Lapho ukuvikelwa kwemvelo sekuyinto evunyelwene ngayo emhlabeni wonke, imboni yemfashini nayo iguqulwa buthule. Isikhumba sendabuko sithembele ekuzaleni izilwane nasekushiseni amakhemikhali, ukusetshenziswa kwaso kwamandla aphezulu, indlela yokukhiqiza ukungcola okuphezulu kanye nomqondo wentuthuko eqhubekayo kancane kancane kude. Ukuzalwa kwesikhumba esisekelwe ku-bio, njengokusa okuluhlaza esibhakabhakeni, embonini yemfashini kuvule ubuhle kanye nomthwalo wemfanelo womgwaqo omusha.
Njengoba imvelo ingumthombo, ishintsha ikusasa lesikhumba
Izinto eziyinhloko zesikhumba esisekelwe ku-bio zivela ezitshalweni ezivuselelekayo ezifana nommbila, i-cactus kanye namakhowe. Ngokusebenzisa ubuchwepheshe bokuvutshelwa kwamagciwane noma ubuchwepheshe be-biosynthesis, i-cellulose, amaprotheni nezinye izingxenye zalezi zitshalo ziguqulwa zibe izinto ezintsha ezinesikhumba. Isibonelo, i-polylactic acid (PLA) ekhishwe kusitashi sommbila ingacutshungulwa ibe yisikhumba esithambile nesiphefumulayo, futhi isakhiwo sayo sama-molecule singalingisa ngisho nokuhlelwa kwemicu esikhumbeni, okwenza kube mnene ukuthintwa futhi kumelane nokuklwebheka nokuklebhuka. Le modeli yokukhiqiza evaliwe "kusukela epulazini kuya emfashinini" inciphisa umthelela wekhabhoni ube yi-1/5 yesikhumba sendabuko, okwenza ngempela ukukhiqizwa okuluhlaza okulawulwa umthombo.
Ukuthuthukiswa kwesayensi nobuchwepheshe, isithiyo sokusebenza kahle
kuye kwabuzwa: izinto zokuvikela imvelo zingacabangela ukusebenza? Isikhumba esisekelwe ku-bio esinesayensi nobuchwepheshe obuqinile ukuphendula lo mbuzo. Ngobuchwepheshe be-nano-coating, ukungangeni kwamanzi kwaso kufinyelela indinganiso ye-ISO 811; ukusetshenziswa kobuchwepheshe bokushiswa kwemifino kanye nokucubungula ama-enzyme e-biological, akugcini nje ngokunikeza impahla ukuthungwa kwemvelo nokukhazimula, kodwa futhi kwenza kube lula ukuphefumula ngaphezu kwesikhumba esivamile se-PU izikhathi ezingaphezu kwezingu-3. Emkhakheni wengaphakathi lezimoto, umkhiqizo wamazwe ngamazwe usebenzise isikhumba esisekelwe ku-bio ngezinga elikhulu, futhi sisalokhu sinjalo ngemva kokuhlolwa kokuhuzuka izikhathi ezingu-200,000; emakethe yezikhwama zemfashini, abaklami basebenzisa i-plasticity yaso ukudala ukuthungwa okunezinhlangothi ezintathu, ukuze ingxenye ngayinye yomsebenzi ibe umsebenzi wobuciko ohambayo.
Ulimi lwemfashini, ukuhumusha ubuhle bemvelo
Ubuhle besikhumba esisekelwe ku-bio budlula ilebula lemvelo. Buyakha kabusha ubuhle bemfashini “ngobuhle baso obunamaphutha” obuhlukile – umehluko wemibala ongabonakali ngokwemvelo kanye nokuthungwa kwezinto zokusetshenziswa kwenza umkhiqizo ngamunye ube uphawu lwemvelo olungenakuphindwa. Isikhwama se-mushroom mycelium esasungulwa ngumkhiqizo wobukhazikhazi wase-Italy sigcina imithambo yemvelo yokukhula kwe-mycelium ebusweni baso; ingubo eyenziwe ngesikhumba se-bamboo fibre esidaywe yitiye ngumklami waseShayina ikhombisa umbala we-amber ngaphansi kwelanga. Le misebenzi ayiseyona imikhiqizo yezimboni ebandayo, kodwa imisebenzi yobuciko be-eco ethwala isikhathi, izinga lokushisa kanye nezindaba zokuphila.
Ukugijima ngezindlela ezimbili, ukwakha i-ecology eluhlaza
Ukukhetha isikhumba esisekelwe ku-bio akuyona nje indlela yomthengi yokuziphatha, kodwa futhi kuyisiqalo sokuhlanganyela emikhubeni yokuvikela imvelo. Imitha ngayinye yesikwele eyodwa yesikhumba esisekelwe ku-bio ilingana nokunciphisa amakhilogremu ama-3 okukhishwa kwe-carbon dioxide nokusindisa amalitha angama-200 amanzi. Lapho abathengi begqoka izingubo zesikhumba esisekelwe ku-bio behamba emgwaqweni, ababonisi nje isitayela sabo somuntu siqu, kodwa futhi baba yisimemezelo esihambayo sokuvikelwa kwemvelo. Njengamanje, kunezinhlobo ezingaphezu kuka-200 emhlabeni jikelele, kusukela ekutshalweni kwezimali kukaHermes ocwaningweni lwesikhumba samakhowe kanye nentuthuko, kuya ochungechungeni lokuvikelwa kwezemvelo olusekelwe ku-bio oluqalwe yi-ZARA, uchungechunge lwezimboni oluphezulu noluphansi lwakha umjikelezo ovaliwe ophelele we-"R & D - ukukhiqizwa - ukuvuselelwa kabusha".
Kulokuphishekela inkathi yokugcina, isikhumba esisekelwe ku-bio esinobuchwepheshe obusha obufakazela: ukuvikelwa kwemvelo akuyona indlela yokuvumelana nemfashini, kodwa ukuvuka kobuhle okuthuthukisiwe. Lapho siguqula iqabunga lommbila libe iphethini elithambile esikhwameni, noma i-algae extract ibe yinto yokuphefumula yezicathulo, sisebenzisa ubuchwepheshe besimanje ukuvuselela ukuhlakanipha kwasempumalanga "kobuTao nemvelo". Ukukhetha isikhumba esisekelwe ku-bio akuyona nje ukuzibophezela okumnene emhlabeni, kodwa futhi kuyivoti yemfashini yesikhathi esizayo - ukuze yonke isentimitha yesikhumba ethintwe ubuhle bezindleko zemvelo ingasathwalwa.
