Amakuru - Gushyira ahagaragara Ifu y'ibigori muri Bioplastics: Uruhare rwabyo ni uruhe?

Mu buzima bwacu bwa buri munsi, ibikoresho bya pulasitiki birakwirakwira hose. Ariko, ibibazo bikomeza kwiyongera by’ibidukikije biterwa na pulasitiki gakondo byatumye abantu bashaka ubundi buryo burambye. Aha niho ibinyabuzima bya pulasitiki bishyirwa mu bikorwa. Muri byo, ibinyampeke by’ibigori bigira uruhare runini nk’igice gisanzwe muri pulasitiki. None se, uruhare rwaibinyampeke by'ingano mu bimera bya pulasitiki?

1. Bioplastics ni iki?
Bioplastic ni pulasitiki ikozwe mu bintu bishobora kongera gukoreshwa nk'ibimera cyangwa mikorobe. Bitandukanye na pulasitiki gakondo, bioplastic ikorwa mu bintu bishobora kongera gukoreshwa, bityo bigatuma ingaruka ku bidukikije zigira ingaruka nke. Ifu y'ibigori, muri byo, ikoreshwa nk'igice cy'ingenzi muri bioplastic.

2. Uruhare rw'ibinyampeke by'ibigori mu binyabuzima

Ifu y'ibigori by'ingenzi bikora imirimo itatu y'ingenzi:
Igihingwa cy'ibigori gikora uruhare mu kongera, gutuza no kunoza imiterere y'ibikomoka kuri bioplastike. Ni polymer ishobora guhuzwa n'izindi polymer zishobora kubora cyangwa plasticizers kugira ngo habeho inyubako zihamye. Mu kongeramo inyongeramusaruro zikwiye ku gihingwa cy'ibigori, ubukana, ubwiyongere n'umuvuduko wo kwangirika kwa bioplastike bishobora guhindurwa, bigatuma bikwiranye n'uburyo butandukanye bwo gukoreshwa.
Kongera imbaraga za mekanike: Gushyiramo ifu y'ibigori bishobora kongera ubukana n'imbaraga zo gukurura za bioplastics, bigatuma ziramba.

Kunoza imikorere yo gutunganya: Kuba hari ibinyampeke by'ibigori bituma bioplastics zirushaho kumera neza mu gihe cyo gutunganya, bityo bigatuma habaho ibintu bitandukanye bifite imiterere itandukanye.

Byongeye kandi, ibinyampeke by'ibigori bifite ubushobozi bwo kwangirika neza. Mu gihe cy'ibidukikije bikwiye, udukoko dushobora gusenya ibinyampeke by'ibigori mo ibintu byoroheje by'umwimerere, amaherezo bikagera ku kwangirika kose. Ibi bituma ibinyampeke bya bioplastic bishobora kongera gukoreshwa mu buryo busanzwe nyuma yo gukoreshwa, bigagabanya ihumana ry'ibidukikije.

Ariko kandi, ibinyampeke by’ibigori nabyo bifite imbogamizi zimwe na zimwe. Urugero, mu bidukikije birimo ubushyuhe bwinshi cyangwa ubushuhe bwinshi, ibinyampeke bya bioplastike bishobora gutakaza ubusugire, bigira ingaruka ku gihe cyabyo n’imikorere yabyo. Kugira ngo iki kibazo gikemuke, abahanga mu bya siyansi barimo gukora ku gushaka inyongeramusaruro nshya cyangwa kunoza uburyo bwo gukora kugira ngo bongere ubushobozi bwo kurwanya ubushyuhe no kurwanya ubushuhe bwa bioplastike.

3. Imikoreshereze y'ifu y'ibigori muri Bioplastics yihariye

Uburyo ibinyampeke by'ibigori bikoreshwa mu bintu byihariye bya bioplastics buratandukanye bitewe n'imiterere y'ibyo wifuza n'uburyo byakoreshejwe mu gukoresha umusaruro wa nyuma. Dore ingero nke:

Acide Polylactic (PLA): PLA ni bioplastic ikunze kuva mu bigori. Ifu y'ibigori ikoreshwa nk'ibiribwa byo gukora aside lactic, hanyuma igahindurwa polymer kugira ngo ikore PLA. PLA ishyigikiwe na aside y'ibigori igaragaza imiterere myiza ya mekanike, nko gukomera no kudakora neza. Byongeye kandi, kongeramo aside y'ibigori bishobora kongera ubushobozi bwo kwangirika kwa PLA, bigatuma ikoreshwa mu gihe ibibazo by'ibidukikije ari byo by'ingenzi, nkoibikoresho byo gukoresha mu gihe runaka, gupfunyika ibiryo, na filimi z'ubuhinzi.

Polyhydroxyalkanoates (PHA): PHA ni ubundi bwoko bwa bioplastic bushobora gukorwa hakoreshejwe ifu y'ibigori nk'isoko ya karuboni. Ifu y'ibigori iterwa na mikorobe kugira ngo ikore polyhydroxybutyrate (PHB), ari na yo bwoko bwa PHA. PHA zongerewemo ifu y'ibigori zikunze kugira ubushyuhe bwiza kandi zifite imiterere myiza ya mekanike. Izi bioplastic zikoreshwa mu nzego zitandukanye, harimo gupakira, ibikoresho by'ubuvuzi, n'ubuhinzi.

Bioplastics ishingiye ku byokurya: Hari ubwo ibinyampeke by’ibigori bitunganywa mu buryo butaziguye bikavamo bioplastics bitabaye ngombwa ko habaho izindi ntambwe zo guhindura imiterere y’ibinyampeke. Bioplastics ishingiye ku byokurya ubusanzwe iba irimo uruvange rw’ibinyampeke by’ibigori, pulasitiki, n’ibindi bikoresho kugira ngo byongere ubushobozi bwo gutunganya no gukoresha neza. Ibi binyampeke bikoreshwa mu bikorwa nk’imifuka ikoreshwa rimwe, ibikoresho byo kurya, n’ibikoresho byo ku meza bikoreshwa rimwe.

Kuvanga n'izindi polima zishobora kubora: Ifu y'ibigori ishobora kandi kuvanga n'izindi polima zishobora kubora, nka polyhydroxyalkanoates (PHA), polycaprolactone (PCL), cyangwa polybutylene adipate-co-terephthalate (PBAT), kugira ngo hakorwe bioplastic ifite imiterere yihariye. Izi mvange zitanga uburinganire bw'imbaraga za mekanike, ubworoherane, no kubora, bigatuma zikoreshwa mu buryo butandukanye kuva ku gupfunyika kugeza ku buhinzi.

4. Umwanzuro

Uruhare rw'ibinyampeke by'ibigori mu binyampeke by'ibinyabuzima rurenze kongera imikorere; runafasha kugabanya kwishingikiriza kuri pulasitiki gakondo ishingiye kuri peteroli, bigatera imbere iterambere ry'ibikoresho bibungabunga ibidukikije. Hamwe n'iterambere mu ikoranabuhanga, twiteze kubona ibintu bishya bikomoka kuri pulasitiki bishingiye ku bintu bishobora kongera gukoreshwa nk'ibinyampeke by'ibigori.

Muri make, ibinyampeke by’ibigori bigira uruhare runini muri bioplastics, ntabwo byongera gusa imiterere ya pulasitiki ahubwo binateza imbere kwangirika kwayo, bityo bikagabanya ingaruka mbi ku bidukikije. Hamwe n’iterambere ry’ikoranabuhanga n’udushya, bioplastics yiteguye kugira uruhare runini mu kuzana inyungu nyinshi ku bidukikije by’Isi yacu.
