Ngokusho kweSitatimende sika-2019 mayelana nesimo sezulu somhlaba wonke esakhishwa yiZizwe Ezihlangene kanye ne-World Meteorological Organisation (WMO), unyaka ka-2019 wawungowesibili ofudumele kakhulu emlandweni, futhi iminyaka eyi-10 edlule ibe ngofudumele kakhulu emlandweni.
Imililo yase-Australia ngo-2019 kanye nobhubhane ngo-2020 kuvuse abantu, futhi ake siqale ukucabanga.
Sesiqala ukuqaphela ukusabela kochungechunge okubangelwa ukufudumala komhlaba, ukuncibilika kweqhwa, isomiso kanye nezikhukhula, izinsongo zokusinda kwezilwane, kanye nemiphumela yempilo yabantu…
Ngakho-ke, abathengi abaningi baqala ukuhlola indlela yokuphila engenawo umoya ongcolile futhi enobungani nemvelo ukuze banciphise ijubane lokufudumala komhlaba! Lokho kusho ukusetshenziswa okwengeziwe kwemikhiqizo esuselwe ku-bio!
1. Nciphisa ukukhishwa kwe-carbon dioxide futhi unciphise umphumela wokushisa komhlaba
Ukufaka esikhundleni samakhemikhali e-petrochemicals endabuko ngemikhiqizo esuselwe ku-bio kunganciphisa ukukhishwa kwe-carbon dioxide.
Ukukhiqizwa kweimikhiqizo esuselwe ku-bioikhipha ikhabhoni dioksijini encane kunemikhiqizo esekelwe kuphethiloli. “Ukuhlaziywa Komthelela Wezomnotho we-US Bio-based Products Industry (2019)” kuveze ukuthi, ngokusho kwemodeli ye-EIO-LCA (Life Cycle Assessment), ngo-2017, i-United States ngo-2017 ngenxa yokukhiqizwa nokusetshenziswa kwemikhiqizo esekelwe kuphethiloli ukuze ithathe indawo yemikhiqizo esekelwe kuphethiloli, amafutha asetshenziswayo ancishisiwe ngo-60%, noma amathani ayizigidi ezingu-12.7 okukhishwa kwegesi ebamba ukushisa okulingana ne-CO2.
Izindlela zokulahla umkhiqizo ngemva kokuphela kwesikhathi sokusebenza kwawo zivame ukuholela ekukhishweni kwe-carbon dioxide, ikakhulukazi ukupakishwa kwepulasitiki okusele.
Uma amapulasitiki esha futhi ephuka, i-carbon dioxide iyakhishwa. I-carbon dioxide ekhishwa ukusha noma ukubola kwamapulasitiki asekelwe ku-bio ayithathi hlangothi kwe-carbon futhi ngeke inyuse inani le-carbon dioxide emoyeni; ukusha noma ukubola kwemikhiqizo esekelwe ku-petroleum kuzokhipha i-carbon dioxide, okuyi-positive emission futhi kuzokhulisa inani eliphelele le-carbon dioxide emoyeni.
Ngakho-ke ngokusebenzisa imikhiqizo esekelwe ku-bio esikhundleni semikhiqizo esekelwe ku-petroleum, i-carbon dioxide emkhathini iyancishiswa.
2. Sebenzisa izinsiza ezivuselelekayo futhi unciphise ukuncika ku-oyela
Imboni esekelwe ezintweni eziphilayo isebenzisa kakhulu izinto ezivuselelekayo (isib. izitshalo, imfucuza yezinto eziphilayo) ukukhiqiza nokufaka esikhundleni imikhiqizo yendabuko kusetshenziswa izithasiselo ze-petrochemical. Uma kuqhathaniswa nemikhiqizo esekelwe kuphethiloli, izinto zayo zokusetshenziswa zinobungani kakhulu nemvelo.
Ngokusho kombiko we-Economic Impact Analysis of the US Bio-Based Products Industry (2019), i-United States yonge amabhareli kawoyela ayizigidi ezingu-9.4 ngokukhiqizwa kwemikhiqizo esuselwe ku-bio. Phakathi kwawo, ukusetshenziswa kwepulasitiki esuselwe ku-bio kanye ne-bio kanye nokupakishwa kwehle ngamabhareli kawoyela angaba ngu-85,000-113,000.
IShayina inendawo enkulu futhi icebile ngemithombo yezitshalo. Amandla okuthuthukiswa kwemboni esekelwe ezintweni eziphilayo makhulu, kuyilapho imithombo kawoyela yezwe lami imfushane kakhulu.
Ngo-2017, inani eliphelele lamafutha atholakale ezweni lami lalingamathani ayizigidigidi ezingu-3.54 kuphela, kanti ukusetshenziswa kukawoyela ongahluziwe ezweni lami ngo-2017 kwakungamathani ayizigidi ezingu-590.
Ukukhuthaza ukukhiqizwa nokusetshenziswa kwemikhiqizo esuselwe ezintweni eziphilayo kuzonciphisa kakhulu ukuncika kumafutha futhi kunciphise ukukhishwa kokungcola okukhulu okubangelwa ukusetshenziswa kwamandla angaphansi komhlaba.
Ukukhula kwemboni esekelwe ezintweni eziphilayo kungahlangabezana nezidingo zentuthuko yanamuhla yomnotho oluhlaza, onobungani nemvelo futhi ozinzile.
3. Imikhiqizo esekelwe ku-bio, ethandwa kakhulu ngabashisekeli bemvelo
Abantu abaningi baphishekela impilo engenakhabhoni eningi futhi enobungani nemvelo, futhi imikhiqizo esekelwe ezintweni eziphilayo esebenzisa izinto ezivuselelekayo iya ngokuya ithandwa kakhulu ngabathengi.
* Ucwaningo lwe-Unilever lwango-2017 lubonise ukuthi abathengi abangu-33% bangakhetha izimpahla ezizuzisa umphakathi noma ezemvelo. Ucwaningo lubuze abantu abadala abangu-2,000 abavela emazweni amahlanu, kanti abangaphezu kwengxenye eyodwa kwezinhlanu (21%) yabaphenduli bathi uma ukupakishwa nokumaketha komkhiqizo kukhombisa ngokucacile isitifiketi sawo sokusimama, njengelebula le-USDA, bazokhetha ngenkuthalo imikhiqizo enjalo.
*I-Accenture ihlole abathengi abangu-6,000 eNyakatho Melika, eYurophu nase-Asia ngo-Ephreli 2019 ukuze iqonde imikhuba yabo yokuthenga nokusebenzisa imikhiqizo ehlanganiswe ngezinto ezahlukene. Imiphumela ibonise ukuthi ama-72% abaphendulile bathi bathenga ngenkuthalo imikhiqizo enobungani nemvelo kakhulu kunaseminyakeni emihlanu edlule, kanti ama-81% athi alindele ukuthenga eminye yale mikhiqizo eminyakeni emihlanu ezayo. Njengoba sesibonile,isikhumba esisekelwe kubhayoloji, 10%-80%, KUYA KUWE.
4. Isitifiketi sokuqukethwe okusekelwe ku-bio
Imboni yomhlaba wonke esekelwe ku-bio isithuthuke iminyaka engaphezu kweyikhulu. Ukuze kukhuthazwe intuthuko evamile yemboni esekelwe ku-bio, i-ASTM D6866, i-ISO 16620, i-EN 16640 kanye nezinye izindinganiso zokuhlola seziqalisiwe emhlabeni jikelele, ezisetshenziswa ngokukhethekile ukuthola okuqukethwe okusekelwe ku-bio emikhiqizweni esekelwe ku-bio.
Ukuze kusizwe abathengi ukuthola imikhiqizo yangempela nesezingeni eliphezulu esekelwe ku-bio, ngokusekelwe ezindinganisweni ezintathu zokuhlola ezamukelwe emhlabeni wonke ezingenhla, amalebula okubaluleka asekelwe ku-bio e-USDA, i-OK Biobased, i-DIN CERTCO, i-I'm green kanye namalebula okuqinisekisa okuqukethwe okusekelwe ku-bio e-UL aqaliswe ngokulandelana.
Esikhathini esizayo
Ngenxa yokuntuleka okwandayo kwezinsizakusebenza zikawoyela emhlabeni kanye nokwanda kokufudumala komhlaba. Imikhiqizo esuselwe ku-bio isekelwe ekuthuthukisweni nasekusetshenzisweni kwezinsizakusebenza ezivuselelekayo, ithuthukisa "umnotho oluhlaza" osimeme futhi onobungani nemvelo, inciphisa ukukhishwa kwe-carbon dioxide, inciphise umphumela wokushisa komhlaba, futhi ithathe indawo yezinsizakusebenza zikaphethroli, kancane kancane empilweni yakho yansuku zonke.
Cabanga ngekusasa, isibhakabhaka sisaluhlaza okwesibhakabhaka, izinga lokushisa alisakhuphuki, izikhukhula azisakhuphuki, konke lokhu kuqala ngokusetshenziswa kwemikhiqizo esuselwe ku-bio!
Isikhathi sokuthunyelwe: Feb-19-2022
