Ifunguro rishyushye mumifuka ya plastike ni uburozi?

Twaba tujya muri resitora ya mugitondo cyangwa gutumiza ibyokurya, dukunze kubona ibi bintu: shobuja abigiranye ubuhanga yatanyaguye umufuka wa pulasitike, hanyuma awushyira ku gikombe, amaherezo ashyiramo ibiryo vuba.Mubyukuri, hari impamvu yabyo.: Ibiryo bikunze gusiga amavuta.Niba ikeneye gusukurwa, bivuze imirimo yinyongera.Kubucuruzi bwubucuruzi bw "ingano nini ninyungu nke" nko guhagarara mugitondo, umufuka wa pulasitike uhendutse urashobora kubazanira Byoroshye.
Ariko hariho n'abantu benshi barwanya cyane ibi, bibwira ko imifuka ya plastike ari "imiti".Ugereranije n’ibikombe bya farisari gakondo, bigaragara ko ari byiza hejuru, ariko mubyukuri, byangiza umutekano muke kubuzima.Cyane cyane iyo ushyizemo "ibiryo byubushyuhe bwo hejuru" nka noode hamwe nisupu bimaze kuva mu nkono, urashobora guhumurirwa neza numunuko wa plastike, ushobora kwakirwa utabishaka kumucyo, cyangwa gusubirana kandi bigoye kumira nabi, bigatera bimwe bidakenewe "amakimbirane".

None se imifuka ya pulasitike yaba ifite uburozi nyuma yo kuzura ibiryo bishyushye?
Mbere ya byose, ni ngombwa kumva ko imifuka ya pulasitike ikozwe muri “polyethylene”, “polypropilene”, “polyvinyl chloride” n'ibindi.Dufatiye ku mwuga, polyethylene ifite ibyago byo kugwa kwa "toxic monomer ethylene", ariko birashoboka ko imvura yagwa "polyethylene yo mu rwego rwo hejuru" iri hasi cyane.Imifuka ya pulasitike yakwirakwijwe mbere muri rusange ikozwe muri “polypropilene”, kubera ko ifite imbaraga zo guhangana n’ubushyuhe bwo hejuru (160 ° -170 °), kandi niyo yashyutswe na microwave, ntabwo izana impumuro idasanzwe.Ukurikije ubushyuhe bwo hejuru bw’ibiribwa kuri 100 °, nta “monomers zifite ubumara” ziri mu “mifuka ya pulasitike ya polypropilene”, ariko ikigaragara ni uko imifuka ya pulasitike yakoreshejwe igomba kuba “urwego rw’ibiribwa”.
Mu buryo bufite intego: ibyo bita "ibintu" muri "polypropilene" ntibisobanura ko ari imiti yuburozi.Nibyiza kutayarya, ariko ntugomba guhangayika cyane niba uyiriye.
