In the past two months the cost to the taxpayer has been £40,000 as 19 wagon loads of blue bin recycling have been rejected because of contamination.
Through The Deal, by residents recycling more and recycling right, the council can keep council tax low.
It costs Wigan Council up to £2,000 for each contaminated load.
The blue bin is used to recycle paper and cardboard only but Wigan Council is finding the wrong items are more frequently being put in the bin, with nappies and leftover pizza being the biggest culprit.
Blue bins containing contamination will be labelled with a red contamination sticker. The stickers will give the reason why the bin has not been collected.
Residents can be issued with a section 46 notice for having contaminated bins after which a fixed penalty notice can be issued.
Cllr Clive Morgan is encouraging residents to help reduce contamination. Nappies should be placed in the black bin and all food should be placed in the green bin. Magazines can be placed in the blue bin but please remove plastic wrapping.
Help and advice can be given to residents who are unsure or confused what goes in what bin by contacting the council on 01942 404364 or visit here for more details.
