The council said there had been “technical problems” with the new specialist vehicles that collect the food waste, and issues with collection crews adjusting to the new process.
Ashton said: “We are frustrated by this, but we are working hard to resolve the remaining issues and ensure our residents understand what they can expect during this bedding-in period.”
He continued: “So, by providing reassurance that residents will receive a fortnightly food waste collection service, as a bare minimum during these early stages, we can provide some certainty for the time being.”
The council advised residents to bring their caddies back from the kerbside if they were not collected and put them out on their assigned day the following week.
It added that there was no need to report the missed collection.
The council stressed this was a temporary measure, but it could only guarantee a food waste collection every two weeks for the time being.
It said that if the large caddy became full, residents could place the extra food waste in their general waste bin for collection.
