Njengoba isidingo semikhiqizo esimeme futhi engahambisani nemvelo siqhubeka sikhula,izinto zokusetshenziswa komjovo ezingaboliziye zavela njengezihamba phambili emkhakheni wokukhiqiza nokuthuthukiswa kwemikhiqizo.Lezi zinto ezintsha zinikeza enye indlela ephoqelelayo kumapulasitiki avamile, inikeza isisombululo esinciphisa umthelela wemvelo ngaphandle kokuyekethisa ukusebenza.Kodwa-ke, ukwehlukahlukana kwezinto ezingavuthiwe zokubumba umjovo ongaboli kungaletha izinselelo kochwepheshe bokuthenga nabaklami bemikhiqizo.Ukuqonda amabanga ahlukene kanye nezici zawo ezihlukile kubalulekile ekwenzeni izinqumo ezinolwazi ezihambisana nezidingo ezithile zohlelo lokusebenza.
Ukungena Emhlabeni Wokubumba Umjovo Ongavuthiwe Amabanga Wempahla
Izinto ezisetshenziswayo zokusetshenziswa ngomjovo ongabolikuhlanganisa uchungechunge olubanzi lwamabanga, ngalinye linezimpawu ezihlukile nezici zokusebenza.Lawa mabanga avame ukuhlukaniswa ngokusekelwe ekwakhekeni kwawo kwamakhemikhali, izinga le-biodegradation, nokufaneleka kwezinhlelo ezithile zokusebenza.Ukuqonda lokhu kwehluka kubalulekile ekukhetheni izinto ezifanele kakhulu zephrojekthi ethile.
- I-Polylactic Acid (PLA):I-PLA ime njengomunye wezinto ezingavuthiwe ezisetshenziswa kakhulu ngomjovo ongaboli.Isuselwe ezinsizeni ezivuselelekayo ezifana nesitashi sombila noma umoba, i-PLA ibonisa ukuqina okungavamile, amandla aphezulu, nokucaca okuhle kakhulu kokubona.Izinga le-biodegradation yayo liyahlukahluka kuye ngokwakhiwa okuqondile, kusukela ezinyangeni ezimbalwa kuya eminyakeni embalwa ngaphansi kwezimo zokuvundisa zezimboni.
- I-Polyhydroxyalkanoates (PHAs):Ama-PHA amelela umndeni wama-polymers angaboli akhiqizwa ama-microorganisms.Lezi zinto ezisetshenziswayo ziziqhayisa ngamazinga akhethekile okuwohloka kwemvelo, abhidlika ngokuphelele phakathi nezinyanga noma ngisho namaviki ngaphansi kwezimo zemvelo.Ama-PHA aphinde abonise amandla aphezulu, ukuguquguquka, kanye nezakhiwo zokuvimbela, okuwenza afanelekele uhla olubanzi lwezinhlelo zokusebenza, okuhlanganisa ukupakisha, izisetshenziswa zezokwelapha, nemikhiqizo yezolimo.
- I-Bioplastics esekelwe isitashi:I-bioplastics esekelwe isitashi itholakala emithonjeni yesitashi evuselelekayo, efana nommbila noma isitashi samazambane.Lezi zinto zinikeza enye indlela engabizi futhi evumelana nemvelo kumapulasitiki endabuko, ebonisa ukubola okuhle kwe-biodegradability kanye ne-compostability.Kodwa-ke, ama-bioplastic asekelwe isitashi angase abe namandla aphansi nokumelana nomswakama uma kuqhathaniswa nezinye izinto ezibolayo.
- I-Bioplastics esekelwe ku-Cellulose:Ama-bioplastic asekelwe ku-cellulose atholakala ku-cellulose, i-polymer yemvelo eningi etholakala ezindongeni zamaseli ezitshalo.Lezi zinto zinikeza amandla akhethekile, ukuqina, kanye nezakhiwo zokuthibela, ezizenza zifanelekele izinhlelo zokusebenza ezifuna ukusebenza okuphezulu.I-bioplastics esekelwe ku-cellulose iphinde ibonise ukubola okuhle kwe-biodegradability, ukuwohloka phakathi nezinyanga noma iminyaka ngaphansi kwezimo zokuvundisa zezimboni.
Ukuchaza Umehluko: Ukuqonda Ukuhlukahluka Kwebanga
Ukwehluka phakathi kwamabanga wezinto ezingavuthiwe zokubumba umjovo ongaboli kubangelwa umehluko ekwakhekeni kwawo kwamakhemikhali, amapharamitha okucubungula, kanye nezithasiselo.Lezi zici zithonya izici zezinto ezibonakalayo, njengamandla emishini, izinga le-biodegradation, kanye nokuhambisana nezinqubo ezikhona zokubumba umjovo.
- Ukwakhiwa Kwekhemikhali:Ukwakheka kwamakhemikhali wezinto ezingavuthiwe zokubumba umjovo ongaboli kunquma izici zayo ezibalulekile, okuhlanganisa amandla, ukuguquguquka, kanye nokubola kwe-biodegradability.Isibonelo, amandla aphezulu kanye nokuqina kwe-PLA kuvela kumaketango ayo amade e-polymer, kuyilapho ukubola kwe-PHAs kubangelwa ukuwohloka kwawo kwe-enzymatic amagciwane.
- Icubungula amapharamitha:Imingcele yokucubungula esetshenziswa ngesikhathi kukhiqizwa izinto ezingavuthiwe zokubumba umjovo ongaboli zingaba nomthelela omkhulu ezimpahleni zazo.Izinto ezifana nezinga lokushisa, ingcindezi yokubumba, nezinga lokupholisa kunomthelela ekucwebezeleni kwezinto, umumo, nezici zangaphezulu.
- Izithasiselo:Ukwengezwa kwezithasiselo ezithile, njengamapulasitiki, iziqinisi, nama-ejenti aqinisayo, kungaqhubeka nokuguqula izakhiwo zezinto ezingavuthiwe zokubumba umjovo ongaboli.Lezi zithasiselo zingathuthukisa ukuguquguquka kwezinto, zithuthukise ukuzinza kwazo ngokumelene nezici zemvelo, noma zikhulise amandla ako okusebenza.
Isiphetho
I-landscape ehlukahlukene yebiodegradable umjovo ukubumba impahla eluhlazaamabanga aveza inqwaba yezinketho zochwepheshe bokuthenga nabaklami bemikhiqizo.Ngokuqonda izici ezihlukile nezici zokusebenza zebanga ngalinye, kungenziwa izinqumo ezinolwazi ezihambisana nezidingo ezithile zohlelo lokusebenza.I-SIKO isalokhu izibophezele ekunikezeni amakhasimende ethu izinto zokusetshenziswa zekhwalithi ephezulu kakhulu ezibolekwa umjovo, kuhlanganiswe nesiqondiso nokusekelwa kochwepheshe, ukuze abanike amandla okuzulazula enkingeni yokukhethwa kwezinto ezibonakalayo nokudala imikhiqizo esimeme ehlangabezana nezidingo zomhlaba wesimanje.
