Derby City Council has been forced to spend £50,000 on extra efforts to resolve problems with its new recycling collection system.
The council launched a change to its refuse collections in January in order to make rounds more efficient and increase recycling rates by adding an extra 6,000 properties to its kerbside recycling service.
However, in the initial stages of the new collection system, there were problems with around 1,000 bins being missed and, in one area of the city, items of household recyclable waste were mixed with black bin waste.
We are experiencing the most fundamental change to our bin rounds for 15 years, said Derby City Council director for environmental services Paul Robinson.
Since starting the new service, we have experienced problems which have resulted in around 1,000 bins being missed this represents less than 1% of the 180,000 bins we successfully collect each week.
We have put on extra crews and are working Saturdays to deal with this backlog. The £50,000 has been spent on extra efforts to resolve these problems.
The council is also keen to point out that the recyclable and black bin waste mix-up is being dealt with and will not have an impact on overall recycling rates in Derby.
Robinson said: When this came to light, it was immediately stopped and we are dealing with the matter internally.
Derbys recycling rate stands at 43% of all waste and this isolated incident will not affect that rate.
The council has a special 24 hour waste collection service number that residents can call if their bin has not been collected. This number has even been advertised on the councils Twitter feed.
Robinson said: We are confident that once these initial problems are resolved, we will have a much better service with more people being able to join our kerbside recycling scheme.
