Hamwe no kurushaho kumenyekanisha ingaruka z’ibidukikije by’imyanda ya pulasitike hamwe n’umutwaro wiyongereye ujyanye no kujugunya, hari gahunda yo gukoresha ibizunguruka aho gukoresha plastiki y’isugi aho bishoboka hose. Nkuko ibikoresho byinshi bya laboratoire bikozwe muri plastiki, ibi bitera kwibaza niba bishoboka guhinduranya plastiki zongeye gukoreshwa muri laboratoire, kandi niba aribyo, burya birashoboka.
Abahanga bakoresha ibikoresho bya pulasitiki mu bicuruzwa byinshi muri laboratoire no hafi yayo - harimo na tebes (Imiyoboro ya Cryovial,PCR tubes,Centrifuge tubes), Microplates (amasahani yumuco,24,48,96 isahani yimbitse, PCR), inama(Automatic or Universal tips), petri ibiryo,Amacupa ya Reagent,n'ibindi. Kugirango ubone ibisubizo nyabyo kandi byizewe, ibikoresho bikoreshwa mubikoreshwa bigomba kuba biri murwego rwo hejuru iyo bigeze ku bwiza, guhoraho, no kwera. Ingaruka zo gukoresha ibikoresho bitujuje ubuziranenge zirashobora gukomera: amakuru yavuye mubushakashatsi bwose, cyangwa urukurikirane rw'ibigeragezo, arashobora kuba impfabusa hamwe gusa kunanirwa gukoreshwa cyangwa gutera umwanda. None, birashoboka kugera kuri aya mahame yo hejuru ukoresheje plastiki yongeye gukoreshwa? Kugira ngo dusubize iki kibazo, dukeneye kubanza kumva uburyo ibi bikorwa.
Nigute plastiki ikoreshwa?
Kw'isi yose, gutunganya plastike ni inganda zigenda ziyongera, bitewe no kurushaho kumenya ingaruka imyanda ya pulasitike igira ku bidukikije ku isi. Ariko, hariho itandukaniro rinini muri gahunda yo gutunganya ibicuruzwa ikorera mu bihugu bitandukanye, haba mubipimo no kuyishyira mu bikorwa. Urugero, mu Budage, gahunda ya Green Point, aho abayikora bishyura amafaranga yo gutunganya plastike mu bicuruzwa byabo, yashyizwe mu bikorwa guhera mu 1990 kandi kuva yaguka no mu bindi bice by’Uburayi. Nyamara, mubihugu byinshi igipimo cyo gutunganya plastiki ni gito, igice bitewe ningorane nyinshi zijyanye no gutunganya neza.
Ikibazo cyingenzi mugutunganya plastike nuko plastike ari chimique itandukanye yibikoresho kuruta urugero, ikirahure. Ibi bivuze ko kugirango ubone ibikoresho byongeye gukoreshwa, imyanda ya pulasitike igomba gutondekwa mubyiciro. Ibihugu n'uturere dutandukanye bifite sisitemu yabyo yo gushyira mu byiciro imyanda ishobora gukoreshwa, ariko benshi bafite ibyiciro bimwe bya plastiki:
- Polyethylene terephthalate (PET)
- Polyethylene yuzuye cyane (HDPE)
- Polyvinyl chloride (PVC)
- Polyethylene nkeya (LDPE)
- Polypropilene (PP)
- Polystirene (PS)
- Ibindi
Hariho itandukaniro rinini muburyo bworoshye bwo gutunganya ibyiciro bitandukanye. Kurugero, amatsinda 1 na 2 biroroshye gusubiramo, mugihe icyiciro 'ikindi' (itsinda 7) ntabwo gikunze gukoreshwa5. Hatitawe ku mubare w'itsinda, plastiki yongeye gukoreshwa irashobora gutandukana cyane na bagenzi babo b'isugi mu bijyanye cyangwa ubuziranenge n'imiterere ya mashini. Impamvu yabyo nuko na nyuma yo gukora isuku no gutondeka, umwanda, haba mubwoko butandukanye bwa plastiki cyangwa mubintu bijyanye no gukoresha ibikoresho mbere, bigumaho. Kubwibyo, plastike nyinshi (zitandukanye nikirahure) zisubirwamo rimwe gusa kandi ibikoresho bisubirwamo bifite porogaramu zitandukanye na bagenzi babo b'isugi.
Nibihe bicuruzwa bishobora gukorwa muri plastiki ikoreshwa neza?
Ikibazo kubakoresha laboratoire ni iki: Bite kubakoresha laboratoire? Hariho uburyo bwo gukora laboratoire yo mu rwego rwa laboratoire ivuye mu bikoresho bitunganijwe neza? Kugirango umenye ibi, birakenewe ko ureba neza imitungo abakoresha bategereje kubikoresha muri laboratoire n'ingaruka zo gukoresha ibikoresho bitujuje ubuziranenge.
Icy'ingenzi muri iyi mitungo ni ubuziranenge. Ni ngombwa ko umwanda uri muri plastiki ukoreshwa mubikoresho bya laboratoire ugabanuka kuko ushobora kuva muri polymer no mubitegererezo. Ibi byitwa leachables birashobora kugira ingaruka zingaruka zidateganijwe kurugero, imico ya selile nzima, mugihe kandi bigira ingaruka kubuhanga bwo gusesengura. Kubwiyi mpamvu, abakora laboratoire ikoreshwa buri gihe bahitamo ibikoresho hamwe ninyongera nkeya.
Ku bijyanye na plastiki yongeye gukoreshwa, ntibishoboka ko abayikora bamenya inkomoko nyayo y'ibikoresho byabo bityo ibyanduye bishobora kuba bihari. Kandi nubwo abayikora bashira imbaraga nyinshi mugusukura plastike mugihe cyo gutunganya ibicuruzwa, ubuziranenge bwibikoresho bitunganyirizwa ni bike cyane ugereranije na plastiki yisugi. Kubera iyo mpamvu, plastiki yongeye gukoreshwa ikwiranye nibicuruzwa bidakoreshwa ningaruka nke ziva. Ingero zirimo ibikoresho byo kubaka amazu n'imihanda (HDPE), imyambaro (PET), hamwe nibikoresho byo gupakira (PS)
Nyamara, kubikoresha muri laboratoire, kimwe nibindi bikorwa byoroshye nkibikoresho byinshi-bihuza ibiryo, urwego rwubuziranenge bwibikorwa byo gutunganya ibintu ntabwo bihagije kugirango byemeze ibisubizo byizewe, byororoka muri laboratoire. Mubyongeyeho, optique isobanutse neza hamwe nubukanishi buhoraho nibyingenzi mubikorwa byinshi bya laboratoire ikoreshwa, kandi ibyo bisabwa nabyo ntibihagije mugihe ukoresheje plastiki yongeye gukoreshwa. Kubwibyo, gukoresha ibyo bikoresho bishobora kuganisha kubintu byiza cyangwa bibi mubushakashatsi, amakosa mu iperereza ryubucamanza, no kwisuzumisha nabi.
Umwanzuro
Gutunganya plastike ni uburyo bwashyizweho kandi bugenda bwiyongera ku isi yose bizagira ingaruka nziza, zirambye kubidukikije mugabanya imyanda ya plastike. Mubidukikije bya laboratoire, plastiki yongeye gukoreshwa irashobora gukoreshwa mubisabwa bidashingiye cyane kubuziranenge, urugero nko gupakira. Nyamara, ibisabwa kubikoresho bya laboratoire mubijyanye nubuziranenge no guhoraho ntibishobora kubahirizwa nuburyo bugezweho bwo gutunganya ibicuruzwa, bityo rero ibyo bintu bigomba gukorwa muri plastiki yisugi.
