More than 9,500 households across Boston, South Holland and North Kesteven will have to separate card and paper from the rest of their recycling as part of a new trial.
The three district councils will run the Lincolnshire Joint Municipal Waste Management Strategy’s pilot from September.
Bosses at Lincolnshire County Council, who will fund the project, say 30% of recycling throughout the county is currently contaminated.
A new engagement officer will also be employed for the trial period, working 37 hours a week.
Lincolnshire County Council, which will buy bins for Boston and North Kesteven, has not revealed the costs yet – calling them “commercially sensitive” as contracts have yet to be agreed.
South Holland District Council which uses bags however, says the cost of the scheme should be £4,000 for blue sacks, £2,500 for delivery and £400 per fortnight to split the sacks.
Its cabinet will examine the plans next Tuesday.
