Igikombe cyamazi ya plastike nibintu bisanzwe bikoreshwa mubuzima bwacu bwa buri munsi. Ni ngombwa cyane guhitamo ibikoresho bifite umutekano. Ibikurikira ningingo yerekeye ibikoresho byumutekano byibikombe byamazi ya plastike.
Mugihe abantu bitaye cyane kubuzima no kurengera ibidukikije, abaguzi benshi baritondera guhitamo ibikoresho byibikombe byamazi. Umutekano nimwe mubitekerezo byingenzi muguhitamo icupa ryamazi ya plastike. Iyi ngingo izamenyekanisha ibikoresho byinshi byamazi ya plastike kandi yibanda kubibazo byumutekano.
Mbere ya byose, polyethylene (PE) ni ibikoresho bisanzwe byigikombe cyamazi. Ifite ubushyuhe buke kandi bwo hejuru kandi ntibisohora ibintu byangiza. Amacupa yamazi ya polyethylene arashobora gukoreshwa mugutwara ibinyobwa bishyushye cyangwa bikonje kandi bifite umutekano kandi byizewe. Byongeye kandi, polyethylene ni plastiki ishobora gukoreshwa kandi yangiza ibidukikije.
Icya kabiri, polypropilene (PP) nayo ni ibikoresho bisanzwe bya gikombe cyamazi. Kimwe na polyethylene, polypropilene ifite ubushyuhe bwinshi kandi irwanya imiti. Kubwibyo, amacupa yamazi ya polypropilene nayo ni amahitamo meza. Mu buryo nk'ubwo, polypropilene nayo ni plastiki ishobora gukoreshwa kandi yangiza ibidukikije.
Ariko, ibikoresho bimwe bya pulasitike ntibishobora kuba nkibikoresho byamazi. Kurugero, polyvinyl chloride (PVC) ni plastiki isanzwe, ariko irashobora kurekura ibintu byangiza nka plastike. Iyi miti irashobora kwangiza ubuzima bwabantu. Kubwibyo, mugihe uhisemo amacupa yamazi ya plastike, gerageza wirinde gukoresha ibikoresho bya chloride polyvinyl.
Byongeye kandi, polystirene (PS) nayo ni ibikoresho bisanzwe bya plastiki, ariko irumva ihindagurika ryubushyuhe. Polystirene irashobora kurekura ibintu byangiza mubushyuhe bwinshi, bigatuma bidakwiye ibinyobwa bishyushye. Nubwo amacupa yamazi ya polystirene ahendutse ukurikije igiciro, duhereye kumutekano, turasaba guhitamo ibindi bikoresho.
Byongeye kandi, hari plastiki ishobora kwangirika yitwa melamine (PLA), nayo yakoreshejwe cyane mugukora ibikombe byamazi ya plastike mumyaka yashize. PLA ikomoka mubishobora kuvugururwa nka krahisi y'ibigori kandi ifite umutekano kandi ntacyo itwaye kubantu. Mugihe cyo gukoresha, ibikombe byamazi ya PLA ntibizatanga ibintu byangiza cyangwa ngo bitere umwanda kubidukikije. Kubwibyo, amacupa yamazi ya PLA ni amahitamo meza kandi yangiza ibidukikije.
Hanyuma, ntakibazo cyaba gikombe cyamazi cya plastike wahisemo, turasaba gukurikiza amahame akurikira nogukoresha:
1. Ntugashyire amacupa yamazi ya plastike ahantu h’ubushyuhe bwo hejuru kugirango wirinde kubora no gushonga ibikoresho bya plastiki.
2. Sukura amacupa yamazi ya plastike buri gihe kugirango wirinde umwanda usigaye no gukura kwa bagiteri.
3. Irinde gukoresha ibikoresho bikarishye kugirango wirinde guhungabanya umutekano wibikoresho bya plastiki.
4. Niba igikombe cyamazi cyangiritse cyangwa cyashaje, kigomba gusimburwa mugihe kugirango wirinde gukoresha ibikombe byangiza ubuzima.
Muri make, polyethylene na polypropilene ni ibikoresho bisanzwe byuzuye amacupa yamazi ya plastike, mugihe polyvinyl chloride na polystirene bigomba kwirindwa bishoboka. Mubyongeyeho, ibinyabuzima byangiza ibinyabuzima PLA nabyo ni amahitamo meza kandi yangiza ibidukikije. Mugihe uhisemo igikombe cyamazi ya plastiki, nyamuneka witondere umutekano wibikoresho kandi ukurikize imikoreshereze yukuri nogukurikiza. Muri ubu buryo, urashobora guhitamo icupa ryamazi meza kandi yizewe kandi ukishimira ubuzima bwiza.
