Ese imyenda idoda ibora

Igitambara kidoda ni iki?

Imyenda idoda ni ubwoko bushya bwibidukikije byangiza ibidukikije. Bitandukanye nimyenda gakondo isaba inzira igoye nko kuzunguruka no kuboha, ni ibikoresho byurusobe rwa fibre byakozwe no kuvanga fibre cyangwa kuzuza hamwe na kole cyangwa fibre yashonze muburyo bwashongeshejwe ukoresheje membrane, mesh, cyangwa uburyo bwo kumva. Imyenda idoda ifite imbaraga nyinshi, guhumeka neza, kwihanganira kwambara, guhinduka neza, kutagira amazi no kutagira amazi, bityo bikaba byarakoreshejwe cyane mubuzima bwa buri munsi.

Ni ubuhe buryo bwo gutesha agaciro imyenda idoda?

Imyenda idoda itandukanye na plastiki ishobora kwangirika kuko igizwe na fibre synthique, fibre fibre fibre, fibre yongeye gukoreshwa, nibindi bikoresho, kandi ntishobora kwangirika cyangwa kubora na mikorobe. Ndetse no mubidukikije, imyenda idoda irafata imyaka mirongo, ndetse nibinyejana, kugirango ibore. Niba umubare munini wimyenda idoda ikajugunywa mubidukikije igihe kirekire, bizatera ingaruka mbi kubidukikije.

Ariko, hariho kandi ibikoresho bimwebimwe bishobora kwangirika bidafite ubudodo biboneka ubungubu, kandi niba umwenda utaboshywe ubora biterwa nibigize. Imyenda idoda ikozwe muri acide polylactique (PLA) nibindi bikoresho bishobora kwangirika birashobora kwangirika, mugihe imyenda idoda idoze ikozwe mubikoresho bya pulasitiki gakondo nka polypropilene (PP) na polyethylene (PE) ntishobora kubora ibinyabuzima.

Ibisobanuro nibyiza bya biodegradable idashobora kuboha

Ibinyabuzima bidashobora kwangirika bivuga imyenda idoda ishobora kubora na mikorobe, inyamaswa n’ibimera, hydrolysis cyangwa fotolisi mu bihe bimwe na bimwe. Ugereranije n’imyenda gakondo ya pulasitike idoda, irashobora kugabanya neza ibidukikije.
Muri sosiyete ya none, kurengera ibidukikije byabaye impungenge ku isi yose, kandi imyenda idashobora kwangirika idashobora kuboherwa cyane kubera ibidukikije.

Ubwoko nibiranga biodegradable imyenda idoda

Ibisanzwe bikoreshwa mubinyabuzima bidashobora kuboha muri iki gihe birimo ubwoko butatu bukurikira:

Ibinyamisogwe bishingiye ku binyabuzima bidashobora kuboha

Ibinyamisogwe bishingiye ku binyabuzima bidashobora kuboha ni imyenda yangiza ibidukikije idahimbwe cyane cyane igizwe na krahisi kandi ikozwe no kongeramo plasitike, ibikoresho byongera imbaraga, ibikoresho byongerera imbaraga, nibindi. Byongeye kandi, ibinyamisogwe bishingiye ku binyabuzima bidashobora kuboha bifite igiciro gito kandi ni imyenda yangiza ibidukikije idoda kandi idakoreshwa neza.

Acide polylactique ishingiye kuri biodegradable idoda

Acide polylactique ishingiye kuri biodegradable idoda idoda ni imyenda yangiza ibidukikije idoda idoda ikozwe ahanini na acide polylactique ikoresheje uburyo bwa chimique polymer. Ugereranije n’imyenda gakondo ya pulasitike idoda, aside polylactique ishingiye kuri biodegradable idashobora kuboha ifite ibinyabuzima byiza kandi bihamye. Byongeye kandi, aside polylactique ishingiye kuri biodegradable idashobora kuboha irashobora kwangiza neza CO2 namazi, ikarekura ingufu nyinshi zubushyuhe, bigatuma iba imyenda myiza yangiza ibidukikije idoda.

Cellulose ishingiye kuri biodegradable idoda

Cellulose ishingiye kuri biodegradable idashobora kuboha ni imyenda yangiza ibidukikije idoda cyane cyane igizwe na selile kandi ikozwe mukongeramo ibikoresho byubaka nibikoresho. Ugereranije n’imyenda gakondo ya pulasitike idoda, selile ishingiye kuri biodegradable idashobora kuboha ifite ibinyabuzima byiza kandi bifite umubiri. Byongeye kandi, selile ishingiye kuri biodegradable idashobora kuboha imyenda nayo ifite guhumeka neza no kwinjiza neza, bigatuma iba nziza cyane kubidukikije bidahwitse.

Umwanzuro

Imyenda idoda ubwayo yangirika gahoro gahoro, ariko hariho nibikoresho biodegradable bitari imyenda idoda iraboneka nonaha. Kubikoresho bitaboshywe bidashobora kwangirika vuba, uburyo bwizewe kandi bwangiza ibidukikije bigomba gukoreshwa kugirango bigabanye ingaruka kubidukikije. Kubikoresho bya biodegradable bidoda imyenda, hagomba kongerwa kuzamurwa no gusunika. Menyesha abantu benshi kumenya ingaruka zimyenda idoda, gufatanya kurengera ibidukikije, no kugera kumajyambere arambye.
