Iinkqubo zemibhobho yePolyethylene zisetyenziswe ngabathengi bethu kunikezelo lwamanzi okusela ukusukela oko yasungulwa ngeminyaka yoo-1950.Ishishini leplastiki lithathe uxanduva olukhulu ekuqinisekiseni ukuba iimveliso ezisetyenziswayo aziwuchaphazeli kakubi umgangatho wamanzi.

Uluhlu lovavanyo olwenziwa kwimibhobho ye-PE ludla ngokuquka incasa, ivumba, inkangeleko yamanzi, kunye novavanyo lokukhula kwezinto ezincinci zasemanzini.Olu luhlu olubanzi ngakumbi lovavanyo kunolo lusetyenziswa ngoku kwimathiriyeli yemibhobho yemveli, njengesinyithi nesamente kunye neemveliso ezinemigca yesamente, kumazwe amaninzi aseYurophu.Ngaloo ndlela kukho ukuzithemba okukhulu ukuba umbhobho we-PE ungasetyenziselwa ukunikezelwa kwamanzi okusela phantsi kweemeko ezininzi zokusebenza.

Kukho umahluko othile kwimithetho yelizwe kunye neendlela zovavanyo ezisetyenziswa phakathi kwamazwe aseYurophu.Ukwamkelwa kokusetyenziswa kwamanzi okusela kunikezelwe kuwo onke amazwe.Ulwamkelo lwamaqumrhu alandelayo amkelwa kwamanye amazwe aseYurophu kwaye ngamanye amaxesha ngakumbi kwihlabathi jikelele:

Iikhompawundi zemibhobho ye-PE100 kufuneka zenziwe ukuba zisetyenziswe kwizicelo zamanzi aselwayo.Ngaphaya koko, umbhobho we-PE100 unokuveliswa ukusuka kwikhompawundi eluhlaza okwesibhakabhaka okanye emnyama enemigca eluhlaza ebonisa ukuba ifanelekile ukuba isetyenziswe kusetyenziso lwamanzi aselwayo.

Ulwazi oluthe vetshe malunga nolwamkelo lokusetyenziswa kwamanzi aselwayo lunokufunyanwa kumenzi wemibhobho ukuba kuyafuneka.

Ukuze ukulungelelanisa imimiselo kunye nokuqinisekisa ukuba zonke izinto ezisetyenziselwa ukudibana namanzi okusela ziphathwa ngendlela efanayo, i-EAS European Approval Scheme iyaphuhliswa, ngokusekelwe kwiKhomishini yaseYurophu.

Umyalelo 98/83/EC.Oku kulawulwa liqela le-European Water Regulators, i-RG-CPDW - iQela loLawulo lweeMveliso zoKwakha ngokuQhagamshelana naManzi okuSela.Kujongwe ukuba i-EAS iya kuqala ukusebenza ngo-2006 ngendlela elinganiselweyo, kodwa kubonakala ngathi ayinakwenzeka into yokuba iphunyezwe ngokupheleleyo kude kube ngumhla osemva kakhulu xa iindlela zovavanyo zikhona kuzo zonke izixhobo.

Imibhobho yePlastiki yamanzi okusela ivavanywa ngokungqongqo liLizwe ngalinye leLungu le-EU.Umbutho wabathengisi bezinto eziluhlaza (iPlastiki yaseYurophu) kudala ikhuthaza ukusebenzisa iiplastiki zoqhagamshelwano lokutya kwizicelo zamanzi okusela, kuba imithetho yoqhagamshelwano lokutya iyona nto ingqongqo ekukhuseleni impilo yabathengi kunye nokusetyenziswa kovavanyo lwetyhefu njengoko kufunwa kwizikhokelo zeKomiti yeSayensi yeKhomishini yaseYurophu. yoKutya (enye yeekomiti ze-EU yeMigangatho yoKutya).Ngokomzekelo, iDenmark isebenzisa umthetho wokuqhagamshelana nokutya kwaye isebenzisa iindlela ezongezelelweyo zokhuseleko.Umgangatho wamanzi okusela waseDanish yenye yezona zinto zinzima kakhulu eYurophu.
