Ngaba i-biodegrades?
•I-Polylactic Acid, ekwabizwa ngokuba yi-PLA, ibe yiminyaka emininzi. Nangona kunjalo, abavelisi abaphambili beplanti bangenise kuphela intengiso emva kokufumana inkxaso-mali kwiinkampani ezinkulu ezinomdla wokutshintsha iplasitiki ye-syntics. Ke, ngaba i-biodegrades?
•Ngelixa impendulo ayilula, sagqiba kwelokuba sinike inkcazo size sicebise ukufundisisa kwabo banomdla. Iphepha alikho biodegrades, kodwa liyadideka. I-enzymes enokuqhekeza iPLA ayifane ifumaneke kwindalo. IProteinase k yi-enzyme ekhathaza ukonakaliswa kweplani nge-hydrolysis. Abaphandi abanje ngo-Williams ngo-1981 kwaye i-Tsuji naseMiyauchi ngo-2001 yahlola umba wokuba i-PA i-Biodegraded. Iziphumo zabo zixoxwa kwincwadi ye-biomateals Isayensi: Intshayelelo yezonyango kwaye iboniswe kwintlanganiso ye-Euromans yaseYurophu. Ngokwalo mthombo, i-pla ilawulwa ngokuyintloko yi-hydrolysis, ngaphandle kwayo nayiphi na iarhente yebhayoloji. Ngelixa abantu abaninzi banokucinga ukuba i-biodegrades enokuqondeka, kubalulekile ukufezekisa oku.
•Ngapha koko, i-hydrolysis ye-plathiinase k inqabile ukuba ayibalulekanga ngokwaneleyo ukuba ixoxwe ngokubhekele phaya kwi-biomatery. Sinethemba lokuba oku kucacisa imiba ejikeleze i-biodeiance kwaye siya kuqhubeka nemizamo yethu yokubonelela ezona zisombululo zintle zendalo kunye neemfuno zeplastiki ezinokusetyenziswa.
IIsiphelo:
Iplastiki yeplastiki enokusetyenziswa ngokubanzi kwizinto zemihla ngemihla ezinjengeengxowa ezilahlekileyo kunye neekomityi. Nangona kunjalo, inokude ihlazo kuphela kwimimandla yemizi-mveliso okanye indawo yokugaya i-anaerobic, yenza ukonakaliswa kwendalo imeko eqhelekileyo yendalo icele umngeni. Izifundo ziqinisekisile ukuba i-Plarades ihlazo elincinci kwimo yaselwandle.
