NgokweSitatimende Sesimo Sezulu Somhlaba sika-2019 esikhishwe yiNhlangano Yezizwe Ezihlangene kanye ne-World Meteorological Organization (WMO), unyaka ka-2019 bekungunyaka wesibili oshisa kakhulu emlandweni, futhi iminyaka eyi-10 edlule kube unyaka ofudumele kunawo wonke emlandweni.
Imililo yase-Australia ngo-2019 kanye nobhubhane ngo-2020 kuvuke abantu, futhi ake siqale ukukhombisa.
Sesiqala ukuqaphela ukusabela okulethwa ukufudumala kwembulunga yonke, izinguzunga zeqhwa ezincibilikayo, isomiso nezikhukhula, izinsongo ekusindeni kwezilwane, kanye nomthelela empilweni yabantu...
Ngakho-ke, abathengi abaningi ngokwengeziwe sebeqala ukuhlola indlela yokuphila enekhabhoni ephansi futhi enobungani bemvelo ukuze behlise ijubane lokufudumala komhlaba!Lokho kuwukusebenzisa kakhulu imikhiqizo esekwe ku-bio!
1. Yehlisa ukukhishwa kwe-carbon dioxide futhi unciphise umphumela we-greenhouse
Ukushintsha amakhemikhali e-petrochemicals ngemikhiqizo esekwe ku-bio kunganciphisa ukukhishwa kwe-carbon dioxide.
Ukukhiqizwa kweimikhiqizo esekelwe ku-bioikhipha i-carbon dioxide encane kunemikhiqizo esekelwe ku-petroleum."I-Economic Impact Analysis of the US Bio-based Products Industry (2019)" iveze ukuthi, ngokwemodeli ye-EIO-LCA (Life Cycle Assessment), ngo-2017, e-United States ngo-2017 ngenxa yokukhiqizwa nokusetshenziswa kwe-bio. -imikhiqizo esekwe esikhundleni semikhiqizo esekelwe ku-petroleum, amafutha ezinto ezimbiwa phansi Ukusetshenziswa kwehliswe ngo-60%, noma cishe amathani ayizigidi eziyi-12.7 wegesi elingcolisa umoya elilingana ne-CO2.
Izindlela zokulahla ezilandelayo ngemva kokuphela kwempilo ewusizo yomkhiqizo ngokuvamile ziphumela ekukhishweni kwesikhutha, ikakhulukazi amaphakheji epulasitiki asele.
Lapho amapulasitiki esha futhi ephuka, kuphuma isikhutha.I-carbon dioxide ekhishwa ukusha noma ukubola kwamapulasitiki asekelwe ku-bio ayithathi hlangothi futhi ngeke yandise inani le-carbon dioxide emkhathini;ukushiswa noma ukubola kwemikhiqizo esekelwe ku-petroleum kuzokhipha i-carbon dioxide, okuwukukhipha okuhle futhi kuzokwandisa inani eliphelele le-carbon dioxide emkhathini.
Ngakho-ke ngokusebenzisa imikhiqizo esekelwe ku-bio esikhundleni semikhiqizo esekelwe ku-petroleum, i-carbon dioxide emkhathini iyancishiswa.
2. Sebenzisa izinsiza ezivuselelekayo futhi unciphise ukuncika kuwoyela
Imboni ye-bio-based ikakhulukazi isebenzisa izinto ezivuselelekayo (isib. izitshalo, udoti wemvelo) ukukhiqiza nokufaka esikhundleni semikhiqizo yendabuko kusetshenziswa i-petrochemical extracts.Uma kuqhathaniswa nemikhiqizo esekwe ku-petroleum, izinto zayo ezingavuthiwe zinobungani nemvelo.
Ngokombiko we-Economic Impact Analysis yombiko we-US Bio-Based Products Industry (2019), i-United States yonge imiphongolo kawoyela eyizigidi eziyi-9.4 ngokukhiqizwa kwemikhiqizo esekwe ku-bio.Phakathi kwazo, ukusetshenziswa kwamapulasitiki asekelwe ku-bio kanye ne-bio nokupakishwa kwehle ngemiphongolo kawoyela engaba ngu-85,000-113,000.
I-China inendawo enkulu futhi inothile ngezinsiza zezitshalo.Amandla okuthuthuka embonini esekelwe ku-bio makhulu, kuyilapho imithombo kawoyela yezwe lami imfushane.
Ngo-2017, inani eliphelele likawoyela elikhonjwe ezweni lami lalingamathani ayizigidi eziyizinkulungwane ezingama-3.54 kuphela, kanti ukusetshenziswa kukawoyela ongahluziwe kwezwe lami ngo-2017 bekungamathani ayizigidi ezingama-590.
Ukugqugquzela ukukhiqizwa nokusetshenziswa kwemikhiqizo esekelwe ku-bio kuzonciphisa kakhulu ukuncika kuwoyela futhi kunciphise ukukhishwa kokungcola okunamandla okubangelwa ukusetshenziswa kwamandla ezinto ezimbiwa phansi.
Ukudlondlobala kwemboni esekwe kubhayoloji kungahlangabezana nezidingo zentuthuko yanamuhla yomnotho oluhlaza, ohambisana nemvelo nosimeme.
3. Imikhiqizo esekelwe ku-bio, ethandwa izazi zemvelo
Abantu abaningi ngokwengeziwe baphishekela ukuphila okunekhabhoni ephansi kanye nempilo ehambisana nemvelo, futhi imikhiqizo esekelwe ku-bio esebenzisa izinto ezivuselelekayo iya ngokuya ithandwa phakathi kwabathengi.
* Ucwaningo lwe-Unilever lwango-2017 luveze ukuthi u-33% wabathengi bangakhetha izimpahla ezizuzisa umphakathi noma imvelo.Ucwaningo lubuze abantu abadala abangu-2,000 abavela emazweni amahlanu, futhi abangaphezu kwengxenye eyodwa kwesihlanu (21%) yabaphenduli bathi uma ukupakishwa nokuthengisa komkhiqizo kubonisa ngokucacile isitifiketi sawo sokusimama, njengelebula le-USDA, bazokhetha imikhiqizo enjalo.
*I-Accenture yenza inhlolovo kubathengi abangu-6,000 eNyakatho Melika, eYurophu nase-Asia ngo-Ephreli 2019 ukuze baqonde imikhuba yabo yokuthenga nokusebenzisa imikhiqizo epakishwe ngezinto ezihlukene.Imiphumela ikhombise ukuthi u-72% wabaphendulile uthe bebematasa nokuthenga imikhiqizo evikela imvelo kakhulu kunaseminyakeni emihlanu edlule, kanti u-81% uthe balindele ukuthenga eminye yale mikhiqizo eminyakeni emihlanu ezayo.njengathibiobased isikhumba, 10%-80%, KUZE KUWE.
4. Isitifiketi sokuqukethwe okususelwa ku-Bio
Imboni yomhlaba wonke esekwe ku-bio iye yathuthuka iminyaka engaphezu kweyi-100.Ukuze kuthuthukiswe ukuthuthukiswa okujwayelekile komkhakha we-bio-based, i-ASTM D6866, ISO 16620, EN 16640 namanye amazinga okuhlola ethulwe emhlabeni wonke, asetshenziselwa ngokukhethekile ukutholwa kokuqukethwe okusekelwe ku-bio emikhiqizweni esekelwe ku-bio.
Ukuze usize abathengi bathole imikhiqizo yangempela neyekhwalithi ephezulu esekelwe ku-bio, ngokusekelwe kumazinga okuhlola amathathu angenhla amukelwa emhlabeni wonke, amalebula e-USDA bio-based priority, OK Biobased, DIN CERTCO, ngiluhlaza kanye nesitifiketi sokuqukethwe se-UL bio-based. amalebula ethulwe ngokulandelana.
Ngekusasa
Esimeni sokushoda okwandayo kwemithombo kawoyela emhlabeni wonke kanye nokuqina kokufudumala kwembulunga yonke.Imikhiqizo esekelwe ku-bio isekelwe ekuthuthukisweni nasekusetshenzisweni kwemithombo evuselelekayo, ukuthuthukisa "umnotho oluhlaza" osimeme futhi ovumelana nemvelo, ukunciphisa ukukhishwa kwe-carbon dioxide, ukunciphisa umphumela obamba ukushisa, futhi esikhundleni semithombo ye-petrochemical, isinyathelo ngesinyathelo empilweni yakho yansuku zonke.
Cabanga ngekusasa, isibhakabhaka sisaluhlaza, izinga lokushisa alisanyuki, izikhukhula azisakhukhuli, konke lokhu kuqala ngokusetshenziswa kwemikhiqizo eyenziwe nge-bio!
