Mubuzima bwa buri munsi, tuzasanga ibicuruzwa byinshi bya pulasitike bizagira umunuko mugihe byakoreshejwe bwa mbere.Kurugero, bimwe mubisanzwe polyethylene na polypropilene bizaba bifite impumuro yumwotsi mugitangira gukoreshwa, kandi impumuro izaba nkeya nyuma yigihe cyo kuyikoresha., Kuki ibyo bicuruzwa bya pulasitike binuka?
Iyi mpumuro muri plastiki ahanini ituruka ku nyongeramusaruro zongewe mubikorwa byo gukora plastike.Ibi biterwa no kongeramo ibishishwa hamwe nintangiriro nkeya yabatangije nibindi byongerwaho mugihe cya polymerisation ya polyethylene na polypropilene.Nyuma yo gukaraba, kuyungurura, nibindi, rimwe na rimwe umubare muto wabafasha bavuzwe haruguru uzagumaho, kandi wongeyeho, umubare muto wa polymer-uburemere buke bwa polymer uzaguma muri resin.Mugihe cyo kubumba no gutunganya ibicuruzwa bya pulasitike, ibyo bintu bizahura nubushyuhe bwinshi kugirango bahunge umunuko utamenyereye kandi ugume hejuru yibicuruzwa.
Byongeye kandi, ababikora bamwe bazongeramo turpentine nkimfashanyo yo gusiga irangi mugihe cyo gusiga irangi.Niba ikoreshwa cyane, impumuro ya turpentine nayo izahunga ibicuruzwa.Irazimira buhoro kandi nta ngaruka igira ku buzima bwabantu.Ariko, niba umunuko uremereye kandi ukabaho igihe kirekire, bizakomeza kugira ingaruka runaka kubuzima bwabantu.
Kubwibyo, mugihe tuguze ibicuruzwa bya pulasitike, tugomba guhitamo ibicuruzwa bya pulasitiki bifite ibikoresho bibisi bifite umutekano, ubuziranenge bwiza nibintu byumutekano muke.
