Ishishini lemveliso yasekhaya kunye nelomntu siqu lijongana noluhlu lwemiba echaphazela ukhathalelo lomntu kunye nemixube yokucoca indlu.
I-2023 World Surfactant Conference eququzelelwe yi-CESIO, iKomiti yaseYurophu ye-Organic Surfactants kunye ne-Intermediates, yatsala abaphathi be-350 kwiinkampani zokuqulunqa ezifana ne-Procter & Gamble, i-Unilever kunye ne-Henkel.Kwakhona bekukho iinkampani ezimeleyo kuzo zonke iinkalo zekhonkco lokubonelela.
I-CESIO 2023 yenzeka eRoma ukusuka ngomhla wesi-5 ukuya kwi-7 kaJuni.
Usihlalo weNkomfa uTony Gough wase-Innospec wamkele abazimasi;kodwa kwangaxeshanye, wabeka uthotho lwemiba eqinisekileyo ukuba iya kulinganisa kushishino lwe-surfactants kwiiveki, iinyanga kunye neminyaka ezayo.Wabonisa ukuba ubhubhane olutsha lwesithsaba luye lwabonisa ukulinganiselwa kwenkqubo yokunakekelwa kwempilo yehlabathi;ukukhula kwabemi behlabathi kuya kwenza i-UN's -1.5°C ukuzibophelela kwemozulu yehlabathi kube nzima ngakumbi;Imfazwe yaseRashiya eUkraine ichaphazela amaxabiso;ngo-2022, iikhemikhali ze-EU Ukuthengwa kwempahla kwamanye amazwe kwaqala ukudlula ukuthunyelwa ngaphandle.
“IYurophu inexesha elinzima lokukhuphisana ne-United States ne-China,” uvumile uGough.
Ngelo xesha, abalawuli babeka iimfuno ezikhulayo kwishishini lokucoca kunye nabanikezeli bayo, abaye bahamba besuka kwi-fossil feedstocks.
"Sihamba njani kwizithako eziluhlaza?"wabuza abaphulaphuli.
Imibuzo engakumbi kunye neempendulo zaphakanyiswa ngexesha lomcimbi weentsuku ezintathu, kunye namazwi okwamkela avela kuRaffael Tardi we-Italian Association for Fine and Specialty Chemicals AISPEC-Federchimica."Ushishino lweekhemikhali lusembindini we-European Green Deal. Ishishini lethu lichaphazeleka kakhulu ngamanyathelo omthetho, "watshela abantu ababekho."Intsebenziswano kuphela kwendlela yokufumana impumelelo ngaphandle kokuncama umgangatho wobomi."
Wayibiza iRoma ngokuba likomkhulu lenkcubeko kunye nekomkhulu labenzi bomhlaba;ukuqaphela ukuba i-chemistry yayiyintsika yeshishini lase-Italiya.Ngoko ke, i-AISPEC-Federchimica isebenza ekuphuculeni ulwazi lwabafundi be-chemistry ngelixa ichaza ukuba kutheni ukucoca kuyisisombululo esona sisisombululo sokuphucula impilo yabathengi.
Imithetho enzima ibingumxholo wengxoxo ezintlanganisweni nakumagumbi ebhodi kulo lonke umsitho weentsuku ezintathu.Bekungacacanga ukuba amagqabantshintshi afikelele ezindlebeni zabameli be-EU REACH.Kodwa inyani kukuba uGiuseppe Casella, intloko yesebe leKhomishini yaseYurophu kwiREACH, ukhethe ukuthetha ngevidiyo.Ingxoxo kaCasella igxile kuhlaziyo lweREACH, athe wayichaza ineenjongo ezintathu:
Ukuphucula ukukhuselwa kwempilo yabantu kunye nokusingqongileyo ngolwazi olwaneleyo lwekhemikhali kunye nemilinganiselo yokulawula ingozi efanelekileyo;
Ukuphucula ukusebenza kunye nokhuphiswano lwemarike yangaphakathi ngokulungelelanisa imithetho ekhoyo kunye neenkqubo zokwandisa ukusebenza kakuhle;kwayeUkuphucula ukuthotyelwa kweemfuno ze-REACH.
Izilungiso zobhaliso ziquka ulwazi olutsha lwengozi olufunekayo kwidosi yobhaliso, kubandakanywa nolwazi olufunekayo ukuchonga abaphazamisi be-endocrine.Ulwazi oluthe vetshe kunye/okanye olongezelelweyo malunga nokusetyenziswa kweekhemikhali kunye nokuvezwa.Izaziso zePolymer kunye noBhaliso.Ekugqibeleni, izinto ezintsha zokwahlula umxube ziye zavela kwiimvavanyo zokhuseleko lweekhemikhali ezithatha ingqalelo kwimiphumo edibeneyo yeekhemikhali.
Amanye amanyathelo abandakanya ukwenza lula inkqubo yogunyaziso, ukwandisa indlela yokulawula umngcipheko ngokubanzi kwezinye iindidi zeengozi kunye nosetyenziso oluthile olukhethekileyo, nokwazisa ingqiqo yosetyenziso olusisiseko olujolise ekukhawuleziseni ukwenziwa kwezigqibo kwiimeko ezicacileyo.
Olu hlaziyo luza kwazisa nokubanakho kophicotho lwaseYurophu ukuze kuxhaswe abasemagunyeni kunye nokulwa ukuthengiswa kwe-intanethi ngokungekho mthethweni.Uhlaziyo luya kuphucula intsebenziswano nabasemagunyeni kwimpahla ephumayo ukuqinisekisa ukuba ukuthengwa kwempahla kumazwe angaphandle kuthobela iREACH.Okokugqibela, abo baneefayile zabo zobhaliso zingahambelaniyo nokuthobela iinombolo zabo zobhaliso baya kurhoxiswa.
La manyathelo aya kusebenza nini?UCasella uthe isiphakamiso sekomiti siza kwamkelwa kwikota yesine ka-2023 mva nje.Iinkqubo zowiso-mthetho eziqhelekileyo kunye neekomiti ziya kuqhubeka ngo-2024 nango-2025.
“I-REACH yayilucelomngeni ngowama-2001 nowama-2003, kodwa olu hlaziyo lulucelomngeni ngakumbi!”waqaphela u-Alex Föller, umongameli wenkomfa waseTegewa.
Abaninzi banokucinga ukuba abenzi bomthetho be-EU banetyala lokugqithisa nge-REACH, kodwa abadlali abathathu abakhulu kushishino lokucoca lwehlabathi bane-ajenda zabo zozinzo, eziye zaxoxwa nzulu kwiseshoni yokuvula iCongress.UPhil Vinson kaProcter & Gamble waqala intetho yakhe ngokuncoma ihlabathi labantu abasebenzisa i-surfactants.
"Ii-surfactants zicingelwa ukuba zidlale indima ebalulekileyo ekuphuhliseni ubomi ukusuka ekusekweni kwe-RNA," watsho."Oko kusenokungabi yinyani, kodwa yinto efanele ukuqwalaselwa."
Inyaniso kukuba ibhotile ye-litre ye-detergent iqulethe i-250 grams ye-surfactant.Ukuba zonke iimicelles bezibekwe kwitsheyini, bekuya kuba lixesha elaneleyo lokuhamba usiya ngapha nangapha phantsi kokukhanya kwelanga.
"Ndifunda i-surfactants iminyaka eyi-38. Cinga ngendlela abagcina ngayo amandla ngexesha lokucheba," unomdla."I-Vesoles, i-vesicles ecinezelweyo, amawele e-discoidal, i-microemulsions e-bicontinuous. Yiyo ingundoqo yento esiyenzayo. Kuyamangalisa! "
Ngelixa i-chemistry inzima, kunjalo ke imiba ejikeleze izinto eziluhlaza kunye nokwakheka.UVinson uthe i-P&G izimisele kuphuhliso oluzinzileyo, kodwa hayi ngeendleko zokusebenza.Uzinzo kufuneka luzinziswe kweyona nzululwazi ibalaseleyo kunye nokubonelela ngemfanelo, utshilo.Ukujika kubathengi bokugqibela, wabonisa ukuba kwi-survey ye-Procter & Gamble, imiba emithathu kwimiba emihlanu ephezulu abathengi abaxhalabele ngayo yayinxulumene nemiba yokusingqongileyo.
