1. I-China Yethula Imithetho Emisha Yokunciphisa Ukukhishwa Kwe-VOC, Okuholele Ekwehleni Okuphawulekayo Kwezimbozo Ezisekelwe Ku-Solvent kanye Nokusetshenziswa Kweyinki
NgoFebhuwari 2025, uMnyango Wezemvelo Nezemvelo waseShayina wakhipha Uhlelo Oluphelele Lokuphathwa Kwama-Volatile Organic Compounds (ama-VOC) Ezimbonini Ezibalulekile. Le nqubomgomo iyalela ukuthi, ekupheleni kuka-2025, isilinganiso sokusetshenziswa kwezimbozo zezimboni ezisekelwe ku-solvent kumele sehliswe ngamaphesenti angu-20 uma kuqhathaniswa namazinga ka-2020, uyinki osekelwe ku-solvent ngamaphesenti ayi-10, kanye nezinamathiselo ezisekelwe ku-solvent ngo-20%. Ngaphansi kwalokhu kucindezelwa okuqhutshwa yinqubomgomo, isidingo sezincibilikisi eziphansi ze-VOC kanye nezinye izindlela ezisekelwe emanzini sikhuphuke kakhulu. Engxenyeni yokuqala ka-2025, isabelo semakethe sezincibilikisi ezinobungani nemvelo sesivele sifinyelele ku-35%, okubonisa ukusheshisa okucacile ekuguqukeleni kwemboni kuya emikhiqizweni nasemikhuba eluhlaza, eqhubekayo.
2. Imakethe Yezinyibilikisi Yomhlaba Wonke Idlula AmaRandi Angamabhiliyoni angu-85, i-Asia-Pacific Inikela Ngama-65% Okukhula Okukhulayo
Ngo-2025, imakethe yomhlaba wonke yamakhemikhali yafinyelela inani lamaRandi ayizigidigidi ezingama-85, ikhula ngesilinganiso sonyaka esingu-3.3%. Isifunda sase-Asia-Pacific sivele njengenjini eyinhloko yalokhu kukhula, sinikela ngo-65% wokusetshenziswa okwandisiwe. Okuphawulekayo ukuthi imakethe yaseShayina inikeze ukusebenza okunamandla kakhulu, yafinyelela esikalini esingaba yizigidigidi ezingama-285 zamaRandi.
Lokhu kwanda kubangelwa kakhulu amandla amabili okuthuthukiswa kwezimboni kanye nemithethonqubo eqinile yezemvelo. Lezi zinto ezibangela lokhu zisheshisa ushintsho oluyisisekelo ekubunjweni kwezinyibilikisi. Isabelo semakethe esihlanganisiwe sezinyibilikisi ezisekelwe emanzini kanye nezisekelwe ku-bio, esasimi ku-28% ngo-2024, kulindeleke ukuthi sikhuphuke kakhulu sifinyelele ku-41% ngo-2030. Ngesikhathi esifanayo, ukusetshenziswa kwezinyibilikisi zendabuko ze-halogen kuncipha njalo, okubonisa ukuqhubekela phambili kwemboni ezindleleni eziqhubekayo ezisimeme. Lo mkhuba ugcizelela ukuguquka komhlaba wonke kwezamakhemikhali aluhlaza ngenxa yezindawo ezishintshashintshayo zokulawula kanye nesidingo sabathengi semikhiqizo enesibopho semvelo.
3. I-US EPA Ikhipha Imithetho Emisha Yezinyibilikisi, Iqeda Izinyibilikisi Zendabuko Ezifana Ne-Tetrachloroethylene
Ngo-Okthoba 2025, i-US Environmental Protection Agency (EPA) yethule isethi eqinile yemithethonqubo eqondiswe ezincibilikisini ezithile zezimboni. Isici esiyinhloko sale mithetho ukususwa okuhleliwe kwe-tetrachloroethylene (PCE noma i-PERC). Ukusetshenziswa kwe-PCE kwezentengiselwano kanye nezicelo zabathengi kuzovinjelwa ngokuphelele kusukela ngoJuni 2027. Ngaphezu kwalokho, ukusetshenziswa kwayo emkhakheni wokuhlanza okomile kuhlelelwe ukuvinjelwa ngokuphelele ekupheleni kuka-2034.
Le mithethonqubo iphinde ibeke imikhawulo eqinile ezimweni zokusetshenziswa kwezinye izinyibilikisi ezine-chlorine. Lesi senzo esibanzi sokulawula senzelwe ukuvikela impilo yomphakathi kanye nemvelo ngokunciphisa ukuchayeka kula makhemikhali ayingozi. Kulindeleke ukuthi sikhuthaze ushintsho olusheshayo emakethe, sisunduze izimboni ezithembele kula makhemikhali ukuze zisheshise ukwamukelwa kwazo kwezinye izindlela eziphephile nezinobungani nemvelo. Lesi sinyathelo sibonisa isinyathelo esiwujuqu sabalawuli base-US ekuqondiseni imikhakha yamakhemikhali kanye nokukhiqiza emikhubeni esimeme.
