Isikhumba esenziwe ngokwenziwa okanye esenziwe ngenkohliso asinankohlakalo kwaye silungile kwisiseko saso. Isikhumba esenziwe ngokwenziwa siziphatha ngcono ngokwemeko yaso yokuhlala kunesikhumba esivela kwizilwanyana, kodwa sisakhiwe ngeplastiki kwaye sisenobungozi.
Kukho iintlobo ezintathu zesikhumba esenziwe ngokwenziwa okanye esenziwe ngenkohliso:
Isikhumba se-PU (i-polyurethane),
I-PVC (i-polyvinyl chloride)
isekelwe kwi-bio.
Ixabiso lemarike lesikhumba esenziweyo laliyi-30 yeebhiliyoni zeedola ngo-2020 kwaye kulindeleke ukuba lifikelele kwi-40 yeebhiliyoni ngo-2027. I-PU yayinesabelo esingaphezulu kwe-55% ngo-2019. Ukukhula kwayo okuthembisayo kungenxa yomgangatho wemveliso: ayinamanzi, ithambile kune-PVC, kwaye ikhaphukhaphu kunesikhumba sokwenyani. Ingacocwa kwaye ayichaphazeleki elangeni. I-PU yindlela engcono kune-PVC kuba ayikhuphi ii-dioxin ngelixa i-bio-based iyeyona izinzileyo kuzo zonke.
Isikhumba esisekelwe kwi-bio senziwe nge-polyester polyol kwaye sinomthamo ohlaziyekayo ongama-70% ukuya kuma-75%. Sinomphezulu othambileyo kwaye sinamandla okumelana nokukrwela angcono kune-PU kunye ne-PVC. Singalindela ukukhula okukhulu kweemveliso zesikhumba esisekelwe kwi-Bio kwixesha eliqikelelweyo.
Iinkampani ezininzi kwihlabathi liphela zigxile kuphuhliso lwemveliso entsha equlethe iplastiki encinci kunye nezityalo ezininzi.
Isikhumba esisekelwe kwi-bio senziwe ngomxube we-polyurethane kunye nezityalo (izityalo zendalo) kwaye asithathi cala kwi-carbon. Ngaba ukhe weva ngesikhumba se-cactus okanye sepayinapile? Singokwemvelo kwaye siyabola kancinci, kwaye sibukeka simangalisa! Abanye abavelisi bazama ukuphepha iplastiki kwaye basebenzise i-viscose eyenziwe ngegxolo le-eucalyptus. Siba ngcono kuphela. Ezinye iinkampani ziphuhlisa i-collagen okanye isikhumba esikhuliswe elebhu esenziwe ngeengcambu zekhowa. Ezi ingcambu zikhula kuninzi lwenkunkuma yendalo kwaye inkqubo iguqula inkunkuma ibe ziimveliso ezifana nesikhumba. Enye inkampani isixelela ukuba ikamva lenziwe ngezityalo, hayi iiplastiki, kwaye ithembisa ukwenza iimveliso ezintsha.
Masincede ekukhuleni kwemarike yesikhumba esekelwe kwibhayoloji!
