Munhanho yakakosha yekuenderera mberi, masayendisiti akagadzira nzira yekugadzira rabha inogona kushandura indasitiri.Iyi nzira yekuvandudza inovimbisa kuderedza kukanganiswa kwezvakatipoteredza kwekugadzirwa kwerabha uku ichichengetedza zvimiro zvayo zvakakosha zvekushandisa kwakasiyana.
Rubber chinhu chakakosha chinoshandiswa mumaindasitiri mazhinji, anosanganisira emotokari, hutano, uye zvinhu zvevatengi.Sechinyakare, rabha inotorwa kubva kune yakasikwa latex yakatorwa kubva mumiti yerabha kana kugadzirwa kubva mupetroleum-based chemicals.Nzira mbiri idzi dzinounza matambudziko ezvakatipoteredza: yekutanga nekuda kwekuparadzwa kwemasango uye kuparadzwa kwenzvimbo, uye yekupedzisira nekuda kwekuvimba nemafuta ezvicherwa uye kuburitswa kwakabatana.
Nzira itsva iyi, yakagadziridzwa nechikwata chevaongorori veGreen Materials Institute, inoshandisa nzira yebiotechnological kugadzira rabha kubva kune zvinogonekazve.Nehuinjiniya ma microorganisms kushandura shuga-based sugar kuita polyisoprene, chikamu chekutanga cherabha yechisikigo, timu yakavhura musuwo wekuita kwakasimba kwekugadzira.
Dr. Emma Clark, muongorori anotungamirira, akatsanangura, kuti: “Chinangwa chedu chakanga chiri chokuwana nzira yokugadzira rabha isingatsamiri pamiti yerabha yechinyakare kana kuti petroleum.Nekushandisa simba rebiotechnology, takagadzira nzira inogona kukwidziridzwa uye kubatanidzwa mune iripo kugadzira masisitimu.
Iyo biotechnological process haingodzikisi kudiwa kwekutema masango chete asi zvakare kuderedza kuburitsa gasi regreenhouse rine chekuita nekugadzirwa kwerabha yechinyakare.Zvakare, iyo inodzokororwa hunhu hwechirimwa-yakavakirwa feedstock inova nechokwadi chekugara kwakasimba cheni.
Iyo rubha nyowani yakamboyedzwa zvakanyanya kuti ive nechokwadi chekuti inosangana neindasitiri zviyero zvekusimba, elasticity, uye kusimba.Mhedzisiro yekutanga yave ichivimbisa, zvichiratidza kuti rabha rinogara iri rinoshanda zvakaenzana neayo echinyakare.
Vanamazvikokota veindasitiri vakarumbidza hutsva uhu sechinhu chinochinja."Kubudirira uku kunogona kuderedza zvakanyanya nharaunda yeindasitiri yerabha," akadaro John Mitchell, muongorori weEcoMaterials."Inopindirana zvakakwana nekukura kuri kudiwa kwezvinhu zvinogoneka muzvikamu zvese."
Sezvo nyika iri kunetsekana nekushanduka kwemamiriro ekunze uye kupera kwezviwanikwa, hunyanzvi hwakadai hwakakosha kune ramangwana rakagadzikana.Green Materials Institute inoronga kushanda pamwe nevagadziri vakuru verabha kuti vaunze tekinoroji nyowani iyi pamusika mukati memakore mashoma anotevera.
Kubudirira uku kunoratidza nguva yakakosha mukutsvaga kwezvinhu zvinoenderera mberi, zvichipa tariro yekuti maindasitiri anogona kushandura kune mamwe maitiro ane hushamwari kwezvakatipoteredza pasina kupira mhando kana kuita.
