Khetha iiTawuli zePhepha eziPhilileyo ezingenazo izongezo zeKhemikhali

Kubomi bethu bemihla ngemihla, iphepha lethishu liyimveliso eyimfuneko, edla ngokusetyenziswa ngokungakhathali ngaphandle kokucinga kakhulu. Nangona kunjalo, ukukhetha iitawuli zephepha kunokuchaphazela kakhulu impilo yethu kunye nokusingqongileyo. Nangona ukukhetha iitawuli zephepha ezingabizi kakhulu kunokubonakala ngathi sisisombululo esingabizi kakhulu, iingozi zempilo ezinxulumene nazo akufuneki zithathwe lula.
Iingxelo zamva nje, kuquka nenye evela kwiSayensi neTekhnoloji yemihla ngemihla ngo-2023, zibonise iziphumo ezoyikisayo malunga nezinto ezinobuthi ezikwiphepha langasese kwihlabathi liphela. Iikhemikhali ezifana nezinto ze-per- kunye ne-polyfluoroalkyl (PFAS) ziye zanxulunyaniswa nemiba eyahlukeneyo yezempilo, kubandakanya umngcipheko okhulayo womhlaza ofana nomhlaza wamaphaphu nowamathumbu, kunye nokwehla okukhulu kokuzala kwabasetyhini ngama-40%. Ezi ziphumo zigxininisa ukubaluleka kokujonga izithako kunye nezinto ezisetyenziswa kwiimveliso zephepha.
Xa bekhetha iitawuli zephepha, abathengi kufuneka baqwalasele izinto ezisetyenzisiweyo ezibandakanyekayo. Iindlela eziqhelekileyo ziquka i-virgin wood pulp, i-virgin pulp, kunye ne-bamboo pulp. I-virgin wood pulp, ephuma ngqo kwimithi, ineefayibha ezinde kunye namandla aphezulu, kodwa imveliso yayo idla ngokukhokelela ekugawulweni kwamahlathi, okonakalisa ibhalansi yendalo. I-virgin pulp, ngelixa icutshungulwa kwaye iphathwa, idla ngokubandakanya iikhemikhali zokufiphaza ezinokungcolisa imithombo yamanzi ukuba ayilawulwa kakuhle.
Ngokwahlukileyo koko, i-bamboo pulp ivela njengenye indlela engcono. I-bamboo ikhula ngokukhawuleza kwaye ivuthwa ngokukhawuleza, nto leyo eyenza ukuba ibe sisixhobo esizinzileyo esinciphisa ukuxhomekeka emahlathini. Ngokukhetha izicubu ze-bamboo, abathengi abakhethi nje kuphela imveliso enempilo engenazo izongezo eziyingozi kodwa banegalelo ekugcinweni kwendalo.
Ukuqukumbela, xa uthenga iitawuli zephepha, kubalulekile ukujonga ngaphaya kwexabiso. Ukukhetha izicubu zebhambo akukhuthazi nje kuphela impilo yomntu ngokuphepha iikhemikhali ezinobungozi kodwa kuxhasa nekamva elizinzileyo nelinobuhlobo nokusingqongileyo. Tshintshela kwiitawuli zephepha ezinempilo namhlanje kwaye ukhusele impilo-ntle yakho kunye neplanethi.
