinisekiswa koMxholo osekelwe kwiBio, OK Biobased yeBelgian TÜV AUSTRIA Group, eJamani DIN-Geprüft Biobased kunye neBrazil Braskem Company's I'm Green, ezi leyibhile zine zivavanywa umxholo osekelwe kwi-bio. Kwikhonkco lokuqala, kucacisiwe ukuba indlela ye-carbon 14 isetyenziselwa ukufumanisa umxholo osekelwe kwi-bio.
Ileyibhile ye-USDA Bio-Priority kunye ne-UL 9798 Bio-based Content Verification Mark ziya kubonisa ngokuthe ngqo ipesenti yomxholo osekelwe kwi-bio kwileyibhile; ngelixa iileyibhile ze-OK Bio-based kunye ne-DIN-Geprüft Bio-based zibonisa uluhlu oluqikelelweyo lomxholo osekelwe kwi-bio kwimveliso; iileyibhile ze-I' m Green zisetyenziswa ngabathengi beBraskem Corporation kuphela.
Xa kuthelekiswa neeplastiki zemveli, iiplastiki ezisekelwe kwibhayoloji ziqwalasela kuphela inxalenye yezinto eziluhlaza, kwaye zikhetha izinto ezithathwe kwibhayoloji ukuze zithathe indawo yezixhobo ze-petrochemical ezijongene nokunqongophala. Ukuba usafuna ukuhlangabezana neemfuno zomyalelo wokuthintela iplastiki wangoku, kufuneka uqale kwisakhiwo sezinto ukuze uhlangabezane neemeko ezinokubola.
