Isikhumba esenziwe ngokwenziwa noma esenziwe ngenkohliso asinalo unya futhi sinokuziphatha okuhle. Isikhumba esenziwe ngokwenziwa siziphatha kangcono ngokwezinga lokusimama kunesikhumba esivela ezilwaneni, kodwa sisakhiwe ngepulasitiki futhi sisalimaza.
Kunezinhlobo ezintathu zesikhumba esenziwe ngokwenziwa noma esenziwe ngenkohliso:
Isikhumba se-PU (i-polyurethane),
I-PVC (i-polyvinyl chloride)
okusekelwe ku-bio.
Inani lemakethe lesikhumba esenziwe ngokwenziwa lalingama-USD ayizigidigidi ezingama-30 ngo-2020 futhi kulindeleke ukuthi lifinyelele kuma-USD ayizigidigidi ezingama-40 ngo-2027. I-PU ibambe isabelo esingaphezu kwama-55% ngo-2019. Ukukhula kwayo okuthembisayo kungenxa yekhwalithi yomkhiqizo: ayinamanzi, ithambile kune-PVC, futhi ilula kunesikhumba sangempela. Ingahlanzwa futhi ingathinteki elangeni. I-PU iyindlela engcono kune-PVC ngoba ayikhiphi ama-dioxin kuyilapho i-bio-based iyisimeme kunazo zonke.
Isikhumba esisekelwe ku-bio senziwe nge-polyester polyol futhi sinokuqukethwe okuvuselelekayo okungu-70% kuya ku-75%. Sinobuso obuthambile futhi sinamandla okumelana nokuklwebheka kangcono kune-PU ne-PVC. Singalindela ukukhula okukhulu kwemikhiqizo yesikhumba esisekelwe ku-Bio esikhathini sokubikezela.
Izinkampani eziningi emhlabeni wonke zigxila ekuthuthukisweni kwemikhiqizo emisha equkethe ipulasitiki encane nezitshalo eziningi.
Isikhumba esisekelwe ku-bio senziwe ngengxube ye-polyurethane nezitshalo (izitshalo eziphilayo) futhi asithathi hlangothi ku-carbon. Wake wezwa ngesikhumba se-cactus noma sikaphayinaphu? Singokwemvelo futhi siyabola kancane, futhi sibukeka simangalisa! Abanye abakhiqizi bazama ukugwema ipulasitiki futhi basebenzise i-viscose eyenziwe ngegxolo le-eucalyptus. Siba ngcono kuphela. Ezinye izinkampani zakha i-collagen noma isikhumba esikhuliswe elabhorethri esenziwe ngezimpande zamakhowe. Lezi zimpande zikhula emfucumfucwini eminingi yemvelo futhi inqubo iguqula imfucuza ibe imikhiqizo efana nesikhumba. Enye inkampani isitshela ukuthi ikusasa lenziwe ngezitshalo, hhayi amapulasitiki, futhi ithembisa ukudala imikhiqizo eshintshashintshayo.
Ake sisize ukuchuma kwemakethe yesikhumba esekelwe ku-bio!
