Recycling rates in Lincoln have doubled in the past two years, according to city council figures.
The recycling rate for the city shot up to 24.4% of all the waste collected from April 2004 to March this year.
The council said it compared to 17% in 2003/04, and just under 12% for the previous period.
Council leaders said the city's recycling rate was well on the way to being 30% in a year's time - the target set by the government for 2005/06.
Over the past 12 months about 2,500 tonnes of recycling was collected through the kerbside collection service and a further 1,300 tonnes deposited at recycling sites around the city.
Council recycling officer Barrie Billinghay said: "This is great news and thanks must go out to the city's residents who have actually given us all this material.
