Guhitamo ikigega gikwiye cyo hanze cy’imyanda cya pulasitiki ni ingenzi cyane kugira ngo kirambe, kigire akamaro, kandi kibungabunge ibidukikije. Byaba ari mu midugudu ituwemo, mu duce tw’ubucuruzi, muri pariki, cyangwa mu duce tw’inganda, guhitamo neza bishobora kunoza imikorere myiza yo guta imyanda, kugabanya ikiguzi cyo kuyibungabunga, no kubungabunga isuku y’ibidukikije. Iyi nyandiko izasobanura ibintu by’ingenzi ugomba kwitaho mu gihe uhitamo ibigega byo hanze by’imyanda bya pulasitiki, harimo guhitamo ibikoresho, imiterere y’ibyiciro, no guhuza ingano, bigufasha gufata icyemezo ukurikije amakuru.
Ikintu cy'ingenzi cya 1: Guhitamo ibikoresho - Ishingiro ryo kuramba
Ibikoresho bya pulasitiki byo hanze bigena mu buryo butaziguye igihe bikoreshwa, uburyo bikoreshwa, n'umutekano wabyo. Ibikoresho bitandukanye bya pulasitiki bifite imiterere itandukanye, bityo ni ngombwa kubihuza n'uburyo byihariye bwo kubikoresha.
1. Polyethylene ifite ubucucike bwinshi (HDPE)
Nk'ibikoresho bikunze gukoreshwa cyane, HDPE ifite ubukana bwinshi, gukomera cyane, no kurwanya aside na alkali cyane. Ikwiriye kubika imyanda yo mu gikoni, imyanda yo mu rugo, n'indi myanda isanzwe. Akamaro kagaragara ka HDPE ni uko irwanya ubushyuhe buke, ikarinda kwangirika ndetse no mu duce dukonje, bigatuma iba nziza cyane gukoreshwa hanze mu turere twinshi.
2. Polypropylene (PP)
Ibikoresho bya PP bitanga ubushobozi bwo kwihanganira ubushyuhe bwinshi ugereranije na HDPE, bikaba bishobora kwihanganira ubushyuhe bwinshi. Ibi bituma biba byiza cyane ahantu hashobora kuboneka amazi ashyushye cyangwa imyanda ishyushye cyane, nko hafi ya resitora, aho bacumbika, cyangwa aho batunganya ibiryo. Ariko, ni ngombwa kumenya ko PP ifite ubukana buke mu bushyuhe buke, bityo ishobora kuba atari yo mahitamo meza yo gukoreshwa hanze mu turere dukonje cyane.
3. Polyvinyl Chloride (PVC)
PVC ni ibikoresho bya pulasitiki bihendutse, ariko ntibihindagurika neza. Ishobora kurekura ibintu byangiza iyo ihuye n'ubushyuhe bwinshi, bigatera ingaruka mbi ku bidukikije no ku buzima bw'abantu. Muri iki gihe, PVC ntikunze gukoreshwa mu myanda yo hanze ihura n'imyanda yo mu ngo, kandi ntiyemerwa ku bantu benshi basura hanze.
Ikintu cy'ingenzi cya 2: Imiterere y'ibyiciro – Birenze “Byongera gukoreshwa” n' “Ibindi”
Bitewe n’iterambere rya politiki yo gushyira imyanda mu byiciro, amasanduku y’imyanda ya pulasitiki yo hanze agezweho ntabwo akiri amasanduku manini gusa. Imiterere yayo yo gushyira mu byiciro irimo ibintu byiza bigamije guhaza ikoreshwa ry’imyanda itandukanye no kunoza imikorere myiza yo kuyitondekanya.
1. Uruvange rw'indobo ebyiri/indobo eshatu
Iyi ni yo shusho ikunze gukoreshwa cyane mu gushyira mu byiciro. Ihuriro risanzwe ririmo "Ishobora kongera gukoreshwa + Indi myanda" na "Imyanda yo mu gikoni + Imyanda iteje akaga + Indi myanda." Izi myanda zikoresha ibara risobanutse neza (ubururu ku bintu bishobora kongera gukoreshwa, icyatsi kibisi ku myanda yo mu gikoni, umutuku ku myanda iteje akaga, imvi ku yindi myanda, nibindi), bituma rubanda rubasha kumenya no gutondekanya imyanda neza.
2. Igishushanyo mbonera gifite umupfundikizo
Amacupa y'imyanda afite umupfundikizo afite ubushobozi bwo gufunga neza, bishobora kugabanya impumuro mbi. Anabuza amazi y'imvura kwinjira mu ndobo kandi akabuza imibu n'isazi kororoka, bigatuma biba byiza cyane mu kubika imyanda yo mu gikoni cyangwa gukoreshwa ahantu hashyushye hanze.
3. Ifungura ry'Umupfundikizo Ukoresha Ibirenge
Imiterere y’ikirenge yemerera abayikoresha gufungura umupfundikizo batawukozeho n’amaboko yabo, binongera cyane isuku. Ubu bwoko bw’imyanda bukoreshwa cyane ahantu hahurira abantu benshi hakenewe isuku nyinshi, nko mu bitaro, mu maduka, no mu mashuri y’incuke.
4. Amasanduku afite ubushobozi bunini ahujwe
Ikunze kuboneka ahantu hahurira abantu benshi nko mu bibuga, ahantu nyaburanga, no muri sitade, imiyoboro myinshi y'amasanduku irahujwe. Iyi miterere ntigaragaza gusa ko ishyira mu byiciro bisobanutse neza ahubwo inazigama umwanya, bityo ikaba yorohereza abakozi b'isuku gukusanya no gutwara abantu.
Ikintu cy'ingenzi cya 3: Guhuza ingano – Hitamo ukurikije uko porogaramu ikoreshwa
Ingano y'amabati ya pulasitiki yo hanze igira ingaruka ku buryo ataziguye ku mikoreshereze yayo n'uburyo ikoreshwa. Guhitamo ingano ikwiye hakurikijwe uko ikoreshwa bishobora kwirinda ibibazo nko kudahagije k'ubushobozi cyangwa gukoresha umwanya urenze urugero.
1. Inzira z'abaturage/Inzira zo kwinjira mu byumba
Udusanduku duto tw’imyanda dufite ubushobozi bwo gutwara litiro 30-50 turakwiriye hano. Ni duto kandi ntidufata umwanya munini, bigatuma abaturage boroherwa no kujugunya imyanda ya buri munsi.
2. Imihanda/Inzira zo muri Pariki
Amasanduku y'imyanda aringaniye afite ubushobozi bwo gutwara litiro 80-120 arasabwa. Ubushobozi bwayo ni buke, bushobora guhaza ibyifuzo by'abanyamaguru mu gihe atari manini cyane ku buryo yagira ingaruka ku bwiza bw'ibidukikije.
3. Ibibuga/Ibibanza byiza/Ibibuga by'imikino by'ishuri
Ahantu hakunze kugaragara urujya n'uruza rw'abantu benshi hakenewe amasanduku y'imyanda afite ubushobozi bwo gutwara litiro 150-240. Ibi bishobora kugabanya inshuro zo kuyatwara no kuyatwara ndetse no kwirinda imyanda ku
Kugira ngo uhitemo agasanduku k'imyanda gakwiye ko hanze gakoreshwa muri pulasitiki, ugomba gusuzuma ibintu bitatu by'ingenzi: ibikoresho, imiterere y'ibyiciro, n'ingano. Shyira imbere ibikoresho bya HDPE cyangwa PP hashingiwe ku bidukikije; hitamo imiterere ikwiye yo gushyira mu byiciro hakurikijwe ibisabwa mu gutunganya imyanda n'amahame y'isuku; kandi uhuze ingano n'ingano y'imodoka n'imiterere y'aho ikoreshwa. Ukurikije aya mahame, ushobora guhitamo agasanduku k'imyanda gakomeye, gafite akamaro kandi katangiza ibidukikije, bigatuma ibidukikije byo hanze birushaho kuba byiza kandi bifite gahunda.
